Speed Passion Reventon-R Problems

[Muzzie]

Please could anyone give me some advice as I’ve been having a few issues with my new SP Reventon R ESC and SP V3 7.5t motor set-up.

I installed this into my Cougar SV using the kit standard spur gear and 23t pinion. I’ve run the car indoors for 3 week at my local club with no issues and was really impressed with its performance :thumbsup:. However, 2 weeks ago I ran at the east mid regional’s (West Bridgford) and in the first heat after two rounds of practice, the car stopped. My first thought was the thermal protection had cut in because it was a hot day. I checked the temperatures ESC = 56◦C and Motor 62◦C, all in normal parameters. In round two, the car seemed great until the last lap, where the car, didn’t stop but acted like the lipo was flat. Again, I took the car off the track, check the temperature and lipo battery (SP 6200mah 65c 2 month old) all was fine, I switched the ESC on and off and the car burst into life again. To try in fix the problem, I re-binded the receiver and ESC to the radio. This seemed to work and raced the rest of the day problem free.

After a frustrating day, I thought it might be worth updating the firmware to see if that would solve the glitch. After hours of messing about, it was done. I ran the car last night at my local club and for an hour of hard practice the car was faultless. However, again in round 1 the car started to glitch, but this time, when I released the throttle the car would surge forward on its own. (For INFO I have a power cap fitted). Again, I re-binded and all was well.

This is start to really grind my gears and I’m not sure what else to do apart from return the ESC to the shop, but this will mean I will be without a car for about a month and I think it would be impossible to diagnose.

Any ideas?

[Androiddave]

Have you had any luck with this?? I have the exact same problem!

My mate runs the same and his runs perfectly fine!

[Big paul]

Are you running lipo cut off. It my be as you are accelerating the lipo may be briefly dropping below your settings. Thus sending the ecs into sensorless mode, ie like the lipo is flat.

[Aran]

Might be a worth an email or call to Schumacher if its a common problem. They will be able to help

[Androiddave]

I spoke to schumacher and speed passion and both have said its a faulty motor no doubts!

I have sent mine for repair today so fingers crossed it solves the problem.

[JustARcFan]

With what motor did you have this problem?

[Androiddave]

Speed Passion v3 6.5t.

[Cardnim]

Keep us updated when you hear back - would be really useful to know if that cures the prob.

Good luck

[JustARcFan]

Seems that there is only a problem with motors like a 6.5 or lower.

I did some testing with mine and I only had problems with my LRP X20 6.5.
With the SP 7,5 and 8,5 everything is fine.

[Androiddave]

Yeah My mates got the same set up but with a 7.5 and no issues.

Should of chucked my motor in his car before sending it off really.

[Muzzie]

I'm running SP 7.5 V3 and after I updated the firmware for the 2nd time I've not had a problem (touch wood). Also for info, I have the Lipo protection turn off.

When I contacted Schumacher they gave me no advice other than return it and we with take a look :thumbdown:.

I'll keep you updated

[Androiddave]

This could be another problem then! I have updated my firmware but my friend hasnt!

I did not run mine before though so cant say for sure that it is that.

I will see what they say when my motor comes back.

[JustARcFan]

The reventon R also only has an output of 70amp.
This combined with a Savox servo could also have something to do with it.
Maybe this is also an issue when going for a 6.5 or lower??

[Androiddave]

Just got off the phone to JE Spares and schumacher have tested my motor with no issues found! So next step is to rule out the savox! I have also bought a power cap to see if that helps. I will keep you updated.

[Androiddave]

Ok, So here is the results!

Motor back after being tested as 100% fine! Put it back in the cougar along with the glitch buster and it still cuts outs!

My next step is thermal cut off! Will it be safe to turn off??

Cheers

[russmini]

What about the LiPo cut off? If you only ever race for 5 mins or so, then take it off, that could be your problem...

[Androiddave]

I dont think it can be that! I checked the battery the moment it cut out and it had 3.85v per cell.

Cut off is on 3.2....

[RudolfXC]

I dont think it can be that! I checked the battery the moment it cut out and it had 3.85v per cell.

Cut off is on 3.2....


The battery is probably close to being dead at that Voltage as you are measuring it open circuit but not under load. Under load, a battery with low rating will probably dip to 6.4V with a low turn motor.

[russmini]

Unless you were sat in the car or had measuring equipment on board, you would not have been able to measure it when it actually happened. Maybe within 20-30 seconds, after you'd ran off the rostrum, took the body off, got a volt checker and then checked it...

Turn it off and see how it goes. Then you'll know for sure.

:)

When I wanted to get a Reventon R at Speedpassion Europe, Toni Rheinard did not want to sell me one due to the immense software problems and recommended getting the GT2.0Pro instead (which of course does not properly fit in my B-Max2). AFAIK the next big update is scheduled for early August, and I keep my fingers crossed that it will fix your problems and gives me the opportunity to get a glitch-free Rev R; the GM Recing Genius Sport 80R/120R also seem nice and small enough (very similar to or maybe even identical with the Vampire Racing ESCs).
In the meantime I'll speed up my Cirtix-controlled Yoke with a 9.5 Thunder Power motor, the 13.5R will be an upgrade for my son.

[JustARcFan]

I had exactly the same problems with this esc.
Send it back a few days ago but no reply yet.

[Androiddave]

Ok, Let me know what they say. Will be good to get to the bottom of it!

Do you use a savox?

[JustARcFan]

I've switched the savox for a futaba, changed motor, receiver, transponder. Everything! :woot:

I'm very curious how they going to solve this.

[TDMAK]

I am having issues with my revention S and a Savox servo. I never had issues using savox servos with other speed passion and Novak esc's I am going to run a load test on the revention esc to see if the 2A rating is for real. At this point I want to go back to a GT2.0 pro (smoked)...

[Androiddave]

Quick update. Turned off thermal cut off..... Ran last night for a good solid 30-35 mins and nothing! didnt glitch, cut out or anything!

so maybe the thermal cut out is set wrong? Hopefully an update will fix it. :thumbsup:

[Solara]

Just a suggestion...

TURN OFF THERMAL cutoff....thermal cutoff is a feature to protect ESC overheating, not preventing the MOTOR overheating. I have heard that alot of ppl saying this function is protecting the MOTOR from overheating, and that is NOT TRUE. I never use this function.

2nd..turn off LIPO CUTOFF.........I never use that function. If my lipo is charged, and it is good quality lipo, it never need that cutoff, if I am only using it for 5 minutes practice and 5-6 minutes of racing...I never have this function turned on.

These function are they because it is a liability issue....it need to be there. But if you are going for a real racing, turn them off...and race that 6 minutes and should NOT have any shut down or slow down issue...

Running the car for 30 minutes is pointless....tires are overheated, lipos is over used, motor is hot...car is horrible to drive after 7 minutes and driver should be tired standing for more then 7 minutes.

My 2 cents...

[RudolfXC]

I don't know about Speed Passion but LRP SXX ESCs do monitor motor temperatures and cuts out if it gets too hot.

[shaun m]

how are people getting on with there reventon r esc's now then ??

Ive used mine for the first time in my cat sx3 with novac ss 5.5t , ace ds 1015 servo , and to be tottaly honest im not pleased with it :cry:

I tried loading the 119mod software using my 2in1 lcd program box , and that wont work , soo then installed the stock01 software on it ..

had it on the same gearing /track , and the esc is getting really hot , also was playing about with the esc settings , to try and cool it down to no avail !!

and the other thing im dissapointed with, when going thro the esc setting using the led program card , some of the values are not revelant to the things your trying to change !! and as said above , would had been nice to be able to use the lcd box ( as you know what settings your changing ) and to upload to older software ...

soo very dissapoined :mad::cry: and will have to splash out for another esc ... rant over !! :)

[Howler]

I had this when i had a Reventon R, thermal cut-off came in really when it was barely warm.

However this ESC completely fried within three rounds of racing, running a 6.5 in a 22 with the Losi recommended gearing. PoS in my opinion, avoid. Replaced it with an LRP SXX TC spec V2 and havent had a problem in the months i've been running that.

I've been reading the Speed Passion threads on the RCTech Forum !
There's a lot a chat about the S and R ESC's and the low BEC output.
It seems to be causing a few problems with high output servos like Savox.

Also I seem to remember reading about the LED card's values being mixed up, think it was values 4 and 5 were around the wrong way. The advice seems to be get the Reventon LCD Card as you can see what you are changing as it tell you on screen, the LED just shows the number !

Also seem to remember reading that 99% of drivers are turning off both the Lipo and Thermal cutoffs Off !!

Just put one in my son's X2C with a LRP 7.5T motor. He ran it last Saturday at Silverstone and loved it. He said it was very smooth and mental on the straight compared to his old Novak GTB. Motor and ESC were cool. This was using MOD1 software, zero timing and DDRS on 5. LED box worked fine for us although I agree the LCD box would be better. Maybe 5.5T motor is too close to the ESC's limit.

cheers for your help mate :) , one of the settings that was wrong was the thermal cut off , ( its meant to have 2 choices , and it went up to 9 !! ) , i had it on ( what i thought it was ) 95c and the lipo cut off was on 3.2v

is it only meant to be on the s and r's then ? ..

the only thing i remember , was my servo going really slow , when the esc got warm !! , now its cooled down its all working ok , just wish i could put the 119mod software on it , as that was what i was running on my old esc

Ok chap,
Think I may have read this right !
The Reventon R is a 70A ESC and rated down to 5.5 motor
But also read this !

Reventon R Stock 1 V18 firmware:
STO1 - for Hybrid Boost Technology ( for 7.5R to 10.5R Motorturn )


So if i'm reading this right, with the new V18-19 Firmware the motor limit is up't to a 7.5 Motor.

Think you cooked the esc chap !

[farmboy]

Interesting - I've just installed one in my X4 TE, with a SP Ultra Sportsman V3 10.5T motor.

Even when holding the car in one hand, repeatedly blipping the throttle was enough to make the motor stop dead after a few seconds.

Out on the track, it lasted only a few seconds (less than half a lap) before cutting out. Turning off/on was enough to bring it back to life.

I tried changing the sensor lead with no luck, Then a friend lent me an old SP 10.5 of his own which I dropped in. No problems at all!

I've yet to contact the shop where I bought it but that's on cards first thing in the morning. I think I had a duff motor. I'll let you know what happens next.

no , dont think soo , i have a pdf on my computer , but cant upload it on here , but it says for stock01 , its targeted at 4.5 to 10.5t

yeah thats different to the one i have on my computer , but im trying to upload it
the one that i have definately says , its targeted at 4.5t-10.5t , using a "r" esc and its a worded document and not a set up sheet .....

[Mugenextreme]

Had a chap racing new reventon r at are track today have similar problems with his speed
like outlined in previous posts. Car was cuttin or lossing boost at random times and acelerating randomly. switching on and off fixed it for short periods of time but in the end it was a waste of time as.the issue would happen a min or two later again. This was in a touring car running a lrp 10.5 motor using stock 01. Think its a savox low profile serv0. The termal was off and the lipo cut off was turned off so I dont know if thats the fix for the issue. Shame because the car when it worked look very good but in the end his day was ruined with this issue cropping up.

[shaun m]

soo is it only problem on the "s" / "r" esc then , is the pro problem free ??

And going thro all the booklet they give you with the "r " none of it says 7.5-10.5t on the stock01 software ... it all says its targeted at 4.5-10.5t ..

I think this is the pdf you are talking about
http://www.speedpassion.net/uploadfiles/downloads/20129261811126thSept2012_STOCK1_firmware_instructi ons.pdf


But I believe this is a global guide lines set out for the Stock1 Profile.
The limits of the ESC then must be applied, so if you are using:

The Reventon R the Profile is for 7.5-10.5 Motors
The Reventon Pro the Profile is for 4.5-10.5 Motors

yeah that pdf is the same as i have , and it also says that on my sp booklet , can't find anywhere where it says you cant use a 5.5t on stock software ...

I emailed schumacher , and they suggest turning the lipo cutoff and temp settings off and try that , and never said using that size motor is a problem with the boosted software ...

Maybe 5.5T motor is too close to the ESC's limit.

Ran again last night. Checked temps after every run. Motor was 65 and ESC 55 so no problems so far :D

[Muzzie]

Update - I've ran the SP Reventon -R for 5 months and after the first week of issues, I've not had a problem. A Power Cap is a must if you're running a Savox servo and TIP make sure the ESC Capacitor has got a good soldered joint

OK, this is important.

The Reventon series is NOT related in any way to the GT series. It comes from a different factory and the accessories are NOT compatible.

If you treat a Reventon like a GT, you will have problems. Read the instructions, don't assume.

As far as the BEC goes - the output on the SCR, S and R is 2A, but it shouldn't be a problem with a well designed servo. Savox (and their OEM customers including Spektrum and Orion) are known to cause problems with their excessive power demands.

cheers for your help dave , but i'm using an ace servo , but ive been in touch with the shop i got it off , and they said try and turn the lipo and temp off , tried that and also geared it down even more , changed to the mod software, still no different , still runs hot even on a flat bit of tarmac !! put an old lpf in ( even thou a lpf is only meant to go down to 8.5t for off road ) to eliminate , lipos , motor etc and it was spot on !!

oh and " read the instructions , dont assume " have you read the little mixed up paper they include :eh?: , well thats why i had to search on the internet before it was fitted !!

Sorry chap but I think it's still youe 5.5 motor !
Borrow a 7.5 and try the Rev R again !

This way you can say its the ESC and this is what SP Say Stock1 on a Rev R is max'd out at !!

i appreciate your help , but as i said above ive tried it with the mod software and it still runs hot , but when you go thro the reventon interface thingy , and you have to mark what size motor you have , i did'nt see that using that software and that size motor there was any flashing lights , or anyone saying dont run it ..

and again the man at shuchmacher , did'nt say the motor size with the software was the problem ..
, but the shop i bought it off had said , that it could had been where it was close to the motor limit ..

[tcboy1983]

I have had 2 r's been in tc, buggy and sc with mortors from 17.5t down to 7.5t and never missed a beat only had to turn off lipo as I have old ones with low c rating
As for the software I had to fiddle with the USB files at first with the first ones but new ones work no problem and the wifi unit works great

[shaun m]

tried it today with an 8.5t motor and still getting pretty warm and still on the mod software , its now been sent back to the shop who i bought it from ...

but i'm geussing all the people on here that have had problems with them , are all at fault , and out of the 100's that have been sold , none could have anything wrong with em ??!! ..

[tcboy1983]

Was just saying its a great esc smooth and fast
And u are going to get lots of ppl with faults writing on here
As its the problem page, if u want problems try a nosram/lrp esc
Or orca lol

i know mate , i'm just fed up with people on here, thinking that someones automaticly at fault if they've been ok with em ... they'res going to be a few slip throu the net !!

[knighthawk]

OK ! I must be one of those you mention !

But in my defence all I was trying to say is what is printed on the SP Tech Website

Again all I was trying to say was that although the SP Reventon R has a motor limit of a 5.5 motor, SP updated this to 7.5 with the new V1.8-1.9 Updates when using the Stock1 Profile.

If there is a fault then there's a fault, was just trying to help you eliminate issues due to over spec'ing the equipment.

You stated that the esc was getting to hot, a lower motor would cause a overheating issue

As you have sent this away for check's you will find out when it is returned !

Keep us all informed !

Is the reventon r working now? No more problems? Locking for a new esc to my sv2 and the reventon have a nice price.

+1 - I'm in the same boat (for the same vehicle coincidentally).

Are they on special now because it's a fire sale to get rid of a bad speedo or is it worth US$70?

How have people gone with them over the last month? Anybody running them in hot summer conditions at the moment?

[Col]

I don't have one (I bought the pro and love it) but there are at least 2 at YORCC and both perform faultlessly.

[Thomas B]

Orderd one. Test on thursday.

No mate, from what I've heard these problems were exclusive to the R.
My pro is currently running whatever software came with it, and once I'd actually read the instructions and reversed throttle on my futaba TX, has performed brilliantly since.
It should be noted that (on mine) the stock setting for brakes was 30% which meant no brakes... When set at 100% it will lock up all wheels on any given surface.

Did a test today. Verry good feeling. Soft and a good register. The punch is there when you need it. Verry satisfied so far.

[discothesnake]

I've had no issues with mine so far. Fingers crossed......

[git-r]

I have a SP Rventon R in an Xray t3.

I read through the instructions very carefully and discovered the "note 3" by the 5.5t

I've used it a lot since purchase in Jan with a 13.5t motor and it was fine but recently put a 5.5t motor in and it won't allow full throttle - it does a kind of emergency stop:(

With the car on a stand it does the same thing.. Fine until about 3/4 throttle then cuts then goes again. The orange light flashes too - suggesting esc temp.

This is with all protection turnd off.

Esc temps seem fine.. tested with 3 batteries.. no timing on ecu or motor... 13.5t runs fine :eh?: - can only guess it's not able to push the steady current required by the 5.5t motor..

I've tried all the different options through reventon software and think i have everything up to date..

I read through the instructions very carefully and discovered the "note 3" by the 5.5t rating. it says something about how they only test the motor limit under the following gconditions:

a) The input is a 6 cell Ni-xx battery; b) The ESC is equipped with a fan.


Any ideas??

hobbywing 120a v2 for £100 or reventon pro 140a for the same...??

Hey folks I am ready to blow my brains out..... I have a revention Pro running it previously on a 6.5 and now a 5.5 V3 the speedo was fine for about four weeks however now I am getting 3/4 of a heat and the speedo seems to be going into lamp mode (flat LiPo) I hav.e used other racers batteries to rule it out and it still happens, the setup is fitted to my dex410, my servo is a high speed alturn and the speedo is running the modify2 software.

It's been a very frustrating night as on a number of occasions I have been running quick in my heat

I don't believe I am running the thermal cut off but need to check.

When the car goes into limp mode if the marshal turns the speedo off and on again, its fine.... The motor and esc do not even feel hot.

For what I paid I am somewhat disappointed ! I tried to go on the sp site for help but it re directs me to schumacher


I am sick as a chip, can anyone help ?

Cheers

Did it do it again in the final after you down geared Richie?

I have a SP Rventon R in an Xray t3.

I read through the instructions very carefully and discovered the "note 3" by the 5.5t

I've used it a lot since purchase in Jan with a 13.5t motor and it was fine but recently put a 5.5t motor in and it won't allow full throttle - it does a kind of emergency stop:(

Hi, I'm sure if you check on the website there was something about them changing the rating from 5.5 to 7.5. I reckon their first rating wasnt satisfactory.

I run mine In a 2wd buggy with 7.5 motor and have had no issues. Remember, it's only a 70amp speedo. If you want to run low wind motors you'll probably need to go to the pro version.

I would check the website first tho.

We had this same problem with a Pro and a LRP X20 7.5 however our motor was getting very hot. Reduced timing from 22.5 to 11.25 and all was OK again. Didn't have this problem with a X12 7.5 with the same settings! I have read that this speedo and LRP motors don't play well together. Some are cutting the 2nd wire (don't know which one) to solve the shut down problem. Hope that helps

i think its 2nd from the left as you look at the motor should say few pages back also you can pull the terminal out of the plug dont cut it

also have you turned off your lipo cut off ? as it might be when its drawing large current the esc is askng to much of ur lipos ? this has happened to me alot on different esc

I have had these same issues with a Reventon pro, the car goes into limp mode after 4 mins due to overheat, tried changing the motor from a SP5.5 v3 to a 6.5 with no effect. Took a temp reading from motor and speedo as the car came off the track which were both under 65deg so no issue there. The capacitor on the speedo was around 100deg, changed this for the capacitor bank from a GT2.0 pro and the issue has disappeared (so far). The car now runs for full 5 mins and the capacitor unit was at 45deg. The only thing I cannot understand is how the speedo could sense this overheat on the cap?
I am running v20 firmware but may reinstall the v19 to see what happens
