db01 speed noobie questions

frogjim · #1 10-08-2010

Hi all

I have got my first rc car, since wanting one from when i was about 13(34 now), I have the tamiya durga. I have build it up and after lots of mistakes i think ive got it all sorted..

I brought a novak havoc 1s esc and 13.5t combo off ebay (not knowing at the time wat the 1s bit meant). So after lots of messing about i have in the car and am using a 1s lipo battery(the 1s bit).

My question is what sorta top speed would i expect from this package and also have i brought totally the wrong type pf motor/esc combo for a 4wd?

I have used the 23 pinion that came in the box

Any help would be great?
Thanks
Jim

yes you bought the wrong speed control. You happened to buy one of the only 1 cell lipo speed controls that are available. You need a esc that is capable of 2s lipos.

regarding speed, it depends on your motor, but a 13.5 is not very fast. The durga is not the best car for speed, as the diffs dont hold up very well without upgrades ie. 1 piece outdrives, carbide diff balls, slipper clutch. Would have been better starting out with the db01r but even then you would still need the outdrives.

Have to confess I've never heard of a 1s ESC and im not sure it's suited to the Durga or what exactly it's meant for.

"This ESC is ideal for beginners and local, club-level racers, and will excel in the Oval, World GT and 12-Scale racing segments."

i have the slipper clutch installed and a few other hop ups..
i did wonder why the motor and esc sounded such a bargin lol...get wat you pay for then...

Maybe the best solution is to sell the 1s lipo battery i had to buy and the motor and esc on ebay and get something else...Had a lot of hassle getting it all to work and now it sounds like ive brought some junk...hey live and learn...

thanks guys...What would be a good esc/motor combo for this car? does the fact a car is 2wd or 4wd make a difference in motor choice?

thanks for your replies!

There are lots and lots of suitable ESCs out there for 4wd.

Look for a "sensored" system. For motors, a 7.5 will be amply fast in a 4wd. You will need a different pinion gear, use the smaller one that comes in the kit to start with.

Also make sure it is suitable for 2s Lipo (7.4V), and that the motor is 540 sized (for 1/10th scale). There are a few systems out there with bigger motors for 1/8th scale and trucks, wouldn't want you buying the wrong system again!

You'll then need a 2s Lipo stick pack for cars.

From Novak's range (for example), they do a "normal" Havoc that will suit, and their own range of motors. A lot of people on this board (including me) use the Speed Passion speed controllers and motors (or rebadged versions from Hobbywing and Much-More).

For the battery pack, the Durga was designed for NiMH stick packs, so not ever LiPo will be a tidy fit and might need a little chassis modification. A good place to start is the BRCA list of legal racing LiPos - http://www.brca.org/BRCA/elecboard/n...20v2%20pdf.pdf, although if you know you won't be racing, there are lots of cheaper LiPo packs around that I can't really comment on the quality of. There are also a couple of stick-packs with rounded edges which will fit very neatly in Tamiya cars.

I recommend popping the Havoc and motor back on Ebay - there's nothing wrong with them, but they were designed for 12th scale or class racing touring cars, etc. Someone will buy them back, hopefully, what you paid for them.

Given the amount drag involved in driving an off-road, you need a stronger speedo and a more powerful motor.

DB01 is a little fragile for the big stuff the pro guys put in their cars, but not so bad to get rid. If you throw a 5.5 or 6.5 into the DB01 it will rattle through the diffs/gearboxes pretty quickly.

Firstly, go looking for a good speedo. I run a Castle MMP, but GM, Speed Passion, Tekin, etc are all equal alternatives. It'll depend on your budget, but the more you invest now, means longer life span, less problems and very few compatibility issues or limits. Buy "as new" as you can afford.

Then start with 9.5 or 8.5T motor, or if you are running indoors, consider a 2nd hand 10.5T from a TC driver - you'll get them cheap 2nd hand and they'll give you enough power to get around a track. You might be slower down the straights, but it'll be more controllable and give you time to get used to the speed. I've always said only put a faster motor in, when you stop hitting the corners!

Then when you are ready to go faster, sell the 10.5 and move up the motors slowly and at your own pace.

I still swap between 6.5, 8.5 and 10.5 in my 511, depending on how useless I am that day! Whatever gets me round the track with the most consistent lap times...

I wouldn't worry about this statement, as you have the slipper it'll protect the transmission but if you just add the 501 diff halves in the rear (or the cheaper 3 racing version) then you should have no problems regardless of motor.
