What runtimes are you all getting then...?

DaveG28 · #1 25-04-2009

Just wondered what runtimes everyone is getting, if anyone could let me know, along with what motor/cells your using?

electric · #2 26-04-2009

about 20minutes on some ftx 5000mah 7.4V 20C packs in a Losi 8B with mamba monster esc, medusa motor and rc monster motor mount.

i have some zippy-R 14.8v 4500mah 21/35C's on the way and would imagine they would give a similar run time...

I'm getting about 12 minutes driving hard. This is with Flightpower 4S 4350mAh Lipos in a Hyper 9E. Motor: Medusa Research 2000kV motor with a Castle Creations Monster Mamba.

Soon I'm looking at getting some 5S ~4500mAh Lipos to get that run time to about 15 - 16 minutes.

Managed a 15 minute nitro final using a FlightPower 4S 4500mAh 30C and a Neu 1512 2600kV motor.

hi, i got them off the french ebay site. they are a bit long for my battery trays (about 3cm too long) so i may sell them as i have to strap them to the top which is neither safe or good for low COG.
if you are interested PM me an offer (i have 2 4s packs)

EDIT: i forgot to say these zippy-r lipos are far better than the other zippy lipos and are reported to be made of enerland cells in korea...

i had a simlar prob with the 14 volt trackpower lipos at neo but found that i could turn the cels on there side and run them diagonal across the tray. this ment they still ran on the chassis line although i did have to cable tie them in lol. now got to try and find some 10k mha lipos so i can do a 30 min final :P as want to kick some nitro ass

I did a 15 min final at a border counties league last week and pulled in for a lipo change at 10 mins just in case (was grass track so didnt want to risk it). Pit team did a great job of swapping it in 23 seconds lol !!! and still managed to win by a lap

Haha yeah that pitstop rocked!!

what mah and kv were you running by the way? Had chance to see what was left in that first lipo by the way?

HarlowS · #11 01-05-2009

I was running a Tekin 2650kv motor and they were 3700mah packs in the final. havent discharged them yet so not sure. If i was more prepared i would of ran the 5000's

But hey ho

DaveG28 · #12 01-05-2009

Any tips on where to get batteries? Hoping to race in may but only have one pack!

HarlowS · #13 01-05-2009

Not really, i picked up a couple of 3700's from the airplane section on ebay, apart from that there are some good value packs from hong kong at about £40, they may be only 20C rated but the 3700's that i run are 20/22C and the car wasnt slow

Marvin · #14 01-05-2009

I would look at Flightpower packs (either eBay or almost all model shops that sell Heli's/Planes) as they are fantastic quality and you can get them in practically any Voltage, Capacity or Size. Otherwise 2 Trakpowers in series or any of the car race packs really (Orion, LRP/Nosram, Core RC etc).

The Overlander Tornado packs are also worth a look; good quality cells, reliably rated and in various sizes. They tend to be slightly cheaper than Flightpowers though, but are still very popular in Helis, so many places sell these too.

Are thunderpower any good?

Marvin · #17 01-05-2009

Yes, Thunderpower are also good. They are made from very similar cells (from the same manufacturer) as the Flightpowers. PolyQuests are also worth a look.
