In the 5S vid you can really see the punch that thing has

Whats you next modification?
Track is in Hong Kong... which mainly for 1/10 GP...as this indoor facility is very good, I test my 1/8 EP .... until satisfied .. then will go to another track and race with 1/8 GP.....

5S is my final target.. and I am now testing the gear ratio for safe-ride.....

Up-to-date test find-out is... 4S with 2350kv or above.. torque is not enough, some kind of mis-matching.... motor very very hot...

and 5S with Losi 2100kv gives a good balance between top speed and torque.... and now carefully lowering the gear ratio.....under motor temperature around 65 deg cel....

i just got a nice used 960 08' with a ton of spare and decided to go either 4s or 5s and am not sure. have the speedpassion conversion and have a question. what about 2wd - ie.. remove the side belt and front oneway? less strain on the electronics, lighter and can mount the battery(ies) perpendicular to the chassis. i am thinking like a large 1/12th scale with an infinitely more adjustable front end. with 4s power it could be lighter and still handle well. i race 1/12th and they eat up touring cars. i admit the set-up would be crucial to making it handle well....bnut isn't that half the fun it would also be a cheaper set-up to run as it would less strain on everything and won't need those big packs. lmk what you think

I am also using the speedpassion kit... with only one 2nd gear... I found motor selection is very important... currently 2100kv x 5S Lipo... still safe-ride...

I estimate... 6S 2100kv with 45S/19P would give the same speed as 1/8 GP...

You got it sam! 6S with a 2100Kv. gives the same power as a quick gas 1/8th. I run a 2nd gear combo of 44S/20P (Pinions courtesy of Monster Mike) as this is what I run in my car.

I'm currently looking at changing my battery configuration to a 1200mAh 6S2P config. I believe I can make this all fit under the radio tray and have the pack slide out from one side. Now I just need to find some money

Use a MMM and a high quality motor around the 2000-2200 KV. range.

I use a NEU in my car. It's all I've ever had and has never given any trouble.

i have two 3s packs rated at 25c/30-35c and 2500 mah, will run in series for a 6s set-up. can these packs handle the amp draw? also what is a quick way to estimate amp draw on a system?

Here's my new video.

***CLICK***

P.S. Click the HQ button on the bottom of the youtube viewer window for a superior quality picture, it deals with the motion much better.

I signed up here because of you guys and all these information....I can't wait to get my SERPENT going with the right batteries, speedo and motor and run with the NITRO 1/8th.....been racing the 1/8th for 3-4 years but I have no doubt to believe ELECTRIC will soon take over the 1/8th scene...keep up the good work and keep posting new info,

So - last weekend i could finish my conversion ... 1800kv on 5s Fepo is not soooo fast as i hoped it will be... but also with this performance i need to replace a rear hub

i only have a 2600kv motor as replacement - this would be like 6s fepo on 2000kv ... but the 1800kv motor already got hot at the weekend session ( most of the time drifting )

@CountryChick: are you running 6s2p fepo now?
