I remember someone saying that 2 speed works best on long high speed tracks, and a single speed works best on shorter, more technical tracks.

I've got a kyosho IGT2 vette that I finally got fed up with the nitro system so I made my own conversion kit. The motor was a 1700kv (don't remember the name but "max" voltage was 3S) of which I had a 28T pinion. I decided to use only the 2nd gear (43T with the clutch shoes locked out) so the drive ratio was 1.54 (43/28). For bats, was using 2 packs in parrallel of 4S 3700mah that are mounted on custom made CF plates on both sides of the frame. For the ESC, was using an old 100A airplane ESC with fan mounted on it. This was basically a quick solution to see if I'd like the electric race car so please don't think I'm absolutely insane with the parts selection above

As to how she drove, well I absolutely LOVED the way she drove on the track (a local race track here in Fairfeild OH). She was definately faster and more fun than she'd been with both the stock .28 and a .21 motor. The problem came when I was trying to see the mah draw of a 15 min race. Around the 12 minute mark, the motor demagged (yes I knew this would eventually happen as the motor was only rated for 3S and I was running 4S).

So now I'm gonna order the proper electronics. I'm liking the 1/8 Mamba Max V3, Neu 1518 1Y 1800kv motor, 4S2P 7400mah bats, and a 30T metal pinion and the 43T 2nd gear.
Using one of the online calculators, this predicts ~ 68mph so not quite the top end I want. So now I'm thinking maybe I should go with 5S and a 28T spur gear which calculates to 79mph.
Anyone using this motor yet?

I believe I've got 100k in both front and rear. I'm gonna change the rear to a lighter oil (prob around 30k) but haven't done it yet until I get the power system where I want it.
As for brakes, I opted not to use motor brake so as to reduce motor load (heat) as much as possible. Ive got a custom front/rear disk brakes that can be independently adjusted when needed.

With a 1700 KV motor, you should be running 5S. See the following chart by Tekno RC

http://www.impaktrc.com/product_info...oducts_id=3076

I myself am running 5S with 1700 KV tekin. Where did you get your metal pinions 28T to 30T.. are they mod 1 pitch?

I am running the MM2650 on 4 and 5s.. 22/46 center diff ratio.. On the 5s im maxing out on the straight around 55-60 mph and have no problem with acceleration.. So to answer an earlier question i dont see an advantage to the 2-speed but i am up to suggestions bc ive got a blackhawk one laying right here that needs some use!

Also has anyone found tires that are faster than Johns BSR 1/8 foams? They are taller in diameter than the ipanemas=+mph and with compound they hook very well..

How is the Kyosho tire?
And the GRP?

The first step!
Out with the stinker!


Some drift touch!


And there was a hole in the body!
Hhmmm!
