MGM compro + feigao 6s + TC4

[MikeyLikesItSI]

Hey guys, even though this is my first post, i've been lurking around for some time now.

I purchased an MGM Compro 8012 and feigao 6s from mike a month or so ago. I put this setup in a 1/12th scale pan car The thing was definitly a freakin rocket. 65+ MPH on 6 cells. i used a 20 tooth 48p pinion and a 75 tooth spur. Overall final ratio was 3.75:1.

I reprogramed the ESC so it would accelerate over 1 second, otherwise it would just spin out under hard acceleration. Well, after going through 2 sets of tires in only 4 or 5 battery packs, i decided the car isn't for me. Moving on......

I purchased and just assembled a brand new RC10TC4. Using the same 20 tooth pinion, and the stock 72 tooth spur gives a 3.6:1 ratio. The differentials, front and rear, are 2.5:1, for an over all ratio of 9:1. Now, given the much higher ratio, i figured it would obviously not reach the same speeds as the 1/12th car, but should rev fast with lots of torque. I reprogrammed it to accelerate quicker (now having the advantage of four wheel drive as well). Still using 6 cells. Well, it takes 100 feet or more for the car to reach top speed. the thing is an absolute dog out of the hole. It takes forever to come up to speed. I tried several different programming settings. After about 5 minutes, the motor was only luke warm, the controller wasn't much warmer then that, and the battery pack was quite cool. Shouldn't this thing be ripping up some asphualt? any idea's?

My rc10t with the novak 4300 brushless system has close to the same ratio, and wheelies off the line and ROOSTS like mad in dirt!

Sorry for the long post :o

Thanks guys!
