That multiplex motor is big isn't it, I thought they were the same size as the mega!!

Well this post got me thinking and I dropped a MM in. Then I was like well I'm working on it, can I make a 2s 1100mah A123 fit and sure enough it does, with a slight trim of the chassis. Still not the smoothest startup with high timming and low start power. Broke another knuckle and stripped the servo gears not sure if I have spare gears or not?

This was also my first drive on some new tires. I bought the 12mm adaptors and picked up some SNR rally tires, they are about 10mm taller than the stock pin tires and the same width. They are quite heavy compared to the stock tires and rims though so that might be part of the rough start.

A123's will kick butt though I have been charging the 1100mah cells at 8.8amps and they stay cool at 10a they were getting warm. So charge times will be very short and I think these 2s 1100mah packs are only $20!
