It will be tough if you use a heavy battery pack: any pack over 220grams will make you overweight. Thunderpower 3300 65C packs are 205g to 208g, and are good to try but the side to side balance will be affected. My Fttc4 is around 1390grams with these packs, but my electronics are heavy. I can loose another 70grams by switching to the tekin Rs/spektrum/Savox 1251 combo but that's too expensive...
Anyway, I have found that it is best to never run AE rubber sealed Bearings on the tc4 axles because of the increase braking effect of rubber while cornering. It is best to run teflon sealed Bearings on the axles or ceramic Bearings....
