Can you give me some information about 1/12 modified class? What motors do you use? What rollout, timing and setup in esc.
In last weekend i had some problems with my 1/12. I used 4.5 Vortex motor from my 1/10 Touring car. I used LRP 2007 sphere. Setup from 2,1,0,0 to 2,6,0,0. I changed rollout from 27 to 35mm. I didn't change timing and used factory setup. I had problems with speed, runtime and punch. My car was slower then cars with brushed motors (10x2, 9x2). Do i need some special edition brushless motor prepared for 4 cell? I use new ib4200 batteries.
