need some help from an experience TC3er! I have been racing 1/10 and `1/8 scale trucks for some time and am new to on road. i picked up 2 TC3's and one of the things i am puzzled by is how to set the gear mesh properly. I have the cam attached to the motor then i push it down in the slot and then put the combo heatsink motor hold on and screw it down. Do you adjust the mesh by rotating the cam slightly to where you want it then put the heatsink on - i was thinking that when you tighten this down it moves the cam??

Thanks

Andy
