Sounds great ,I think up to the 46gt they say stock drive train is OK. Regularly fly mine 10 fi in air over 20 foot gap for 45 minutes. Never broke anything. Wore out drive shafts . Run outerwear products on shocks and engine .after 4 years air filter still looked brand new. All I have done is put 1 million diff oil in all 3 diffs, bartalone pipe and a velocity stack/air filter from ddm.Still runs super strong . Oh I did get brake set from Detroit rc too because the pads wore out.....Been awhile, I did break a pinion...rock... went up I think a tooth or 2 to gain speed,detroit part i believe .Remembering more , did put taylor braces in too , that's it........no 30 degree north body,getting old and forgetful, the losi body is on my 2nd raminator...duhhhh.
