In my AWD I run a Kyosho AWD X-Speed motor but I have replaced the can for a ball bearing can !! I of cause also have BB’s throughout the car !! I run alloy spacer/motor holding plates and an alloy motor cover which of cause help with heat dispersion !!
I run 17/29 gearing for smaller tracks (upto 2 car garage space) and 19/29 for slightly larger tracks !! This ratios seem sweet for some fairly fast racing !!! After a race which is a full set of Sanyo 1000mAh batteries my motor is just slightly warm…
I sometimes run the 19/29 gearing on the smaller track for a little extra speed but it can get a “little” laggy coming out of the tight hair pin !!!
But yeah it is really a track, motor and skill dependent thing !!! 😀
