Axial Yeti Score Motor/ESC Upgrade - Need Help

[JustMakingTea]

I have bought an Axial Yeti Score and would like to give it more power and speed. I have a 1 year old Losi Baja Rey that I would like to strip the 3800KV 4 Pole 550 Dynamite Fuse Engine and ESC combo and install it on the Yeti score. Does anyone see any problem in doing this and running the stock gearing?

Assuming 3s batteries, I think 3800 is a bit high for the weight of the yeti, but the shorter/smaller score tires (compared to the rock racer) may help keep the heat out of the motor. Watch the motor/esc temps and use a smaller pinion if needed. Expect low speed to cog and overheat if you are not using the optional 2-speed.
