Bought the kit, and created a Frankenstein's monster, sort of. The electronics are from the RTR B4.1, which is a brushless Reedy 3300kv motor (540 can) and the XP SC450-BL Brushless ESC. I found out the Reedy 3300kv motor isn't enough for the 4x4. Either that or my gearing is way the hell off. My truck was thermalling off after 3-4 laps. No temp sensor, but it was super hot to the touch, both the motor and ESC.

For a tiny track, maybe 65x30, would this combo be alright? The fast laps are low 10's. I'm not trying to break the bank, but still would like something halfway decent. Thanks.
