Alright! I received the RCPD motor mount today. The top plate, not surprisingly, fits perfectly onto this mount. I also got the RC-Monster battery tray and will wait to permanently mount it until I get the motor and remainder of the electronics. I hope to balance the car out left to right and front to back the best as I can. If you guys have tips on how to balance weight please let me know. Here are some more pics . . .
