These parts are not compatible with the GRUBLOCK style frame.

If you have ordered V4 Arrma Screw Adjust Motor Mount in only 25mm or 30mm, and decided you want to change your motor size, OR if you want a spare plate to leave on your motor for quicker swapping between motors, this is what you want. 

The Motor Mount Insert is available With or Without the adjuster hardware. The hardware is very easy to interchange between mount plates, and is not included at the base price. Instead of flat out charging $25 per insert, I am giving you the option for a bare plate for $10 less. If you would like to add the hardware (The adjuster plate and the adjuster nut, plus the screw and washer), there is an option for that. 

Did you biff it pretty hard into a curb at 300mph? You might need a replacement motor mount frame to get you back on the road. The replacement frame includes the threaded rod, and locking setscrew and will get you straightened back out. Or maybe you once ordered a motor mount combo with both inserts, and now you have a spare motor mount insert laying around, and have a new build you'd like to use it on! By buying a replacement frame, insert hardware, and a top clamp, you can turn that spare insert into a whole second motor mount. I will get a picture eventually, but for now it is not shown. 

The top clamp does include new screws. Maybe you lost yours, or stripped the screws out and hacked up your old Top Clamp with a Dremmel... and would like to make things nice again. Or maybe you want a spare! Either way, you can get one here. 

PLEASE NOTE, These motor inserts WILL NOT WORK in a factory Arrma motor mount. The PPS Frame WILL NOT WORK with the stock Arrma Motor Mount Inserts. These parts are ONLY for the PPS Motor Mount System.
