I just got a BP21 that I plan to use in a GWS Zero & GWS TM400, and my understanding was that the gray plastic mount is a direct swap for any GWS stick mount. The plastic mount that came with it does look like it will fit, but I can't figure out how to mount the motor to the plastic mount. The plastic has two screw tabs, but they don't line up with any of the three holes in the aluminum back plate of the motor. I can get one to line up, but then the motor is off center.[sm=angry.gif] I figured I'd just center the motor and drill three new holes in the plastic, but the holes in the aluminum overlap the edge of the plastic when the motor is centered, so you can't drill three holes.[:@] HELP!!! What am I missing?[sm=confused.gif]


thks, scott

Ok, sorry, after a little more searching, I found a photo that shows the motor mounted on the stick, and I didn't realize it goes ABOVE where you would normally put in an inrunner. So when I play around with it, it looks like a screw goes through the hole at the end of the square receiver for the stick, and the two others line up on the circumferance of the ring housing. So I guess you just drill two holes in the plastic for them, yes?

thks again, scott

yup that's right, align the motor like you said then drill 2 holes for the other screws and enjoy. The idea is that the prop shaft will be in the same location as it would have been had it been a standard geared setup so you are not changing any thing.

Or get one of these :
