Hey i have a problem. To get the motor at the correct angle, the adjustment screw has to stick out a certain amount. The problem is that for it to be in the center, the screw will hit my prop. Any solutions?

I had the same problem and it seemed the screws were so tight going into the plastic mount they end up stripping before you get them all the way in. I had thought they were threaded in all the way but no, I still had a ways to go. The soft metal slotted screws are the devil! Toss them out and use some hex screws from a Nitro Savage screw kit. They are the correct size and fit perfectly. I ended up using this motor mount

It comes with the optional Socket head screws and they are not the soft metal.

Spinner is on good and tight and there is still lots of clearance from those screw heads.

If ya take some Vaseline and lightly coat the first two or three threads...they can be tightened real easy...I did that with all my Multiplex Motor Mounts..Makes it a breeze to change out power systems as well......Billy

Looking back, I think it might be a good idea to 'pre fit' the screws before you actually glue the mount to the plane. I found it took quite a bit of pressure on the screws to get them to screw forward, I'm sure that without enough pressure you simply cross thread the blind hole. Once you've 'tapped' the holes it'll be easier to screw the motor mount plate to the actual mount.

I've used the supplied screws, socket head and bolt head. Personally I prefer the bolt head and to use a small socket, less likely to slip or chew the head, which I have done with both the supplied screws and socket head screws. Pozi/Phillips head screws would be better, flat head always seem to slip and cause the chewing and small allen keys tend to wear very easily too.
