Motor mount made too short

I left a thread on the rcuniverse forum about the motor mount. After looking over the new plane the motor was off to the side. Took the cowl, engine mount and motor off and found out the one leg of the mount was about 2.5mm short (must have been the end of the day and they ran short of steel)... I can't fly without a motor mount...thanks

I suspect it is on purpose to produce the necessary right thrust angle...

The motor is so far to the right that the prop spinner crushed into the cowl.
If it's left like it is, it would fly in a circle and I would not need a rudder.

I'm wrong, you are right about the motor angle , I found a spacer that must have dropped out of it's bag while I unpacked the plane. It now clears the front motor cowl. Thanks for setting me straight.

Is this the FMS SkyTrainer in disguise? Either way, with the spacer, or without you want to make sure that at the end of the day the motor is at 1 to 2 degrees to the right and 1 to 2 degrees down. In my FMS SkyTrainer you achieved it by connecting the motor mount straight against the firewall and putting the spacer between the mount and the firewall at the right upper corner when looking from the nose (or the pilot's upper left). It is not the end of the world if you don't do any of it, but then you would need to add quite a bit of trim in the air to account for the luck of right and down thrust angle. Good luck...
