I took a 1/2" square piece of balsa, carved one end to slide into the fuse about an inch, carved the other end to slide in the motor mount with roughly 3 deg down and 3 deg right angle, and put one bolt in each end. This really helps how the plane flies although I still have to adjust my trim a little bit if using full throttle. I have nose dived into the ground with this motor mount and it just broke away, kind of like a crumple zone on a car, I didn't even bend the shaft. I set my cg so that the nose is pointed slightly down with my fingers 4 1/8" back from the leading edge under the wing. I don't like the idea of bending the fuse, even if it doesn't crease if you ever hit something head on hard it will be prone to continue bending in the direction it is already bent. It took me about 30 min to make the first one of these mounts and about 15 min to make the 2nd. This isn't my mod I picked it up from reading this site at it was really helpful to me. You might want to give it a try.
