Which trainer?
Fastshy,
Sorry you had such a rough time with your SPADS. There are other alternatives to the downspout fuse. If you lok you can make a coro fuse or use Aluminum railing for the fuse. Personnaly I don't like the donwspout too much either (but for control surface conectors) I use mostly the other two and have found them to be very tough and very light. Check out the PQHOR profile funfly, might be a fun play-around-with plane for you.
