RE: ( U Can Do 3D ) is this a good plane to own?
Beef up the tail so you don't rip it off.
Use 4-40 rods for the surfaces, becasue the stock ones bend up like crazy and the plane won't trim.
AND, with a Jett Muffler on that 91 it performs much better than the stock one. I found the pull out a little sluggish, however with the Jett it was much much better.
