RE: Simple question
Just a note from a former Calmato flyer. I don't think there is necessarily a problem with that plane, but my wing fell off in a turn...the fuselage failed and both wing bolts and a piece of the front former came with it. Just try to reinforce the areas where the wing attaches to the fuse and check it before you fly, every time. It was a great flying trainer and could be quite aerobatic. It has a semi symmetrical wing, not a flat bottom, so it can be a bit squirrelly for a trainer.
Have Fun!!
