Minnflyer's right. No crime to keep the rubber bands.

I have seen exactly 4 high wing trainers converted to bolts - two Aerostars, one Falcon something, and an Eagle II. Each one had aileron servo travel interference, with the wood bosses for the bolts. The wing would set in place and bolt down okay, but the new wood bosses would interfere with servo travel.

Three of the planes were lost due to wing mounting failure. Two had bolts pull out of the new bosses. One had the new front dowel capture feature pull out.

When students ask me about changing to bolt-on, I advise them to just keep on flying the trainer as is, and apply their building efforts to a plane designed with bolt-on wings.

Best wishes,
