I almost exclusively scratch build my own designs. The squishy idea that was pioneered by tufflight has finally caught on by many others after all these years as has the flying wing.

If you follow their directions properly there should be no issues as they have probably seen them all.

I do take many of my idea inspiration from tufflight like the breakaway engine mount, fuel tank/launch handle and removable vertical fins.

My newest batch has leading edges made from boogie board foam or epp. So far they have held up exceptionally well in midairs without destroying the other planes that I have hit.
