You could probably buy a fuse for the ME-109 from Top Flite as a spare part and have a cheap plane, and possibly the others too. Since you have two of the same for the Kwik Flies I'd be tempted to go the franken-plane route with them and do something bizarre like a canard bipe pusher or something... but that's just me. Hmmm that'd look look a bit like a Star Wars X Wing fighter that someone'd stood on.
