RE: rubber bands for wing hold
Lopflyer..
I hate to admit it, but I did the exact same thing all those years ago when I first started in the hobby.. ( Early 80's.)
Later on I also modified my SIG Kadet MKII with wing hold down bolts.. although when I crashed, I usually took a Fuse side or two with the wing... got good at reparing the sides of the Fuse tho..
