RE: help needed patching a hole in a wing
hard to tell for sure from the pic... tht's just a hole in covering with no sheet balsa damaged?
If so... Clean the covering with Windex or similar amonia based glass cleaner. Then you trim off the damaged covering to make it into a hole. cut a patch a little oversize for the hole. and iron the edges of the patch down, then shrink the patch.
If there is balsa damage also... you hcae to open it up and patch the wood. (which may be as easy as piecing it together and a few drops of cS... or some cutting and splicing in new wood.)
A normal household iron works. I used a travel iron for covering models for over 25 years. (pushing 30... I still use the travel iron more than the MonoKote iron.)

Just lay a patch of UC over the area about 1/2" larger than the hole.
Cut the corners at a 45 degree angle (or round them off) just so you don't have any sharp corners (They can lift).
A regular iron will work, start with the lowest setting until it starts to stick.
Do the corners first, keeping it fairly staright and wrinkle free. Then work the iron from one end to the other back and forth.
Increase the heat and repeat until all of the wrinkles are out.
The bad news is, you'll lose some of your decal, but you could always try to touch that up later with a little paint (or blue covering)
