Holding the wing on
The plane I'm building has two steel screws to old the back of the wing on. The front is held in with a piece that slots into a hole.
Do you prefer steel screws or nylon for a 60 size plane?

RE: Holding the wing on
I use both. In my experience 1/4 20 nylon bolts almost never break without doing damage to the air frame. On trick is to leave some space between the surface and the hole plate.

That has been my experience also. Nylon Bolts don't ever seem to break without doing major airframe damage first. Might as well use steel screws (#10).

RE: Holding the wing on
If the bolt doesn't break, you are using a larger bolt than needed. This is a common misconception. If you want the wing to shear off in a crash, like on a trainer, the use of 2 one quarter inch bolts are as efective as steel bolts. Most .40 sized trainers will do just fine with a single 10-23 nylon bolt. You will want to check it after every rough landing, but it will shear if you use a wing tip as part of your landing gear. This size bolt has plenty of tensile strength to keep the wing on while in flight. I flew shoulder wing quickie 500s with Fox .40s with one 10-32 and never lost a wing in flight. One 1/4-20 nylon bolt holds the wing on my .60 size sport airplanes.
Good luck

Red,
can you send me the plans for that?

No, but I can give you the formula.
The probablity of crashing your model is inversely proportional to the number of flyable models you have in the hangar.
