Anyone know of a smoke system/technique that would work for wing tips? I know there are the ones that spray the oil into the turbine exhaust, and the RC Smoke 'light and go' type.

Contact Eddie, I believe he's figured out how to do it, but don't know if he's actually worked it out yet from theory to reality.

Initially my thoughts are that I don't know how you're gonna deal with the heat in a foam or composite wing []

You may be better off just attaching those 3 dollar RC colored smokers??
