Minnflter:
Not really true. The tape is just like an extension of the wing tip (only vertical, thus lowering the center of gravity). You can use any width tape and it will work, because it is where you pick up the tape that counts. Lifting by the wingtips by the fingers does work, but
the trouble is it is like an uncontrollable tetertotter, so using the tape makes it soooo much easier. Taking the paint off with the tape
is certainly a consideration. I used this on a film covering so no problem, and also used masking tape, so shouldn't be a problem for mose paints (but could be, I don't know). Once you try it, you will be surprised how much easier the balancing becomes.
Happy flying.
