Dick,
great article,

on a side note, your not planning on using CA hinges in your new stunter are you? IMHO, they introduce a LOT of friction to the controls, which on an RC plane that has a servo to recenter the surface, on our creations, it really can make life unpleasant for those critical little moments when line tension gets a bit soft!

I think it's more spring-back than friction.

Not that this makes much of a difference when the lines go slack and the aircraft suddenly has a mind of it's own...

Here's one of the best ways to install pinned hinges, using CA glue (thin) by ***John Miller***. Almost cannot fail or have a problem. It's a .txt file...Wordpad or about anything in that line should open it.

I prefer having a removeable hinge pin (one long pin for each flap, each elevator, and the rudder, if hinged), so I'd skip the Vaseline step and remove the pins first. It's very important to get the second half to align with the first half, tho! Wax or oil the long pin, and glue with the pin installed, even if it's a raw hunk of piano wire. But this is all relatively easy, and a fine use for thin CA. Thin CA is a great way to toughen up a punky piece of light balsa, like the tips, to toughen them against hanger rash.  Steve
