I'm also interested in JJ's take on using any product that contains
silicone on gliders. *I've read some things that have made me very
paranoid about what touches my glider.

Its probably best to staw away from products that contain silicones,
but any repair involves a thorough sanding all around the repaired
area. I have never had any adhesion problems and that includes
glassing right up against fittings that were soaked in lubricants. I
grind until all the damage is removed and until I can no longer see
any lubricant in the structure, then scrub it down with acetone, dry
it well and start laying in the new material. Don't really see how
anything can survive the above to result in a problem.

On a completely unrelated subject, I'm getting back into R/
C.....................when I last flew we were driving a Babcock
escapement with a 3v transistor tone radio. WOW, have things changed,
but I have a couple of questions. How does a 'brush-less' electric
motor work and my radio says it is FM, but is crystal controlled, how
does that work?
Thanks and sorry for the unrelated questions, but I am flying an RC
Easy-Glider,
JJ
