I'm sure this has been covered before but.... I've been having fits trying 
to come up with the best method for securing servos in a Phil Barnes foam 
core wing. I have used a glue known as PFM, I think it also is known as shoe 
goo. This adhesive, although strong and secure, dimples the top surface of 
the wing. Not sure if its attacking the foam, but it certainly distorts the 
top surface.

Most recently on my new ship I have used silicone, this at first seemed to 
work well, but it didn't hold up and my flap servos are now floating around. 
Makes for an interesting launch when the flaps are both in different 
positions!

On my last Mantis I used the PFM and the servos been secure, I've just lived 
with the depressions in the top surface. I haven't blocked in around the 
servo, perhaps that will be my first next move. If any of you have had good 
repeatable success, or good adhesive suggestions I would appreciate hearing 
about it. I know there's a lot of servos installed out there and there must 
be a better way.

Thanks,
John Hayes
