Joe and everyone,
Getting closer on the UCD 60.
Unfortunatley I'm still having radio issues so it will be another week or two until first flight.
I have a couple more questions if I may.
Back when I was active in the hobby we probably did things a lot harder than now.
I have two questions.
We used to take shrink wrap and put it on the wing saddle area of the wing.
Then we would take RTV and apply it to the wing saddle.
Then bolt the wing and fuse together and let the RTV cure.
After removing the wing you could trim the excess RTV and have a perfect seal of the two.
Is this still recommended.
The second thing was when I would use vinyl adhesive tape to seal the control surfaces I would place the tape on the bottom surface of the wing, stab, etc. I would have the surface deflected up as far up as was comfortable. I would then sprinkle talcum powder thru the gap on the top of the surface so as to keep the tape from sticking where I didn't need it too.
Any suggestions for a better way?
Thanks!

I use 1/8" x 3/8" single-sided foam tape

For hinge gap seals, you can use clear Monokote. Cut a strip as wide as you need 1/2" or 3/4 " and as long as needed. Iron the strip on the bottom of the wing or stab 1/4", bend the flying surface up iron on back of TE in gap then onto flying surface LE then onto bottom of flying surface. When finished it will look like a upside down V with two flat legs. Do that to all hinge gaps.
Hope this helps
