OK, I'm really hoping that I'm done with the microballoons until the next airplane. . .

I suspected that the control surfaces had absorbed alot of water during the wet sanding process so to make sure I went to Hobby Lobby and picked up a bag of silica dessicant. I dumped the whole bag of dessicant into a clear garbage bag ,added the control surfaces then sealed it all up with a zip-tie. I then left the bag out in the sun all day in the driveway. The total weight of the control surfaces was 199 grams at 8am, and then 194 grams at 7pm. I think it is safe to say I got all of the water out.

I then spent the day working on the canopy, finding a place for the remote needle valve, and fitting the pipe support. A couple more test fittings of all the pieces / parts and I should be ready for primer. . . Maybe. . .
