Well my UF is ready to fly, ran the Cheetah today. The CG ended up at 225mm. I think that is fine for the first flights although I was trying for 230mm. I could only get 88mm of flaps without changing my servo arm geometry so I'll fly it like that too.
I have the main and saddle tanks, there were a few creaking noises during fueling but it is dry so I am good to go. Should get pretty long flights with all that fuel.
I have a gradual pressure loss that I am not too crazy about, about 10 psi per hour gear up or down. The first place I want to check is the festo valve on top of the tank. When the tank is stuck all the way up in the nose the 4mm tubing may be forced to an odd angle. I certainly can't hear it...
The Tamiya Smoke paint was a bit of a disaster. It goes on so thin initially you can't see well how it is laying down. I ended up with some sags and one run. I ended up putting the whole can on in about 4 coats and got it as dark as possible to hide the mess, it looks black now
