You do nice work! If I could make a few comments/suggestions...... Be carefull on the type of hinge used in the tail. I lost my first ULT cause I used the round Robart hinges on the rudder. These did not leave enough wood, and I broke the stab just above the fuse. I was doing a flat turn about 25' up at the time. It snapped when the fin broke and splattered. Second... while in this stage take a small T pin and put holes in the stringers of the rudder and elev halves. Do this from one end to the other. When you go to cover this big thin flat surface, these holes will let the hot air out of the covering and make it much easier. Third... Take the rear turtle deck out now. First use it as a template and cut the covering out for it about 3/8'' bigger than the deck. Then wet the deck and roll it up a little at a time with some tape. After you wet it and roll it tighter 4-5 times, you should have the outer edges touching and taped together. Do this a little at a time. You can split this ply at the back where it meets the front of the fin if you go to fast. I'm sure there is a 4th and 5th they just aren't coming to me right now.
Keep up the good work, david
Thank you!!
I plan to use the dubro pinned hinge and will pin/epoxy them to keep them in. They are relatively light and strong and should stand up to a few years of abuse. I will probably use more than the plan shows for added strength. The plan only shows 3 on the rudder. Kinda crazy if u ask me. 3 per elevator should be ok. I will go with 4 per aileron.
Good point on the turtle deck covering idea. I will probably make a template of it tho as I'm still undecided on the covering scheme.
