RE: Ultra Stick 40 servos
Hay Steve,
I believe I used 1/8th. aircraft grade plywood and cut it to shape. I did this before I installed my rudder and elevator...and I also put a doubler inside the fuse. Its easy before you glue your stab and rudder in and I used he same blind nuts that came with the tail wheel assy. This has never failed me so far...even after a real hard landing. My model was going to come out nose heavy as it was, with the .61 installed. That is why I also placed my rudder and elevator servo's in the tail-for balance, and easy to check here too. I needed a model I could rely on, easy to trim, and fun to fly. You just can't beat an ugly stick, and I don't care who makes it. The hanger 9 issue of the model is very well done, and it's been well used, rode hard, and keeps on flying.
I also ran some thin CA down the inside of my model. Some of the balsa used can be to soft for my liking, so by runnng some CA thin down the sides, it kind of fixes that problem. I would higly suggest to place a 1/4" ply brace under your main landing gear. If you don't...it will come lose in time. I put a brace from the front bulkhead aft of the fuel tank, aft for 3". I used good two hour epoxy to do this, and with this, you will not have a main landing gear attacment issue again. I am hard on my models...I love to do touch and go's, so I beat up my landing gear alot. This model is four years old.
I do place a drop of thin CA glue on control horn attachment hardware. Just a drop on the head and screw end.
Soft Landings Always,
