Status: offline 		Sean: go to this url and download the instructions (Adobe) for this plane. I think it shows a good picture of how aileron torque rods are normally done. Basically, the torque rods and their bearing tubes are flush against the TE of the wing. Then, a piece that is the equivalent of the ailerons is grooved out in the front to fit over the torque rods, and glued in place. There is also a hole cut into the bottom of the grooved piece where the horn ends stick out.

Status: offline 		Thanks bob,
I understand how to do them this way. I have always done torque rods this way. What is making this hard it the fact the ailerons don't set in the TE. There is no place to hide or encase the torque rod. I was trying to figure out how to do it if I didn't have the extra TE to set it in. I may have to re-evaluate and either do the bellcranks or two servo method. I can do a hidden belcrank pretty easy.

Thanks for the link! Weather has taken a serious turn here! Maybe snow this weekend! So I feel better about still building!

Just got back from flying mine in St. Louis. (Visiting daughter & family) I think I'm finally getting the hang of the Cline fuel system.

Very windy and kinda cold (45 deg), but the stick really handles it well, especially with the quad flaps.

The ground handling was so poor on paved runways with the tail dragger setup, that I've decided to switch mine over to tricycle. I've ordered one of those Robart 654 steerable nosewheel assemblies.

Status: offline 		The Stick doesn’t really lend its self to a tail wheel very well because of the low stab and the one piece elevator. I’m sure if Phil thought it should have been a tail dragger he would have designed it with a tail wheel. Many of his other designs were tail draggers. One of the many things I love about the Stick is the way you can drag it in and land super nose high and gently touch down on the mains and then slowly rotate down on the nose gear or is some cases stay on the mains and add a little power and lift off again. I always had to epoxy a wire along the bottom of the sub fin to keep it from being ground away on tail low landings.

Status: offline 		I'm with ya 8178. That was the greatest thing with my sweet stick. (same thing a bit smaller). I didn't get as much building done today as I hoped. I have all the false ribs in and all the secondary spars. Now comes the thinking part. I'm not giving up on the torque rods yet. I'm going to fit the wing to the fuselage now and see how it all works out. Perhaps I can add about 1/2" to the trailing edge to cover the torque rods. I woke up last night about 2:00 AM with a new idea! I'll have to fit the wing and see how it all ties to the fuselage.

I think your really gonna like the trike setup Bob. Let me know how she turns out.

I kind of reached the same conclusion independently. The stab is so low that the propwash doesn't seem to get under it, and the tail never really lifts on TO. Makes it real squirrely, even on grass.

Status: offline 		Well, the first dissapointment. I worked really hard making sure everything is straight. The wing really looked good after I unpinned it and lifted it off the bench. I let is sit flat on the bench since the last time I worked on it. After I unpinned it I glued in the top front secondary spar, then the false ribs, then the lower front secondary spar. I took another look this morning to admire how fine a job I was doing and found the TE has twisted. The LE and the main spars are nice and straight, but the TE has warped up at both tips. Probably about 1/8". It looks like "washout".

How or why did this happen? I've pinned everything back down and I'm going to glue the rear sheeting on the TE and then put in all the shear webbing between the spars. Then the tips and everything while it's pinned down straight. I'm hoping that the shear webbing and trailing edge with pull it back and hold it straight. I'm not sure how or why this happened? Any ideas on how to keep it from happening the next time? Maybe I did something dumb that I overlooked..........

Basically you have to glue on every single piece that you can before you take it off the board. Stub ribs, TE sheeting, any remaining spars, etc., etc. All the pieces work together to help it hold it's shape. Leave some of them out, and you're liable to get bit. (I learned this one the hard way, too.)

Status: offline 		I found what I've been looking for. Strip Ailerons I knew there was something. I'll try these out. There wouldn't be any need to cover them up with extra "TE". I should be able to put it right into the TE like a hinge.

Gonna lift the wing up later on. I've been praying that she will stay straight! I've gotten everything glued on that I can. Really think the webbing will help hold it. I must have "pulled" it somehow inserting the fasle ribs.........

Gonna eat Easter Dinner and pray some more then lift her up from the board....

Status: offline 		Well, the twist seems to have come out. There is a "little bit". Probably about 1/32" on each side now. It is exactly the same on both sides. Very strange. If it doesnt twist any more I can easily fix it during covering. I'm not even sure it's enough to worry about.

I sheeted the bottome of the wing and I have my dowel supports in, and servo mounting ready. I just need to order some parts from Tower today for the torque rods and I'll be ready to roll! I'll try to post up some new pictures.
