Co Fly

Does any one know of a resource to help me trim my planes before first flight, directions- pictures-angles.

I recently built a Smooth -E from mountain models, and have basically wrecked the fuselage trying to trim it out right. I have tried eyeballing it, but this hasn't helped, what I thought was good on the rudder turned out to be to much lift, and the plane always wanted to go inverted shortly after take off I corrected for the roll only to have it role the other way. I am having so much trouble getting this thing to fly long enough to even get my fingers on the trim buttons?

I got one decent flights out of this plane, I was maxed out on my right and doun trims, so I readjusted the control rods, recentered the trim and tried to fly! It flew even worse!!!! I will be building a new fuselage, and want to get this one right. I would really appreciate any advice. Thanks

Make sure that the plane is properly balanced at the C.G. and also laterally balanced from side to side. that makes a big differance on these smaller planes. hope this helps some.

Check the angle of the tail and wing also. The wing should have a positive angle compared to the tail. Im not sure what angle or how to do this but I'm sure someone who knows will help.

Contact Doug Binder at Mountain Models website. He is very helpful.

Well I havent had time to fly yet, but I took alot more time building this fueslage. I made sure everything was streight, and even mesured from different points to ensure everything lined up. seems good. I also went to the local library and looked at some books on flight/ air planes. Very helpful. Everything seems ready to go. Tomorrow weather permiting I will test it out . Thanks for the help.
