There is a lot of mis-understanding when it comes to trimming a model. One has to remember that one change or one thing out of whack will influence several things. personally I find it funny that people offer suggestions without knowing some important information. The first thing to do is measure the airplane so that you know where your starting point is. The other thing to consider is that this airplane has a semi-symmetrical airfoil. The stab is not adjustable so what I would do in this situation is to put a level on the stab and block up the tailwheel until the stab levels. Next take a strip of something strait ( I use a peice if 1/8" X 1/2" aluminum ) and clamp between thrust washer and prop washer. This will give you a good flat surface to place the level and see if your thrust angle is 90 degrees to the stab. If not shim until it is. Having this 90 degree relationship will show up during verticals and knife edge. Now if the airplane had a symmetrical airfoil I would say set it to +.5 degree. With this particular airplane I would start at zero degrees. Reason for this is that the semi-symmetrical does not require positive AOA to produce enough lift to support the airplane. Once you have these angles set test fly the airplane and see where the pitch trim ends up at 3/4 throttle. here is where CG comes into play. If it takes up trim at 3/4 throttle and climbs at full throttle then you are nose heavy. If it takes down trim at 3/4 throttle and dives at full throttle then you are tail heavy. The idea would be to adjust CG until no elevator trim is required at all and the airplane flys the same line from 3/4 to full power. Once that is acheived fly some verticals to see if it pulls or tucks. If it pulls you need to adjust the wing positive and reset CG for neutral trim. If it tucks you need to adjust the wing positive and reset CG for neutral trim. Once you are close you can fine tune this with engine thrust. Most airplanes will tuck in knife edge. An airplane with an aft CG will do it worse. If you move the CG forward enough to eliminate the tuck then the forward CG will throw other things out. The fix is to run a mix but if the mix gives more then 1/8" up elevator travel with full rudder then the CG is aft. Lots to digest but in reality just a frtaction of trimming an airplane. Being that you are in Sutter Creek I would be happy to invite you flying this Sunday. I know it is fathers day and for most that is an issue but I will be at the SAM's field in Rancho Cordova Sunday moring to afternoon.
