RE: determining proper thrust
thanks for all the info. I flew the plane a few days ago and fortunately it flew great how the engine was (a few degrees of right thrust). I also followed Rodney's suggestions. The wind here is constantly between 10-20 mph so it is hard to tell 100%, but I flew it parallel to the runway several times and increased throttle as it passed me and I didnt notice the plane pulling consistently in any one direction. Thanks for the help!
