RE: Can anyone explain INCIDENCE to me?
Quick question: How do you measure incidence if you don't have an incidence meter? I wanted to experiment with my 4 Star 40 (I built this from a kit, first build) as it seems to want to balloon on me a lot, especially with the first flight or so. I am not sure why this happens. It seems like I have to always give a lot of down trim to this plane every time I take it out for the first time of the day. Then as time goes on during the day, I can come back on the trim some. It is also somewhat sensitive to wind which most people tell me that low-wing planes are usually not affected much by wind. Could this be an incidence problem? I am pretty sure the CG is correct but I might check it again tonight when I get home from work. My father-in-law (who got me started in this hobby and also has a 4 Star 40) told me some time ago that the style control rods (plastic rod inside a plastic tube) the 4* has tend to warp in different temps and need to be trimmed every time you fly. Is this correct? Thanks in advance...
