I've been having issues with my Duster build, and from all the positive feedback on this design I'm wondering if it's just me. I'm powering this version with the Power pack C motor, 9x6 prop, 30A ESC and 3S 2200 battery all have been used previously on my Guinea Pig. On my first flight Dusty was all over the place, nearly uncontrollable, and ended the short flight with a damaged power pod mount. Upon reflection I think it was a bit tail heavy.
I fixed the power pod mount and moved the CG forward to just in front of the spar. I also noticed that the elevator was not providing equal deflection on both sides. This is partially due to the glue reinforcement making the hinge point stiffer, but also the very thin connecting foam between the two halves. I reinforced this as best I could on a completed model and gave it another shot a couple days ago. This time Dusty flew better, but was banking hard left. I put as much right trim in it as I could and wrestled him to the ground without damage. I recentered my trims and adjusted my sub-trim to give him some right aileron. I tried another flight, but I had given him too much and I was unable to bring him in safely the second time.
During my initial setup I did center all my servos, all the throws were set via the throw gauge as I had done previously on my very successful Guinea Pig. I'm wondering if the ailerons are too large on this model and make it very sensitive to roll input. I'm working on his rhinoplasty, and should have him ready to go again in a few days. Before I go crazy and redo the wing with smaller aileron sections, has anyone else had similar problems with the Duster?
