So I finished my build and put it up about a week ago. It was a little windy, so I'm not sure if my problem is from that or a build issue. Anyway, it seems to have a noticable amount of dutch roll (at least what I think is dutch roll). What I'm seeing is that there is some ocillation around the roll axis with the pivot about at the wing box. i.e. nose and tail wobble around a line drawn from nose to tail but the center section of the fuse is fairly stable. I'm wondering what might cause that and whether it's fixable and if any of you have seen something similar.
My other question is how you find the roll performance of this model? It seems a bit under-responsive to me, but I also haven't completely explored the full range of movement for the aileron servos yet.
By the way, Smok1n - nice paint job! Not being overly artistically inclined, I've made a bit of a gamble and bought a spare canopy and decal sheet for the Parkzone Spitfire Mk IX. I think it's very close in size to the FT Spitfire, though I haven't tried anything out yet as I want to make sure it's going to fly well before I spend much time detailing it.
