Dear All,
the trouble which I had with the Ail trims is solved. I just put the ignition batteries from the tail to the factory GC and the plane is now flying like my others. But unfortunately subjectively not as fast then I thought with my DL50 and a 19x14 wooden Menz prop which revolves above 8100 rpm (tuned KS pipe). The only problem I still have is the flip over tendency on landing. i.e. I must move the landing gear a little bit forward. Had somebody simular problems and a has a good hint how to solve it in an efficient easy way?
