Vintage RC Helicopters - Joe's Collection - MS-Composit Joe's Collection MS-Composit Joe William Richardson MS-Composit CH-47 Sea Knight (2007)
Bought in 2007 and was one seriously frustrating helicopter. Once set up then it was sort of OK but any attempt at trimming to make it better eventually made it unflyable so had to be reset and then trimming could start again. Mar 09 - Eventually found what might be the problem with the wayward handling; one of the side cyclic servo's on the front rotor was moving at only half the speed of the other two. The control system requires large movement for cyclic control but only small movement for pitch changes. Thus inputting a pitch change only gave a small cyclic change and was not really noticeable however, inputting a cyclic control resulted in a large pitch change and the nose would then significantly 'bounce' up or down. This would upset the whole trim requiring 'elevator' input which would compound things until it would near enough go out of control. In Sep-09 replacement servo fitted and again not quite as fast as the others though much nearer. Started from scratch and again spent ages trying to get it to be stable but without success. However teeters rubbers were very soft allowing the rotors to move a significant amount; about 50mm or more at the tips. Don't think that was right and intend to tighten up the teeter system to give near rigid rotors and see how that goes. MS-Composit Hughes 300 May 09 - Bought used, still to give a once over. MS-Composit Hornet May 09 - Bought used, still to give a once over. MS-Composit SA315B Ecureuil Sep 09 - Bought used, still to give a once over.
