I am not interested in starting a servo war. Karlton has done a great job for me replacing damaged Mcvs, 2, to be exact. What I am talking about is testing the servo by firing it up and torqueing the output arm with your fingers. I have just done this test with 2 MpX , 1 Volz, and one used Airtronics 141. I checked that the arms were down tight and the screw snug. One of the MpX has no rock. The other is noticeably worse than either the Volz which is Zero and the Airtronics which is minimal. I am concerned about slop in the servo because in F3J the quest is out for the lightest, strongest airframe, with light winning out. It is possible to get major flutter in the zoom, with possible airframe failure. I have flown Airtronics equipment for many years and have the following suspicions, I beleive that 141's used to be more powerful, they also seem to be less tolerant of long leads and noise. I recently helped Mark Taylor check out a Graphite F3J model. The servos were 141's and they were new. There was some definite noise going on in that model, and it could be unique to that model. What was going on was centering problems and chatter similar to a bad pot on the aileron servo. What I am concerned about is the build up of internal radio noise in my sailplanes. In F3J you are flying 10 and 15 minute rounds, and are inclined to stay with lift a great distance downwind, sometimes pushing the comfort limit. If you have a setup that is marginal it is going to show up in that situation. I am interested in others experiences, as I will soon be deciding what equipment I will fly in Greece in July. Any input would be of interest. LJ RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
