Re: [RCSE] Servo damage?
About a year ago I had a problem with some HS-205MG Hitec servos, or so I thought! On landing they would seem to find a new center. I would retrim and center them and the next hard, flap dragging landing would have them out of whack again. I though something was moving/slipping internally in the servos. The problem was actually my fault. I had replaced the stock servo horns with Futaba brand horns, what I though was the same fit to the splines on the output shaft of the Hitec servos. It was in fact just slightly oversized. It held up fine to normal flight loads and seemed fine when putting pressure on them by hand, but on hard landings where I didn't get the flaps up quick enough it would jump a position and end up out of center. After finding the problem I replaced the horns with stock Hitec horns and have had no problems since. Check that the horns are not moving on the spline under extreme shock loads like when dragging the flaps on landing.

I seems something internal to the servos has permanently moved the neutral location. The servos seem to work fine, no slop or noise. Should I just subtrim them and not worry, or has some damage been done? The servos are Multiplex mcv2 digitals. Tom Seitz RCSE-List facilities provided by Model Airplane News.

Keep landing like that. You've got servo savers. ;) Regards -- Stephen Syrotiak Southern Connecticut RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]

No kidding...I wonder if a "system" like that would be reliable in a slope combat plane! Stephen Syrotiak wrote: Keep landing like that.

[RCSE] Servo damage? Just wondering :-)
Why did you go the RCSE instead of contacting Karlton at MPX first? That's rhetorical, as in doesn't deserve an answer! Just wondering though, as you can see you got a bunch of useless specualtion from some nice guys hoping to find SOMETHING to reply to. But inspite of that, fairly often guys while post a question to the RSCE for speculation, when the could have gotten a real answer from the supplier. Someone like you, who can afford that kind of quality deserves better than speculation :-) Karlton is the man, the source. He'd know, and if you have a problem only HE can actually do anything about it. Oh, yeah he's a really good guy too.

Re: [RCSE] Servo damage? Just wondering :-)
Sorry Gordy, but I have to disagree. There is no more way for Karlton to know whether his servos moved or his linkages came loose or bent versus whether the servo(s) have sustained damage (unless he takes them out and mails them in). The guys gave him some good suggestions of things to check -- no sense sending the servos back to multiplex if the problem is elsewhere. Seems a bit critical to call the suggestions he got "useless" since they made perfect sense. And Karlton IS synonymous with RCSE in my book -- it's a sure bet he will be one of the people to respond to a multiplex question, so by posting here he got feedback from Karlton AND some other smart folks Sorry I didn't make it out to the SLNT contest Sunday -- hope you had fun. Good luck in Orlando, sounds like they are ready for you! Have fun.

Re: [RCSE] Servo damage? Just wondering :-)
Well if the servos work and show no signs of gear damage. Then something moved! first look at what could have moved or compressed.. Like hinge tape or links. BUT I would check the servos if they moved more then a little; To check the servos in the plane first before going to more aggressive measures. Start with taking the linkage off the servo arm while the radio is off and moving the servo through its range of motion SLOWLY feeling the arm for any skips or binding in the gears. If a skip or a bind is felt change gears.. If your worried at all send them in we have a very lonely service tech even the Maytag guy thinks he is a boor. How hard did you land?

Re: [RCSE] Servo damage? Just wondering :-)
BTW with a MCV2 you will strip the servo horn spline before the case or the gear goes. Check the servo horn.. Smooth Sailing, Karlton Spindle http://www.MultiplexRC.com RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
