Hi there,

I have a Goldwing MX2 58" which now has 120 flights on it..

The elevator has a fairly cheap spektrum digital servo on it. When I first turn on, radio binds, I test all servos, and the elevator seems to hesitate (doesn't even move) then after a wiggle on the stick, shoots to life, and then works fine.......

Haven't flown it since I saw this, and can't get it to repeat itself... do servos do this when the potentimeter track is worn around the center point?

Any ideas or suggestions? Is this a common problem? Could it be the radio or tx? For the life of me cannot get it to do it again.... but for sure its done it today, and I thought I saw it last time I flew as well, but thought I was imagining it!

120 flights, its done say 12 hours of flying... do servos wear out that quick?

Any suggestions welcome!

I would get the servo out and replace it with a known good one. Send that one in to Horizon and see what they say about it. No sense in losing your plane.

anytime you suspect a servo or linkage or wire or switch, get rid of it and test a new replacement.
Nothing worse than having your "suspect" problem suddenly fail obviously..

Any more ideas with this would be appreciated....

I bought all new servo, and extension, fitted it and the problem was immediately worse.....

Then after 30 more tests, could never get it to repeat.....

Could it be the pots in the TX? Its a 9zap, maybe 1000 flights on it.... The servos appear to stick in one place like they are catching on something (they aren't) then suddenly jump to the correct position...

Have hardly flown the plane this month, and have tested in 40 times, cannot get it to repeat.... its getting to the point where it would be cheaper to just crash it than waste anymore time..
