I have been flying RC for 17 yrs consistantly and had never had a servo fail ( key word HAD) Since January I have had 5 servos go bad that were only weeks old. 1 JR that did not work out of the pack. 1 futaba 9202 just stopped working while on the bench 1 futaba 9203 has power but want move, worked the last time I took it out. 2 robbe 250 digital servos one was intermittant and the other one cut out in the air. I banked left and that is where she stayed. That was my most evpensive crash so far, and the most painful since it awasn't my fault. I 've flown planks all shapes and sizes over this time period, I just over the last 2 yrs started flying helis and I love it but these sevros have to stop misbehaving. Just letting off steam. I hope Robbe will atleast let me pick another servo for the 2 bad ones. (not the same ones of course) I bought 8 of them they are all resting on shelves in my shop.

Jeff, I just think you were over due for servo failures... Look on the bright side, none of them happened in the air... So you got lucky in the end... (when you coming to Florida so we can go flying?)

Watch you battery voltage real close .. Since I have been flying helis I have noticed two things will kill a servo .. One is vibration and the other is letting you battery voltage drop to low .. The servos on a heli take alot of power to keep going because they are all moving all the time .. With a plank the servo only moves when you want to turn then goes back to neutral and doesnt move again untill you want it to ..I went through more servos in a yr flying helis than I did in 10 yrs flying planks..

Make sure you use the mounting groumets in the servo ears

I use only 4 cell battery packs.
Jason , 1 did go bad in the air! Took me for $400.00
I do use the rubber grommets
I never let the voltage drop to low unless they are being cylcled.
The vibration could be a problem, I have noticed my ys 80 does a good job vibrating.

Thanks

The YS80 sure does a real good job if it managed to vibrate the new one in the pack to death .
