Airtronics 94809 get extremely hot on the bench
I have had one 94809 stop working after one flight using a five cell NiMh battery. When I cycle other eight 94809's on the bench in an air conditioned room on a five cell NiMh, the servos get so hot that you can't hold them between your thumb and index finger. I don't trust these servos and may need to order eight Hyperion DS 11 AMB servos. Are these DS11's and 809's manufactured by the same company and rebranded or are they completely different electronics? I don't want to order the DS11's if I run into the same overheating problem.
I need the DS11's because they have the same output shaft as the 809's that I have in a sailplane with the RDS drive system.
Thanks for any input

Hello,
Those servos should be fine using a 5-cell NiMH pack. What transmitter are you using? Does your transmitter have a high speed servo mode like Airtronics' SSR servo mode that you're running in? Beyond that, and if your linkages a smooth and not binding, I don't know why the servos would become so hot. It doesn't sound at all normal. I would suggest contacting customer service directly and maybe send them back to be checked out and tested.
Sanwa makes there own servos. Additionally, they don't make OEM servos for other manufacturers.
Best regards,
