Title: Servo burnout under no load Post by: prabu85 on June 10, 2017, 06:48:39 AM Rudder servo got burned out under no load or signal input from TX,whereas Elevator servo was working fine,Could any one suggest how to prevent burn out.
Title: Re: Servo burnout under no load Post by: kiran rc on June 10, 2017, 08:32:05 AM Did you use same kind of servo's for both elevator and rudder?If not some of them have a greater voltage stability while the others don't. Otherwise, the only suspection is a 'short' in the circuit board.

Title: Re: Servo burnout under no load Post by: kiran rc on June 10, 2017, 11:59:18 AM Emax 9gm Metallic gear servo was deployed in rudder. It's clear from above that it's overvoltage problem. Keeping the voltage below 5.5V can ensure a good stability and avoid burns for small analog servo's.Title: Re: Servo burnout under no load Post by: rishabhbarma on June 10, 2017, 05:50:04 PM If all else for eg voltage is ok, just don't use avionic crap.
A friend's servos on brand new stealth got screwed mid flight in maiden. All groun tests were ok. Servos simply failed. Title: Re: Servo burnout under no load Post by: prabu85 on June 12, 2017, 06:21:07 AM Thanks for sharing this information.

Title: Re: Servo burnout under no load Post by: sanjayrai55 on January 11, 2018, 10:45:06 AM This is surprising, and not good. Have you taken this up with RCB? Please do, they may well need to take some corrective action
Incidentally, which RX battery were you using? Or is it an electric and powered through a BEC Title: Re: Servo burnout under no load Post by: gaurang.1972 on January 11, 2018, 11:20:32 AM This is surprising, and not good.
