Silly question... Using a servo tester can avoid or diagnose servo fails on fly?


Every time when I fly, the servo fail of one aileron or elevator goes through my mind.
I wanna know if exist any form ,to check the servos.?
I think ever about this because have offroaders and 2 times this happened, one time on my 1:8 buggy nitro causing brownouts and full aceleration and other on my crawler, but a plane is a lot more dangerous i think.

Once the servo is in the plane, it is probably easiest to test them as part of your pre-flight. Look for good movement, listen for odd sounds.

I've been flying for a few years now and i've never had a servo fail on me yet ( touch wood) but i do check my planes before i fly them,like checking all hinges on the ailerons,elevator and rudder buy making sure they are all well glued in.

I also check the servos to make sure they are all working and moving correctly,if you use digital servos you some times get a buzzing sound which is normally on some of them but not so good on an analog servo so watch for that.

There is a servo tester you can buy which i use to center my servos and make sure they are up to the job,i'll leave a link to the one i use at the bottom of this post.

I do a range check once i get to the field and then i'll give the plane a quick once over to make sure everything is still working as it is meant to,then check to see if my ailerons,elevator and rudder are all moving in the right direction,after that i'm good to go flying.

It sounds a lot but it isn't really and it's good practice to do these sort of checks to make your flying safer and a happier flying experience.
