my plane was working great until... an alerion servo stopped moving
one thins that is cofusing me is that it seems its getting a signal but it just cant move
i have started moving the servo when giving it a command and it tries to work
it even started to go crazy, and it woulde not respond to what i said it to do, and it even went so crazy that it started digging itself into the wing O.o
what is going on with the servo? do i need to get a new one? or is it not getting a signal from the receiver, or the transmitter
i am so confused
i think i need to get a new servo, i did some tests and i am sure the servo is just broken
that still does not explain the servo going crazy, oh well, that was just plane werid

You sure it isn't just a broken wire? I'd plug it in to a spare receiver and "jiggle the wires around a bit" if the servo cuts in/out, jitters or just acts differently when you move the cable about, you probably have a broken wire that is making/breaking contact when the cable is moving.
If it is just a broken wire I could probably fix it for you.

i am getting a new one anyway, but i might ask my dad (an extremely good electrian) to fix it, and i would keep it for a spare
thatnks for offering
, i would rather not waste people's time
i looked at the wires though, it looks fine?
i am no expert though
You did not mention what type of servo it is. What surface was it on and in what type of plane?
I usually start by plugging in another servo and see if the new one works. If it does I take time to check any connections to that point really well including the Rx. Return to operation could be due to just unhooking and pluggin in the new servo and the problem comes back.
If the new one works and you cannot induce a failure with other connections, then it is time to think about what may have made the servo fail. Items I have seen. Vibration of the surface or component taking out the potentiometer. The servo binding at the limit of travel and stalling the servo. This causes a lot of heat build up and will burn them out. Another issue is ganged servos that have not been matched that fight each other. This is usually on very large models.
I have only personally had one servo fail since 1985 due to something other than a crash.
That one would have a "bounce" in it when returning to center from one direction only. The pot was going bad.
Hope these suggestions help
thanks for the new advice, it will help
now i am new at this sport, so i am not going to try adn fix it all, and i dont want a failure of it, so i am just buying a new servo
it is a wing servo, roll, and its a 3D plane, (Typhoon 2 to be exact)
(i tried the y-connector with the other wing servo, the y works fine)
i checked just about everything, and i looks good
i took apart the servo, looks good (to me)
i am just new at this and i dont want a failure in mid-flight, so to me $13 is insurence that my plane wont go into a uncontrolable roll
(i dont have much money, i am 14 and i have to buy the planes myself) to me $13 is better then a battery going exploding after a crash, and then $200 for a new plane
Hi Everyone..
I spent the weekend fitting rpm arms and tecno sway bars on my e-revo.
yeah it took me a couple of goes till i got comfortable putting it together and taking it appart.
Any way after i finished the installation i plugged in a set of batteries and tested the steering. when i steered to the right it seemed ok, when i turn the steering to the left the travel was loads more and i noticed a clicking sound.
When i put the car on the groundand tested the steering at first it did steer but the clicking sound was pretty bad and a few seconds of steering left and right and then the steering compl;etly stopped working.
When i lift the car off the ground the steering works again but still makes the clicking sound.
The sound and the vibration when clicking definitely feels as if its coming from the servo so i opened up the servo and had a look inside couldn't tell if anything was Wrong so put it all back together and the problem is still there.
so i need to know if it is indeed the steering servo, and if so suggestions for a good replacement set would be appreciated. or is there something else it could be although i am leaning towards the steering servo.
Thanks.
