Default servo going crazy - wants to zig zag when i wanna go straight. help please!

anyone else having this? though it wasn't bound right, so i did the bind thing again. at least its not the throttle. it cant be the TX, servo does it when its on or off. video shows i still have controll, but it still has a mind of its own. we dont have cordless phones here.




i have made sure the ESC board is not touching anything and it is shrink wrapped.

what else can i check?

sounds like a fried servo.

check the signal wires from the servo to your ESC.

make sure there are no bends or breaks in the wires, and make sure they are all plugging into the esc port tightly.

other than that, see if it persists when another servo is plugged into the ESC

also make sure all you batteries (in the charger and Tx are new and strong)

could just be your Tx losing connection

Looks to me like a servo that can't find it's center point.

I'd either try that servo in another rig or try a known good servo in the Micro, see what happens...

Plug in a nother servo ( any size)

thanks. tried another servo plugged in which worked fine.

so i took the stock servo apart, nothing i could see that looked odd. put it back together and seems to be fine now. time will tell. at least these parts arent to spendy being micro and all.

Mine does it every now and then. I've checked all my wires, nothing seems to be out of the ordinary. After a couple of packs it does it less, but it's still there. Hopefully it goes away. When it's really prevalent, I can hear a high-pitched whine coming from the servo, like it's getting signals to do something but can't decide what.

How did you tell Losi? Email? Phone? Do you have their contact info handy?

same problem here. emailed losi, they want me to send them the servo AND the esc/rx to diagnose which it is. also, they need my recipt, which is gone...

so i took the servo apart, found an eyelash inside ?!?, put back together, and voila it works.

go figure

Heh looks like a JR servo when they go bad, could be the smallest particle inside when it tries to find center the piece pushes it too far and misses, dunno. Reminds me of JR tho :P

Hmm, I just bought one today, a BND. Does the same thing. Bound it twice to my DX3 and same thing. Bound it to my DX3R and same thing. Gonna contact Losi now.

Maybe there IS shit inside keeping it from finding center like Katon said, and it just needs to be worked out. I'll run it a little and see what happens.
