Think my radio is dying..

[brushlessboy16]

I think my Airtronics M8 is starting to die, or at least the potentiometers..

Ever since I have had it, its Center is different from that of newer radios, Dx30 and 2.0, It seems as if the potentiometer is Offset compared to the wheel... I need to set end points in the 30's on the right side of the range, and end points in the 120's on the left. and then i still dont get full travel on the left side...


And at the end of the steering wheel travel to the left there is a dead zone where any servo will not move when the tx wheel is.. All this is pointing to the steering potentiometer.. does anyone have any insight on this?

Well im not paying for anything, i have a few radio pots from my Usb transmitter endeavors... Im going to get the radio now and tear it down.

Interesting I'm getting similar on my dx3.0 - I have everything set to max ranges in order to get the ESC to bind or get reasonable steering.

i was about to contact spektrum about it - any idead if user fixable?

ITs an easy fix if you know what your doing.

Sent you an IM.

the part number for the dx series steering potentiometer is 109TU

Small, square black potentiometer.

I wish radios would make the pots an easily replaceable item able to be done by the end-user. Or better yet, change them to a rotary encoder.

encoder would be way easier..

Pots suck.


Air tronics makes it easy.. the whole front cover of my radio comes off with 3 allen screws..

Spektrum basically said send it in for non warranty repair and they'll have a "look" at it...

They say they don't have many pot issues...

Have you guys tried resetting the travels?

I had this issue with my DX3R, where the steering wheel would always be to the right.

After I reset it, CORRECTLY, it worked.
When I tried it, I'd move it, to try and "calibrate" it at the wrong moment, and would end up with the problem.

Before doing surgery, try doing the full radio reset..
