Help troubleshooting please
 
On my XJ, I'm currently running:
Cc SV2
Cc BEC direct to a solar d772 at 7.4v
Dx3e
Orange rx ( sr300 was glitchy)

My problem is I power my TX then my rig, and even though my servo is centered, my wheels will kick all the way left and I get very little movement left to right even though my end points are all the way up. I took the servo horn off and re centered the servo and trim, but still get very little movement. I also tried another servo with the same results, unplugged bec and ran esc and servo to rx with the same issue, think it's my receiver but just wanted some input. Thanks in advance! Search yielded no answers, and yes I know where it is, and how to do a site search on google

Ive mentioned this a few times to some; but check and make sure you have good batteries in the radio..that can cause electronic issues...Maybe remove and re install the plugs into the receiver also just to check.

A weak battery will do that also..make sure it got charged and isn't bad.

Just a suggestion.

Plug it into the esc port on the rx, see if it still does it. If not, then you've got a tx issue. If so, its the servo.

Is your steering rate set to 100%?

Steering rate is 100% I know the servo works since it does it on 2 different known good servos. I'll have to try new batts in the radio that's one thing I didn't do

problem solved! narrowed it down to my TX, i got it in a trade as new, still had all the stickers on it, when traded i tested it and it worked great. opened it up and found that everything was corroded inside, like it had been submerged in water. Im a fair weather crawler, so i know it didnt happen from me.... cleaned everything up and its working now! thanks for all the input!
