Not sure about SHR for savox, to be safe just use NOR.

I have same problem with you, how now? Fix?
Has anyone ever had a problem with their M12 malfunctioning and causing servos to move/twitch and sometimes get stuck when getting a certain distance between the Tx and Rx?
Over last couple weeks that when I took my D815 away from the Tx and got to about 40ft away, the throttle servo would start to twitch and sometimes lock on either throttle or break. I figured out yesterday once I got the M12 about 40 ft away (seems to be either next to power lines or electrical equipment) things would start to get weird and servo would move on its own. It would only do it to the throttle servo and not steering. Just to check, I reversed the servos on controller and then then the steering servo started to malfunction and not the throttle servo anymore...
I tried binding to a different Rx and tried different servos and the problem still continued with my M12. The last thing I thought it would be the problem was the M12, but when I re-binded the original Rx with my friends MT-4, the problem stopped. I had zero issue with it using that controller so obviously tells me something is going on with my M12.
Has anyone experienced something like this? There are others at the track with M12 and not having the same problems. Why would getting near other electrical boxes and equipment cause a disruption in frequency between the M12 and Rx?
Thanks

M12 glitching problems
I hope someone out there can help me with this issue. I have a 4 to 5 year old M12, I have glitching problems on an out door track. I have RX481 wireless attenas in both cars, at a distance they lose signal and bad things happen. I had wired antennas did the same thing thats why I switched to wireless. I'm considering a new M12 S Super but hate to throw good money after bad only to find that I have the same problem with the new radio. Thoughts???

However, those wireless receivers are not recommended by Sanwa for larger tracks, so that was my thinking on why your RX 481 was glitching. But if your wired receivers did the same thing and they were installed correctly, IE: antenna above the body, then I would strongly consider trying to find a friends remote or maybe someone else at the local track who would be willing to bind their remote to your receiver and see if the issue persists.

i seem to have broken two rx's at my last nat, one rx471 and a rx472, both seemed to work intermittently after impacts and both only in nitro buggy, the car would just die randomly....
they are about three years old, and were mounted with fairly spongy two-way tape to the floor of my radio tray box as they always were for the last 5 years
going forward i will wrap them in some protective foam or something and leave them loose in the box as this seems like a safer option (avoids vibrations)
basically i'd like to know if anyone has experienced this before and if i could fix them or if the receivers are better left alone?

I've had the same problem in nitro buggy and basically once the receiver is damaged it's toast unless it's got a damaged aerial lead, in which case you can split it and replace the aerial with a new one from somewhere like Banzai.
Moving forward try to put your receiver in between some soft foam free floating in your receiver box, I've found that to be far more effective at protecting from vibration and impact.

Need some input, I’m installing a new servo in my car. I’m trying to get the servo horn as close to 90 deg as possible but it’s off. If I use subtrim I’m at 120 Right on my transmitter. Should I use trim instead? If I remove the horn and try to put at different angle I’m getting the same problem but now at 120 left give or take. Any input?
