Hello, I have a newly built buggy with a hobbywing motor / ESC + Spektrum STX3 radio. There's a noticeable lag in throttle and steering response.
I noticed it is interfering when another radio that I have is turned on. Should I re-bind the other radio or the Spektrum?

To my knowledge the STX3 uses a different protocol than used on all other Spektrum models, It is also the most cheapest radio set.

I would sugest to look for someting different like a budget model from Futaba or Sanwa

Spektrum is notorious for glitching because they use direct sequencing, more info here:

Yeah, but in that same article, the STX3 is noted as using FHSS, so direct sequencing would not be related to the issue in this instance, If that’s accurate.

I don’t know what options are available when binding with the STX3, but for the latest DSMR radios, you have the option of 22ms, 11ms, or 5.5ms - the former two are used when Telemetry is on. I’ve seen YouTube videos where Telemetry is on with Spektrum radios, and yeah - I definitely wouldn’t want to race (or even drive) at that response rate... so I guess in a non-Racing scenario, it depends on how badly you’d want Telemetry. For crawling it’s probably OK, but I wouldn’t want to run a car at high speeds based on what I’ve seen.

That being said, I’m using a Spektrum DSMR radio bound at 5.5ms, and I haven’t noticed any issues personally - but again, the article is quick to point out that environmental factors can play a part on whether you have that kind of interference or not. Having said that, I’m not leaning one way or the other - this is definitely one of those YMMV scenarios.
