Bugs 3 mini "twitching" with jumper plus

I have owned a jumper t8sg v2 plus for about a month now and am loving it. I updated the firmware (thanks to this site and the helpful community here) and it is working great. I have no issues with any models I fly with it except my recently purchased mjx bugs 3 mini.

It binds, flies, and I have all the channels programmed (arm, lights, flips, and acro/angle). When flying around the motors twitch a few times fast then smooth out. If it hovers it is smooth but while moving (any stick input), it is twitchy and the motors stutter a few times then fly smooth for a few seconds until they twitch again.

I have tried recharging the battery, rebinding, messing around with channels and trims, but it still acts the same.

When I use the stock transmitter to fly, it has no issues and flies smooth with zero twitches. I'll try to include a video of the flight to show the "twitching" when I can take a smaller size video I can upload here.

Has anyone else experienced this or something similar? Any suggestions to try? I have flown my regular bugs 3, xk x250, e011, and mantis85 all with no issues. Any help or suggestions would be greatly appreciated.

I have the same problem when flying with my devos,it seems like it loses the connection at times even at short distances..

Yeah it's weird it doesn't matter if it's 5 feet away from me or 100 feet it still acts the same. It never really loses control so much as the motors just seem to pulse on and off. I have had zero issues with range or anything with any other models flying on the jumper plus

C0ckpitvue 777 is it only with recent builds or a problem you always had ?

This protocol should work properly, I fixed a bug recently (flips couldn't be disabled after being enabled ...) but nobody else has reported this issue so far.

The initial build there was a glitch also,I never said nothing because I just thought it was me.

Can you check with a few different TX IDs ?

Should I use the spreadsheet?I will try different Ids but they need to be provided,right now the weather is rainy but as soon as it clears up I will definitely try and report back.

I mean Fixed ID, not the ID in protocol option, choose whatever you want, just try with a few different values (rebind required).

I also noticed the flips cannot be disabled after binding, I need to turn tx and b3 mini off, switch off then turn on tx and b3 mini. I installed the latest build I found when I updated the firmware about a month ago

That's normal, the fix for flip issue was merged a few days ago only.

@jbuck, as it seems you easily reproduce the problem, can you try with a few different Fixed IDs as well ?

I wonder if I should re-update since the flip issue was solved and see if it changes the twitches...

My fixed ID is 123456
Do I erase and re-bind to change?

I deleted the fixed ID, randomly changed it, and re-bound 5 times. Every time the same issue is still there. Would it help to take a vid of the twitching and try to upload here? The vid I took already is way over the 2MB limit so I'd need to take another lower quality one

Ok, I'll try to understand what's wrong.
