Jumper T8SG still fails on DSMX/DSM2

Hi Folks,

a friend of mine has two copters (KingKong ET100 and self a build whoop) with DSMX receivers. Both copters drop off the sky frequently. Apparantly random failsafes/lost connections even in very short distance (a few meters) between TX and RX! According to some posts in this forum we tried to switch to DSM2, tried many cli bind parameters, used orange option in the dsm(x/2) protocol, tried different frame sizes (fast option 11ms vs 22 ms) but the problem still persists. In Betaflight we used Spektrum1024/2048 accordingly.

So to eliminate some possible causes I tried a stock DSMX transmitter from a Blade Nano QX and bound it to both copters. I have tried it with 3 charged batteries after another and have not experienced any brownouts/failsafes yet. We both have the Jumper T8SG V2 plus and with both transmitters we experience the same brownout scenarios.

So I am pretty sure that there is still a problem in deviationtx with DSM2/DSMX protocol at least on the Jumper T8SG (V2 plus).
Does anybody have ideas or similar experience with DSMX and DeviationTX?

Today both copters had brownouts even with the stock transmitter. So it does not seem to be a Jumper T8SG problem,

We have so many problems with the DSMX/DSM2 that we will switch to FRSKY asap.
