In January I purchased Jumper Tx 16 pro and the R8 rx.
I updated the OS and also updated the multi module firmware.

as Im rolling down the runway, the outrunner shut off. ( esc programmed to do this)
reason: the R8rx unbounded. Set all up on the workbench and found that I could not re bind. After a few discussions with the hobby shop that I bought it from, we managed to re bind after a few tries.
while adjusting the RSSI signal, it went to zero, and the field where the multi module version is shown was gone and replace with multi module not detected .
so, I deleted the bin file from the sd card. Re downloaded and and placed in the sd card. When attempting to re flash the module with the firmware I got an this:
error no sync this message is a bootloader issue. So, Im told by the owner of the shop that I need to re flash the module with a circuit board (sorry, I do t remember the circuit board that needed to be temporarily soldered on the the internal module).

I had tried to other new R 8 rxs but to no avail.

i sent the rx and rxs back for a refund.
it looks like Ill be purchasing a Futaba or Spectrum.
