Graupner MX-20 Failsafe problem


Guys I have a problem withthe mx-20

I'm using it for a mikrokopter, my receiver is the GR-32 (4 antennas), and the connection to the mikrokopter is via SUM channel (single cable).

I set the failsafe as described in the manual, selecting POS (position) for all channels, then I press SET and I get the message "Position Stored". But nothing happens if I turn off the radio. What is the problem ?

Thanks

I think you have the newest firmware in gr-32 which doesn't work with mirkokopter failsafe properly. I have the same problem. In others receivers I downgraded the firmware in gr-32 I can't do that I don't know why

A new message in an old thread!


I just bought two new GR-24L, and updated the Firmware, to 3.78 from 3.76. Neither of these work with Mikrokopter. When I shut off the Tx the MK still shows full transmitter strength!
I have an oler Gr-24L with 3.75 which works fine. Now if Ican just figure out how to load the old firmware? Update Assistant won't me.

Mikrokopter repsonds:
Graupner did change the FailSafe function in the receivers. If you use the latest Software on your receiver you have to go into the Menue "Setting & Data view".
There go to the window "RX Fail Safe Vx.xx" and change the "MODE" of channel 1 to "OFF". Now the copter will again receive the lost signal.

Mit freundlichen Grüßen / Best regards

That will not repair the failsafe fully. When you will first switch on the receiver (before transmitter failsafe wont work

I have 3.78 and it doesn't work at all. Even if I switch on transmitter first.
