i am having a strange issue with the A2 flight controller
Basically it is this, i have my flight mode switch set to GPS,ATT and Failsafe, this is done to test the failsafe function without shutting down the transmitter, obvious.
On the ground everything works well failsafe initiates on radio tx shut down and failsafe set on the flight mode switch., flight in GPS and ATT is all fine and switching between the modes is fine.
If i initiate a failsafe in the air using the flight mode switch the A2 flight controller initiates the failsafe and will return to the home point and land fine.
The problem is that when it initiates this it locks me out, changing the flight mode switch back to GPS or ATT has no effect and the failsafe proceedure continues until it lands.
Once it has landed and shut off the motors i can regain the flight mode by toggling the switch.
has anyone any ideas on this one, it is obviously very concerning as i can not regain control once failsafe has initiated. i have not tried this in the air by shutting down the transmitter for obvoius resons.
I have nothing additional items such as iosd, hubs etc attached to the A2 controller except the landing gear.
Radio is a Futaba 14SG linking directly to the A2 controller, previous to this i was using Graupner via the S-Bus adaptor and had issues between flight modes and also the failsafe issue.
Flight mode issues have disapeared but the failsafe is still there.
The A2 is running the current version of firmware.
Any input regarding this would be appreciated as i need to sort this out.
