Hi all
Decided to attempt to repair the circuit board on my MSRX and resolder the aerial wire that had come off.
When I rebound the heli to the tramsmitter and put in left rudder the main motor cuts out and only powers up again when i put a dab of right rudder on.
I have only been able to test with the main blades not fitted as i still need to get a new set of blade grips amongst other things.
Have I screwed the circuit board or is this normal with the inertia of the blades keeping it turning when in flight.
Have just got myself a Nano however still struggling to get used to flying it and would love to get the MSRX flying again for a bit of practice and actual flight time lol.
Love these blade helis
Many thanks
Dave

Sounds to me like you've plugged the motors in to the wrong sockets and the main motor is connected to the tail connector socket. If it was working before and you've only re-soldered the antenna wire you shouldn't have broken anything. Just re-check your soldering job with a magnifying glass to make sure there are no accidental shorts.

For reference, the main motor socket is the TOP one and the tail is the BOTTOM one.

Just tried swapping the wires over and it is now working as it should.
Never even crossed my mind to try that,DOH
Thanks so much, your a legend.
Not sure whether to put her back together or sell on for spares now as all that practice time spent on the MSRx seems to have paid off and I'm getting used to my nano quicker than I thought. Gonna cost at least 25 quid to get all the bits I need to make a complete heli.
Toying with maybe putting cash towards an mcpx but don't tell the wife lol.
Cheers
