I took my FLY 9 apart to look at the internals and locate an intermittent problem with it. This time it was not the rudder pot but the elevator pot which had a wire that needed re-soldering. During manufacture hot melt glue is used to secure the wire to the solder connections (to prevent them from breaking away during movement of the flight stick yoke). The glue was the problem (which I wont go into here). Its been fine since and thankfully that rudder pot is very easy to get to but I was expecting to see a conventional pot rather than that pre-set miniature type held in place with glue. If mine packs up again I will transplant the AV8R wired elctronics in and hopefully get one reliable product from the two........
(...but, touch wood it's been fine so far and I do use it a lot!)
