I searched all the past posts and didn't seem to find what I was looking for. I turned my 12X on today hoping to fly and the screen kind of just blinked continuously. I tried to charge the battery with my Hyperion 720 duo...but I got an error. I put the charge lead in the pack and used a multi-meter and the other end (banana plugs) and it read 10.3 volts. Needless to say I went home. I put an old 10X pack in and it powered right up, though none of the memory was there.....which sucks. I resoldered the board of the 10X pack to the NiMH of the New(er) 12X pack and all seems to be well....notwithstanding all the lost memory.

I've read that the newer cassettes had a fuse instead of a diode for the older 10X packs. Would a failure of the fuse on the board wipe out the memory in the Tx? Has anyone else experienced this?

I ask because I hesitate to reuse the old board (diode) with the 12X if if weren't meant for it. I also hesitate to buy a new pack just to change it out to eneloops (which is the plan).

I'd appreciate any experience anyone has....
