How did you get the case apart?

I didn't. After all the suggestions to not take the case apart, I figured out another way. I soldered a rod to the case in the center of the dent and pulled. A light tap with a body hammer at the crease and POP went the dent.

Its funny how things go from one extreme to another.

Was just talking to futaba to see when they were going to address some of there well known issues ,and the guy told me they had ,the new transmitters now come with a coupon for a free shovel LMAO .just kidding .Roger

PS: glad to see the motor will live to see another day .cool Idea about the dent pulling ,will have to try that on a tune pipe .

Doubt you'll get it to work on a tuned pipe, the AMT case is stainless steel, not that tough to silver solder to, a tuned pipe is aluminum, if you don't burn through it, you'll probably fracture it when you try to pull the dent.

I use LiPo's in my tx's, did he not pay attention to the voltage? Id like to find out more on this battery dieing.

one of our flyers had the same problem with lipos in his transmitter this summer. The voltage stays up for a long time and you get complacent about charging. The meter indicates the voltage is ok, but when the battery dumps it does it NOW.

a lipo battery nearing the end of charge can show fine at take off but totally die in the space of a five or six minute flight, voltage dropping so quick it might not even trigger a low voltage alarm.

when a lipo shows voltage at say 9.5 which would be ok for nimh/nicad, it's already too late.

Hi Gary,
Sorry to hear about the crash... $#it happens... any idea why the Li-po dropped voltage? Was the Futaba Tx a 14MZ which has its own Li camcorder battery, or a Tx with a replacement Li-po?

I recharge my TX lipo at 11v if I remember right, Id have to go check, it takes a couple months to get that low.

I don't think that you can get an accurate condition of Lithium ION, Polys or Mag unless you put a descent load on them. Say 1 to 1.5 amps. I doubt if any transmitter be it Futaba or JR can give that type of draw.
