I would also highly recommend either setting the acft.cfg for battery always available or extending the battery life with FSUIPC.

I have not had any problem with power going off if the aircraft was sitting idle (power turn on and engines not running) for quite some time. I don't have the increased battery power checked in FSUIPC either.

I did notice this though. I turned the Avionics OFF on a different aircraft that I had been flying before switching to the BUFF. It took me a few minutes to figure out why the FD switch would NOT stay on when I switched it ON (at all other times it stayed on like it should). This means that:
1. You need to tie the Avionics switch to a short cut key combination (mine CTRL+SHIFT+A) so you can turn them on if they are OFF.
2. Make sure the default Free Flight flight has the Avionics Switch ON (this is the recommendation for most Add-on aircraft).

I'm seriously thinking of doing what CoolP has done. Change the power from 30000 to 22000 tp try it out. But first I'm going to uninstall the B-52 Driver and re-install the B-52 BUFF Exterior and then save the aircraft.cfg before "upgrading" to the B-52 Driver again, so I can compare them. I'll report back on the engine power rating that it had.
