yes jim, every one of the fires i said were gas, were in fact gas, not glow fuel, which i have also seen burn in a crash.
all but one of those gas fires was ignited by a battery/electrical short heating up and igniting spilled fuel after the crash. the other was a backfire into a gas loaded cowel.
i have even seen a glider catch fire and burn post crash, again a battery/electrical short.
for me, i am not saying no rules, i say rules should apply across the board, no seperating out power systems, and they should be enforceable and enforced.
