Thanks everybody...

my ideas are more "extremes" [>:], as i cannot get te car nearby the flying field (only to unload/load is allowed, but for flying she must be away...) and we don't have any flying field house...

one of my Extreme idea was to use a model tire warmer, the ones used by the R/C model car, and heat up the gas bottle for a couple of minutes, and then start the turbine...[8D], the only problem is not let the bottle overheat..

but i think that keep the gas bottle inside my jacket will be enough....
