Don´t know what turbine you are using, but in the purple ones there is a option to dump the gas
cannister after starting the engine, minimizing the chances of a crash and burn...

Just as caution note, a friend here had a flame out in his plane, due a header tank malfunction, and he could not bring it back to the strip. The plane vanished in a hill. and while we walked thru it, I said:"well, at least it couldn´t catch fire, because the turbine was not running and the gas dumped" , then we saw smoke coming from behind the hill! the thing while gliding blind, severed a high tension wire, and it started a fire in the vegetation. After recovering the plane and stopping the fire, (many people came to watch the action) we realized that the other wire was hanging too from the post.. and then it fell too! For our luck nobody was near it, but it could been fatal is someone got hit.
