Updates the steel tank only provides around 2 min 40 secs of run time which just doesn't give me enough flying, Being spoiled over the years with much more duration its frustrating to hear the engine crackle lack and stop abruptly. The bladder tank ended up pushing too much pressure to the engine and needs a restrictor fitting. It looks like the effort making the bottle tank has paid off I now get just under 6 mins and allows me to land at idle after a satisfying flight rather than forced down by an empty tank. Using a Cox Lil Stinker 4 x 2.5 prop gives me enough thrust to climb out vertical.
