Flew the Extreme Flight Extra 300 78" tonight with the pipe. It is simply an incredible flying plane...I have it setup for 3D and even on the first flight I was quite comfortable with it after 5 minutes! Did some aerobatics with it and it was simply sweet! I was very happy!

The engine powers it very nicely. The Extra with the SAP-180HP and everything in mine came up fully loaded, ready to fly at 11.5 pounds.

I have some heavy duty grey silicon hose (about .200" wall) on mine with about a .100" gap on the pipe and so far so good...but only have 1 flight on it and some running time on the ground. I used 2 rivets on each tube (side)...which I was not nuts about right now...but will figure something out really nice in the next few weeks. Still have a ton of other new parts on the burner.

Anyway...it's taching 9500 rpm on the ground with the special 3D prop which is 18.5 inch in diameter...it pulls unbelievably well! Will do a pull test sometime soon.
