I have a brand new 1/3 Christen Eagle and it has a TME smoke system in it. I ran the smoke system today for the first time and left the valve wide open. I did this on the ground with the wings off the plane and just to the left of the flight line of our field. Tom, another member of the club was flying 25ft. downwind of my plane and when I turned the smoke on he had to hussle out of the cloud because he could not see his plane. this sucker could give full scale sky writers a run for their money. the engine is a Precision Eagle 4.2 gasser and I could hear the load that the fluid made on the exhaust system. RPM stayed the same but the sound of the exhaust changed. Can't wait to do a hammerhead and have the smoke on and lose sight of the plane for a few seconds. Its going to be a rush.
