Your observation is noted. . .however, tests with our Rhino prove the best cooling of pipe, air frame and the added thrust are realized when the end of the nozzles is between 1.25 and 1.50 inches spacing from entrance to the pipe. This is most definitely been tested and works. The reason is, the pressure area at the entrance to the pipe is enhanced when set up this way. Many of our customers who previously complained of "hot" fuselage after flight, could not believe the difference when set up this way. We include within our manual, a chart of measurements for each of our turbines. Maximum/minimum ID pipe size is noted as well.

Readers. . .please check with your specific turbine manufacturer as to their acceptable turbine/pipe set up measurements.

Thank you,
