Same problem I had yrs ago with the 583 from air screw, with his pipe,, he said to use  supper trap , which was BS, 

 Quieter equal less power .BUT IT DID ROCK & ROLL, 8300 rpm!!!!

We will of course need a complete report on the Prince as compared to other props you've used.  Another fellow, flying an S7 Rans sure likes his and has compared it to a Catto and ground adjustable three blade of some sort.  Ultimately he preferred the Prince. And of course you know who that is eh?

As a update to Steve Henry's highlander RX1. He is replacing the header for one that has longer primary pipes so he has better low end power and better throttle response. He is having trouble making spot landings for competition purposes. I have been using a different header here lately and it really changes the low end torque. Wide open power is stiil about the same.

If you get a chance could you post a picture of preffered header ,were along ways away from building the header  so no rush , thanks again for the updates

I looked at his face book page, He has a video of it running real strong, All I gotta say is holy shit that thing sounds like one bad ass bush plane. And if I am reading it right he is pumping Nitrous through it for 175HP on take off?
