Roscoe, I have installed the Sensensich propeller purchased from you a few weeks ago and was able to pick up 5-10 knots of airspeed. You may remember we discussed other upgrades such as the Power-Flow exhaust and the Surefly ignition upgrades (or maybe I discussed that with Mat?) but am still having issues with exceeding the redline on the tach even with the new 61-degree propeller. If I add one or both of these upgrades, I am still left with an engine that has more power than the propeller can use – is that right? That being said, would it be worth it to upgrade one or both of these items? If so, why? Perhaps there an STC that would allow for a more steeply pitched prop?
