Static RPM

[horsepower 24]

I have a 3 blade 68 inch Powerfin prop on my Skyraider, havent flown it yet but have done lots of taxiing and did a runup with it tied to my truck.At full throttle it read 6340 on my digital tach,its a 582 with a C box. Powerfin says it should be around 6000.What are you guys running yours at?Thanks Randy

6300 on take off... 6500 ish level flight full throttle...this is on a tiny tach... my needle tach was soooooo far off when I put my new engine in that it was worthless. I do my mag check by ear... anything more than 150rpm is pretty easy to hear.

With my IVO I set it for 6150 or 6200 on the run up check when I set my mixture. It will give me 6450 or 6500 on take off. But I can bump more pitch in at cruise. If your not turning 6500 on takeoff / climb out then chances are pretty good that your leaving alot of performance on the table. It all depends on what your mission is. Getting out short and climbing, or a better cruise
