Nicest Prop Pitch Fixture?

[gasman]

There is an app for that...... A good one is Clinometer + bubble level by plaincode.

You may need to check the calibration of your bubble level. A web search for ?how to calibrate a spirit level? should return several written and video procedures. If your level is out of calibration and Unless your level is a expensive engineers machinists level you will probably just want to replace it.

Set the level on any close to level surface and mark the location of the level.
Rotate the level 90? in the same location and the bubble should be in the exact location it was in the first test, if it is the level is ok.

A easy test the level hold the level on the wall with the bubble between the lines then draw a line on the wall.
Rotate the level 90? and check the line, if it is not level then draw a new line with one end on the first line.
Level is a line in the center of the distance between the two lines drawn.
A good idea if you are married put a piece of paper or removable tape on the wall first.

Is the bubble an actual spirit level? My digital level has a bubble but it's just an electronic picture of the digital readout, not a spirit level that's independent of the digital value. If my bubble was different than the digital readout I'd figure it was defective.

Most digital levels have a calibration function.
If your bubble turns out to be accurate but the digital value is not, perhaps you accidentally recalibrated when it wasn?t actually level.

Scott,
I?m fairly confident I have her set at 71.4 w/i .1.

Say, is it possible at 71.4 to get a high MP alert on climb out and it goes away at initial cruise?

Thanks,
Doug

The few in our fleet do this regularly.

With respect to MAP, I know what overboosting an C/S prop?d engine is and what it can lead to rather quickly. Any stories out there about effects on fixed pitched ROTAXs? Any more info out there other than it should be avoided..? If 27.5? is high on the meter, then is there a too high number for short durations like climb out?

See: https://legacy.rotaxowner.com/si_tb_...912-016-r1.pdf

That is ROTAX's Service Letter SL-912-016R1.

Section 3.1.3 pertains to MP and appropriate operating limits.
