Adjustable Propeller Angle gauge- which one to get?

[kmach]

Hi All, I am looking at getting a gauge for setting the pitch , or getting the blade angles equal to each other. i was wondering what others have , ones they have tried , likes, dislikes etc... I just about ordered a gauge from ACS but decided to ask a few questions first. ACS has an electronic one and a Warp Drive gauge, I was leaning towards the electronic one for some reason.

kevin , i have the warp drive protractor . it works pretty good . as you probably know , it uses a bubble . the acs cube would be nice and probably a little more accurate , if a guy could justify the price .

I have never seen a warp drive gauge, except in the ACS advertisement. I have never had or used any gauge as of yet so I am a rookie in the gauge area. I have the Sensenich ground adjustable prop , from their instructions the blades should remain equal by the center hub setup, but I would like to confirm with a gauge. I want to have a gauge before I start to experiment with prop settings .

My hangar partner has a ground adjustable Sensenich prop with the pin gauges. He found them to be very unreliable in setting the pitch. Could never get all three blades set at the same degree. He ended up using the Warp Drive protractor to get his blade pitch angles set the same.

That is really good to know.

I agree, the Warp Drive Prop Protractor is easy to use. It fits many different size props, it's very accurate and you don't need to level the aircraft.

I used it yesterday to check a McCauley on my Cardinal RG.

Great tool. Well worth borrowing for the task.

Hi Steve,
where on the Sensenich blade was he taking the readings ?

I have fooled around a bit with the warp drive protractor now and am using this method; I measured 3 '' in from tip on both blades, drew a vertical ,level line .

I aligned the protractor to the line vertically,and level.

I have the protractor on the pilot side, and rotate blades to take angles on pilot side only, blades are measured from floor to bottom of blade to keep all consistant. I have not changed any settings yet, but I have a difference of 1 degree from the two blades using this measurement method.

I sent Sensenich an email asking where on the prop to take the angle measurement, but no reply as of yet.

kevin , warp drive instructions are to use the front plate on the prop hub to set the vertical on the protractor bubble for the reference . i use a level to get the blade horiziontal on the pilots side of the airplane then install the protractor at the prop tip . i think the trick is to get the protractor installed at the exact same spot on all the blades . if you can use the warp instructions let me know and ill send them .
