Hangar 9 angle pro
 

Im sure alot of you guys use this, do you trust its accuracy, I checked my incidence on my Vanquish, seems like its very inconsistent readings as it jumps all over the place

As the battery gets weaker, the meter will start to wander; extended periods of time on also tend to cause some issues. If you can limit your time powered-on, you'll see a reduction in wandering.

Or just use a Robart meter.

I couldn't find a similar battery here locally so i used the BEC line (6V) from a 30A ESC, powered by a small 2S Lipo. Mine used to wander a lot at first, but now it's very consistent. Measuring all the incidences and downthrust on a plane may take a while, but with the Lipo battery you can work as long as you want.
If it seems to give inconsistent readings (by that i mean oscillations inside 0.2 deg range), i just calibrate it again, but it doesn't happen too often.

Hey Alex, how do calibrate the unit?

It's on page 3 in the instructions manual: http://www.hangar-9.com/ProdInfo/Fil...Pro_Manual.pdf

I bought 2 of the Angle pro meters and was never able to get them to be consistent, even with new batteries. Still sitting on the shelf......

Mine had a loose fit between the digital readout and the "slide in holder". I jammed in some paper or something to take out the slack. I've been using it for 5 or 6 years. Once the slack was taken out its been fine. It doesn't have auto shut off so be careful. I've been thru a bunch of batteries.

When My Angle Pro died I picked up one of these: Wixey WR 365 Digital Angle Gauge w/Level. I even found a spot to mount the bracket off of the dead meter so I could still use the accessory’s

Mine is fairly new just doesnt see to be consistent, I can get a measurement to set, then turn it off and its totally different when I check it again, look like I will be getting a robart.

Where did you get it

Thanks Alex

Several years ago I saw a digital angle gauge advertised here in RCU and purchased one. It cost quite a bit and required a laptop with certain minimum requirements to work.

I used it and found it to be of outstanding quality. It's consistency when measuring deflections of surfaces was measured in 1/100 ths of a degree as I recall. In other words far more precise that we ever need in Pattern. For set-up, it has been unsurpassed. Determining wing incidence and empenage angles was more challenging to set-up and get meaningful results.

For these measurements, I have yet to find anything more accurate than a flat surface and a height gauge. I aways return back to this old and trusted technique for setting wing and stab incidences. Wing flatness and precision is also verified this way, with a height gauge....

I got mine at the local woodcraft store... they had as good of a price as I found online.
