As a newcomer I wanted only the best, so I bought one.
Its not the easiest to use, it has a limited range, mine didn't go to 15 degrees, and I ended up selling it on ebay and bought a JR which I find much more useful.

K&S works fine. Cheap & cheerful.

Actual degrees measured are possibly less important than its use as a comparison meter.

The Vario is the best one I have come across. It even has a bubble level in it.

Why does it need a level in it? Surely you are setting the pitch relative to the flybar?

And if you don't have a flybar?

Is that the only reason?
Surely up until fairly recently there were very few flybarless models available.

I'm not running flybarless myself, but almost any model can be converted to flybarless with the right electronics today (CSM/Mikado).

I always make sure the flybar is square to the mainshaft first. I guess you could argue the level in the pitch gauge, but I find it easier to check the level than to look through the pitch gauge and level it with the flybar. Your mileage may vary.

I'm with the Dude on this one. The bubble level is much easier to be accurate with than lining up with the flybar. So it's quicker to use and more accurate. I epoxied a bubble level to the top of my eflite gauge, and then made a thingy with a bubble level that would sit on my flybar for my TREX 450, and it's a ton easier to work with than trying to see whether I'm lined up with the flybar. I prop up the flybar to hold it level, and then I know that when the bubble on the pitch gauge is lined up I'm done. I hadn't seen the Vario before, but now I'm sold on it. In addition the the bubble level, I like the design which stays balanced on the blade's CG. My current pitch gauge is heavier to the right, so it wants to tell me my pitch is higher than it actually is. Thanks, Dude!

kcass518 I made the same setup as you for my Mini Titan, works great. I find it a lot easier then trying to do it by eye.

Whatever makes you happy!
I have no difficulty whatsoever lining up the pitch gauge with the flybar.

Depending on the mixing ratio and the angle you hold the flybar at when you are measuring the pitch you can get different pitch readings on the main blades.

The robart one is the most accurate I used. You make sure the table you are on is level, then lock the flybar in place with a level on it then measure your pitch. Very accurate and if done carefully your tracking will be perfect when you fly. The other gauges are near enough as the pitch readings are really only a guide anyway, you'll end up tweaking the pitch when you test fly and you'll probably have to track a blade. I don't use the robart gague anymore, just a cheapy one, it's near enough.

Like you say, I would suggest that with many models, if not most, the pitch readings are in fact only a guide.
With all the slop on my shuttle, if I set it up with a pitch gauge only, it wont hover at all.

The last three builds I did, I setup carefully with a pitch guage, and the tracking was dead on on the maiden, and they flew beautifully . . . maybe I'm not doing it right?
