When I set the pitch to 11 degrees the motor loads up. Seems to be ok at 9 degrees. Is this normal? Should I be able to fly circuits running 11 degrees?

Pitch Gauge
Dude, pitch on a gauge is just a number. I have three pitch gauges including a very expensive K&S digital pitch gauge and none of them read the same. Put in as much pitch as the motor will pull and don't sweat it. I use a pitch gauge only for initial set up anyway and then adjust the model to the real world. Works well. If my top end pitch suddenly drops dramatically, I'll look to see if the motor is worn or damaged.

GM1,

I believe one can read angles to within 1/8 degree on a good heli pitch gage. I know a reading is repeatable to within that.

Ah, but how good is the scale? Probably within 1/2 degree. Just for fun, I flipped the scale over and got the same pitch readings at mid-, high-, and low-stick positions.

So the question is, do we have the main shaft perpendicular (both side and front views) while we are measuring pitch, or not? If we do, our pitch reading should be within 1/2 degree..

If not, it's just a number, as you said.

why do you think you need 11 degrees to fly circuits?
However you can run +11 -11, cyclic 7 degrees.

Just do it.
