tIANcI:

Now it makes sense. The 14x7 prop probably underpitched the motor. The Balsa Nova had a very thick wing which made it a draggy plane: you could keep increasing the power but it would not fly appreciably faster. In the end, I settled on a 14x8.5 which was just about right: I could fly the sportsman routine at an almost constant speed and it had enough vertical for a nice stall turn. With the 14x10, the speed went up a little and I had to use the throttle a little more, but the vertical also got taller. I an guessing in the range of 300 ft (~100m). With that, I had time to make corrections on the way up as well as on the way down. I would expect the Angel to behave similarly.

I will start working on the plane shortly and I will run the motor/prop/battery combination through the wattmeter just to check that my memory is correct.

Once again, thanks for the info.
