Propeller Flange Arm for W&B

[rpigeek]

Anyone know the arm distance to the propeller flange for weight & balance? After replacing the Sensenich with the e-Prop I have to adjust the weight and balance and forgot to measure it.

Of course you don’t want to measure to the flange - you want to measure to the center of gravity of the prop. It might be easier to get three scales under the wheels and re-do the whole plane with the new prop.

Yes I want to the CG of the prop, but I know the center of the prop to the flange distances so If I had the flange I can run the numbers on the whole thing. Yah, I have a set of scales, so might do it anyways, as the previously avionics change weren’t handled very well.
