Propeller clocking to #1 TDC

[aeroaddict]

A high time supercub pilot mentioned that the propeller should be clocked to #1 cylinder TDC to assist in hand propping and balance to the engine firing. The prop should be about 10 o'clock (and 4) when #1 is coming up to the compression cycle.

Hand propping I don't think we have to worry about, but the balance comment was interesting.

With the light weight catto prop is there a clocking preference?

This is on a EX-2.

Thanks

I like the timing your friend mentioned. It just looks right on a Cub. And if hand propping is ever necessary this is where you want it.

I don’t see how positioning it like this could allow for better balance though. All props should be dynamically balanced in my opinion.

Yup, should look just like that. I agree with your balance comment.
