<span style="font-size: small">Sean,

Congratulations on getting your design in the air. I've always been impressed with those people in the hobby who create the designs that the rest of us fly. If you would like to experiment with props, I have some spare APC e-props sizes:20X13, 20.5X12WE, 21X13 that you can use. If you are interested then contact me offline.
