Very nice work! I have been following your progress eagerly. Love when someone takes the path less travelled.
I missed what motor you have. It looks like an Axi F3A. Many have used an APC 20.5x14 very succesfully on that motor. It will draw around 90A but it can handle it. They recommend a 20x13 which is a little slow on most airframes. I would try the APC versions of both and then order the one you like best in carbon to help you make weight. The Falcon CF props are very nice but a little pricey to experiment with.
