    Could you recommend a prop for an AXI 4120/18 motor?

    I have a Balsa USA Eindecker that I'm flying with an AXi 4120/18 on 5 cells, and currently using a Graupner 14-7 prop. The setup provides way more power than I need and I never go to full throttle. I'm wondering if you could recommend a prop that might yield less top-end power but more flying time per charge.

    In your case 5s would use up to a 14x9. Theres not much to gain with dropping down to a smaller prop. Try the 13x8 or a 14x5 that might give you a small amount of extra time, but not much.
