I'm trying to figure out what prop to put on a Hanger 9 Sukhoi with a GT80. I'm turning 6200 RPMs with a Zinger 24x10 and the plane won't hover. I've done searches in this forum and started a thread in Giant Scale forum and can't find any help. I'm thinking I need a 24x8 or a 24x6. Does anyone have any experience with this? What RPMs should I look for? What prop do you use. This is a great plane and engine but without some more omph I'll have to move on(or order different engine).

Thanks
Phil
