Thanks for the prop recommendation. I have been using the Saito 150 with an 18x6W on my U CAN DO. It's fun but it keeps shaking the plane apart. Do you 3D with the 17x8 on your Saito 150? I think I must have bought the last 540 they had in stock because it is not on their website today. I hope that is not a bad sign. I finally saw the video of the plane. I can't wait to fly it. The guy in the video is very good but I don't think I want the prop that close to my face.
