I hear ya. I will be tryting the 17x6 next week. Will post my experience after that. I think if the 17x6 does what is said here, it will please me immensely. I just love the immediate and instant vertical takeoffs and fly straight up till it becomes a dot; everything else comes later. When I was experimenting with props when I first got the H9 over a year ago, I only tried 16x8,16x10(I think) and 17x8. I remember it performed bad on the 17x8 so I stuck to 16x8 since. Now I have to try 17x6. Thanks for the information guys. Vim
