I too have the EF 68" yak and could not be happier with the qualilty and flight characteristics. I have a 35% edge 540 with a DA100 on headers and cans and that 68" yak flies better. I let other fliers give it a whirl and they cannot believe it. I can only dream about how the 87" yak from EF will perform. Chris Hinson (owner of EF) said it flies better than the 68" and as long as I have known him he has always been straight honest. I have my 87" on order and plan to call DA this next week for my 50cc. As far as price goes, you get what you pay for... Jeff W.
