Re: Extreme flight YAK 88'' and DA85
I own the EF 88" Yak. Have a DA 50 with stock muffler on it. More than enough power. If you want crazy power, run it on pipes. A DA 85 would be WAY overpowered for that airframe. It simply isn't necessary. I have seen DA 85's yank lightly built 33% to 35%er's around with no difficulty.
