RE: Ultra RC 87" Yak Build and Fly
I'm surprised that there aren't more people building these here. I'm very impressed with mine. It's the best ARF I have ever bought. All I have to do now is mount the engine and cut the cowling. Can't wait to fly it. You can only appreciate the quality of these kits after assembling one.
One thing I'm wondering is how much to cut out for the exit air (using WA pitts). Also should I baffle the front and maybe add that air dam that creates a negative at the exit like a full scale plane (thinking about what the guy from Saudi Arabia did to his).
