I have 2 of these YAK-54's (one unbuilt) I would say that this is a very nice plane for the money, but there are some minor issue with build quality and the hardware is below par with U.S. Mfg's. Some of the hardware such as control horns, and clevises are useless. Another problem is the landing gear. The aluminum gear that comes with the kit is too thin and will collapse even under a normal landing. I reinforced my gear with a 3/16" music wire that runs the entire length under the gear attached with straps to the aluminum, which also serves as the axle for the wheels. The wheels are a little small. OK- now for what is nice about the plane. The overall quality of the plane is good but it takes a little extra time and patience to get things installed and lined up correctly. The YAK flies good! I'm powering mine with an OS 1.60FX with Slimline Pitts muffler, swinging a 20x6-10 TF prop. I have the CG set right on the wing tube, which is a little aft but the plane has no apparent tip stall problems. The yak will hover nicely, knife edges very well, but has some considerable wing rocking during an elevator. The instructions for this plane are basically just pictures and no help to the un-experienced builder, and definitely not a novice fliers plane either. Overall, not a bad plane for price. I'll try to post some pics of mine in the near future.
