A couple of our guys are flying the 50cc Yaks and they look and fly good. I was so impressed with the total package that I bought a 100cc Yak. MileHighRC is carrying them, although I'm not sure if he has bipes or not. What impressed me the most is the hardware that came with them. I thought like you they were cheap Nitro quality but after more detailed inspection I can tell you they are much better quality than that. Give Mike a call at MileHighRC and he can tell you what he has coming in as I know he has a container in route right now loaded with GoldWing planes. Jerry.
