Actually, about 1.5 years ago I was driving by the Giant Scale Planes store so I stopped by to take a look. Right up in the front was a Yak 54 72" (I think it was the 1.40 size). I met Irwin, the owner and asked him about the covering that looked so good. I thought that the colors were Ultracoat, at least they looked it to me. BTW, the fuse was fiberglass. Irwin proceeded to give me a lecture about how all coverings are the same chemical composition and if I thought that Monokote, Ultracoat and Chinacoat were different then I should go back to school and re-take chemistry. Made me feel like a jerk. But I really liked the plane so on an impulse I bought it. About 2 weeks after I brought it home I decided to start the model. It sure was pretty. There was an instruction sheet inside that had some drawings but did not have a CG listed nor control surface throws. And the instructions left allot of the assembly up to my imagination. So I called Irwin to inquire about the CG and throws. His response was "you shouldn't have got that plane if you can't figure it out". And he was very condescending and curt. I really should have tried to return it but instead I went on the internet and figured out the approximate CG. I used throws similar to another plane I had which gave me about 1" of elevator throw.

To make a long story short, the throws were WAY too much and I barely got the plane down on the maiden flight. During that landing the LG block broke. I was so disgusted with the experience that I turned to my buddy (xxspeed) and said here, if you want this POS then you can have it. Otherwise it's going into the garbage.

That is my experience. It does not reflect the experience of others. I think the CMP made a great product. Only to be destroyed by an arrogant US distributer.
