Good morning Reincarnate! Just my two cents worth on the CMP planes. These are stocked by other companies as well. Chief Aircraft stocks CMP, as does Raiden and AK-Models.

I have their Yak 54-140 and it is a well made airplane with the exception of the glue joints around the landing gear mounting block. Those joints were made with a glue gun by running a bead where the wood intersects with the mounting block and the former in front of and behind the mounting block, and also where they mount to the fiberglass fuselage. Make sure you reinforce the landing gear area and get some glue into the joints themselves. As for the firewall, it, as is everything else is built quiet well and appears to be quiet strong. I'm not so fond of their fiberglass landing gear on this model as I have broken the right landing gear twice on mine, and an aquaintance in Houston, TX broke the left landing gear on his. Not all that fly this model have had this problem, but several have. I'm making a set of aluminum gear, and my aquaintance in Houston has done this as well.

That's the scoop on the Yak 54-140, can't say about the others, but I have read other forums on their planes and all seem quiet complimentary, especially in view of the price. These planes are built a little heavier so they are not 3D planes, but fly quiet well otherwise. My Yak (72 inch wing span) came out at 13 pounds with an OS 160 in the nose. Mose others that I know of have come out a little heavier, with some at 15 pounds (with a gas engine). Many have to add a lot of weight to the nose, which explains the extra weight. After looking at photos of a full scale Yak, I noticed that the spinner backplate is some distance from the cowl and mounted my engine far forward (the spinner backplate is 1-1/8 inch forward of the cowl), and the battery forward of the firewall as well as the throttle servo, and I still had to add about 3 ounces to the nose, 2 ounces in the form of a spinner weight, to get a CG that was not tail heavy.

I don't know what you will find on their other models, but that's the scoop on their 72 inch Yak. There are several forums on other CMP models, and most are quiet favorable if your not looking for 3D.

Would I purchase another CMP Product?? Oh yeah!

One thing you will find in this hobby as in life is that: "Experience is a hard teacher. She always gives the test first, and the lesson sometime later!"
