F-22 Raptor

This is the most stable foamy I ever built, especially with the KFm4, which I use in all (almost) my foam planes and recommend. The KFm4 eliminates the “kite like” behavior, and put the plane on a rock solid predictable trajectory, with or without wind. The behavior is similar to a much heavier airplane.

Once you get the hang of it, the takeoffs are simple. The trick is to give it enough power to allow the plane to gain some speed, without being influenced by the engine torque. In my particular case with this Power Pack, the right spot is close to 60% of power. As soon as I can get my hands at the controls, I apply full power and pull the nose up!! Easy!

I had some difficulty in obeying to the proposed construction method. That system of cutting and folding did not convince me. So I chose to do the opposite. I cut the bevel on depron sheet and folded into the fold, instead of folding out. It worked quite well, but I do not know if it works better that the proposed method. The next one I do will be with the proposed method, so I can then say whether it is better.

As Dave Powers says in one of his videos, this airplane does not work well with wing flaps, but I am a bad listener, so I had to test it myself. And I do confirm the opinion of the designer/pilot.

The flaps only become useful if the aircraft is equipped with a landing gear. In that case the landing flaps allow a faster but flat approach with the landing track. The implementation of flaps is not advantageous for belly landings.

The decoration was made with water-based paint applied with brush (light gray). After that I applied the Tamiya Color Spray darker gray (I believe it was TS-48 Gunship Grey). The decals were done with a laser printer on decal paper.
