Usually I don't buy used airplanes, and more, is very unusual for me to buy crashed airplanes, but for all rules are exceptions and Katana is one, my friend Bo had a slight accident with this airplane and since is moving only to electric planes he made a proposal and I decided to buy this second hand crashed airplane together with my field friend Vitor.

The old proprietary, friend Bo, speaking with my actual co proprietary of the airplane, friend Vitor, in the ground a few of Bo's airplanes including the Katana that he sold to us. An interesting point is Bo designs is own airplanes and we can see one o those in the photo. It's very usual we get together to fly all over this small country.

Here are the half wings, that are attached to fuselage sides and get together by an aluminium tube and hold in place by a spring and one screw per panel. It's a small plane (1,35 m) more or less, control surfaces are very large allowing very fast rotation around this axis.

The airplane was configured to use one standard servo for elevator, but since Bo used a twin nano servo in the back of fuse I decided to use them also (not to leave more open holes) in my case I used the cheapest ones in the market 0,9 Kg torque and they work quite ok. Surfaces are also very large and effective.

The worse part of Bo's ideas, this airplane is called Katana .50 (guess why) but Bo find a .50 much for the airplane so he decided to use a very nice engine (Irvine .36) but not for this aircraft, it flies, of course it flies but is very under power, but this problem is solved and the airplane is now dragged by another .50 Webbra.

Vitor, refuelling the animal, the fuel with .36 last for almost half an our it seems to never end, after 15 minutes you are already tired, so you pass the airplane to next guy and he can fly for another 15 min without a problem.

It's a fantastic airplane, it handles like a trainer, be careful not to stall because it needs more time and height to recover from a stall. Some speed is required while landing, once I made this error, leave the airplane "hanged" on the wind and at about half a meter from the ground the wind stop and the plane dropped like a rock, the result was a broken landing gear and the rest of day watching how the other guys fly.
