OK, here is little more about that model.
The original plane is Zlin 526 produces here in former Czechoslovakia. It is a sport stunter. We do not like war birds very much. Could be memory of two world wars here in Europe, so if you see semi scale in stunt it is rather sport plane than a military ship. So the choice for Zlin was done because it is very similar to our c/l stunters. We share our field with an aero club, which owns the original plane in those colors. The difference to the original is the airfoil (thicker), the tail (larger) and lettering – on side is now name of owner (Alexander Schrek) his sporting license instead of original imatriculation and some jokes like “Made in Slovakia” instead of “Made in Czechoslovakia” just to irritate or Czech friends, because the town “Zlin” where are those planes produced is not on Czech side of border.
The model now is aerodynamically identical to my last “MAX” model. The only problem while designing was sweepback as my calculator is able to make aerodynamic analyze only for straight hingeline, so I had to do it by hand. However it was successful and model was prepared for World championship 2002 in Sebnitz. Unfortunately problems with Magnum .52 prevented him to fly and Alexander used his second model.
The wing is our foam “MAX” joined to make dihedral and sweepback. The tail is also from “MAX”. Little problem was installing landing gears. The original had tubular landing gears retractable back. So it was little difficult to install it to foam wing without a spar. The solution was simple semi rib installed on finished skinned and cored wing. It is visible on pictures. The tube is fixed by one coaxial screw from top of wing.
The fuselage has open bays. The original had spars / ribs construction with alu upper and bottom turtle decks. The model is similar. It has upper balsa turtle deck, flat bottom and open bays sides giving the same look and the result is stiff and light fuselage. The wing is on 4 screws, while tail is fixed.
The finish is not glossy polished surface. We use automotive 2 component colors. Then we sand it and polish by relatively rough water based polishers without grease allowing next coat. The result is very smooth shiny but no glossy surface, as we do not use clear dope over. The black ink lines are applied only after finishing. They are done by the same color type (not ink) and they are not sanded after, so the result is visible also on shiny places and you can also feel it if you touch it by fingers. I really like it. Alexander did it one long evening at home so I do not know exact details, however he told me “never more” … so as we say he did it twice: firs and last time at once

Here are some pictures. The first is original plane prepared for long flight with optional tip tanks not used for aerobic flights.
