About this Plan

Zlin Z-50L. Radio control scale model. Wingspan 156 cm, for 6.5 to 10 cc engines. Scale is 1/5.5.

Quote (google translated from the French): "Introduction: Here is an airplane that is easy to handle - with this airplane a good pilot is able to push performance to the highest degree in competition. These assessments are those of aerobatic pilots about the real Z-50L, they could very well apply to the model; indeed, in flight, the exceptional qualities of the plane are found on the model, its elegant line is very pleasant, and its simplicity is a real godsend for the model maker (fixed landing gear of the scale model type, no flap etc).

Construction: It was studied in order to have a light but solid plane and remaining simple to build for an average modeller. It will be greatly simplified if you have a Dremel type electric saw.

As an indication, I spent only 250 hours to make the plane, the plan and the molds of the canopy and the bonnet; you will be able to obtain these last two parts, all indications will be on the plan, as well as the dural necessary for the train.

Empennage: They are constructed in two half-shells. (stab. and rudder). Contrary to what one might think, it is not longer because, if you make a second line of the drawing, you can build them at the same time.

Once the main frame has been glued (from S1 to S10 for the stabilizer and from D3 to D8 for the centreboard) bevel the false leading edge to catch up with the profile, glue the covering (soft 15/10 balsa) and the caps of rib.

Place the leading edge once the 2 shells have been glued (don't forget the 5 x 5 BD reinforcements in the center of the stab.).

The flaps are the most classic so no problem but be careful, it is necessary to put a wedge under the tail of the ribs so as not to have a twisted flap.

The empennages have silk-lined (put on hold). After only, make the cutouts for the hinges, spreader bar etc. The shutters will only be put in place after painting.

Fuselage: It is when cutting couples and different parts that we appreciate the electric saw because, for beveled parts (C1, C2, C3, F2) it is enough to adjust the angle of the blade to have a clear and precise outline. About the ctp used, on the plan I recommend from the ctp aviation 5 ply of 3 mm but you can very well use (this is what I do) ctp 3-ply 4 or 5 mm joiner because it is lighter, cuts more easily, is sufficiently resistant and above all is much cheaper. But be careful, some notches will have to be modified.

Build on the plane view of the fuselage, a ladder made of 10 x 5 hardwood rods with, at the front, the F1 reinforcement which fits into C1; this couple will be fixed at one end of the site (see sketch).

Paste simultaneously C2, C3 and F2. Glue the frames against the ladder strips (frame C10 will only be hollowed out after the fuselage has been formed); add F3 and the 50/10 wing seat reinforcement then the various strips.

For the formwork, where the curvature is significant, soften the board in hot water then, without gluing it, apply it to the frames, holding it with tape. When you unmold, the piece stays in shape; cut it to the exact size and glue it (you can use contact glue)..."

    ScaleType: This (oz14059) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Zlín_Z-50
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Are you sure this is a MRA plan? Where's the component jumble, the parts ratatouille? :)

Miguel no more ratatouille, that's the"nouvelle cuisine". Times are changing. Pit

Miguel, Mra continued for a long time before being "swallowed up" by Model magazine. The design of the plans and their size have evolved with the formula of the magazine. The plans you are thinking of are "old" plans. Mra has evolved in his presentation ;-)...

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
