Quote: "Building instructions for the Robbe Baron powered sailplane model: The powered sailplane model Baron has been designed from original factory blueprints of the French sailplane Breguet 902. The highly functional shape of the fullsize craft permits a simple and robust construction of the model replica. The finished model gives a highly elegant impression and provides excellent flight characteristics.

Baron is an aerobatic model and may be remotely controlled via 3, 5, 10 and 12 channel functions. In the case of the 3-channel equipment the functions should be used for left and rightrudder plus down elevator. The model however becomes truly versatile only at 6-channels plus. By providing trim the model can easily be adapted to nearly all prevailing wind conditions.

In order to obtain a maximum of versatility from this model it was designed from stretch as a powered sailplane. This permits making training flights without recourse to helpers, which are required for tow-launching. Installation of the Enya 15 RC (order No. 7108) or of the Enya 19 RC (order No. 7109) is recommended. If the model is to be exclusively flown as a glider, the engine should be replaced by a suitable block of balsa mounted in the recess for the fuselage nose and attached to the firewall by 2 bolts.

Proper CG position is obtained by moving the power supplies and the RC equipment accordingly. He who wants to towlaunch the model must attach a tow hook to the pre-formed landing skid (fig.1). Diameter of the towline (order No. 5088) should not be leas than 1/32. Refer to Robbe catalog 1965, page 23d, for practical hints re the installation of receiver, servos and trim linkage.

Preliminaries: Assemble parts 1 through 6, which consists of 2 parts each. Cement fuselage longerons 2 to part 1, as per plan. Recess 3/64 deep (saw or file), to accept part 6b (refer to broken line on drawing of parts to be cut out). Cement fuselage aides 6, 6a and 6b, one on top the other, using contact glue (Rudolfix). Be sure to provide one left hand side and one right hand specimen.

Splice wing spar 52,56 and nose planking 83 according to plan and cut to correct size. Prepare formers, ribs, wing tongues and parts of wing tongue boxes. The blade of steel 80 is notched with a triangular file and broken apart. Degrease parts 80, roughen surface, if desired, and cement in wing tongues with UHU-plus.

Fuselage and empennage: Attach part 1 to building board, block up front end starting at station 0, as per plan. Blocks should protude approx. 13/32. Cement formers 3, 4, 5. Attach prepared fuselage aides 6, 6a, 6b with UHU-coll and secure in position with pins until dry. Add parts 7, 8, 9. Be sure to watch for proper spacing of part 9 to landing skid.

Fit formers 10, 11, 12 next. Assemble wing tongue boxes from parts 13 and 14 (one right hand and one eft hand box req'd). Secure boxes by two M 2 bolts on either side, if desired. Fit wing tongue boxes to framework, cement. Glue parts 14a, 15a, 15 and 16 in rosition. Tack-cement part 17 at four points. Cement part 1.3 to part 20. Provisionally cement to fuselage with 2 blobs of cement. Fasten part 22 to part 4 with pins. Cement parts 19, 21 and 23. Pre-bend canopy Stringer 24 and cement.

Attach planking 24a, avoid undue warping and stressing. Drill two 1/8 in holes through parts 16, 4 and 22 (according to plan), which are to accept the dowels. Holes in part 16 may be framed with resin impregnated paper (not contained in kit). Insert dowels 37, add tail skid 26, cement with UHU-plus. Stick to dimensions given in plan, when cementing parts 27, 28, 29 and 38. Sand fuselage framework smooth.

Assemble vertical tailsurfaces from parts 31 through 36. Cement to fuselage and to part 27. Add parts 31a and 30, sand assembly smooth. watch the dimensions given in the plans, while adding parts 39, 40 and 41. Fair in at part 40 by sanding. Cement skid 42 in position. Sand fuselage once more and apply porefiller.

The horizontal tailsurfaces are assembled from-parts 43 - 49. Cement part 50 to part 43 with UHU-plus. Mount part 51 in elevator and cement. All control-surface hinges are fashioned from cloth ribbon 87.

Main plane: Cut out plan of wing and glue parts together. Lightly rub with grease or oil to make printed lines visible on backside too. Plan may be used to assemble the wing right on it. Pin part 52 and lower auxiliary spars 53, 54 to building board, add ribs 59-78 gussets 74, top spar 52, leading edge 56, trailing edge 55-55a, auxiliary spars 53, 54 and spar 57, to which the spoiler will be hinted; make sure that assembly is free of warps..."

    ScaleType: This (oz12758) 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/Bréguet_902_Cinzano
    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.

User comments

Have tagged this one as scale now, since according to the introduction text in the instructions, it is actually based on the drawings of the Bréguet 902.

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.
