About this Plan

Pitts S1. Radio control scale biplane model. Wingspan 1000 mm, for electric power with geared can motor.

Quote (google-translated from the German): "Building instructions, PittS S 1. General information: The numbering essentially corresponds to the sequence of the construction process, with the number before the dot indicating the construction stage and the number after the dot the corresponding component. Get an overview of the individual construction steps and the use of the individual parts in connection with the construction plans, the instructions and the parts list before you start building.

To create the model, a construction board is required, on which the 1:1 scale construction plans are stretched. For work steps that are carried out on the construction board, the construction plan must be covered with transparent film.

The processing instructions of the individual adhesive manufacturers must be observed. Allow all bonding points to harden thoroughly before continuing.

The identification drawing '0' attached in the middle of the instructions makes it easier to find the stamped parts. The stamped cuts are also marked with capital letters, which you will find again with the individual parts in the parts list. Number the stamped parts accordingly. Only cut out the parts when you need them and then plaster clean.

Notes on the motor: The model is designed in such a way that either a motor with gear or a motor with direct drive can be installed. When choosing a geared motor, please note step 17, step 18 is omitted. If you have decided on a direct drive, please follow step 18, step 17 is omitted.

If desired, more powerful electric motors than those listed can also be used. In terms of space, the installation of e-flight batteries with up to 14 cells is possible after expanding the battery compartment upwards. These changes are at your own discretion and are not reflected in the plans and instructions.

The covering: We only recommend covering the model with Robbe heat-sealing film. When processing the film, follow the enclosed instructions. Please note that the wooden parts must not be primed. The surface of all wooden parts is simply sanded down with fine glass paper. The grinding dust must be carefully removed. Finely sand the plastic moulded parts and paint them with a good synthetic resin paint. The model is decorated with the enclosed decor pictures. When placing the individual decor images, follow the illustration on the cardboard box.

Construction stage 0: Wing edge curves, tailplane leading edge, rudder trailing edge, parts S.R., SH., S.S., 0.1:

Notes: The parts are all made in the same laminated construction from 6 balsa strips 0.1 (1 x 5 mm) each with the help of the templates S.R., S.H. and S.S. manufactured. Speed glue is used.

Cover the supporting edges for the strips with adhesive tape on the respective template. Begin with the wingtips. Place 6 strips 0.1 congruently on top of each other. Place the strip bundle at one end of the template and fix it with Tesa strips. Press the strips onto the template without leaving a gap and fasten them with several strips of Tesa. Allow speed glue to run between the joints of the strips. Press the strips together again. Cut off the ends of the strips that are over the ends of the template. Pull off the tape. Glue the strip joints at the points that have not yet been glued. The exact processing of the parts takes place in the respective construction stages. The wingtips 1.16 and 3.15 are required twice each, the elevator leading edge 6.1 and the rudder trailing edge 13.4 once each.

Stage 1: Shell of the upper wing, parts 1.1-1.17:

Note on the construction of the wings: The ailerons are built together with the wings and are only separated in stage 15. In the wing plan, the right half of the wing is shown in its raw state, the left half with the ailerons removed. Unless otherwise stated, speed glue is used.

Place the area plan on the building board and cover with cling film. Assemble the lower and upper main spar, parts 1.1 and 1.7, using appropriately cut 2 x 5 mm adhesive strips as seen from above. Staple the lower main spar 1.1 and the auxiliary spars 1.2 to the building board according to the plan. Insert the center rib 1.3, align it exactly with the center line and glue it in place. Place 5 ribs 1.4 each on the spars, align and glue in place. The two remaining ribs 1.4 are only required in construction stage 5. Glue in the two end ribs 1.5. Glue in the intermediate ribs 1.6. Fit and glue in the prepared upper main beam 1.7. The end rib 1.5 is centered by the tension of the main spars and is therefore not on the building board. Cut the bevel for the scarf on the right leading edge 1.8 as seen from above. Place the leading edge on the ribs and glue, making sure the edge rests on the building board. In this way, the step for the lower planking results. The rib 1.5 does not touch the leading edge. Slide the plywood reinforcement 1.9 into the slot in the center rib 1.3..."

    ScaleType: This (oz14822) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Pitts_Special
    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.

* 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.


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.
