About this Plan

Robbe Speeder E. Radio control sport/racer model for electric power. Wingspan 1100 mm.

Direct submission to Outerzone.

Quot: "Building instructions. Robbe Speeder E.

Specification:
Wingspan: 1100 mm
Fuselage length: 870 mm
Wing area: 25.3 dm2
Tailplane area: 3.6 dm2
Total surface area: 28.9 dm2
All-up weight: ca. 1200 g
Total surface area loading: 41.5 g/dm2

Radio control equipment: Any Robbe radio system with 4 or more channels, in conjunction with two servos and an electronic motor controller.

Sequence of assembly: In general terms the numbering of the kit components corresponds to the sequence of assembly; the number before the point indicates the stage of construction, the number after the point the individual component. Please refer to the plans, the building instructions and the parts list to ensure that you understand each stage.

To build the model you will need a flat building board on which you can tape down the plans. When you have to join components directly on the building board, cover the plan with clear plastic film beforehand.

Please follow the instructions supplied by the manufacturers of the various adhesives. Allow all glued joints to harden thoroughly before continuing with construction.

The fuselage plan includes the identification drawing 'O', which is intended to help you identify the die-cut parts. Write the number on each component, but do not separate them until they are needed. Sand the die-cut edges smooth before installing them.

Whenever you need to fit a component in an inaccessible position, or glue two parts together, be sure to leave any marked hole positions visible. Directions such as "right-hand" are always as seen from the rear, looking forward.

Notes on the radio system: Before you start construction, check that your radio system will fit as drawn on the plans. If you are using a different system from the one we recommend, you can still follow the installation scheme, but you will need to make allowances for slight differences in size.

Before beginning work, set the servos to neutral using the radio system, with the transmitter sticks and trim levers central.

Covering: It is important to keep the airframe weight of this model to a minimum; for this reason you should cover it with heat-shrink film. Follow the instructions supplied with the film. Please note that the wooden parts must not be sealed beforehand. Simply rub down the surface of the wooden parts with fine glasspaper, and remove all traces of sanding dust.

Building the model:
Stage 1, basic fuselage structure, parts 1.1-1.21:
Note: the fuselage sides are built as a mirror-image pair.

Glue the side doublers 1.3, the wing supports 1.4 and the tailplane supports 1.5 to the fuselage sides 1.1 and 1.2.
Mark the position of the main formers on the fuselage sides, measuring from the plan.
Cut the triangular longerons 1.6 to the exact length shown on the plan, and glue them to the inside of the fuselage sides. Fill the gaps between sides and longerons with glue.
Taper the bottom triangular longerons towards the tail end as shown in the detail drawing 'Z'. Sand the edges of the longerons and the fuselage sides flush.
Drill a 3.5mm hole in the rear main former 1.7 where marked, and trim it to the shape shown in section A-A.
Glue the front and rear main formers, parts 1.7 and 1.8, to the right-hand fuselage side, exactly at the marked positions, butting up against the wing support 1.4. Check that both formers are exactly upright. Refer to section A-A, and check that the rear former is the correct way round..."

User comments

Hi Mary, I found the Robbe Speeder E (oz12400) within your plans and I have built this model several times with e-motor (brushed and brushless) and also converted to i/c with an Cox Conquest. This plane is easy to fly and makes a lot of fun. Attached some pictures of my Speeders [main pic, 003-005].
Greetings,

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.
