About this Plan

Robbe Wega. Radio control model. For .35 - .60 power. Plan nr. 3169.

Direct submission to Outerzone.

Update 16/10/2018: Added kit review from Radio Modeller, November 1977 thanks to RFJ.

Quote: "Test Report: Dave Cronin builds the Robbe Wega. This ROBBE kit builds into a compact aerobatic job and a real 'star' performer!

AS THE FIRST kit from Robbe tested by Radio Modeller, the Wega makes an interesting introduction to their concept of kit design and production. It is a streamlined and rather aggressive looking low-winged machine, of very low aspect-ratio, for four-function radio and (it says) .35 to .61 power. The contents were fully described in the September 'RM Trade News', but the main point that strikes one is that, although the kit contains a wealth of nice quality wood, the only fittings included were the two main u/c legs, wheel collets, clamps, and a packet of mylar hinges. (The nice looking scale type noseleg shown in the plan and on the boxtop is not included - nor is it, apparently, in the Robbe catalogue).

Getting it together: The wing is built up, rather than foam, and I was delighted to find spruce mainspars supplied. Ribs are all pre-cut and need only light sanding. Having built the two panels, ready to join with the ply brace, I decided that the '45mm under one tip' (just over 1-3/4 in) was too much for this sort of aerobatic machine, so I joined the wing with the top surface flat on the board. This was my only 'mod' and I believe it was justified. The centre section requires to be wrapped with glass fibre bandage, but that in my kit was not quite sufficient.

The fuselage goes together well, being built inverted on the plan - but it's necessary to refer to the illustrations of the engine bearer assembly frequently as it is easy to misalign these. The formers are marked to take cables but, as these are not supplied, I used pushrods, only needing to open out one former to take them. The sheet balsa sides have ply doublers at the wing seat area, and the turtle decking is only Ain. sheet balsa wrapped over. This tended to give just a slight 'starved horse' effect - perhaps a planked decking would have been better. The canopy is supplied, not in moulded form, but as acetate sheet, from which quite a presentable one can be built up.

Finishing: I covered the model entirely with heat-shrink film (that fancy pattern on the wing is actually in green and gold) and, with its radio gear installed..."

Update 12/10/2019: Replaced this plan with a clearer copy, thanks to Harald.

Quote: "In a discussion at RC-Network recently some issues with the Wega planfile came up - bad fitment, incorrect size for example. Now, attached you will find our update (warped lines reduced, size fitted to printer page size, cleared markings). We will build a few of these Wegas during winter time. Harald"

User comments

I would like to send you a Foto of my "Robbe Wega", built in 1976 [more pics 004]. It's still flyable. Coming winter I'll build an electro powered version. The Wega has been a part of my life since the 70s ....

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.
