About this Plan

Stratos. Radio control sport delta model. Wingspan 1030 mm.

Quote (google-translated from the German): "Show flying, fox hunting and ground acrobatics are the three most important tasks for which the 'Stratos' delta model was developed. It should have excellent fast and slow flight characteristics and sufficient manoeuvrability, but at the same time be extremely simple in construction - the whole model essentially consists of a 20 mm thick, flat styrofoam plate.

The delta Stratos flies very stably and can be flown with engines from 3.5 to 7.5 cc displacement. Equipped with a 7.5cc engine with tuned pipe, it is so lively that it can perform absolutely vertical take-offs, and an out of site vertical climb.

When hunting foxes, these flight characteristics are of course of great advantage.

The total cost of building this flying machine (without technical installation) is less than 20 marks, and it is also possible for any experienced model maker to complete the first flight within 24 hours of starting to build this model. The Stratos consists of just a few parts, and the flying weight is also extremely low, so that even harder landings remain without consequences.

Now for the start of construction: A styrofoam plate is divided into parts 1-9 according to the enclosed sketch on a scale of 1/10. Then the 88 mm wide opening for the fuse box is cut out of part 1 and then parts 2 and 3 using contact adhesive or epoxy..."

Hanno Prettner having fun! I wish to believe this fox hunting thing is a literal translation, would someone germanophonic provide meaning of the jargon? Very low flight, ground effect, obstacle avoidance (hopefully) and all that?

Hi Miguel, 'Fox hunting' means chasing others' streamers, and cutting them with your prop, while others do the same to you. Would 'combat' be a more appropriate translation?
Stefan - 04/04/2022
Translation engines also spit out "fox chasing" and "target flying", so maybe... combat?
RC Yeager - 04/04/2022
Thanks, it's clear now. So the fox has a chance to bite back.
Miguel - 04/04/2022
Slightly different from combat. Only the fox is towing a streamer and the other planes, the hounds, try to cut it off with their props. I think being the fox is the safest option. The hounds tend to have mid-airs all going for the one target.

* 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.
