About this Plan
Excelsus. Radio control towline glider model. Wingspan 1700mm, for 2 channel radio.
Quote: "Inexpensive R/C equipment, which is now becoming readily available at amazingly low prices from retailers here in UK, now means that thousands of aeromodellers are discovering for the first time that they too can now afford to join in the fun of radio controlled flying. There can be no easier way of getting started, nor a safer type of model to learn the basics of control, than the rudder and elevator, 2 channel controlled R/C glider.
Excelsus is such a model, and the average free flighter or control line enthusiast amongst our readership will have no problem either with the straightforward construction or the simplicity of trimming out the model. Sensible design which is economic on building materials means that you can literally start from scratch, purchase brand new P/C equipment and all the wood required to build our Free Plan - all for under £40! Need we say more?
Excelsus is a two channel soarer capable of superb performance in a light breeze or on a moderately windy day. It is economical and easy to build from standard 900mm length sheets of balsa. The low wing loading, approximately 15gm per cm sq, enables the model to keep flying when most others are grounded through lack of lift and yet it can still battle its way around in 25 kmph plus winds, penetrating thanks to its relatively thin and fast flying wing aerofoil section. Lightly loaded soarers can be flown from shallow and otherwise less suitable slopes and the small flight pattern obtainable with this 1700mm wing span model enables landings to be made on the tiniest of grass patches.
The model embodies the most desirable features of a series of similar designs built and flown over the past two years. The construction of the airframe, whilst employing traditional strip, rib and glue methods, should offer few difficulties even for the tyro to the art. Only sheet balsa need be purchased as all the strip wood required can be cut from such stock using a very sharp, stiff blade and a 900mm straight edge..."

User commentsExcelsus is a nice model designed by Bryan Miller [more pics 003-005]. Not heavyweight (360g). I had difficulty getting the model on its first flight out of the thermals. A good construction and highly recommended!

* 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.
