Anymouse - Unusual 62in span 3-function slope soarer for racing and aerobatics.
Quote: - "When I first became interested in slope soaring, I looked over the published designs but could not find what I felt was a good looking model. This only goes to show that modellers have very individual tastes, of course. I therefore bought a kit for a fairly straightforward non-aerobatic glider on which to learn the basic skills of slope soaring. This model proved quite successful but, being non-aerobatic, I soon became bored just stooging to and fro along the slope, especially when the lift was good; after all, I had been flying acrobatic power models for the previous twelve months or so. Having learnt the basics of slope soaring, I decided that an acrobatic model would be a good thing to keep me amused and presented more of a challenge.
I decided therefore to design my own model, working on the well-tried aeromodelling rule that if it looks right, it should fly. There are those, of course, who question the 'looks right' bit, but this is tied up with basic requirements as well as aesthetics. It had to have a large wing area to help cope with occasional marginal lift conditions, but not too large a span or it wouldn't go in my car - not to mention the question of roll-rate - so it had to have a large chord. It also had to have good penetration, as the wind speeds in Cornwall rarely drop below 15 knots and at times are very much more, so I decided on a 9 percent thickness/chord ratio. Also, as it was to be aerobatic, the aerofoil section had to be symmetrical.
I chose a high wing position in order to keep the ailerons as far as possible from the ground on landings, as some Cornish sites are rather on the rough side. The high tail-plane was used for the same reason. I have a preference for slim fuselages as they do improve penetration - and the long nose was designed to increase the moment arm to the cg and therefore reduce the weight necessary to get this in the correct position. This, in turn, helps to keep the overall weight low, and I was aiming for around 2-1/2lb flying weight."

* 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.
