About this Plan
Hoverking. Free flight slope soarer model.
Quote: "THERE is no reason why Slope Soaring should be limited to aeromods in the few highlands we have in these Isles or to our counterparts in the Alps of Europe. Hoverking is good on any hillock or slope when the wind is favourable.
On its second outing Pete tells us: 'Launched from a 100 ft hill, the model remained into wind for 2 minutes, soaring beautifully before turning downwind.' Which emphasises that this design incorporates the prime essential of a slope soarer, the ability to hang nose into wind without losing height.
Those who have yet to see a slope soarer rise and fall with each change of wind current, have thrills in store. With the sole exception of the flat Fenlands and eastern areas in Lincolnshire, it is possible to find a soaring site within easy distance of each town in the British Isles.
Hoverking also lends itself well to a powered sailplane. A small diesel or gloplug motor can be mounted on a pylon high enough to allow propeller clearance, and positioned between the nose and wing leading edge.
Constructional Notes. Fuselage: Select hard 1/4 x 1/4 in balsa for the longerons and spacers. Pin the longerons over the side view, joining them with scarf joints at least 1 in long. Cut and cement all the spacers except those at the wing position, which are added after the 1/4 in sheet has been slotted for the wing tongues and fixed. Now cut the 1/4 in sheet for the nose box and fix in place. Repeat the operation for the second side, building directly over the first side. Remove both sides together and sand the outlines before separating.
Pin the sides upright over the top view on the plan. Cut all the spacers and fit those at the wing position first. The 1/4 in sheet for the nose box is cemented into place as the fuselage is drawn together. Use rubber bands to hold in place until the cement is dry. Similarly, the rear of the fuselage is brought together and the remaining spacers are added, together with the sheet which supports the fin outline. The wing tongues should be cut from 3/16 in. plywood and cemented firmly in position..."

* 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.
