Snark (oz9132)

About this Plan

Snark. RC aerobatic model for .35 to .40 power.

Quote: "FOR SOME TIME I had had it in mind to design a model that was not too cumbersome for transportation, simple to build, fast but docile, easy to fly - and that would handle well in gusty weather as well as in calm air. After sweating over the proverbial hot drawing board for several evenings, I came up with something that satisfied my aesthetic sense - and looked as though it might do the other things as well. Here was Snark.

My 'design' technique is not to use actual drawing paper - or even wall paper - but to delineate the main profiles, and so on, directly onto the building board. (After three models, believe me, life starts becoming complicated - trying to follow and decipher the various lines!)

Snark is quite light, at around 4-1/2 lb and a .40 size engine will easily pull it through manoeuvres that require brute power, such as vertical eights, four point vertical rolls, and the like. The three prototypes built to date will actually climb in knife edge, from take off!

My OS .40P powered prototype has flown regularly for the past two years and has been joined, in recent months, by an HP .40-powered version, built by Mike Young (of Model World, Camberley), and a well built OS .40P type constructed by my good friend Bob Struder - who translated my drawing board into a meaningful plan, with the aid of a mammoth pair of calipers and some actual measurements from the prototype.

On Mike's model, which is fitted with the heavier motor, the fuselage has been increased in width at former B-B, to accommodate three servos side by side, and thicker decking used aft of the cockpit to achieve the correct CG position..."
