About this Plan

Hotchpotch. Radio control sport model for .10 - .15 power and 2 function radio.

Quote: "A lively 36 inch tiddler for .10-.15 power and two-function radio (ailerons and elevator) Hotchpotch, by Ken Murgatroyd.

LAST YEAR, while on holiday in in Devon, I heard about Woodbury Common which, as it happened, was only a few miles from where I was staying. Needless to say, it was not long before I went to survey the area and, on arrival, would have given almost anything to have had a model with me! The sight started me thinking. As the friends I go on holiday with are walking fanatics and I tag along like an obedient spaniel, it occurred to me that a small, diesel-powered model, which would take apart and fit into a confined space, would be the answer. Then we could all do our thing!

The result of all my cogitations was Hotchpotch which, as its name implies, is really a combination of numerous other designs before it. But with a difference. The difference is that, instead of being a trainer, as most of these types of machines are intended to be, the Hotchpotch is more of a 'hot cookie' intended for the flier with a fair amount of experience.

The main requirements I had considered to be necessary when drawing it up, were: not too big and thus easily transported; reason-ably inexpensive to build; aerobatic performance on two functions; economical to run.

Any glow engine of around .10 to .15 cu in capacity could be used, although I fitted an old Elfin 1.8 cc diesel to the prototype (brought out from retirement after 25 years!). This drove an 8 x 8 prop, cut down to 7-1/2 in. Using the diesel saved me having to carry that weighty starting accumulator, and the only items required to take with one (apart from the model) are the transmitter and a can of fuel.

CONSTRUCTION: As this type of model is mainly for the modeller who has built a few models before, I do not intend to go into detailed assembly methods, but rather to point out useful pieces of information. The plan gives all the necessary information for building, in any case.

Wing: The wing has a fully symmetrical section, using a full-depth spar for lightness and strength. A small amount of dihedral has been incorporated for appearance's sake, although I see no reason why this could not be left out, to cut your building time..."
