Tyke (oz2975)

About this Plan

The Tyke. Leeds Club Wakefield. Wakefield rubber contest model. This is a low resolution plan. I am rather hoping someone can submit a higher quality scan of this one.

Quote: "This design was produced by a sub-committee of the Leeds MFC, the object being to plan a simple, easy to make and easy to fly Wakefield. The design had to be suitable for juniors who had only made two or three models, and also for the grey-beards who had been model flying since the bamboo and oiled silk days.

Accordingly we made it as simple as possible - just the bare essentials of a Wakefield, in fact - and incorporated a choice of wing sections. There is Clark Y for those who don't like covering under-cambered wings, and RAF 32 for those who do, if any. The rest is plain sailing. Even the propeller is about as simple as it could be; and when you have finished you have got a model to Wakefield rules which will climb high enough to compete with the best in normal daytime conditions.

Performance is really up to the builder, first of all in making the model, and later in trimming it. During construction, keep the weight down by using good quality wood, and only using hard wood where you think it is really necessary. The weight of the whole model, minus rubber, should in no case exceed 4-1/2 oz, and with a little care you should get it below 4 oz.

Fuselage. Build the two sides flat on the plan. Assemble them with the aid of the two formers, using the flat portion on the fuselage top to keep the structure true. Make up the undercarriage box, bind it tightly with thread, and rub cement into the binding. Use ample cement on the gussets which hold the box to the longerons. The undercarriage and wheels are self-explanatory on the plan.

Propeller and Noseblock. Lay out the block from five layers of 18 in long quarter inch sheet, 1 in wide, as shown on the plan. It is an advantage to drill each layer before assembly, and then to assemble them on a piece of wire protruding vertically from the building board. The centre hole for the bush is then automatically true.

Leave the block to dry for 24 hours, then carve and sand. Cut away about half the block thickness at the back of the hub to reduce weight and drag there. Make the noseblock from four layers of 1/4 in sheet, with a rectangle made up from 3/16 square to fit into the fuselage nose. Ensure that the bush is true, then carve and sand to shape..."

Update 29/10/2015: Replaced this plan with a redrawn copy, much clearer, thanks to MBright.

Quote: "Hi Steve, this is my first submission to Outerzone. Please find attached redrawn plan using of The Tyke, plan ID 2975, using QCAD. I found the original very difficult to read and had to make a number of intelligent guesses during the drawing process, therefore, I would strongly advise anyone building from this plan to check everything very carefully before assembly. Regards. P.S. Outerzone is a wonderful project which has brought back many memories of my early modelling day. Many thanks."

Update 19/08/2018: added article, thanks to RFJ.
