About this Plan

Timeta. Control line FAI Team Racer model.

Quote: "Going Racing? Why not try this highly developed model? FAI Class Team Racer TIMETA, by Derek Heaton and Malcolm Ross.

Malcolm Ross (left) the pitman, and Derek Heaton the pilot are a familiar sight in their blue track suits at every major event in the country, where they have a habit of performing rather well!

OUR TIMETA MODELS have been developed over the past five years and in this time we have experimented with a wide range of tanks to achieve maximum consistency, and have found that the simplest and most reliable has been the straight, single cell version - as drawn on the plan. The latest addition to this has been a fuel cut-off system (operated by down-elevator movement), and although this does not necessarily mean faster pit stops, it does allow the engine to be cut at the best possible point of the circle for consistent, quick stops - it also allows immediate adjustments to be made to the engine in the event of a poor run. A good example of this occurred during the 1970 World Championships when the engine began to harden up around the 84th lap mark. Derek immediately cut the motor enabling Malcolm to richen the needle, losing very little time - certainly less than otherwise would have been the case. The pressurised re-fueling system (based on a Volkswagen windscreen washer bottle) although not essential, does help and at least leaves the right hand free to catch the model! By using a cast aluminium engine mounting plate the heart of the system (engine/tank/cut-off) may be lifted in and out of the model without any trouble or risk of disturbance.

Construction is centred on choice of the pan. The designers can supply suitable pans, or else a commercial unit may be used, adapting the fuselage shape to suit. It is very important to fit the engine to the pan so that there is no 'rock' on the engine lugs this can be done with a sheet of emery paper on a flat surface ie surface plate or sheet of glass. Once the engine is seated squarely, drill and tap all the mounting holes. Using the pan as a tem-plate, drill the mounting holes in the beech bearers. Recess 6 BA mounting nuts into the underside of the bearers, and epoxy them in position.

Now bolt the pan to the bearers and mark them to suit the curves of the pan, as well as to fit snugly around the engine lugs and needle valve. Remove to carve and sand to shape. Once more refit the pan to the bearers, and add the 1/4 in balsa crutch followed by the 1/4 x 3/8 in spruce strengtheners... "
