About this Plan

Aquarius. Control line team racer model. For 1/2A power.

Quote: "This 1/2A Team Racer was designed as a sturdy model which fly well in any weather. The engine is a standard Oliver Tiger-Cub, and best results have been obtained on the following fuel: Castrol M, 20%; Ether, 28%; Paraffin, 40-1/2%; Amyl Nitrate, 3-1/2%. This fuel will give easy starting and cool running for ab out 50 laps at over 80 mph.

After trying all sizes of props, we found that a 5-1/2 x 9-1/2 in gave the best performance. This is a Stant 6 x 10 in which has been thinned and trimmed to 5-1/2 in diameter. With the lower pitch props it is very difficult to obtain a consistent 45 laps.

Construction. Commence by shaping the engine bearers. Araldite and screw the metal engine mounts to the bearers after tapping the bolt holes. Cut out the wing and cement the spruce leading-edge in place. When thoroughly dry, shape the wing to section, add wingtip weight and install the controls, including push-rod. The engine should now be bolted to the bearers and the crutch cemented between the bearers. Now cement this assembly on to the wing, taking care to keep the bottom of the wing and the en gine mount parallel. After cementing the 1/8 in obechi plate on the bearers in front of the wing, assemble the undercarriage and Araldite in place with balsa block each side.

The tailplane can now be fitted and the controls connected, ensuring that the control system works freely. The tailskid should now be " Araldited " to the fuselage side and allowed to dry. Then the fuselage sides and bottom can be cemented on. Cut the fin from 1/8 in obechi and cement between 1/4 sq strips on the tailplane. Now shape the top block and hollow it out. Cement the rear half on and blank off the open end with 1/16 sheet balsa.

Assemble the cowling, leaving air space all round the engine. The balsa and plastic-wood wing and tail fairings can now be added. The cockpit should be built up, and covered with acetate sheet. Holes can now be made in the cowl and fuselage for the compression screw, fuel needle and tank-vent..."

* 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.
