Little Twister (oz8106)

About this Plan

Little Twister. Free flight power model. Atwood Wasp .049 shown.

Quote: "Prediction for 1951: This model will capture many first places, set numerous A/2 records.

Most of the flight adjustments are built into the Twister to make flying easy. A model with the wing and tail out of line that flies well is nothing unusual these days. It's a lot easier to make a model turn in the glide and under power by tilting the stab than by other adjustments. The proper amount of tail tilting must be determined for each model since a wing may have been warped a little to help or retard the turn. This shows up in the glide. A model that has a stalling turn will rarely spin under power. Instead it will climb well and then stall in the glide. This can be taken out with 'turn.' You can get the most out of your Twister with true surfaces, a tight turn in the glide and a little offset in the thrust (if the model doesn't climb in a definite pattern).

Start by building two fuselage sides. Cut out pylon, cement on wing platform. Add cross-pieces to sides, omitting those at top, right front. Cement pylon, in place. Add remainder of cross-pieces and fill-in sheet. Add fire-walls with landing gear in place. Fuel-proof this thoroughly. Cement stab platform in place with the wire parts; re-cement when dry.

Cut the wing ribs from 'C' stock balsa to keep them from warping. Shape leading edges and cut to length along with trailing edges. Lay these down first, cementing gussets, then the ribs in position. Use light balsa for the tips. Sand wing parts, then re-cement joints again to prevent warping. The stab is made the same as the wing. Cut the rudder to shape; sand leading and trailing edges. Cement the rudder in straight, as it does not turn the model but gives it directional stability..."
