Little Lindy (oz10186)

About this Plan

Little Lindy. Free flight 1/2A power model. Wingspan 52in, wing area 290 sq in.

Quote: "Larry's Little Lindy, by Larry Conover. Here's long-awaited miniaturized version of LC's internationally famous 'Lucky Lindy' free flight; this takes .049 Half-A power, 051 for Class A.

The highly competitive FAI free flight classes have developed models of above average performance. Not too long ago, four or five minutes on a 20 second engine run (in really dead air) was considered hot stuff in the AMA categories, However, FAI Power models of that day would do six to seven minutes on 20 seconds. Hoping to take advantage of many lessons learned in international meets, Little Lindy was scaled down from its big brother. It has many design features from the FAI Lucky Lindy (oz8854), which competed on four US Power teams. This 1/2A version is a pleasure to fly, but has one fault. It will keep you busy building trophy cases.

Design features: The size is right - big enough to handle the 20,000rpm scorcher, but no overload for average engines. Not a lightweight, built to last for more than a season. The airfoil: A 10% Lindy section that has proven itself through many years of contest flying. Guidance system: A simple fixed control set-up using twin tip fins on stab, and a central power-rudder. Structure: Warp resist-ant wing with full depth center spar, for windy weather flying.

Construction: Your ability to select the right type of wood for each part of the model, marks you as either a 'fugitive from the plastics', or a 'USA team member type'. Take care.

The wing has hardest and strongest wood in the center section. Should be gradually lighter toward the tips. Cut out your wing ribs carefully. This section must have the sharp leading edge and the turbulator spars as shown. To keep wing true build it on a flat board, make joint ribs from hard balsa, form tapered wing ribs (W-6) with sanding block after assembly..."
