Quote: "Old Timer of the Month. Rambler. Designed by Gil Shurman. Drawn by Al Patterson. Text by Bill Northrop.

The Rambler was published in the September 1939 issue of Flying Aces. This article states that it was first flown at the Second Annual Quaker City Gas Model Airplane Association contest at Northeast Airport, Philadelphia, in September 1938, which may or may not qualify it as an Antique. Check with john 'Daddy Warbucks' Pond.

The wing features a flat center panel with sharply dihedralled tips, a configuration that has been proven time and time again to be excellent at thermal finding - and keeping. Worth thinking about for modern designs.

Adding a DT set-up should be a snap when you consider the way the tail surfaces are mounted. And once again, there is no indication, on the plans or in the text, as to location of the balance point. Considering the short nose and long tail moments, and the symmetrical stab, we'd suggest starting at 50%, or 6 inches back from the wing leading edge.

For R/C assist, the Rambler should be excellent for the 20 second engine run event, and for the increasingly popular precision time and spot event. The wing area of about 730 qualifies it for .29 glow engines, which, combined with its light weight, should make it a real performer."
