Marquart Charger (oz15249)

About this Plan

Marquart Charger. Peanut scale rubber model biplane. Wingspan 13 in.

Quote: "Gee Bee replica builder Ed Marquart designed this pretty bipe in 1967, has been winning at EAA fly-ins ever since. A good-flying Peanut. Marquart MA-5 Charger, by Don Butman.

If it's got two wings it has to be good! Well, this probably wasn't in Ed Marquart's mind when he designed the MA-5 Charger, but he came up with a winner nonetheless. Ed's Charger was 95% complete when Oscar Tombolato flew his Charger for the first time. Oscar started construction in 1967, completed it early in 1971, and won EAA's Big Event at Oshkosh, Wisconsin in August 1971.

The Charger has since proven itself to be a winner wherever it has been shown. It has a 24-foot wingspan and an overall length of 20 feet, with a 160-hp Lycom-ing engine turning an Aeromatic prop.

Construction of the model is typical sticks n' pieces, with only a couple of exceptions. The wing tips and vertical and horizontal stab outlines are made from laminated 1/32 x 1/16 pieces formed around cardboard outlines. The wheel-pant/landing gear strut assembly can be made from blocks or vacuum formed using .015 sheet plastic. This forming method works very well (with practice!) and produces a strong and light as-sembly.

The model is covered with yellow tissue lightly shrunk with water, followed with a couple of coats of THIN nitrate clear dope. The striping was done using a Rapidograph drafting pen, but any good felt-tip pen can be used.

A 12-inch loop of 1/8 flat rubber has been used and gives flights of 25 to 30 seconds. No adjustments were required with the incidences set up as shown on the plans. Good flying!""
