Isaacs Fury (oz16293)

About this Plan

Isaacs Fury. Peanut scale model for rubber power.

Quote: "Isaac's Fury. We have here a combination of a neat prototype and a nifty model that biplane fans can't help but enjoy. If you appreciate the joys of Peanut Scale, put a little Fury into your life! By Gene Post.

IF EVER THERE WAS a biplane designed with the Rubber modeler in mind, it must have been John Isaac's homebuilt Fury. It has all the features we like to see in a design to be modeled - adequate nose moment length, long landing gear to accommodate a large prop, large tail surfaces, and generous dihedral. It has simple markings and color scheme. which arc easily reproduced on the model.

There are two excellent sources for pictures, scale drawings, and other authentication information. The 1965 Air Progress Aircraft Annual has good scale drawings, a cutaway isometric drawing, and several pictures. The 1965 January issue of Aero Modeller (English) contains an article with the same drawings but few pictures, however it features a colored picture of the Fury on the cover.

As far as I know the Fury has been modeled only twice, once as an RC ship a few years ago. More recently Jack McGillivray took third place in Indoor Peanut Scale with the Fury at the 1976 Nationals. His model could do 90 seconds (reported in NFFS Digest), a very respectable showing among all the Laceys and other 'ideal' Peanut designs. As best l can determine, no FF plans have been published of the Fury up to now, which is a surprise to me. The more I worked with this design, the more I became convinced it is an unusually good airplane for a Scale project. Scaling it to a Jumbo Rubber or Gas Free Flight is anticipated for future projects.

Construction: It builds up like most any other stick-and-tissue Peanut, and has no particularly difficult construction characteristics. Consequently. we won't bother with a step-by-step description. Only the points that may be somewhat unusual or specific to this design will be described.

The model was built for outdoor flying, and rather large balsa was used. If an indoor model is to be built, use smaller wood where feasible. The original model weighed 11 grams, including lead weight in then nose but excluding rubber..."
