About this Plan

Gambrinus. FAI competition model.

Quote: "EARLY IN 1968 your Editor sent me the plans of Hans Seelig's FAI power model requesting that an 'Anglicised' version be built. At the time it was intended to publish a normal building article and to offer full size plans in the usual way. Unfortunately it has not been found practical to do this, mainly because the hardware required is not commercially available, so it has now been decided to describe the unique covering methods used by Hans Seelig and to allow the reader to make up his own mind as to the usefulness of the ideas presented; hence the title of the article.

The model is covered almost entirely with glass fibre cloth and epoxy resin over an all sheet structure which results in tough, smooth long lasting model. Two weights of glass fibre cloth are used. The heavier cloth weighing 2-1/2 oz per square yard covers the fuselage, and the lightweight cloth weighing 1 oz per square yard is used on the mainplane and fin. Many epoxy resins are available and a list of those tried are given in the Table. All have been found successful but some are lighter than others so it might be advisable to experiment with available resins.

At this point it is assumed that the wing panels have been built and haiie been carefully preparedfor covering with the lightweight cloth. Before mixing up the resin and hardener in the exact proportions recommended by the manufacturer, cut a piece of cloth so that it will wrap round the entire panel and overlap at the trailing edge and at both ends. Now place the panel on a clean clean piece of PVC sheet and carefully uncover the top of the panel..."
