Skybooster (oz6034)

About this Plan

Skybooster. 2m powered glider.

Quote: "Designed by Paved Bosak, this two meter powered glider makes an ideal way to get started. Designed for three function radio with a .10 - .15 size glow for power. Could be set up for electric also.

It is my belief that a powered glider type is an excellent choice for a 'Sunday Flier' sport type model. Its principal advantage is that the larger space required for a conventional glider with the necessary towline, winch, or high start launch system, is not needed. Simply fuel up the Skybooster, check your radio system, and fly. In fact, if a diesel engine is used to power the Skybooster, the only necessary accessory is your fuel bottle.

I decided to design or build such a model for sport flying, and also as a training aircraft for my son (who is beginning to take his first steps into the wonderful world of RC flying). I did not want to build a plain 'boxy' type model, but wanted to create something that would resemble a full size powered aircraft. The result was the Skybooster; a model that flies as you would hope and expect - slowly, quietly, and without any bad habits or tendencies.

Construction. It is recommended that all parts he fabricated prior to assembly. By first doing this, a 'kit' is created and the construction phase seems to proceed more rapidly. The construction of the Skybooster is quite simple and well within the capability range of all RC'ers except for an absolute beginner. Any modeler who has constructed a kit or two should not have any difficulty in building a Skybooster.

Wing: The wing is constructed directly over the plan sheet, as is the stabilator. There are five different types of wing ribs, with the locations dearly indicated on the plan sheet. When fabricating the wing ribs, it is recommended that the W4 ribs, of which 44 are required, be cut by first making two 3/32 plywood or 1/16 aluminum rib templates. Then sandwich ten or twelve 3/32 balsa sheet rib blanks between the templates, bolt everything together, and cut, notch, and sand the ribs to shape.

The wing panels are assembled by gluing the respective wing ribs to the spruce spars. The spruce spars should fit snugly into the wing rib notches. Cement the 3/16 square leading edge and 3/8 sheet trailing edge in place, along with the 3/32 sheet rib gussets. When dry, remove the wing panel structure from the building board and sand the leading and trailing edges to shape. See the typical wing cross section view to obtain the proper shape..."
