Rocketeer (oz4161)

About this Plan

Rocketeer. A 36 inch rubber model.

Quote: "Rocketeer has an average duration of 2-1/2 minutes on 900 turns, and thought not an ultra lightweight, has caught thermals whenever they have been about. As may be seen, the model is simple in construction and yet employs most of those features considered desirable in a duration mode!. The lifting fuselage is built on Warren Girder lines which make for maximum strength at lowest weight.

The simple undercarriage plugs into paper tubes, while incidence of main wing and tailplane is built in. Wing ribs should be tackled carefully - properly made, they are stronger and lighter than cut-out ribs. To ensure that undercamber is built in, packing pieces must be inserted under the ribs when constructing the wing over the plan; leading and trailing edges are then fixed; mainspar and supporting pieces added and finally the upper capping strips put in place. The built-up prop conserves balsa stocks and makes a really practical unit - though there is no reason why a conventional type should not be employed with equal success if so desired.

Trimming is a little out of the ordinary, the right-hand wing tip having extra incidence which permits plenty of side thrust to enstire a steep spiral climb to the right. Contrary to general belief, this does not an adverse effect on the glide, which is exceptionally flat.

Total weight ready for flying is 4.85 oz. A final word of advice - an extra hour or two spent on such details as pre-cementing joints will result in a stronger, lighter and more efficient model."

Quote: "This Time to the June 1946 AEROMODELLER... a very nice looking rubber duration model, the ROCKETEER, by R.PARKER was next. It does two and a half minutes on 900 turns and is of simple lightweight construction. A D/T would be easy to arrange."
