Swinger II (oz9459)

About this Plan

Swinger 2. Radio control pattern model.

Quote: "QUITE recently, Terry Cooper and I have made modifications which we consider are a worthwhile improvement to the flying performance of the Swinger. Appropriately, this has been labelled the Mk II version.

No doubt you have read the previous feature on the Mk I Swinger in the November 1968 issue of RM, and you will see that this design formed part of a development to find a model that would do the present FAI schedule. If you have followed the results of the competitions during the past season, you will undoubtedly agree the design has something to offer.

Having studied various aspects of the model, it was decided that no major changes were required. You will appreciate that, whilst changing the design to suit one manoeuvre, the effect could be detrimental to another; it's all a matter of compromise.

Referring to the plan, you will see that the fuselage has a leaner appearance; this has been achieved by raising the chord line 1/2in and consequently entailed removing 1/2in from the depth of the entire length of the fuselage. This has had the effect of improving the roll manoeuvres - the model now rotates on a more axial plane and consequently requires less up and down correction. This modification has also had the effect of lightening the rear end and maintaining the favoured forward CG position.

Additionally we threw in a bit more nose moment, 1/2in to be exact. This appears in front of the LE wing fixing bulkhead. It gives the model a rather more of a pointer effect - and we also found the inside and outside loops were improved..."
