About this Plan

Binkie. Free flight power duration model. Elfin 1.8cc shown. This is a modern redrawn plan in PDFvector format.

Quote: "BINKIE Mk1 was built in 1948 for the Belfast MFC's first power ratio competition and with a Mk. 1 Mills in front it finished 2nd, averaging 6.2 : 1. A larger Elfin powered version was built for the same comp. in 1949 and without any trimming flights whatsoever it won, averaging 7 : 1 in a half gale. Gipsy Drew, captain of the Irish Wakefield team, flew an identical model into 4th place in the International power ratio event at Cranfield. Binkie III, which was the same as Mk. IV except for the u/c and cowling and a few structural points, was flown at the B.M.F.C. annual Rally and finished first with 229 secs. on 17 secs. engine run.

Mk. IV was flown with the dope hardly dry and in a half gale on Sunday, June 4th, 1949, and with two o.o.s. flights clocked 15.76 : 1 to finish 4th in the MACI Northern Area Rally.

Trimmed to the maximum in really good weather conditions Binkie was proved to be capable of 41 mins, and on 18-20 sec. motor runs.

Construction. Cut out fuse sides and F2 to F5. Lay one side flat on plan and fix formers in positions shown. When dry fix other fuselage side and after chamfering off the insides at the tail end sandwich fin in position.

Cement in 1/8 sq spacers and tailplane support. Securely bind and cement u/c to F3 and slot in underbelly keel. Bolt engine to F2 and fit F1 to mainbearing housing. Form cowl with planks of 3/32 x 1/4 balsa. Fit dowels etc and cover with rag tissue or Modelspan.

Assemble both wing spars to conform with dihedral as shown and assemble wings in usual manner, one panel at a time..."

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
