About this Plan

Bumblebug. Designed by Les Howell Bumblebug is a CL stunter for 1.5cc motor. July 1951 Aeromodeller. This is a modern redrawn plan in PDFvector format.

Quote: "POPULARITY of the smaller 1.5 cc diesels now exceeds that for any other engine capacity. This fully acrobatic and very slick stunter is especially designed for either the Allbon Javelin or Elfin 1.49, and will go through every manoeuvre in the stunt schedule at almost 60 mph. Built with a fixed wing, its 28 inch span is not over-large for transport, and the rigid structure provides a tough job that will withstand the occasional prang. Why not make one for your 1.5, and fly it next week-end?

Construction. Wing. Build up ribs on 1/8 square spars dry. Add trailing edge sheets making sure structure does not twist in the process. Glue spars. Glue one leading edge sheet to respective spar and leave to dry. When dry, glue to ribs. Repeat for other sheet. One or other of sheets to be chamfered to make good fit at leading edge.

Add control system and complete centre-section sheeting. Add tips and paper tube lead outs. Form attachment ends or lead out wires. Sand smooth. Add tip weight securely.

Fuselage. Make bulkhead and bearer assembly first. Pre-cement fuse sides to this assembly, making sure (by pre-determined line on fuse side) that thrust line is parallel to wing.

Tailplane and Elevator. Make up as a complete assembly - sanded, covered, doped and hinged. Now assemble fuselage as such: wing; and tail /elevator assembly, making sure all components are square and true in all views..."

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.
