About this Plan

Wee One. Diminutive control line stunt model for Cox .010 power.

Quote: "Here is a classy little stunt job that you can fly right in your back yard. Takes an .010 or .020 engine and minimum of material.

With wing flaps it is sensitive, so a small leverage on the control handle should be used. The model would fly very well without the flaps and much easier for the new modeller. A Cox TD .020 or Babe-Bee 020 would make a real nice flying model with a lot more power.

Start by cutting the wing ribs and spar from 1/16 sheet. The spar is one piece. Slide it through rib R-1. Make sure it is square when you glue it. Put R-2 ribs on ends of spars. Glue the 3/32 square leading edge and R-2 in place. Cut the wing trailing edge from 1/8 sheet and glue in place. Make sure that everything is lined up. Make a rib template and slice R ribs from 1/16 sheet. Trim and fit them in place. Add 1/16 sheet tips and tip braces. When everything is dry, sand smooth with sanding block.

Cut and fit the 1/16 plywood bellcrank mount. Bolt the two inch bellcrank, with the feadout wires, on the plywood mount and glue in place. Bend a push rod and install. Cut the flaps from 1/16 sheet. Make up the flap control horn and glue it on using a cloth strip reinforcement, fitting flaps to wing. Use silk or hinge-cloth, to hinge flaps to wing.

Cover the wing with tissue and give one thin coat of dope. Cut the tail parts from 1/16 sheet. Bend an elevator horn and glue on as you did with the flaps. Put on hinges and sand smooth.

The fuselage is built on the wing. Cut two sides from 1/32 sheet, Make the firewall and landing gear mount from 1/16" plywood. Sew the landing gear (bent from 1/16 wire) to F-2. Glue well. Locate and drill the motor mount holes. Use blind mounting nuts or epoxy the nuts on the back of motor mount. Slide the fuselage sides on to the wing. Make the fit as tight as you can..."

User comments

Hi Steve, I found the article to go with this plan on RCGroups. Actually a Google search provided the PDF and I couldn't get onto the thread from there but they offered the article. Because this design uses the .010 Cox engine, the smallest IC engine ever, the design remains relevant and we are working on a couple. Cheers,

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.
