Quote: "Can Do! John Toyer builds another Boddo Design. A few weeks ago at a local flying field David asked me if would be interested in building a free flight design he had recently conjured up knowing I enjoyed built up modelling.

The last DB model build in our workshop was a Tyro (oz6832) which we converted to two channel for aileron and elevator, powered by a Frog 150 diesel engine. Now luckily, when building models from plans, I usually make a wing rib template as I am sure most modellers do. Having worked for David for a time after leaving school, packing kits, I noticed most of the wings were constructed or contrived to a similar pattern and so it was of no surprise to find my template rom the Tyro was identical!

I also felt that the model was eminiscent of the DB Gringo free flight model which may bring back fond memories for some.

Tailplane and Fin: The tailplane is of the lifting type rather than just a flat plate stabiliser but is straightforward to build and no problems should be encountered. Start by cutting the ribs in pairs from 3/32 balsa (I used soft balsa for the ribs for lightness). When all the ribs have been cut lay down the leading edge of 3/16 x 3/8 medium balsa and the 3/16 balsa tips.

Next lay down the 3/16 rear spar the 3/16 x 3/4 trailing edge and add the 3/16 centre section. Fit all the ribs and top spar of 3/16 x 1/4 and slightly taper top spars to tips.

When dry, lift from the board and lightly sand all over to section, after covering add the 3/16 sheet locating plug to the underside of the tailplane.

The fin (which has a Bowden influence) is very straightforward, consisting of 3/16 parts built over the plan. Some thin tin hinges will be required for the trim tab and once again lightly sand to section.

Wings: Now this is where my previously cut template from the Tyro came into its own. The method of rib cutting I prefer when possible is to cut a stack of blanks, tape them together, use the template to mark the top rib and then use my band saw to, do the rest, which generally produces a nice set of wing ribs. The ribs were cut out of 3/32 balsa as shown on the plan. The bottom trailing edge is pinned down and the 3/16 bottom spars placed on the plan using 2 or 3 ribs to line them up, pinning when square and adding the ribs.

The wing tips should be cut from 3/16 sheet, built flat on the plan but not glued into position just yet. Add the 3/16 square leading edge and lift the tip slightly to meet it. Now glue into place the top 3/16 square spar and add the 3/16 gussets at the wing tip..."

* 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.


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.
