About this Plan
Chunky. Free flight power model for .049cc motors.
Quote: "Cheap to build! Easy to fly! Perfect for the novice! An Aeromodeller staff design for .5 to .8 cc.
THE NEW .049 cu. in. engines are rapidly becoming popular with newcomers to our hobby, and many such novices have requested that we provide them with a special design to suit the new power units.
We realise that for real contest performance, any .049 powered model should weigh around 4-5 ounces, have light wings, and be trimmed for a near vertical climb. Let us state right at the beginning that Chunky is not of such a breed. Here we have a 'toughie', easy to build very easy to fly, and still having good performance. We checked the prototype with the weakest of the .049's (no names - no pack drill!) and at a total weight of 8 ounces. By selecting such extremes we know that Chunky will fly well. The careful modeller can whittle the weight down to 6 oz. through use of medium/soft balsa and a 'hot' motor will give best performances.
One must first study the plan thoroughly, with reference to these instructions to completely understand the method and sequence of construction. The model has been designed to be built on a standard schoolboy budget, so if you want to keep cost to a minimum follow the parts layout given on the plan.
Fuselage sides F1, F2, are traced from the drawing using a straight steel edge and soft pencil. The tracing is turned over and placed on the 3/32 in sheet and with a hard pencil this time, the outlines are followed, reproducing the fuselage sides on the wood. F1 and F2 are now cut out, again using the straight edge. Engine bearers should be cut to length from 5/16 x 1/4 in hardwood.
The right hand fuselage side is pinned over the plan and the bearers double cemented over this in their angled down position. Two layers of 1/8 in sheet fill in the space between bearers, the outline for these being traced from the plan. Note that the wood grain here must be vertical. Once cemented the whole should be held in place with pins until quite dry..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
