About this Plan
Chippertoo. Radio control sportster for .40 power and 4 functions.
Quote: "THIS DESIGN has been in my I mind, and in sketch form, as a logical follow-up to one of my earlier models Chipperoo (oz9456) for some time and, finding myself with some of that rare commodity, spare time, I drew up the plans and started construction. In a couple of weeks, there she was, ready for the first flight. The HP.40 provides plenty of power, and I suspect that a good .29 or .35 would be adequate if you can keep the weight down to that of the prototype.
So, if you like your models docile and attractive, read on.
Contruction: Make up the four wing skins from 1/16in medium grade sheet balsa and when the adhesive is dry, sand the face side ready for attaching to the wing structure.
Cut the ribs from 1/16 and 1/8 sheet as indicated, adding the ply reinforcings with cut-outs to suit the undercarriage mounting blocks; fit the lower rear spar over the plan and glue the ribs in position. Note that the wing is built with the trailing edge flat on the board, packing up the ribs for support as necessary..."

* 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.
