About this Plan

Parakeet. Radio control sport biplane model, for .15 to .25 power. Also kitted by Tidewater Hobby.

Quote: "Although simple to build and set up, this little bipe offers realistic appearance and top-notch performance. Parakeet, by Dave Robelen.

Known for its simple construction, great three channel RC performance and sporty, realistic appearance, my popular sport-flying Pronto (oz1740) captures the very essence of fun. The design has long been a favourite of mine, so when fellow modeller Chuck Cusick challenged me to convert it into a biplane, I couldn't resist.

I didn't want to lose the fun in the midst of the modifications, so cost and simplicity became important considerations, I've used stock sizes of balsa (3 in wide x 36 in long), and all of the major parts can be laid out and cut from these or similar stock material sizes.

Three-channel control is totally adequate for lively aerobatics, and it greatly simplifies overall construction, saves weight and, in most cases, even assures a spare servo. Of course the parts count should be kept to a minimum for easy building.

Some modelers have created a 'Pronto Biplane' by simply adding another wing on top of some struts clamped onto the fuselage sides. My own approach was to use the same concepts that the successful Pronto employs, but to start from scratch with a biplane layout. My choice of model size was strongly influenced by the available engines. Experience has shown that those in the .15 to .25 group run extremely well and give a staisfactory flight time on only four ounces of fuel. This range of engines gives me excellent results with a model weight from 2-1/2 to 3 lb, fuelled and ready for flight.

The Parakeet airfoil is takes directly from the earlier Pronto design in which good speed range and excellent stall behaviour were the main considerations..."

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.
