Summer of Free-Flight

My “Summer of Free-Flight” has been a lot of fun! It’s been a learning experience, not always smooth going, but always fun! I’ve built and flown a few really fun balsa wood stick and tissue paper airplanes this summer.  The latest plane added to my fleet of planes is Rob Peck’s classic design, the Prairie Bird.

A friend recommended I build the Prairie Bird because of its reputation as a great flyer. He was correct; more on that later. I searched around on the internet and downloaded the plan. The plan was formatted to print nicely on 11″x17″ paper – so I uploaded the file to Staples and had them print me a few on some quite nice card stock. I believe five copies cost me under $3 total. I pinned the plan to my building board, covered it with Saran Wrap and got to work.

I really took my time on this project making certain everything was as perfect as could be. The straightforward design of the plane made it easy to construct a straight and square fuselage. I practically glued the cross-braces one at a time and waited for the glue to set before I adding the next one.

Adding tissue paper was a snap because there isn’t too many compound angles and curves to the parts. The tissue on everything except the rudder and stabilizer was shrunk with 50/50 water/alcohol mixture. Following the shrinking I added a three coats of 50/50 SIG Lite-Coat/Thinner. The windshield is made with clear plastic from a salad container. I used plastic Peck wheels, a Peck Nylon Bearing and Peck propeller. The propeller was balanced by gently sanding away material until an even balance was achieved (a lot more sanding than I expected).

My test flights were a great success. At first I was flying with approximately 300 turns on the motor, eventually increasing to about 600. Many more turns are possible, but I didn’t have a helper or a stooge to help me stretch wind the motor. I didn’t want to press my luck.

The thrill that is achieved from flying these little beauties is beyond words. The careful work and attention is forgotten – and happiness consumes me when they take to the air, and when they land where they can be easily retrieved.
