Electra-Fli (oz8904)
About this Plan
Electra-Fli. Radio control sport model for electric power with Astro-10 motor system. Wing area 335 sq in.
Design by Bob Boucher and Dave Shadel. Inking by Charles Jackson.
Quote: "Silent aerobatics are fun with this two-channel, electric-powered model. Motor/battery system is rechargeable at the field in just 15 minutes.
The Electra-Fli was designed while I was searching for a suitable sport-type aircraft for the Astro 10 electric propulsion unit manufactured by Astro Flight Inc, of Los Angeles.
Several kit designs were modified to accept this system and of these, the Midwest Cardinal and Goldberg Ranger 42 proved the best. They were docile in flight and were good trainers, but it was believed that a lightweight, all-balsa design with similar dimensions would perform even better.
The first original designs resembled the Spirit of St Louis Electric Pylon Racer flown by Bob Boucher at the 1972 MATS Show, but with larger constant chord wings and an increase in the tail area. We have flown several variations over the past few months, and are quite pleased with their ability.
This ship will ROG from smooth sur-faces in 50 to 60 ft. It will perform bar-rel rolls, snap rolls, inside loops, spins and inverted flight. If you're interested in a fun-type ship which is easy to build and fly, quiet, and doesn't spew out greasy kid stuff, give electric flying a try.
Construction: The Electra-Fli can be built and ready for covering in one day.
Fuselage: The fuselage is an all-balsa box with only three formers. The motor tube can be made from a rolled balsa or cardboard tube, whichever you prefer. It must be a snug fit, since no bolts are used to secure the motor. Remember, electrics have no vibration and will not tear out of the mount as glow engines have been known to do.
Wing: The wing is of the fully sheeted, constant chord variety, with 1/16 balsa top and bottom skins, 3/32 ribs and a 1/4 sq leading edge..."

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.
