Eee-Z-Fli Pylonair (oz12220)

About this Plan

Eee-Z-Fli Pylonair. Radio control sport model.

Quote: "The latest creation to spring from the author's Eee-Z-Fli drawing board, a racer-like sportster for four channels and .25-.30 power.

The Pylonair is an easy-to-build, real fun airplane. It looks great (my opinion), is an out-standing flier and has a unique 'see through' feature that makes it a useful teaching aid to new and prospective entries into the RC fraternity, as well as interested spectators at mall shows and other public showings.

How often do you hear questions about how the radio works? What makes the controls move? What are servos? Where is the gas tank? Do you have a battery and a radio receiver, etc? The see through feature of the Pylonair answers all of these questions literally at a glance. The entire top quarter, from the firewall back to the canopy, may be covered in clear or tinted plastic, the fuselage diameter being such that a two-liter soda bottle fits like a glove! Turn on the radio, operate the controls, and all those many questions are answered. Seeing is the best teaching medium you can find!

If you prefer the big-engine, long-nose racer look, paint the cover to match or, better yet, make a second cover of soft aluminum for flying and keep the plastic see through for show. The Pylonair is fast, quite aerobatic and still retains the 'polite' takeoff and landing characteristics common to the Eee-Z-Fli line of aircraft.

GENERAL NOTES: As with any building project, assembly goes faster if all the parts are available as you need them, so spend an evening cutting out parts. As for equipment, the plans and building instructions denote the prod-ucts used by the writer. Building methods may be varied at the builder's discretion, but radical departure from the plans and accompanying instructions is not recommended. The type of wing construction shown is very rigid and resists corrective warping, so build it flat.

Work the plans and the instructions together; something unclear in one may be defined in the other. The entire construction of the Pylonair is pretty straightforward and should not present any difficult areas.

TAIL SURFACES All tail surfaces are constructed of medium balsa. The elevators are joined with a hardwood dowel. Align the elevators with the stabilizer and mark and cut the hinge slots. Cement the hinges into the stabilizer only. Do the same with the fin and rudder. The fin rests on the top of the stabilizer, so it is best to wait until the fuselage is completed to fit the dorsal. Sand all surfaces and put aside for final fit prior to covering.

FUSELAGE: Make the ES-1 fuselage sides. Install doublers D1 and D2, leaving a space for the firewall (B1) and former B2. Be sure to make a right and left side! Now cement B2 in the slot between triangular strips in the corners.

When the cement is dry, pull the fuselage aft ends together, assure they are square, secure them with clothespins and cement the joint. Former B4 can be installed at this time also. Exercise care with the alignment as this is where bananas are born!

Starting at B1 (firewall), attach all the F series formers. Note that F2 and F4 mount back-to-back with the stringer notches cut in F4. After the stringers are installed, make and install support shims between the stringers and the fuselage sides at station F7. The fore and aft wing supports (of 3/16-inch plywood) can now be epoxied in place, along with their triangular supports..."
