- Page 2 INTRODUCTION Congratulations and thank you for purchasing the Radiowave 3.2m Extra 330L or 300 ARF. Flying the Extra 330/300 is a very rewarding experience, as it should be for such an aerobatic model. With the aircraft control surfaces set for precision aerobatics, the aircraft will perform prescribed aerobatic patterns as used in IMAC (International Miniature Aerobatic Club) events exceptionally well.
- Page 3 ULTRACOTE COVERING AND CARE Humidity and temperature changes can cause the Ultracote covering to wrinkle during shipment and exposure to the sun at the flying field. This is normal and can be easily remedied. Wrinkles can be removed by using a heat gun and sealing iron. (with iron sock). When shrinking the Ultracote do small sections at a time.
- Page 4 Required Hardware Some hardware has been provided with this ARF. These are the hinges, the bolts and nuts required to mount the fiberglass cowl, the front hatch, and the plug in horizontal stabilizers. The wing panels have ¼- 20 blind nuts imbedded in the plywood wing roots for mounting the wings to the fuselage, but the bolts are not included.
- Page 5 Instruction for checking and Setting the Wing and Horizontal Stabilizer Incidence. Although the incidence is referenced to zero within +/-1/2 degree at the factory by laser, we have found for best aerobatic performance setting the wing and stabilizer incidence angles to zero degrees will give optimum performance.
- Page 6 Installation of the Control Surfaces 1. Trial fit the vertical fin onto the fuselage. Before the fin is glued in permanently make sure that it is perfectly straight. To do this, slide in the stab tube and center it by measuring both sides from the fuselage.

are 1 ¼” wide by 2 ½” long by 1/8 inch thick, and are located at the top and bottom of the elevator. Use the same procedure for marking the holes for control horn bolt as described for the aileron above. -
Page 8: Engine Installation
However, if you like, there are pre-cut holes in the rear of the fuselage for 4 standard size servos should you decide to install them in the rear for a push-pull system. Please be advised that installing the servos in the rear may result in a tail-heavy airplane and should be used for pilots more interested in 3D and freestyle aerobatics rather than precision aerobatics. - Page 9 5. Prior to mounting the engine we strongly suggest using a lightweight fiberglass or carbon fiber cloth with resin to provide extra strength to the firewall mounting. This can be done easily by laying the cloth across the firewall and down the sides of the engine box about 4 inches. 6.
- Page 10 Flying your Extra Initial Flight – We suggest a shake down flight with altitude. Check glide and stall characteristics. Please land and check control surfaces, hardware and engine for tightness. If you plan on using your aircraft for precision aerobatics please take the time to trim your aircraft properly.
