So, make sure that the lip is not damaged, and that the aileron slides under this lip perfectly. It will NOT lock at any time, as long as the lip is not damaged. If damage occurs to the lip, you can cut off 2-3 mm, but you should NEVER need to cut off more than this.
- Page 11 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com The Stabilisers: The stab parts are also vacuum bagged sandwiched. The rudder and elevator control surfaces are hinged with 4mm Ø tubes, fitted through phenolic hinge bearing plates which are installed during manufacture for perfect alignment.
- Page 12 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com The ‘Paint Job’ Occasionally customers notice certain problem areas with composite parts. But the question is: Are these real problems, or are they just a misunderstood sign of high-tech construction, proving the high-end composite technology? Seams: ALL composite parts have seams.
- Page 13 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com jobs is unique. In a ‘positive’ paint job some effects can never be done. Just think about the shadows, peel backs, highlights, and 3D effects - and all with a perfectly flat and uniform surface for optimum airflow and aerodynamics.

Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com Building Instructions General Tips: We recommend that you follow the order of construction shown in this manual for the fuselage, as it makes access to everything easier and saves time in the end. The wings and stabs can be done at almost any point, and only need servos installing anyway, as we have already installed all the control-surface horns for you at the factory. - Page 17 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com The outer 2 holes are 33mm(1 5/16”) from the bend, and the inner hole is 127mm (2 5/16”) from the bend. Note that they are not equally position either side of the centreline. The dimensions of 28mm and 8mm are measured from the front of the carbon landing gear leg.

Sand the inside surface of both side (horizontal) flanges to...
- Page 20 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com make sure that you don’t accidentally glue any of the bolts to the cowling or into the blind nuts! Space the bolts about 125mm (5”) apart, so that the lowest 2 bolts will be about 35mm from the edges off the square cutout in the bottom of the cowling, which retains it properly.

- Page 25 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com The rudder tray is supported on the 2 carbon-balsa formers supplied, and it’s exact position is your choice. However, the back former is usually installed vertically in line with the rear wing dowels, as seen here. Notch both ends of the rud- der tray to fit into the slots in the formers (photo right).
- Page 26 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com The last job is to connect the back servo to the rudder horns with the cables supplied. Cut the 2 slots for the cables to exit the fuselage about 3mm high and 40mm long.
- Page 27 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com Wings Finished in 4 - 5 hours The wings are 95% finished at the factory, and have already been installed on your fuselage to check the alignment. Even the dual phenolic aileron control surface horns have been installed for you.
- Page 28 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com Finally secure the phenolic arms to the servo discs using at least 2 small sheetmetal screws (2.2Ø x 10mm) in each. Make up the linkage between the 2 servos exactly as shown in the photo (right), using the 60mm long M3 all-thread, 2 nuts and 2 x M3 clevises.
- Page 29 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com You have 2 choices for servo installation; you can make a very long X-head screwdriver and insert it from the wing root, which is quite tricky but neat - or you can cut a servo hatch in the bottom of the wing surface.
- Page 30 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com requires about 3 - 3.5° sidethrust, and nominally 0° down- thrust. However, due to the mould joining process it is pos- sible that the downthrust can be off by 1/2° or so, but this can be checked easily by setting the wing at 0°...
- Page 31 Composite-ARF Extra 330L (2.3m span) techsupport@composite-arf.com Finally glue the 4 blind nuts to the inside of the firewall and fix in place with a little 30 minute epoxy. Adjustments to sidethrust after the first flights, if needed, can be made by adding or removing washers between the back of the engine mount and the firewall.
- Page 32 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com The twin mini-pipes seat on a steel strap (supplied with a template for bending), and are held in place with 2 springs. The springs are hooked over three M3 bolts that are screwed into 2.5mm Ø holes drilled in the 3 small plywood blocks that are securely glued to the front of this bulkhead.

With the R/C installation described here and this motor/mini-pipe set-up, you should not need any additional ballast in the nose to obtain the correct ‘Centre of Gravity’...
- Page 37 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com Making up the proper extension cables and connectors is only a little work, if you are proficient with a small soldering- iron, and makes assembly of the model at the airfield very quick and easy! Once all wires are soldered to the gold- plated pins, fit a short length of heat-shrink tube over each one.
- Page 38 Composite-ARF SuperXtra 330L (3.1m span) techsupport@composite-arf.com Final check Now check that you have fixed all components securely. Keep in mind that all the components inside the aircraft are loaded with the same G’s as the wing and the wing spar during aerobatic manoeuvres.
