Accessories

Here is a list of the things you may need to get your Composite-ARF Extra 330L in the air. Some
of them are mandatory, some of them can be chosen by you.  What we list here are highly 
recommended parts, and have been thoroughly tested. 

1. 

Power servos (min. 12 required). We recommend JR8511/8611’s for the ailerons, and 
either JR/Graupner 8411 or 8511/8611 for the elevators and rudder. 

2. 

Throttle servo (1) Any standard servo will do (eg: JR/Graupner 4041)

3. 

Aluminium Spinner 125 mm dia (5”), eg: Tru-Turn.

4. 

Main wheels 120 - 125 mm (4.5 - 5").  Kavan Light or Dubro wheels are recommended.

5. 

Engine DA-150. This is the recommended engine for your Extra 330L. The instructions 
refer to that engine several times, but you could use any other 50cc engine.

6. 

Mini-Pipe Muffler Set. (Consists of 2 cannisters, 2 aluminium headers, 2 Teflon couplers,
4 spring clamps, and mounting hardware).

7. 

Standard exhaust muffler. (optional, if noise is not a problem at your field)

8. 

High quality heavy-duty servo extension cables, with gold connectors. High quality
receiver and ignition switches, ‘Y’ leads, ceramic/ferrite chokes etc.

9. 

Receiver battery. 2 x 2400 - 2800 mAH 5-cell packs recommended.

10.

Ignition switch and battery for motor. 4 cell 1400 - 1800 mAH recommended.

11.

Powerbox 40/24 and dual powerswitches for Rx batteries.

12.  Fuel tank (1500 ml) with gasoline stopper. We used a Dubro S-50 in this model .

13.  Cable ties in various lengths.

14.  Propeller. Carbon 32 x 10 or 32 x 12 Meijzlik or Menz.

About the 3.1m SuperXtra

Building on the experience gained with our legendary 3m 330S Extra, we have designed the
‘Super’ to be the best flying plane in the skies. It has a fully-floating carbon blade spar, 20% larg-
er ailerons, bigger wing-span (3.1m/124”), stretched fuselage to allow 2 wing positions,  reduced
rudder counter-balance to make the high-speed flight rock-stable, and the canopy is now the
larger ‘L’ version for improved knife-edge performance.

The level of prefabrication is carried to the limit. Canopy frame mounts, control horns, servo
mounts, fuel tank tray, muffler mounts, gear mounts, mounting plates for the receiver and power-
box, battery trays ...  etc., etc, are all pre-assembled, aligned and checked at the factory before
shipping to you, ready for your hardware installation.

Did you read the warnings above, and understand the instructions completely?

Then, and only then, let’s start assembling your Composite-ARF Extra 330L.

If not, please read again before you start the assembly
