Accessories
Below are the things you may need to get your Composite-ARF Extra 300SX in the air. Some of
them are mandatory, some of them can be chosen by you. What we list here are highly recom-
mended parts, and have been thoroughly tested.
1.
Power servos (min. 8 required). We highly recommend JR 8411 or 8511/8611 for all con
trol surfaces. For Futaba users, we recommend 2 x S9351’s for each Aileron, 1 x S9351
for each elevator, and either 2 x S3951’s or 2 x S9152’s for rudder.
2.
Aluminium servo output discs, or full metal arms (8 pieces). We strongly recommend that
you attach the phenolic servo extension arms provided in the kit to metal servo output
discs, or use full metal servo arms (eg: SWB ‘Double-Loc’ type)
3.
Throttle servo. Any standard servo will do (eg: JR/Graupner 4041/5391)
4.
Aluminum Spinner 120 - 125 mm/4.75 - 5” dia. eg: Tru-Turn. (Ø120mm carbon spinner
& CNC T6 alu. backplate available from C-ARF as an option, #810100 - 810103)
5.
Main wheels 115 - 125 mm (4.5 - 5"). Kavan Light or Dubro wheels are recommended.
6.
Engine 75 - 100cc. The DA-100 is probably the most commonly used engine for our 2.6m
span Extras. In these instructions we show the installation of this, and also a lightweight
option with a 3W 80cc single cylinder and tuned pipe set-up.
7.
Muffler/Canister or Tuned pipe(s) and headers. (Headers, canisters, tuned pipes and
Teflon joiners are available from C-ARF as options. See our webpage for availability)
8.
Tailwheel assembly. (Available as an option from C-ARF. Product # 801000.)
9.
High quality heavy-duty servo extension cables, with gold connectors. High quality
receiver and ignition switches, etc.
10. Receiver
batteries.
11.
Powerbox and dual powerswitches for dual batteries (available from C-ARF as an option)
12. Fuel tank (750 - 900 ml) with gasoline stopper. We use Dubro.
13. Cable ties in various lengths.
14. Propeller. Carbon Meijzlik or Menz 28 x10 for DA-100. 26 x 12 or 27 x 10 for 3-W 80cc.
