Adhesives
Not all types of glues are suited to working with composite parts. Here is a selection of what we
normally use, and what we can truly recommend. Please don’t use inferior quality glues - you will
end up with an inferior quality plane, that is not so strong or safe.
1.
CA-Glue ‘Thin’ and ‘Thick’ types. We recommend ZAP, as this is a very high quality.
2.
5 minute-epoxy (highest quality seems to be Z-Poxy)
3.
30 minute epoxy (stressed joints must be glued with 30 min and NOT 5 min epoxy).
4.
Epoxy laminating resin (12 - 24 hr cure) with hardener.
5.
Milled glass fibre, for adding to slow epoxy for strong joints.
6.
Microballoons, for adding to slow epoxy for lightweight filling.
When sanding areas on the inside of the fuselage to prepare the surface for gluing something
onto it, do NOT sand right through the layer of glasscloth on the inside foam sandwich! It is only
necessary to rough up the surface, with 60/80 grit, and wipe off any dust with alcohol (or similar)
before gluing to make a perfect joint. It is very important to prepare the inside of the fuselage
properly, by roughing up and cleaning the surface, before gluing
any
parts to it.
Accessories
This is a list of the main things you may need to get your Composite-ARF Pitts S12 in the air.
Some of them are mandatory, some of them can be chosen by you. What we list here are high-
ly recommended parts, and have been thoroughly tested.
1.
Power servos (16 ). We recommend JR 8511/8611 for the ailerons and elevators. Four
JR8411’s are quite sufficient for the Rudder set-up. (equivalents: Futaba 9351/9152)
2.
Throttle servo. Any standard servo will do (eg: JR/Graupner 4041)
3.
Aluminium Spinner 125 mm dia (5”), eg: Tru-Turn.
4.
Main wheels 125mm (5"). Dubro wheels are recommended.
5.
Tailwheel assembly. C-ARF can supply this as an option.
6.
Engine DA-150, or equivalent.
7.
Exhaust manifolds and tuned pipes. C-ARF can supply these for DA-150 as an option.
8.
Powerbus system for servos. C-ARF can supply the Powerbox range as an option.
9.
Tailwheel assembly of your choice. C-ARF can supply this as an option.
10. Receiver batteries and switches. Quality extension cables and connectors etc.
11.
Fuel tank (1000+ ml) with gasoline stopper for gas/methanol motor. We use Dubro.
12. Cable ties in various lengths.
13. Propeller, to suit motor choice.
