Carf-Models Ultra Lightning Instruction Manual page 5

The self-mixing nozzles make it easy to apply exactly the required amount, in exactly the right
place, and it will not run or flow onto places where you don't want it! It takes about 1 - 2 hours to
start to harden so it also gives plenty of time for accurate assembly. Finally it gives a superb bond
on all fibreglass and wood surfaces. Of course there are many similar glues available, and you
can use your favourite type.
1. CA glue 'Thin' and 'Thick' types. We recommend ZAP, as this is very high quality.
2. ZAP-O or Plasti-ZAP, odourless (for gluing the clear canopy)
3. 30 minute epoxy (stressed joints must be glued with 30 min and NOT 5 min epoxy).
4. Aeropoxy/Loctite Hysol 9462 or equivalent (optional, but highly recommended)
5. Epoxy laminating resin (12 - 24 hr cure) with hardener.
6. Milled glass fibre, for adding to slow epoxy for stronger joints.
7. Micro-balloons, for adding to epoxy for lightweight filling.
8. Thread-locking compound (Loctite, or equivalent)
We take great care during production at the factory to ensure that all joints are properly glued,
but of course it is wise to check these yourself and re-glue any that might just have been missed.
When sanding areas on the inside of the composite sandwich parts to prepare the surface for
gluing something onto it, do NOT sand through the layer of lightweight 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 acetone or alcohol (or similar) before gluing to make a perfect joint. Of course, you
should always prepare both parts to be joined before gluing for the highest quality joints.
At CARF-Models we try our best to offer you a high quality kit, with outstanding value-for-
money, and as complete as possible. However, if you feel that some additional or different hard-
ware should be included, please feel free to let us know.

This is a list of the main additional items you will need to get your CARF-Models Ultra Lightning
into the air. Some of them are mandatory, and some can be chosen by you. What we list here
are highly recommended items, and have been thoroughly tested.
Power servos (min. 8). The Ultra Lightning was designed around the excellent JR 8511/8611
1.
range. See recommended servo list below. Another choice is the new Graupner/JR
DS8811 which has a little more torque and about 15% more holding power. The Futaba
S9351 should also be a viable alternative.
2. Metal servo arms (7 min). Most metal servo arms have a considerable amount of
'slop', due to manufacturing tolerances of the arms and the servo output shafts and
splines. The SWB 'Double-Loc' arms clamp on with no slop at all, and we have used
them on several C-ARF models with great success, which is why we are
pleased to recommend them here. A set for the Ultra Lightning is available as an option.
3. Turbine engine set. Recommended thrust range 13 - 19kg (25 - 40lbs)
4. Retractable Landing gear set. C-ARF have a high-quality precision Landing Gear set, with
wheels, struts, brakes, gear door cylinders, tubing etc, available as an option.
