parts including air valves from Jet Tronic to
control the gear operation, door opening and
brakes. Robart rams with required hardware,
suitable air tubing and a large capacity air
tank for landing gear/door operation. Filler
valves, Festo joiners and quick disconnect
joiners. We strongly recommend you use this
proven high quality set.
8. A radio system with a minimum of
7 channels could be used coupled with a
Powerbox unit and matchboxes, but CARF
recommend a quality system with 9 or
more channels to allow individual servo
connections to the receiver system. A
Powerbox unit is recommended particularly
as the Tutor has quite long servo leads. All
PB units feature signal amplification which
is critical for perfect servo resolution when
using long extension leads (talk to your
CARF rep for advice on a suitable system)
High quality extension leads are required and
a guide to the sizes and quantities required
are listed in the instructions.
9. The Tutor kit has been designed with a large
4.2,ltr fuel tank giving long flight times,
a space is also included for a smoke tank,
both available separately from
CARF-models.com.
The Tutor features a large cockpit area which
benefits from some additional detail. The Tutor
is a close to scale copy of the real aeroplane,
adding additional cockpit detail benefits the
finished aeroplane. C-ARF supplies a set of
mouldings to assemble into a basic cockpit tub.
The Tutor is approx 1:4.25 scale. The canopy
area is designed to be hinged and includes a
method of keeping it open. Access to the nose
area is through a scale hinged access hatch
which can be easily opened without tools. The
kit features a clear nose lens, which deserves a
light unit fitting. Various systems are available.
The high tail position and scale type flap
hinging mean the Tutor requires no elevator
mixing with takeoff or landing flap, this is

one of the easiest to land jet models available
today and would make a perfect first jet model.
The super wide undercarriage position makes
the Tutor very stable on the ground, even in a
cross wind.
We suggest you start the construction with the
wings and tail assembly, though any order is
possible as the wings and tail parts have been
factory fitted to ensure a perfect fit.
Radio set up you have several choices
dependant on how many channels you have and
your choice of Powerbox. The set up used here
is with 12 channels, each aileron, flap, elevator
has its own channel for the best redundancy.
Then you have a choice, if you intend to fit
smoke use a single channel for the rudder and
nose steering-if you use the same make servo in
each position the directions are correct without
a reverser. The nose wheel steering can operate
in the nose area and this has no ill affect. We run
gear and gear doors on separate channels and
simply use servo slow from the Tx to sequence
the gear and gear doors. Gear up the gear works
at normal speed and the doors are slowed, then
for gear down the doors work normal speed
and the gear is slowed. This works perfectly.
You could obviously use a gear door sequencer
and save a channel there. Brakes use their own
channel as does the throttle. The use of a PB
with matchbox facility or even the new PB
Cockpit version with built in sequencer will
allow less channels to be used.
