The Canadair CL-41, given the designation
CT-114 Tutor in the Royal Canadian Air Force
was used as a jet trainer. Designed and built by
Canadair around 1960, the aircraft went on to
serve as the Canadian Forces primary jet trainer
until 2000. The Tutor is perhaps best recognized
as the aircraft used by the Snowbirds team, the
scheme represented here. Other schemes are
available, look at www.carf-models.com
Following on from our hugely successful BAE
Hawk, the Tutor is the perfect scale looking
sports/trainer jet. The Tutor would make a
perfect first turbine aircraft for people used to
handling large aeroplanes.

Some of the recommendations we make are
mandatory and others can be sourced and
chosen by the builder. The items we list here
are highly recommended by CARF and have
been tested on both the prototype aircraft used
during the development of this aeroplane.
Cutting corners to save a few cents can only
reduce your enjoyment of this wonderful
product. CARF models form partnerships with
companies known for quality, guaranteeing
reliable landing gear operation. A must!
1. Servos (minimum 8 high quality servos) All
the main control surfaces require a minimum
11kg digital servo such as the Graupner/JR
8411/8711 metal geared servos. Both the
prototype models used JR 8411 and 8711
servos and we recommend these for perfect
results. The tailplane servos need to be
19mm wide servos like the 8411.
2. Heavy duty servo arms are recommended,
for the JR servos we used JR part JRPA215
or Graupner #Nr 3544. Two packets required.
Aluminium arms are not required.
3. A receiver power supply system like the
excellent Powerbox units are recommended,
these all use two separate batteries and
feature independent circuitry for true
redundancy. The Tutor tends to build quite
tail heavy, so any size of PB can be used and
larger batteries are recommended.
4. Turbine choice. Turbines in the 14-16kg
(30-38lb) thrust range can be used, both
prototype aeroplanes used JetCat 160SX
turbines. Turbines in the 16kg (36lb) 160N
thrust class are perfect for this aeroplane. All
CARF models display aeroplanes use JetCat
turbines.
5. Retractable Landing Gear sets are available
from CARF. The Tutor was designed
specifically around the German manufactured
Behotec C50 units, the high quality set
include three units and legs, the mains
fitted with Intairco wheels and high quality
brake units. The 112mm 4 ½" main wheels
and 90mm/ 3 ½" nose wheel make grass
operation a breeze, even with the straight
legs supplied.
6. Landing Gear support equipment is
also available from CARF models. The
Tutor requires four air rams to operate
the gear doors. Robart 165 cylinders are
recommended. The retract valve chosen
needs to operate air up/down units and a
suitable method of controlling the gear door
opening sequence.
7. Our Tutor has all the gear doors stay
open when the landing gear is in the down
position simplifying the operation. The
C-ARF air support set features high quality
