Composite ARF Tutor T-114 manual – [email protected]

4

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.
