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

Installation Plate

The main services installation plate is pre drilled 

and slotted to suit equipment recommended by 

CARF-models. If you have ordered the CARF 

pneumatic pack and will use a JetCat turbine 

your work is much reduced.

 (Photo 30)

The turbine accessories are mounted on one 

side of this board and the air system valves 

on the opposite side. Plan your installation by 

working on the various connections that need 

to be made in, around and under the installation 

plate. Working from the front of the aeroplane 

is easier and the space increases as you 

move rearwards!

The Tutor comes out quite tail heavy, so install 

as much equipment as possible in the nose area. 

The use of large heavy batteries is a benefit, 

less charging and less dead weight. Either way 

the overall weight of the Tutor makes for a very 

lightly loaded aeroplane.

The optional air system includes a single air 

tank, which holds sufficient capacity to operate 

the gear, doors and brake system. The builder 

has the choice of using a second tank for the 

brake system, as there is ample space for an 

additional tank. In this case the air supply for 

gear and doors should be split to supply the two 

double action Jet Tronic valves. The installation 

shown, features T pieces located close to the 

valves, splitting the air to supply the nose and 

wing units and further T pieces on the lines 

to the wing to split the supply for each wing. 

Five airlines are required to each wing, air up 

and down for gear and gear doors and main 

wheel brakes. There are 10 pairs of ¼ turn 

connectors supplied for the wing/fuselage joint. 

Use difference colour airline fitted with colour 

tape or markers and mix the male/female sides 

to ensure the wings are connected correctly 

each time.

The fuel system is critical to the operation 

of any jet turbine model. All the equipment 

supplied by CARF-models is fit for use and used 

by all the team pilots. The installation shown 

has the header tank mounted close to the main 

fuel tank and fuel pump forward of this position. 

Use large bore tubing with this set up. The tank 

overflow fitting is formed from the brass tube 

supplied or any large bore fitting of your own 

choice (minimum 3mm inside diameter)

If you are new to turbines and require further 

information and help your CARF-models rep 

will be happy to advise you.
