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

Final Set Up

The Tutor comes out very tail heavy, it has a 

long tail moment and the pipe is in the ‘bullet 

proof’ category – it won’t buckle or burn 

through! The high tail also requires extra 

fuselage structure, so expect to add a sizeable 

amount of weight in the nose area. Depending 

on battery weight and exact set up you will need 

to place between 700g and 800g of weight in 

the nose area. This is mandatory, the aeroplane 

is still lightly loaded, even with this weight and 

will not fly at all tail heavy.

Control Movements

Ailerons 25mm each way Expo 25-35%

Elevators 25mm each way Expo 35-45%

Rudder 40mm each way Expo 40%

Flaps Measured at fuselage fairing. Take Off 

20mm. Landing 65-70mm

Balance point is measured at the wing tip in the 

last panel line. 60-65mm back from the leading 

edge is a safe position with the tank empty and 

gear down. If you prefer a softer elevator feel 

you can go 10mm in front of this position.

With the balance point as stated, no elevator 

compensation is required with flap in 

either position.

The CARF Undercarriage set requires between 

85 and 95psi to operate reliably. The Brake 

system works as required at 80psi.

The Tutor is a pleasure to fly, a large group of 

CARF team pilots have flown the prototype 

aircraft and all were surprised just how good it 

flies, rolls are particularly easy and track well. 

Large loops do require lots of power, if you 

come into the manoeuvre at scale speeds. The 

Tutor maintains momentum well, but requires 

quite a long period of power to get past the 

fat fuselage and thick wings drag. You will 

very quickly learn the various power settings 

required. Slow flight is a particular pleasure 

with the large flaps producing plenty of drag. 

Landings are very straight forward, the Tutor 

is very stable on the approach with flaps and 

gear down, and only a small flare is required 

to grease the main wheels onto your chosen 

touchdown position. The super wide main track 

is very stable on the ground even in a cross 

wind. We thank you for buying the Tutor and 

like our Hawk, expect it to be a pilot favourite.
