About the EMB-312 T-27 Tucano

Projected in 1978 under Joseph Kovacs direction by Embraer, the EMB-312 is a single turbo prop engine basic

trainer powered by Pratt & Whitney Canada PT6A-25C turning a HARTZEL three blade prop , low wing with two

MB ejection seats. The EMB-312 was christened “Tucano” an exotic brazilian bird by a cadet.

Designated as T-27 (or AT-27 for light attack version) by FAB (Brazilian Air Force) 168 units were delivered. The

6 first aircraft equipped EDA (Air Demonstration Squadron AKA Smoke Squadron) in September 1983.

The T-27 Tucano was a great success at the international market , offering a cockpit with instruments displayed

in a very similar way to modern fighters with low operational cost. More than 800 units were sold to many

countries as Argentina , France , Iraq , Paraguay , Peru , Venezuela , Egypt and others. It was made under license

by Egypt and England in a different version named “Shorts Tucano”.

At FAB the Tucano is used by AFA (First Air Instruction Squadron at Air Force Academy) , and was used by many

other squadrons including Fighter Groups , Observation , Defense but the main highlights always shined at EDA

Squadron , the Air Demonstration Squadron , eagle’s nest of proud and high skilled pilots.

1 1 aluminum wing tube at stabilizer (12,70mm x 1mm x 340mm)

C.G. point is at 130mm (5.11 Inches) from the leading edge , measured at the wing root. Wing chord is

453mm (17.83 inches). To check the balance hold your airplane in the inverted position by the wing root at

the indicated C.G. point , without fuel. Retracts must be retracted. The airplane must present a light nose

weight tendency. Never hold your model airplane by the wing tips only! Always hold it by wing roots

(closer to the fuselage). Never take off your model airplane without checking the balance! If there is a

tail weight tendency you must add weight to the front of the model airplane until the balance is correct. A

model airplane with tail weight tendency will not fly as it should ! It can cause serious accidents and damage

to people and properties around the flying area which Juniaer is hold harmless.

Linkage , Horns and Hard Points:

The model airplane has high wood structural reinforcements for control horns installation at the ailerons,

flaps, elevators and rudder. These points are 40mm x 40mm (15.75 inches x 15.75 inches), positioned at

strategic places and must be followed right as the instructions below, under risk of loosing control causing

damage and risks to people and properties around the flying area. If you wish to modify or adapt equipments

that requires modifications on the original project never do that by your own, please get in touch to Juniaer

customer service to verify the possibility of installation.

Ailerons: 2 simple horns are needed, 25mm to 35mm (1 1/8” to 1 ¼”) tall. Servo arms (20mm to 25mm) (1”

from center to the end) must be positioned to the wing root side. Note that both sides of the wing has the

same positioning. The horn hard point is centered with servo arm slot. Distance between center of control

arm and control horn (in neutral position): 92mm (3.62 inches). Servos must be installed in hard wood

blocks glued with epoxy at the servo tray cover.
