Page 50: Lateral Balance
The Dynali H3 EasyFlyer ‘Sport’ is equipped with dual controls. Apart from solo flights, for which the pilot must be in the left hand seat, the Dynali H3 ‘Sport’ may be flown from the left or the right hand seat. In order to guarantee the easy piloting of the aircraft, the left hand side must always be heavier than the right hand side. -
Page 51: Section 7 - Systems
SYSTEMS SECTION 7 - SYSTEMS The purpose of this chapter is to introduce the pilot who has not assembled his Dynali H3 EasyFlyer ‘Sport’ to the various systems forming part of this helicopter. Further information can be found in the assembly manual. We advise all pilots to read through this in order to better understand the design and mechanics of the Dynali H3 EasyFlyer ‘Sport’. -
Page 52: Engine & Engine Mount
The stainless steel sleeves have a small slot in the middle. It enables the sleeves to open under shock, preventing the breaking of the aluminum legs. The tail boom of the Dynali H3 EasyFlyer ‘Sport’ is made of aluminum. It is supported by two carbon struts. -
Page 53: Main Transmission
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS ➢ The Rotax 914UL 115HP with TURBO, which provides for the maintenance of the full power range at any altitude. Although there is some added weight resulting from the addition of a turbo and associated equipment, this version promises to be popular for heavy pilots in hot and high environments. - Page 54 Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS Four V-belts transfer the movement to the receiving (driven) pulley which houses one freewheel. The freewheel is oil lubricated and can bear a torque of 660Nm. It drives the rotor while the engine is running and keeps it free of movement when the engine is stopped or idle (failure or landing).

Page 55: Main Transmission Gearbox (Mtg)
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS MAIN TRANSMISSION GEARBOX (MTG) The main transmission gearbox transfers the rotating movement from the main transmission shaft to the main rotor mast. The MTG of the H3 is dimensioned to support 250 HP whereas in reality it only has to bear a maximum of 115 HP. The total weight of the assembled MTG is 15kg. -
Page 56: Tail Rotor
All controls operate through control rods with ball joint endings. The flight controls of the Dynali H3 EasyFlyer ‘Sport’ operate in the same manner as those of most other helicopters. The cyclic and the collective control the pitch of each blade via the swash plate. - Page 57 Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS WARNING ! The controls are very sensitive, this being why we recommend frictions on the three controls. Fully unscrew and re-screw 6 threads the lateral frictions and 11 threads the pitch friction.
-
Page 58: Radiators
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS The friction of the collective lever is set by the degree of tightening of its attachment bolt. The rudder pedals act on the pitch variator lever of the rear rotor through two teleflex cables. -

Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS SECTION 9 - SAFETY TIPS General This section provides miscellaneous suggestions and guidance to help the pilot operate the helicopter more safely. It is essential to warn the owner/operator about several risks that are too often underestimated or neglected through force of habit and to provide with the experience acquired by the whole family of pilots of light helicopters. - Page 65 Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS Entering the vortex In the event of descending too fast or moving forward with a tail wind, there is a danger of entering your own vortex and catching up with your own turbulence. The rotor operates in turbulent air and loses a large part of its lift.
- Page 66 Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS Lateral translation Excessive and longer lateral translation has to be avoided at all means. An engine failure during a lateral translation close to the ground may have fatal consequences. Flying low on fuel is dangerous Never intentionally allow the fuel level to become critically low.

- Page 70 Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS Parking Restrain/strap the rotor blades which flap in the wind. The shocks leave traces of impacts on the balls of the bearings. Transporting the helicopter on a trailer Without main rotor blades or support the rearward blade. Possibly, on a short trip, let the blades hang and prevent flapping by using straps left fairly loose.
- Page 71 Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS This sound always accompanies blade same position. The "roar" in the tail pipe comes from the pinions of the RTG. When the tail rotor turns slowly, rear blades, one after the other, falls in its roots, causing a “knock”.
