Features:
FZ-4 rotor head
This head is designed for mild mannered smooth precision flying and the harshest of 3D oriented manuevers. Its smooth flying characteristics even in a 3D environemnent are ideal for the discerning F3C pilot. Through two fixed Bell/Hiller adjustments, the EVO head can be tuned as you feel necessary by changing the position of the mixing arms.

Linkage and pitch up system
All linkages are ball bearing supported for smooth direct transfer of control inputs. This is standard on both the 30 and 50 version EVO’s. The EVO 50 comes with push/pull linkages on both cyclic and collective controls for the ultimate in precision. There is no better control system designed to capture the power of the 50 size motors and turn it into aerobatic bliss.

Cabin
A new vibrant decal sheet is included to aid in high altitude flights. The cabin mounting system is improved with new rubber o rings and new molded mounting posts. Cabin mounting is simple and easy. Additional internal cabin supports keep vibrations down to a minimum.

19mm Bearing. holder
All Sceadu EVO have injection molded 19mm bearing holders as standard parts.

Direct Tail Drive System main gear
Injection molded Direct Tail Drive System main gear setup is standard on the EVO 50 and an option for the EVO 30. The DTDS gear system drives the tail rotor at all times allowing aerobatic capability in autorotation manuevers. The tail is also driven in low power descents for postive tail control. The gears are molded of extremely durable plastic for low cost and high reliability.

Main blades
New 600mm symmetrical main blades are standard for 50 models. All 30 models have wood 550mm main blades.

Muffler
A new muffler with removable baffle is also included.

Fuel tank
A new 480cc fuel tank has been added that is clearly visible in flight for quick fuel level checks. The tank comes with special tank mounting rubber feet that isolate it from motor vibrations. This new larger tank offers substantial flight time increases for the both 30 and 50 size motors.

Main frame
This simple yet well thought out main frame design fits both 30 and 50 size engines. Major components like the main and clutch drive train bearing holders are incorporated into the main frame for precise alignment and easy assembly. To also aid in proper center of gravity balance, a drive train layout similar to the winning SST Eagles is used which places the motor as far forward as it can go. The tank is mounted in the rear for visibility as well. A new higher quality fiber reinforced engineering based plastics’ formulation is used in the new EVO main frame.

Engines
Both 30 and 50 size engines can be used in the Sceadu EVO. By simply changing the motor mount, fan hub, and clutch bell, the Sceadu EVO can accept either engine. Of course, blades will need to be changed as well for the appropriate engine size. To aid in clutch system installation, a threaded fan hub is also used so centering of the clutch system is effortless.
