It is the result of our never-ending pursuit of excellence, by balancing stability, maneuverability and performance for .50 size machines. The head precisely follows your most minute stick movements. The new rotor head is our answer for every helicopter flyer, from novice to top-level 3D and F3C pilots.
1.FZ-5 Rotor head
Higher stability should give more confidence to beginner pilots for their first practice.
The head reacts to any slight stick movement, moving precisely as stick inputs. For maneuvers, the machine tracks straight as in airplane flight. For loops and rolls, the heads reacts linearly, resulting in beautiful maneuvers in the air.
For 3D maximum pitch stroke is 30°, same as SSZ-4 head from Turbulence. With new design swashplate, approx 60% more cyclic range possible compared with previous design. The new SDX is perfect model to start practicing 3D, up to the top competition level. The head design will not cause binding with any maneuvers, while you can enjoy 3D world champion performance.
Other parts are designed or improved with harder flight in mind, such as 10mm main mast, 8mm spindle, 8mm thrust BRG, 8mm radial BRG. SDX has nearly same strength and durability of 90 size models. There are several different setting possible with different holes on seesaw and mixing arms. Stabilizer blade weight is adjustable from approx 19g to 32g by taking off weights inside blade.
New design cabin with better aerodynamics. Cabin is supported by 4 plastic body mounts, making taking cabin off easier. Cabin is plastic with durable resin.
3. 90/120/135 swashplate
The new design swashplate has larger inner bearing (Up from 20mm to 25mm). This eliminates interaction with aileron and elevator control. The parts is same size as Eagle 3/Turbulence swashplate. 90 HPM, 120 SWM, and 135 SWM can be shared with same parts.
The main frame is made of high strength engineering plastic. Excellent performance, design, and durability are achieved by the one-piece main frame with the bearing holder and cooling fan cover.
120 and 135 SWM can be chosen. All linkage levers comes with bearings and push pull linkage.
Standard fuel tank is 480cc. It is easier to check how much fuel is left inside fuel tank. The tank is large enough for 50 size flight. The tank is held to main frame with floating rubber to prevent bubbles forming from vibration. Reserve tank ( 0414-483 ) can be used. Reserve tank is option and not included in kits.
7.Low height skid
New design 1pcs low height skid. It is easy to assemble and improve aerodynamics.
Mass production parts will be white landing gear.
8.SWM rudder servo
For SWM, rudder servo can be mounted in front on servo mount. It prevents rudder servo from engine exhausts. To prevent, early wear for rudder linkage rods, rudder rod is covered by plastic guide pipe.
SDX uses tail housing from 90 size Turbulence. The 5mm housing uses 2pcs thrust bearings and 4 radial bearings. Tail pitch plate is supported by 2 pins for better tail control. Tail is belt driven.
New shape plastic tail blades. Mass production parts will be blue.
