The new generation CRS MKIII system, in addition to the obvious color changes, has almost all the components redesigned: new main shafts, new gear & pulley, new motors, even the screws & support rods are new.
- All new FAI F3A competition-level contra rotating system
- The thrust is about 20% higher than the uniaxial systems (compared with DA4), with lower power consumption
- CNC made pulley and inclined gears, quiet operation
- The main shaft and the motor shaft adopt hollow shaft design
- Maintenance-free design without adding lubricating oil
- Nearly zero propeller reverse torque makes the straightness of the model plane better
- The incredible uniform speed effect can be achieved in the descent/dive route
- CNC made lightweight gearbox bracket
- Carefully deployed gear / belt ratio eliminates the belt tight wheel mechanism
- Belt replacement cycle is 4,000 minutes (about 500 flights)
- Supports the common after-firewall installation of F3A, with optional Mount Kit. Also supports the before-firewall installation for stunt model aircraft.
