Manuals - Contra Prop

JETI Contra-propeller drive is very useful for acrobatic models for many reasons, for example, reducing the effect of motor torque on the fuselage and eliminating the gyroscopic effect of the propeller. The JETI Contra Prop drive are designed with a planetary gearbox, where the speed and power of both propellers are split.

 

 

JETI Contra-propeller drive has a higher efficiency (6 to 16%) compared to a standard single-propeller drive. Lubrication of the gearbox is very easy and it is not necessary to disassemble the entire drive, all you have to do is remove the front spinner and the supplied lubricant is applied through the hollow shaft directly to the gearbox. Lubrication of the gearbox is recommended every three hours of motor operation. The drive is tested and used for more than three seasons by aerobatics legend Gernot Bruckman.

Benefits of JETI Contra Prop:
- elimination the gyroscopic effect of the propeller
- reduce the maximum torque that goes through the fuselage of the airplane from the motor
- elimination of P-factor (a single propeller at a high angle to the direction of the flowing air
has a different thrust of each blade and therefore the aircraft has to be stabilised by rudder
input)
- the planetary gearbox of the drive performs the differential split of the power on the each
propeller. This solution guarantees a more stable flow of air around the fuselage compared
to belt systems that have the same rotation speed for both propellers.
- the optimized planetary gearbox for long service life is based on the technology of
manufacturing industrial gearboxes
- the gearbox lubrication system does not require the drive to be removed from the airplane
- powerful PHASOR motor with high efficiency allows the use of low capacity batteries
- more than double the braking effect of counter-rotating propellers during a steep descent
- higher drive efficiency 6 to 16%
