Before you watch this video
Be sure to read this post Paramotor Torque Effect Explained. Please be sure you clearly understand the difference between Acceleration Torque and Continuous Torque. Both have the same effect (a tendency to turn to one side), but happen in different situations and have different cause.
On the video you will see behavior of the SCOUT paramotor and the Dynamic Torque Compensation in action. The SCOUT flies differently from other paramotors.
Paramotor with static torque compensation (carabiner offset or diagonal strap) flies straight at level flight if correctly designed. There should be no tendency to turn. If, however, the pilots squeezes the throttle to full power, the torque effect becomes stronger than compensation and the paraglider starts immediately roll to one side due to Acceleration Torque. The paraglider continues to roll to the side further even when the propeller reaches maximum RPM, because Continuous Torque comes in action. The paraglider will turn to one side just as long the full power used. The paraglider will only return to straight flight when the throttle comes down to level flight.
The SCOUT behaves differently. There is no way to eliminate or compensate the Acceleration Torque. The SCOUT will therefore roll to one side just like any other paramotor. The Acceleration Torque is present immediately, but not enough airflow is generated yet as the prop is only accelerating. This lasts only for a very short time, maybe a fraction of a second until the RPM reaches maximum. As the prop turns faster it creates much higher airflow and the power of the dynamic torque compensation will increase until full compensation. At this point the torque effect is fully compensated and the glider swings back.
In this video I was not touching the brakes and I was not flying actively. This is why the paraglider continued to swing a little but continued to fly straight even at full power.
Watch this video now.
paraglider: Axis Pluto 2, 26sqm
paramotor: SCOUT carbon paramotor with Dynamic Torque Compensation (patent pending)
engine: Vittorazi Moster 185
propeller: 132 cm, ground adjustable set to a little less than engine’s max RPM
conditions: hell was freezing, little gusty but well flyable
pilot weight: 87kg
just a very short flight, had to land before sunset.
What is this good for?
Obviously, not having any unintended roll and turns is good for precise paraglider control. SCOUT has equal ability to turn to both sides, even under full power.
This feature is useful for pilots of any skill level. Either for taking sharp turns at low-level flight or for being able to control the paraglider easily just with weight-shift while holding a camera in hands.
Do your own test.
Fly at a steady constant flight and maintain level. Choose a target point just 90 degrees to the side where torque will turn you.
Sit straight, do not touch the brakes. Now add full power and count, how many seconds it takes until the glider turns 90 degrees.
My observation is that most paramotors take 8-12 seconds for a 1/4 turn. Surprisingly the glider size and type does not make any big difference. I have tested Pluto 2 26, Ozone Viper 2 26 and Dudek Hadron 22. Times were equal, the later two were swinging a little more.
Well with the SCOUT the time is infinite …
