Torque effects

At low speeds you don`t have much speed above the stall.

The torque effect is putting the equivalent of some brake on the right hand side of the wing, so if you then add heavy braking on the left hand side the whole wing is being braked.

This can put you dangerously close to the stall.

Cheers, Alan

Hi

I don't understand why it may be dangerous to pull a tight left hand

turn under full climb at low speeds. ( against the torque).

Richard

Imagine the motor trying to turn to the right due to torque, your risers slightly twisted to the right then you pull a tight left turn, the wing turns left against the motor trying to turn right. Result = twisted risers, and the wing flying opposite to the thrust of motor. Action is to power off hands up and hope you have enough height to recover normal flight.

Hope this helps.

power off slowly, or you may spin right round in the opposite direction :D

Cheeeeeers

Got it.

Also chatted to Instructor today whilst stood around moaning about

wind speed and you all agree.

Simples.

I did a hang check today and found that there was very little force required to twist

and move paramotor 90 degrees off square. I was expecting a greater resistance

to staying square.

Please comment on this.

Thanks for replies.

Regards

Richard

the further the plane of the prop is from vertical the more tourqe effect will make its presence felt, when you do a hang check you want your motor to be leaning back just enough so that when you apply full power its sits upright, have you checked your harness is adjusted equally both sides?

Rich, We will hang you up in either a tree or a forklift and get your angle of dangle correct on your motor . :-)

The settings in the manual are normally close enough to eliminate any problems. :-)

SW :D

If you try to turn against the torque steering effect it could end up something like this. Some paramotors has more effect then others and it also depends on other factors how prone the gear are to this kind of reaction. But if the glider turns noticeably from torque steering then you should be careful.
