    I am using a HITEC HS65HB (use for heli) servo. is it good to go or not guys ???

      Finally after much trial and error and time spent modifying it, at last completed my first paraglider. Not perfect but happy with the end result.
      Now to see how it will perform in flight. Wish me luck guys...

        Hum … which is the front end??? The single wheel or the two wheels???

        Looking at the propeller direction, the two wheels is the front end. Is this your intention?

          Direction

          Bro,
          The single wheel is the front end. Have you seen one of these thing fly? It's really very relaxing to see. Once at JW there were like 4 of the Para Glider flying all at once. Cool.
          So you will be flying sunday usual?

            You got it spot on Ben. I often heard JW mentioned always but where is the exact location you guys fly and timing as well. Care to enlighten me. Can i join in ? Would like to maiden it this weekend if possible. Maybe need some help from you fellows should anything happens as i fly helis now and have forgotten all my plane basics already.

              Single wheel - front
              Double wheels - back

              I know you will want to tell me my prop is in the wrong direction but when i tested the motor, i feel the air coming out from behind, so my air flow direction is correct, right ???

                You may feel the airflow in the correction direction, but your prop is NOT functioning at it's best efficency !!!

                Lol ! ...you REALLY lost touch with your airplane basis !

                  Got your msg, i will reverse the prop and try again... Thanks

                    Bro use big std servo w/long servo horn
                    & u have better turning....

                        since u r using it for pusher, the prop size printing should be facing towards the front. from the pic, i assume the printing is towards the back. u should turn the prop over so that the printing is facing the front. after u turn over, the rotation will be reverse. so u just swap any 2 motor wires and voila, u have it... this way, i think it should be at its peak performance...

                          Excuse me. How should the rotation be reversed after flipping the prop over?

                          If the airflow is coming from the correct direction, it means that the rotational direction is correct. If you got the prop mounted backwards, it'll only lose lots of efficiencies, and won't change the direction of the airflow.

                          Propellor blades are simply tiny wings with airfoil. Just make sure the convex side is facing forward with respect to the airflow.

                            hehehe i also dont know how i explain it. ok lets use the pic. btw this is just my experience. not an expert on it though and apologize if its misleading. hehehe

                            right now his prop is facing to the back. rotation is cc. therefore the para is moving backwards instead of forward. if u swap the motor wires, the para will now move forward but the blade will be turning from its trailing edge instead of its leading edge assuming the prop is a mini wing. dont know if its right. hehehe

                            if we invert the prop to face the front, the prop will still be turning from its trailing edge, therefore we should switch the wires right? i think it happens to me once before. or is it whether the difference is between a pusher prop and a normal prop? oops...

                              Yes, but when he mentioned that the airflow is blowing correctly, doesn't that mean that the motor is already wired to rotate clockwise, viewing from the aft? With correct airflow and rotational direction, all he need to do is just to flip the prop over.

                              I know what you mean from the beginning. You are assuming that the motor is running counter-clockwise with the prop in 'tractor' configuration, viewing from the aft.

                              Leonmike,

                              With reference from what you mentioned, your motor should be spinning at the correct direction. However, your prop is mounted in the wrong ORIENTATION. Just flip it over and you'll notice a big difference in thrust and noise.

                              Having said that, spinning a standard 'tractor' prop in the opposite direction, like what you are doing, will tend to loosen the prop nut. I suggest you apply a drop of CA or threadlock on the threads while tightening the nut.
