  • New Sport Rotors

    I have a new set of Sport Rotors. These things fly excellent. Hardly any stick shake. Some vibration which I believe my prop is the next thing to balance.
    I have increased speed, faster rate of climb, and better turbulence handling.
    Kudo's to Jim for these.

    Here is a link to the video. These are on my Twinstar.

    Congrats Brent. I'm getting a set in a few weeks, including a SC head. Have heard only great things about these blades, and pretty much all things SC.

      My initial reaction to my sportcoptor rotors was that they were very smooth,and they were

      compared to my other blades. The other day I was in an RAF that was really smooth and I

      have been spending several days trying to get my blades smoother,its not gonna happen.

      I like the performance my blades have,speed, ability to almost hover on landing,etc but

      they have a vibration that's never going away,I have been tuning to 1/2 thousands of an

      inch and just can't get the blades really smooth,this includes a new RAF rotor head,and

      mast bushing. If anybody has any good ideas I would like to hear them.

      Don't get me wrong I really like the way these blades work,its just that pesky vibration

      that's driving me nuts.

        Perhaps a Sport Copter rotor head?
        I'd bet that your RAF head has some orbital effect. Their tolerances . . .

        Wasn't happy with my RAF's pitch instability, so I installed a Boyer H-Stab to my great satisfaction!

          I don't have a Sport copter or a RAF. Mine was custom made. Has larger bearings and a 5/8" teeter bolt I believe. It spins very true. I'm converting from electric pre rotator to hydraulic this winter.

            Kolibri the really smooth blades were stock RAF,blades and head,the head I put on my

            gyro was a brand new RAF head and did not make any real difference.

              When I purchased my Twinstar it had an RAF setup. I was never pleased with it.

                Best regards,
                I have flown 9-10 sets of RAF blades. I feel if yours were smooth then yours was the exception. Iv'e seen both balance and tracking issues with them.

                I've flown about the same number of Sport Copter blades. I feel the Sport Copter rotor heads and blades are far superior built and designed than RAF in my opinion.

                I've never hear of Sport Copter having hub bar issues like RAF has had in the past either.

                I do like the weight of RAF blades. They seem to hold RPM a little longer on the runway when landing. But harder to get stopped.

                  Brent your right I think that those smooth RAF blades are the exception, I really like the

                  sportcoptor blades,its that they are really sensitive to adjust,the shake that I still have is

                  different than the raf blades and ais not as objectionable in flight,my cruise speed is about

                  a good 10 MPH faster,I have found that the weight is more inboard than the old blades

                  which were heavier and slower to stop than the sportcoptor blades,however the sport-

                  -coptor blades do keep there lift a lot longer than other blades did,overall they are a big

                  improvement.And your also right in the fact that they are better in quality and strength.

                    This turned not to be any fault of the SC rotors, but with the poor quality RAF rotorhead, as eddie implicitly later admitted:

                      Eddie,
                      I notice that you have your blades up for sale on Barnstormers, What are your plans for replacement?

                        I've never had a set of sport Copter blades for sale.
