    Removing a rounded screwhead

    One of my flying buddy faced a rounded screwhead. I volunteered to help him resolve it. See peekture, it speaks louder than words. Just to share.

    Thanks for the reminder of this elegant method with the rotary tool. Last time I faced this with one on a heli frame I took out the self grip wrench, got a hold of the head and slowly twisted it out. Marked the frame... next time I'll remember the rotary tool

              I bought a set a long time ago.
              Well, not exactly the same type but works the same.

              It is basically a left hand screw.
              First you drill a hole, put the exractor bit in, and just screw out the broken bolt/screw.

              One very important thing to note is that the smallest bit may be too large to extract a servo screw.
              Maybe mine was a S$6/- cheapo.

              Then again, those stylo mylo ones may also not be small enough to handle small screws... expensive only.

              Any apek hardware shop should have the type I have in stock.
