Elbow or Wrist?

Actually, Precision Aerobatic (stunt) flyers use their wrist.

There is more to it than that. Some hold their arm straight out but many also bend their arm a bit.

I didn't mean to imply that they used the purely straight arm approach and relied only on the movement of their arm up and down. Centainly, on the square manuevers or those needing more deflection, the wrist movement is required for the additional control, but they usually follow their plane with their arm.

At the NATs, I was watching some of the fast combat flyers praciticing. In some situations, they flew with their arm at about a 80 degree bend and almost all of the control was wrist. I have always been amazed at how they can keep up with their plane. Most of the arm movement was just to maintain line tension.

Here is a video of one of my club members Mike Palko flying at Brodak's this year. Mike is a innovator of electric control line stunt ships. He scratch built this P-51 (Miss Bardhal) and it's one of the most beautiful stunt ships out there.The entire plane is Sig dope. You can see in this video how Mike keeps himself as steady as possible and just clean well rounded maneuvers. Mike has taken several 1st's this year. http://www.youtube.com/watch?v=dBY2rOEzOJM Ken
