After some research, I'm going with a couple of 1/8 inch carbon fiber rods from Tower Hobbies and I've got an extra training gear set from a Blade CP. I'll cut the rods into 4 pieces, open up the holes in the orange ping-pong balls and build up a set. I was hoping something was commercally available but obviously not. Hmmmm, maybe this is something I can produce and sell. Hmmmmm
