About 1/2 the price of the rotor blades.I think it would be a great tool as well! What do you think the cost would be to put something like this together? If it's affordable I could see it being a good tool for each chapter to invest in. Each member could pitch in a little cash to help better train new members. Also you could even use it as a way to introduce people who have never flown in a gyro to see if it's something they want to pursue.
