I'll have several refurbed rotors w/controls at Dayton, including a TailTwister, a HAM 3, two HAM 2, a TR-44 and an AR-22. These were inspected, repaired if necessary, lubed, painted and tested by a local guy that does a LOT of these and has an excellent reputation. Flea # 2923 Contact me if you are interested. Alan, N3BJ
