[TowerTalk] Tailtwister / Ham4

[Todd Coulter]

I don't know if this has been answered yet, but this is off of Norm's
Rotor Service website (www.rotorservice.com) under the FAQ page. I hope
this helps.

14. Can I use a Ham-2 rotor control box with my T2X rotor? Are the
Ham-2, Ham-3, Ham-4 and T2X control boxes interchangeable? 
Yes, for the most part, all of the 8-wire rotors except for the TR-2
series are interchangeable. You can use a TR-44 series 3; Ham-M series
3, 4, or 5; CD-44/Ham-2; CD-44/Ham-3; Ham-4; or T2X control unit with
any of the listed rotors or vice versa.  However, the Ham-M and TR-44
series 1 and 2 rotors were wired differently and are not interchangeable
with anything else.  So, trying to use a series 1 or 2 control on a
newer rotor will destroy the rotor pot instantly. 

To be sure that you have one of the interchangeable controls, verify
that the motor start capacitor is across terminals 4 and 8.  To verify
that the rotor is one of the interchangeable models, look for the
500-ohm pot resistance across terminals 3 and 7.  If your rotor and
control unit pass these inspections, they are interchangeable with
others which also pass.

 I don't have the diagrams - can a Tailtwister controller be used on a 
Ham4 rotor?
