[TowerTalk] FW: FW: Difference in TailTwister and Ham 4 torque values

[Matt]

Steve,

 

I disagree.  The differences in torque ratings which were published were
likely based on the strength of the ring gear, which was upgraded in the
past to the heat treated material.   To the best of my knowledge, the motor
and mechanical advantage of the gear train have always been the same,
thereby making the effective torque developed the same.

>>>  My question, and I have searched, what is the difference in
starting/running torque between the Ham 4 and TailTwister?

 

>  There is no difference in torque output between the Ham IV and the Tail
Twister.   

 

    Wrong. On page 154 in my UP THE TOWER book, the comparison table of
rotators has the Ham IV with 800 inch/pounds of rotating torque while the
T2X has 1000 inch/pounds - a slight improvement. These are manufacturer's
specs.

 

>  Both use the same drive motor and running gear ratios.  The Tail
Twister has a stronger rotor housing, improved mounting fastener
arrangement, and a stronger brake wedge setup.

 

    In some instances, they use the same parts.
