[TowerTalk] Rotor Selection-Need Help

[David Gilbert]

That's kind of odd.  I've been using a PST-61D to turn an OB16-3 and an 
OB2-40 for about four years now with only one issue, and that was due to 
a humongous lighting strike that fried my controller even though I had 
suppressors on all the lines.  The motor still worked fine.

I don't remember if the motor in the PST-61D is fused or not, but I'd 
certainly trouble shoot the thing to make sure it wasn't something 
simple before spending close to two grand to replace it.
