[TowerTalk] Rotor Cabling Query

You also don't get power to the motor without engaging the brake switch, since the transformer that powers the motor circuits is in series with the brake switch.

And, if you disconnect the brake wire, the brake will never release!

No, Hy-Gain uses a spur gear drive which offers very little resistance  
to turning so they need a wedge to maintain position.

So will the HyGain Tailtwister hold securely with no creeping if I  
disconnect  the brake wire ?   I have had the typical stuck brake  
scenario with my old Tail Twisters in the past and I like the
idea of not using the brake circuit if possible. I always let it coast  
to a stop anyway.    I have a new TailTwister replacement going up in  
a couple of weeks.
