Yes, I have several new, extra large prop pitches.  Had I thought it would not hold this particular antenna I might have tried to use the brake, but instead I removed the brake before installing on the tower.  I should play with one of the new ones.  It would not be difficult to replace the motor.

I've sold a few of these prop pitches.  If anyone is interested, let me know.  They are big - 102 pounds if I remember correctly which is about triple the weight of the small one.

73... Stan, K5GO
