[TowerTalk] G-800SA capability

[Frank Mayer]

Read your specifications.  You severely overloaded your rotor.  Calculating your K factor is crucial.  It takes into account not only wind area but boom length.  It's all in the owners manual.

  My G800 trashed the gears in 3 years turning 2 33 foot long 2 meter yagis,
  maybe 6 square feet of windload total.

  I think that is probably a bit much.  My G-800SA is on a swinging gate
  side-mount, turning a Force 12 C-3E, and I find it occasionally will stall
  as the beam goes through the point at which the side-mount arm is
  perpendicular to the prevailing wind.  This only happens with wind > 30
  miles an hour, but I think it is an indication that the torque of the motor
  is limited.  I would anticipate problems turning that much wind area under
  some circumstances, and the possibility of damage to the brake, although
  mine has not shown any tendency to drift so far.
