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.
