the 42 foot pole is a tilt up with guey wires,my first. the 47 foot pole is buried five foot in concrete, 53 foot total w/ track and wench setup to raise genns, real fast and easy, even for an old man like me. at the present time i am flying two amtrack thirty volt motor jens but have had a ten foot danb copy up and a couple of different gear up units with different pm motors. i am trying to develope some fiberglass blades and keep changing them out to improve or discard. i have seen the poles sway in 60x wind gust but they come through fine. pepa
