How high were you trying to go? How did you support the mast? For years, 
we've used the Al mast sections with a tripod fitting to rig a C3SS at 
30 ft or so for FD, 7QP, CQP. Photos in k9yc.com/7QP.pdf  Once in the 
air, we guy it. W6GJB found a vendor selling the tripod fittings at 
Dayton one year. As I recall, this was one of the tricks that K7JA 
showed in talk at Visalia or Pacificon that was a collection of good 
ideas. W6GJB is a pilot, and he found some real neat fittings that can 
be driven into almost any ground to tie down small aircraft. I think 
google for tiedown or tydown.
