I have a MonstIR that I am putting on an HDX5106. I am going
to use the M2 rotator that I got with the tower. If it breaks,
I am going to replace it with a prop pitch. The ProSisTel will
not fit into my tower. Probably not even a 689. Neither will
the large Alfa Spid, and the smaller one is not strong enough.
AFAIK, there are no other alternatives, unless you want to mount
a ProSisTel or large Alfa on top of the tower. Then the rotor
has to take all that extra stress, or you have to build a superstructure
on top of the tower with a bearing above the rotor.
