[TowerTalk] Rotor and controller choice

Thank you for the direct and list, 
informative replies. So many direct 
replies and I am grateful & I'll reply to 
each directly but I'll use the list to 
offer a global reply right now.

There was nothing but universal praise for 
the Green Heron controller so that makes 
it a done deal as regards controllers. I 
now have to decide on the rotor. 

At this point I will only be driving a 6 
meter 6M7JHV till next summer. It weighs 
18 pounds. The way I have used the 
tailtwister is bolted to a base and the 
antenna attached to the mast above. I've 
been informed this is bad practice and I 
need to use a thrust bearing to not abuse 
the rotor, even with light loads. I knew 
to use them for heavy loads but just 
learned something new. I'll make an 
arrangement in my roof tripod to make this 

So now, considering the desire to have a 
rapid rotation (using this 6M beam), a 
Prop Pitch is not in the hunt but based on 
the many replies, I have two options that 
I would do well to decide from that come 
at a cost effective package from Green 
Heron; the Yaesu G-2800 and the Alpha Spid 

Both of these rotors get about the same 
reviews on eHam. I like that the Alpha 
SPid is made in Canada, Yaesu doesn't have 
the best tech support but they're a large 
company with a lot of history. 

Any strong caveats with either one of 
these before I order?
