[TowerTalk] US TOWER MARB

[Dave]

    I am wanting to install the US Tower MA-40 and I am contemplating using
the MARB fixture.   Is anyone using this configuration?  My questions are;
     How do you decouple the mast from the rotor to lower.
     Does the whole mast turn, or is there an insert mast up the middle.
     What is the size of the mast that turns.
     Lastly, any rotor recommendations.
 
Thanks
