 Frank or anyone. 
Frank, with your link up from the linear 
actuator to your side thrusters; 
are you setting them up to go through 90 
degrees. i.e. from horizontal, down 
to vertical. 
Is there a way of setting a link up so you can get 
180 degrees of movement  
without going to gearing? Or is this not worth the 
trouble as with 90 degrees 
of rotation & reversible motors you can go in 
most directions except up & 
backwards or down & forwards 
simultaneously. 
Regards Alan.
