Another thing I forgot to add cosworth is that I found Firgelli will promptly help out with design questions using their actuators. I emailed Ian Greig at Firgelli (found his details here on RC T&C) with photos and digitally measured loads for the Firgelli actuators I proposed using and asked his opinion. He assessed my project and also put it to his engineering dept and came back with the answers next day. Another reason I'm using screw jacks - Firgelli were happy to offer advice on their products and they are in Canada - easy communication. Hope you get it sorted.
