I know weight is weight, but from experience dont waste your time with the wand. If you can fit the FOD screen and starter set up on your engine in your installation for 5oz, do what we do with the manual start turbines- just have an external battery pack with a deans plug or a neat electrical plug of your choice with the other end obviously soldered into the wire going to the starter motor. works a treat. Install a micro switch so you can vary the speed/ initiate spooling the turbine on start or whilst cooling proportionally to pressure when depressed. Wand works fine, but its a lot easier to pop your hatch, connect the external battery up and start/ cool turbine than fiddle around trying to make square contact with the wand on the compressor nut. My 2 cents worth.
Cheers.
