Hook the Pacific Aero starter up to 14.4 volts (dual 7.2V car packs as shown), and it will have even more grunt. I will try to see if it can turn over a DA 50.

Here is a short video of me starting my Brison 2.4 (39cc) gasser with the Pacific Aero starter: [link=http://www.warbirdobsession.com/starters/starting_brison24.wmv]PAM Super Starter Video[/link]

When necessary, I use a Dynatron equiped with a Miller belt geared attachment. On 24 volts I think it will turn over anything up to my Buick Ultra!
