Curt & Steve;

I think I found a way to start the OS motor with the big spinner. I have a Hangar 9 12V PowerPro starter with the soft rubber cup. I was in my shop last night turning the motor with this setup and the motor was turning over. So today I went out in my back yard to see if this setup would start the motor. I would say after 5 sec on the starter, the motor came to life!!! You will have to push hard on the starter to keep a tight seal on the spinner. That big spinner looks so good on the AT-6!!! Now this setup may or maynot work for you, but it can be done!!! Now to get some good weather so I can fly her!!!
