ThePilotsPilot Thank you for adding me! Added you back! I hope you will find the aerospace content that I share interesting and relevant! I am not really familiar with your project although I certainly recognize the name Bob Hoover. If you have any sneak peaks of your project you are invited to join and share them over at https://plus.google.com/u/0/b/105638235158088183308/communities/104184795908703611647  for anything to do with Radial Engines and  https://plus.google.com/u/0/b/105638235158088183308/communities/104704596752604414893  for anything to do with V Engines. Hope to see you there!
