RE: Evolution 61 or OS61 Which one inverted ?????
Harry,
Thanks for the reply
I am stuck with a 12 oz tank. The plane is a World Models Intruder. So a .61 would be my limit. I have heard 4 strokes will load up inverted quicker than a two stroke.
You made a very good point about the carburater. Not shure how good a Evolution carb is. But OS is known for a great carb.
