Well I decided it's time to move up from 1/2A...not that there's anything wrong with it...flew it for YEARS!. I was looking at the Brodak Jr. Lightning Streak that recommends an .09 to .19. Am I okay starting off with an .09 or shoudl I start larger? I bring up the 1/2A Pathfinder (I have one on the closet shelf) and it is actually larger than the Jr. Lightning Streak by a few inches. It claims engines from .049 to .07 (I had planned on using a Norvel .061). Could I stuff an .09 in that instead?

Thanks,

Rob
