When I had the 1930 set at 5 turn, I wasn't very happy with the performance on my emax... Why don't you run it at 9 turns... and 18 cells.. that's a much better setup, IMHO...
it's only an extra 6 cells... :) but a lot more power I think..
one of the 1930 @ 9 turns, and 18 cells.. is more punch than my buddys Savage with an RB TM28...
