Wow, what a weird thread! Yes, I agree, Ed was very clear--in fact he was very clear about six or eight times, but it doesn't matter. People keep going back to the 46-ball-bearing-is-best advice no matter what the plane weighs, where it balances or what the pilot wants to use it for.

There are lots of terrific .36 engines out there that weigh around 11 - 12 ozs and have more power than almost any .40 of 20 years ago, like my Irvine .36 or the TT .36. They are excellent choices for lots of the lighter .40-size planes.
