I don't think I'd drop the ailerons, they are too far back on a Northstar and may cause more trouble than help.
But there is no doubt in my mind that the 40LA has to go.
Get a good Ball Bearing 46 - Even a cheap one like the TT or Evolution. They are great engines for around 80 bucks.
I've been flying them drooped for a dozen years Mike. No trouble at all. Can't tell you how much. I have a hard enough time remembering what I did yesterday let alone that long ago.
