Default Eagle II Balancing after engine swap

Hi all!

I've just bought an OS FX 46 to replace the OS LA 46 that is in my Eagle II. The primary reason(s) for doing this is that the LA seems sort of cheap and nasty, sounds like a 20 year old chainsaw with a broken muffler clamp, and it gets spanked by all the other trainers at thier field who are bye and large, running TT46 Pros.

TH FX is a bit more of a lump than the LA though. OS's web site says 9.6 oz vs 13.2 oz for the LA and FX respectivley, without mufflers. I can move the battery pack back (say that ten times fast) under the servo tray and pack some foam in there to hold it - currently it sits right behind the fuel tank with the RX.

Should that be enough to compensate for the heavier engine? Would a slightly more forward CG reduce the tendancy for the plane to float for about a mile and a half on every landing approach?

Along wiht the engine swap, I'm planning to change from a 10x6 prop to a 11x6. Good idea?

Thanks!
