I bought a new os 46 LA for my decathalon. Everyone is telling me I would be much happier with the OS 55 AX on this plane. I'm currrently running a Fox45bb in a Tucano 40 that wieighs 6.75 lbs without fuel. It flys nice. The Decathalon weighs in a 6.15 lbs (with out Fuel). I need to also convert to 2.4. So my question is, should I spend the money on 2.4 and fly with the OS 46LA or forget about the 2.4 and go with the 55AX? My instinct tells me to go with the 2.4
