Jim, I've flown mine with both the 46LA and the 46 FX I personally like the LA better as its lighter. I think you'll fine it plenty for this plane. Mine even has a nose gear retract installed. MIne is really quit fast. I'm turning an 11x7 APC @ 11700 with 15% Wildcat fuel with the 46 LA. The cowl is a waste of time it just overheats the engine.

Read the threads posted here on RCU it will save you a lot of headaches. There are 2 or 3 about this aircraft, just click on my name(jmupilot) in the lefthand column, then look for the LongEZ threads. If this your first Canard remember the elevator is BACKWARDS from conventional aircraft.
