RE: Engine Recommendation for LT-40
If money is a problem go with the LA, the .46, not the .40, more power and about the same cost. If you have another 20 bucks or so go with the other recomendations. I have flown my LT with the .32SX, the .46LA and the .46FX. Any will work but I like the LA46 the best for that plane.
