Have nothing but good things to say about the pt40,on grass,our field,with the 40la the plane uses a bit of runway to build flying speed,with the fx engines they are a lot more brisk,the pt40 has more recovery built in than some trainers which as a trainer I really like.As lite as the plane is,high wind buffs it,check the center of gravity,if to nose heavy it will be sluggist in flight.

Have a goodun,John
