I have the ripmax trainer 40 with os 46 la.It is a very good trainer plane and very sturdy!
My thought is that the 46 la is ok for flying her but if you want to do some aerobatics like large loops cuban 8 ect you have to go with
the ax because i think that she is a litle in heavy side.In inverted flight she wants all the down elevator just to stay level,but landings or flying in windy days is a piece of cake!
