I suppose not, there will not be mny that put a expensive motor like that in a $99 ARF, but my siituation being transient ( Away from home most of the time and more or less living out of a suitcase) it is what makes sense for my situation at the moment. Right now it is a toss up between the Pathfinder and the Cardinal. Had a Vector 40 been there done that and I'd rather build when doing a full fuse. But as I mentioned I'm not in the position to be building right now.
