Yes I thought about the old OPS, Picco, Rossi idea tho' the YS seemed a little heavy-sure would be nice if some mfg.'s made 50-60 quickee or pylon motors I'd love to have a 60 size SE quickee-type engine or three but all they make are 40's. Also would rather have something that parts were readily available if needed - which is why the MVVS-Tower engines were mentioned...Thinking about looking at some of Webras new motors since they have a rep for being light and high revving, but would still like other ideas if anyone has any?
