Yes, the AeroWorks planes, at least the 60 size ones, fly very well with 60 engines. I've had 4 of them (still got 3) and they're excellent with 60s on 'em.

MOF, the Yak 54 of mine, with it's OS61FX was clocked at 91mph the other week. Do I fly it around at that speed? Nah, but the extra speed helps loads on very windy days. It's vertical is excellent and at 3/4 throttle it's perfect for maneuvers. It's a 6.5lb airplane. My other AWs are 7lb airplanes. The previous two 60 size by other mfg's were 8lbs airplanes.

All of mine weighed in at or less than the advertised weights. That's something that is worth the money. I've got/had a number of other brand ARFs that are now sold or gathering dust that didn't come in at their advertised weight. And had a couple that had weak areas that cost me. The AWs seem to come with absolutely top of the line hardware (I've only assembled 4 so far) and I've yet to find a weakness of any kind.

It's often said of cheap ARFs that "you get what you pay for". When for most cheap ARFs, that ought to be, "you aren't getting what you don't pay for". So far, that's exactly true of the performance ARFs I've bought. In fact, the AWs provided even more value than I've paid for. I wish AW produced a 60 size Ultimate, and a........ lots of other planes.

Bottom line is that almost all ARFs are good values if you buy what suits you and your flying style and are an experienced ARF user. If you just bore holes in the sky the premium mfgs prices are a bit excessive for your needs. But getting what you pay for is true for a lot of mfg's both the top end and the bottom.
