AeroWorks has two 60-90 size ARFs that are pretty good. They are smaller versions of their larger IMAC models. There is the Extra 260 and the Yak 54. Both have 60" wingspans and are the weight for 3D performance from a two cycle 60 glow. So they should almost duplicate the performance of IMAC competitive models AND look like them too. And looks matter to the judges. Show up with an Ugly Stick and it'll do the maneuvers, but won't suit the judges, and that's the drill.
I've just finished assembling the Yak54 and the design is almost identical to the 26% and larger birds only downsized to suit. It's also a premium kit. Excellent fit and hardware. And a number of things are already done for you. Example: the cowl is already setup to fit, holes drilled and blind nuts in the fuse to accept the attachment bolts. And those bolts have rubber backed washers. Yeah, it's a really nice ARF. I figure to maiden it tomorrow.
Their Extra 260 is the same size, reads like the Yak and pictures on their website suggest it's the same construction.
They've also got a 46-60 size Edge 540 that's actually about the same size as those two 60-size models. But it's lighter. I didn't see any interior pictures on their website, so got no idea what the construction looks like, but I'm guessing more than a 55 two cycle might be too much for it.
Give 'em a look. Those 3 planes fit what you're looking for to a T. http://www.aero-works.net/store/
