It appears to be a kissing cousin to a Avid Magnum, but without the flaperons. Kenny Schraders old company, who used to employ Troy, who went on to branch out into the Highlander after Kennys death. All share the same wing planform with minor differences, so very well proven.
I built one and flew it for 45 hours, about 15 years ago, (??) partnered up with a guy with more money then time (the opposite of me back then, and still). Great performer behind that Lycoming, handled well also. I remember it had a roll neutral thing: once banked up and in a turn it would stay there without much attention at all. Not a bad thing at all, it just seemed like most will want to go back to straight this was happy to stay where you left it. It climbed great, well over 1,000 FPM, and easily cruised 115 or so. Used more then twice the fuel of a 912S while doing so. I remember this as I had a dead stick landing in it, something about having too much air in the full system

We came in at 970 empty, with a full gyro panel.
Landed in the high 40's full stall, a lot of plane for the narrow chord wing, wasn't a Cub or a Rans S-7 as far as the slow end.
Louis up at Hart Aviation in Wrecksburg (Rexburg, an inside joke) flew it also, it was his brother-in-law's, fly on up there and pick his brain. I'm sure that the Frontier, while being different in details, is very similar, and I mean that in a good way.
