Hey Ted,
Thanks, as always, for the insights. Always good stuff.

I just wanted to add a little to something you mentioned earlier:
I am an absolute nut case on adapting a stunt ship (and all of its paraphernalia, especially the handle--the interface between the pilot and the machine) to the desires of the pilot. I believe that flying thousands of flights on a poorly refined airplane system so that you can predict the required inputs to get a good output is an inferior way of becoming a winning stunt pilot. Yes, it can be done the other way around and Jimmy was pretty much the poster boy for doing so. He flew thousands of flights on numerous ships in less than state of the art set-ups and trim and competed with the very best. Jimmy felt...and was probably correct...that flying those many gallons of gas were necessary to be competitive. I would also note that he was quite open about having to build something like thirteen airplanes over the space of only a couple of years because they "broke" on a regular basis.
I just wanted to address this because it sounds here like "Jimmy didn't know how to trim an airplane". He did ... he was just trimming them in a way that most of the East Coast guys were trimming planes in the Eighties. Namely, make the plane nose heavy, so it'll "groove" and get a harder corner - that was the philosophy being espoused by a lot of top fliers in the area then. Jimmy wasn't the only guy then doing this either - Glen Meador trimmed this way, I believe, and so did Lou Dudka, and Bill Simons, and a whole lot of other talented fliers. Windy was the only top flier back then I can remember at contests in New Jersey who had tail heavy airplanes. Even Bob Hunt mentions this in the "Saturn" article as this was how he trimmed ships for a long time, until he began flying more with Billy Werwage and adjusted how he trimmed airplanes. I think this is why many of the designs from that era from those guys had big flaps, and big tails.
You can argue that this is the "wrong" way to trim an airplane - or, at least, it's certainly a more inefficient way of trimming. But it's how it was done back then, at least in parts of the East Coast.
Also ... well, to be perfectly honest, even if Jimmy was flying Brett's Infinity, and it was in perfect trim, he
still would've flown a bajillion practice flights with it. That was more an aspect of his personality, rather than a need to better trim the airplane (although sometimes it worked out that way). I remember watching him lots of times at the Nats with his coach Keith (my dad) and we thought the airplane was perfectly fine as it was ... or at least it was as good as it was going to get. But Jimmy was always convinced that with a couple of more practice flights, it'd be even
better.
The few times he decided he didn't need more practice, he'd get antsy, and decide to put up "one more practice flight" anyway. Were these flights always helpful? Probably not, at least in terms of the plane flying better ... but he always felt way more confident with a ton of practice flights under his belt, and I do think that translated to better scores.
I do find it kind of interesting to see how the electric planes are trimming out more nose heavy than their IC counterparts. If Jimmy ever came back to stunt, I think he'd do really well with one.
