This is very interesting info on the history of this type of aircraft.. thanks to all that shared that. As far as flight of the RC versions.. I can only speak of my experiences with my own aircraft.. and really it is in generality, and my own personal preference. Each owners aircraft is going to be obviously different, and varied.. and that's totally cool.

I do invite anyone's opinions/experiences with thier finding on that sub-topic.. not to get off topic at all.. I think its well within the original topic.. sameness or differences in flight, one plane to the next, and experience is how we learn.

Maybe a bit of an interesting note here.. I seem to recall reading that the first series of Extra's(WalterExtra) borrowed the wing from one of the Cap aircraft.. that's a vague memory, but if anyone has insight, please share..

Somewhere I found out also.. the Midwest Extra300 and the Midwest Cap21 share an identical wing... I actually own a Midwest Extra.. and from what I can tell.. it is the same wing.. but has anyone had both, and can they confirm my suspicions?

Again, I don't mean to take this off topic at all... but these are also questions I've had about similarities/origins.. I do think I'm an UnlimitedAerobaticJunkie.. So any info is appreciated. Thx.

PS... don't forget to rate the original post... It was a very good question.. high rating in my book.
