Kevin, I too liked the look of the Corvair at the Zenith booth. The fifth bearing
is a very neat and tidy installation. As always, William is great to talk
too as well.
As for the CH-750 kit, one point that has been missed is the match drilled holes.
The CH-701 kit is pilot drilled only. The CH-750 kit will be match drilled
(not too sure how much of it is though). This will save considerable time in
assembly. All in all, it looks like a really nice solid LSA plane but as a
Canadian builder, LSA means nothing to me right now.
I'm a scratch builder at heart. I'm into the home stretch on my scratch built
CH-701 and have no intention of switching to the 750 at this time. That being
said, I also plan on getting a set of CH-750 plans. I figure I'll wait a while
though as there will likely be a few corrections to the first generation of
plans. That and it will give my Visa card a chance to recover from Oshkosh.
As for O-200 prices, I spoke to Wentworth Aircraft from Minneapolis, MN at the
show. They say that a runout O-200 with accessories that is gauranteed to be
re-buildable is about $3500.00. A mid time O-200 will be $5500.00-$7500.00 depending
on time and condition. That is sure a lot better than a Rotax 100 HP
in the used market. But lets face it, factory new, the O-200 and the Rotax 912
ULS are pretty compairable in price at around the $20 Thou mark. Also another
point for the O-200 is that they are more plentiful on the used market than
the Rotax is.
Hope some of this information is useful to our group.

Any indications of how long the build time might be for the 750 in kit
form? Has the CNC element made an appreciable difference?

Very good informational post Doug with good back story tidbit's on the 0-20
0. The only negative thing I've heard regarding the 0-200 was the declining
avalibility of replacement and or repair part's. However, with it's reintr
oduction I consider this as moot now. I intend to shop around for a good re
buildable 0-200 for my own later use.

Now with respect to the CH 750 your touched on something I'd already though
t to do, which was wait a bit before ordering any plans as I've other fish
to fry for the moment, This does not mean I will not purchase 750 plans tho
ugh, far from it this is what I've wanted from Zenith and I'd like to do a
"scratch build" of one myself.

Lime said above the match drilled holes are huge! Cleco it up and rivet. Ok you
can check for burrs too and prime it too. I got the impression, though I didn't
ask outright, that it was deburred already. They told me the time for the750
wing build vs a 701 wing, but don't recall the exact number (
remember I'm building from plans so it does not matter to me) but it was in
the neighborhood of 1/2 the time I think. And if you think of all the time laying
out rivet lines, predrilling and clecoing and drilling to size and then finally,
riveting. It really sounds reasonable.

Hi Kevin,
I'm not too familiar with the "match drilled holes" phrase. Does that mean it
is drilled to it's final size and no further drilling is required?
Thanks,
Tommy Walker in Alabama

That is what I believe it to mean, due to the phrase, cleco it together and rivet.
But like I said I was more interested in the 701 so I was not paying too
close attention. But the build times, I remember made my jealous of 750 builders.
I should have asked more questions, but I'm sure all this will be on the web site
soon.
Hey Mark please chime in, if I'm all wet please tell me so, good info is good.
Poor info from bumbling sources like me is bad! [Laughing]

Match drilled holes means that the rivet hole are CNC punched undersize.
You have to cleco the parts together to check for proper fit. You then
drill (actually, reaming is better) to the final size, deburr, reassemble,
then rivet. Of course, you deburred the rest of the parts first and make
sure you use proper riveting methods (ie. don't rivet from one end to the
other). This saves the layout and jigging of structures and adds no
construction time.
This is the method RV's have been working with for years.
