I am not sure which Zenith this is then. The 801 is the high wing  STOL
right?
This may be for the  ZODIAC XL/601. Somebody said all Zeniths were   the same
firewall.
No problem changing it. Notice this is for a one rotor LSA. Are  you  using a
two rotor?

I dwgs are preliminary so I was planning on using that top center   hard point
for the rear motor mount using a strut arrangement similar to this.

The rad may fit under the engine. Two rotors require a rad about  600  cubic
inches no more than 2 inches thick. That implies a rad core about   18" by 18"

Well, No I didn't say all Zeniths shared the same firewall, what I   said was
that the CH-640, and the CH-801 Stol shared the same firewall (as   well as
the certified AMD 2000). The only difference from 801 to 640 is  the  top
center reinforce present on the 801. The 640 being a low wing  design  doesn't
have this feature. I hope that I have cleared up the confusion.
I have no information on the 601 or 701. they may share the same   firewall
design between each other, or not.

One needs a menu to keep track of all these numbers :)
What is the difference between a 701 and an 801?

I don't see any top center upper hard points on these two Exploded   Views
of the 801. I just got these off the Zenith web site.

Here is a picture of a Rotax engine mount for the 701.  Use same hard
points for RotaMax.   I think the 801 is the same only larger.     Jerry

Which one do we need first. So the 701 has the upper hard points.
Ok what are you going to build next? Twin Rotamax or single Rotamax?

How many ways can I say it.  The 801 is the one.  It will be powered
by a Renensis.  Later, please do a 701 RotaMax for me.

OK
