I finally found the source for drawings and photo guides for the O200 FWF installation. 

Go to Zenair's website (the Canadian location)   http://www.zenair.com/  and in the upper right search box on the home page type in the word password, then click Search.  On the page that pops up, select the first link.  That will get you to a page with links to password protected pages with downloadable files of photo guides and drawings for the 0200 FWF installation.   You will have to call Zenair on the phone to register for passwords for the sections you wish to access.  Phone number is on that same page.  They will send you your password(s).

There is no charge.  Email Nick ( zenithairnh@gmail.com) if you need assistance.

Tom, I was able to buy the baffle kit (which came with drawings) and the engine mount for the O200 directly from Zenith in Missouri.  Give them a call and confirm that those parts are still available for purchase separately.

Now, the other drawings and photo guides for installing the separate components I found somewhere on the Zenith site, either the Missouri site or the Canadian site.... not sure which.  I spend an hour looking for them last night but no luck.  I may have find them on another Zenith aircraft site, since the firewall forward O200 install is common to other Zenith models, not just the CH750.  I'll keep looking.  Between both our efforts, we should be able to relocate the download location.  There are a lot of files I downloaded (drawings and photo guides).  Maybe if you call Caleb at Zenith he can give you the webpage where those O200 files are located.  Let me know how you make out; I'll search again this weekend and let you know if I find them again. 

Email might be easier; my email address is beartrax at mtaonline dot net

Thanks, Tom, for the friend request.  I am more than half way finished and presently populating the firewall.  I installed a Continental C90 and am using the 0-200 drawings/photo guides.  I also installed a Cessna 150 exhaust to take advantage of the excellent cabin heat source (both exhausts).  It gets chilly up here in Alaska.  Yes, I'll have to make a minor mod to the cowl, but a small fiberglas blister added to accommodate the left muffler will not take much effort or time.   Good luck with your build and be sure to post pix from time to time. 

Tom - sorry for the slow response.  I'm putting a Rotax 912 in.  Just got the firewall foreward kit the other day.  Making slow but steady progress.

Thanks for the note...I had a rotax 912.  I put about 350 hours on her from 2006 to 2009 and then sold her.  My only engine issue I ever experienced was an ignition module failure. 701 flew as advertised and I enjoyed test flying, stol, and crosswind capabilities.  I have plans to the cozy mk iv...but may build a 750 first. 

Thanks for the friend request.  We have a used o200, zenith mount and cowl.  We may get the baffle metal from zenith.  that is the extent of our experience so far.  I learned at OSH that some, if not all, C150 exhaust will not fit under the Zenith cowl without significant and somewhat unsightly fiberglass modification.

Thomas, 

Thanks for the friend request.  I am building from plans and currently have the rudder completed and have most of the parts fabricated for the rest of the tail.  Since you are building from a kit I'm sure that you will pass my progress quickly.  I'm glad to have another builder near by and hope to be able to pick your brain in the future.

Tom:

Welcome to the group, I'm sure you will find this site helpful during your build.  I have a Rotax installed in my 750 and feel it is an ideal engine for this plane.  I like the UL engines but feel there are new and would prefer a proven engine.  Take a look at the new fuel injected engine Rotax now has available.  This is my first attempt at building an airplane and I ended up building the 750 without any outside help.  I have learned a lot of valuable lessons over the past year and a half, so if I can be of any help just let me know.  Your welcome to stop by if you like.  Your comment to me ended in my spam folder so don't get upset if I don't answer your questions in a timely manner.  I'll add you to my friends list.  Have fun

Ken
