I’m at the cowl fitting stage and the manual says “Temporarily bolt the cowling face positioning plate onto the prop flange.”

👀

What’s this “face positioning plate?” Is it something that should have been in the kit? Do I build it? Is there a template or blueprint of it, somewhere??

Thanks!

Never saw one in my kit or a template. I used the backing plate for the prop spinner to set my forward cowling position.

I think they are referring to something like this?

Yeah, that’s what it is. Did you build your own?

Just wished the manual said something like, “use the prop flange template, spacer, and spinner to build a positioning plate to create a 6mm gap between the spinner and cowl” before saying to install it.

Yeah I agree! Must be harder than you think to update the manuals? I borrowed one from a forum member. I will look but I think I have some other pictures on how to make one.

I too used the prop spinner.

Mounting the cowl. Page 18 says to install the lower cowl for radiator fitting. The exhaust is pre-installed on the 915is and no clear direction on where to cut the hole in the cowling for the stinger to pass through. Yes, there’s a scribed circle on the cowling, but it’s not to be trusted so says the manual.

Page 44 finally gets around to cutting the hole for the stinger and says to use the radiator as a reference point.

Which came first, the chicken or the egg?

😳🙄🤨

Any words of wisdom? Harlan, what did you do, here?

I found the answer in Harlan’s videos (thanks again, sir!): remove the muffler.

Just saw your post. Yes on removing the muffler.
Cut small and enlarge to fit when you do get to the exhaust hole.

Figured out a pretty good way to locate the hole in the cowl for the muffler. A 2x2 piece of cardboard with one straight edge to clamp/tape on the bottom of the radiator, even with the rear edge. Trace the outline of the radiator, cut a 6”x6” hole about where the stinger will come through, then cut a right sized muffler hole into a 9”x9” that can be taped down to the big template. Take off the template and cut where the front of the radiator is and line that up with the rear of the NACA duct and that’ll get you within a 1/2” of where the hole should be.

The pictures make it easier to understand.

That carbon cowl looks great. The exhaust hole lined up well. Bet your glad you don't have to fix or re-do that cut!

The cowl fitment portion of the build sucked a lot of life out of me as it has to go thru dozens of fit and cut cycles.

Yours is looking real nice!
