Well guys, here's some pictures of the project. If we can ever find
time to work on it....
Our solution to positioning the motor accurately involved replacing
the
Oil pan with a load bearing plate, indexed to another load bearing
plate
underneath, and supported in 3 locations by 2" bolts acting as a
small
screw jack. Maybe the picture explains it better.
We've also been putting spars in wing skins and amassing parts to
make
the motor go. The bell housing is the original made by our own
George
down under...The prop is by our resident rotary ducted fan expert
Perry
Mick. Redrive is Tracy Crook, of course.
We're moving to be closer to the project, and hopefully we'll be able
to
be at Tracy's next year.

Hey thanks for the pictures Chris.
What does the bell housing weigh Chris?
Looks like you need some volunteers. Anybody want to move to Salt Lake
City
and work on a fun project?
BTW Chris what happened to the web site with the pictures of the
plane?
Paul Lamar
The bell housing weighed 13.6 pounds when we started. we had to do some
additional machining to get it to work right with Tracy's redrive and a
Mazda starter.
The website, broken though it is, can be found at mk1studio.com. It's
Matt's robotics site, but at the bottom is an aircraft link.
I hesitate to ask for help from you guys because I know we're all
busy,but....if anyone were to say, have extensive experience in a 3D
modeling program and would like to put together a firewall forward view
for us, we could work out a rides for help arrangement. Like from So
Cal to Florida, for example. Maybe even during the month of October.
Firewall, 44" wide X 28" tall...

That is not so bad on the bell house. A bunch of three inch holes ought
to take out another couple of pounds.
No problem on the 3D Chris. Where is the engine thrust line?
I assume the hard points can go anywhere on the composite sandwich
firewall.

Paul,
That is the original prototype - it is a little heavy due to the internal
ribs with integral lower mounting points - it is however very strong and
ideally suited to the application where weight isn't so critical.
The extra machining Chris mentioned was because my original advice on the
diameter of Tracy's PSRU must have been on the small side and he had to take
out a little more and I believe the seal well had to be a little deeper.
Also the starter is different than what was originally thought.
I am delighted to see this on Chris's Aircraft!!
