Welcome! For the
few years, I've been
designing my own plans to build a scale B25-C Mitchell
bomber. The design was completed using SolidWorks, a 3D
modeling program, and WinFoil. Construction
of the first prototype began on Sunday, March 6, 2005.
Click on the links to the left to view the different
sections of the construction. As soon as the prototype
is completed, and corrections made to the design, plans
will be available for purchase. The completed plans will
be available on paper or on CD-ROM, .dwg format,
so you can send
them out for laser cutting.
If you have any questions or comments, feel free to
contact me at

A few
items to update:
1. Plans will be available soon -
hang tight. They will not be in color
as the printout/drawings were not as clear as I
would like them.
So, it's back to black and white.
2. The glow plug wiring was replaced with
20 gauge stranded wire
and the glow plug batteries were replaced with 5000ma
NiMH.
With good flying weather here in Wisconsin,
Precious Patty re-visited
the Sky Ranch Flyers field on Tuesday, May 6th
for engine testing, which was halted after just
a few minutes because of a fractured
engine mount! Repairs were made over the
weekend, and the bird
should return to the field tomorrow.

Not
much has been happening with the Mitchell. I am
continuing to finish up the plans for release,
and am trying my best to have them done by the
end of March 2008.
To
keep your interest in this project, I am
offering a download of the port outer wing
drawing, in detail, full scale (click
here).. The file is a .PDF file, so
you will need Adobe Reader to view it.

As
the snow begins to pile against the window,
Precious Patty is now indoors, back in the
workshop. We finished burn-in of the Saito
engines and tuned them up, and have completed
the re-wiring of the Twinsync sensors on the
engines.
Click here for the pictures.
We will be doing one more balancing and weight
check in the next few weeks, then we will be
finishing up the plans for release.
Also, a big "Thank You!"
to my friend Gamza Davis from Cape Town, South
Africa, who warned me the other day that the
website was down!

After
much frustration, the Thunder Tiger .91
four-stroke engines have been retired and
replaced with Saito 100 four-strokes. Yes,
this is probably way too much power for this
plane, but was an easy replacement as it need
minimal alterations to make the engines to fit
the existing mounting. First start of the
Saito's took place Monday night, with 24 minutes
of run time on each engine.
Also, I will be re-wiring the
Twinsync sensors
when the new ones
arrive from Bill Wilke. I don't have the
heart to start drilling holes
in new engines, so the magnets will be mounted
in a plate behind
the propeller, much like mounting the magnet in
the back of a
spinner hub.

Engine testing was done Thursday, October 18th,
at which time it was decided to "retire" the
port engine. It was still acting stubborn.
Fortunately, I had one more engine I was running
on a large trainer,
which is now on the B-25 and appears to be
running good.
The
2nd flight of Precious Patty was postponed again
as of Thursday, October 18th, as during the
engine testing an unusual noise, similar to
"static", was coming from the back of the plane.
Closer examination
showed the horizontal stabilizer was fractured
mid line and wasn't
detected at first as it was hidden by a cosmetic
part of the plane.
So, this weekend, a re-design was done and a new
stabilizer was
built. Jon Pryga is going to paint it
Tuesday, and then we'll continue
to the field.

9.10.2007 Running out of time, I called in a professional
- professional "Grandson" that is.
Meet my grandson, Mason Kell. At 5 years old, he is "big
time" into Airplanes.
Here we are fiberglassing the hatch covers for the forward
steering wheel.
