Anybody selling a 20B pusher mount?  My velocity airframe is  complete(!)
and i am gearing up for engine and instrument install.  Al Gietzen
modified a Franklin mount, but my welding skills are...subpar, to say
the least.

Also, I have decided to go turbo, not supercharger.  What turbo did  Tom
Parkes use on his ES and what is the latest version of the
turbocalculator spreadsheet program?

Jerry Hey can build you a motor mount. Make a sketch of the
firewall hard point locations and the distance from the firewall
to the prop flange. We have a few designs but we need to double check.

Do you have your turbo and water cooling plumbing decided? You should
do that before a motor mount can be designed and built. Here are a  few suggestions. Do you have 3D drawing capabilities? If not I  suggest making
foam mock ups of all the parts and located them before proceeding with
the motor mount design. I'll do a 3D for free after you decide where
you want to put things and you have a turbo manifold and waste gate
chosen.

Tom Parkes can answer the turbo question.

Here is Dave Leonards turbo calculator but I am not sure it gives
you enough info to insure the turbine will live under aircraft  conditions.
At least half a dozen car turbos have been destroyed so far.
You are much more likely to get the turbo to live if you use an
aircraft turbo. It's a long story but car turbo charger can be  modified
to slow the turbine so they will live. Easier to find an aircraft  turbo
and use it.

Paul, are there excellent SolidWorks files available such as a
tractor driven unit 13B that I could adapt to a super cub/Patrol
frame?.  We have solidworks, and if there are some time saving work
already done, I would provide feed back when a new or different mount
would be drawn up.

The drawings/modeling of the 20B for the pusher were good and made me
think there was others already out there.

Sure Scott. The files are too big to email so I will set up a download
area on the web site with a stp file.

RV4's are about the right width so one of these might work.

I'll take the RV4 landing gear tubes out.
Give me a day or so.
