Hi Paul,

Michiwa reviewed the HTML again and said all of it was translated except
some unreadable part describing the car's tires and chassis.

The Windows laptop arrived today. Soon the dyno software will arrive.  Sorry
I don't need Rhino (yet) to dyno the engine.  Definity after I start working
on the engine mount though.

For testing the engines I am thinking that the manual transmission doesn't
have the gear ratios needed for the prop.  Assuming that I am going to be
testing the Renesis engine down the road a little I am thinking about
whipping up a planetary drive of a three to one ratio using Matex's  LGU
146-M unit as a base.  It can handle a maximum torque of 55 Kg/M  (about
375ft/lbs)  and a momentum of inertia of 118.8 kg.cm2. at 146 OD. and 2.5Kg
unit weight

Question any foreseeable vibration problem with running the gears at
actually three to one reduction ratio?


Cheers.

Doug in Japan

Possibly. I have heard that certain integer ratios give problems in
that regard. You might talk Slauson Transmission into shipping a Ford A4OD
2.85:1 planetary to Japan for you. Cost over here is under $200.
