Paul,

Seeing Richard Sohn's report on the single rotor in which he
achieved an acceptable idle with a six inch intake forces me to
the conclusion that I need a test stand badly.
Granted a test stand is a long way from a dyno, but still a lot
of intuitive data can be gathered. We can observe static rpm
performance with different length intakes for example.

What I am looking for is a simple, cheap stand that I can test
run my engine on. I am hoping that someone has already designed
this and has some practical experience running an engine with
prop on the ground. Can anyone provide a schematic of what a
test set up would look like. Where is the fuel. the instrument
panel, etc. I have plenty of room next to my shop and could
easily build a shed roof over the test set up.

Richard Sohn, come to think of it, must have a test stand. Maybe
Lynn does too. Tracy? Photos, plans, advice? All would be
appreciated.

Thanks, Jerry

It is almost as easy to make a dyno as it is to make a test stand.
This would be a pieces of cake for you. You don't really need to
measure the thrust. That is handy to test props but not really
necessary.

You did just get that message I just sent did you not?

Everett Hatch used this type of dyno and I think Power Sport still
uses it.

Paul-

We're also terribly interested in a home-made dyno.  We intend to
run our fwf extensively on the ground before we install it into
the fuselage & had been intending to do so with only a simulated
prop load.  But if we can get a dyno set up...

Thanks Mark for all the work you did on the DVD's. Have not heard from
Bob White yet on being able to download the mpegs from his web site>

Hi Paul,

I though I had answered that.  Everything will be available from the
web.  I will put together a web page with a link to each video as time
permits.  (The clips will be available without the web page.)  If you
have sent the CD, I haven't received it yet.

I sent it last week Bob. Apparently I had the wrong address.
Please send me your address again putting the word private in the subject box.
