Rick, Group

Contrary to Ricks suggestion, why not post the replies to the list?

I am sure most of us who are not flying would be intertested in a good
discussion on the tech details of the engine / prop (pitch / dia / fixed
or variable/CS etc.) installation as well as the merits and benefits of
things like wheel pants (like, is it worth it, how much speed gain?).

This info will be a big help in making those decisions as time passes.

My .02!

Thanks

Dear Fellow Rebel builders;
G'day from "Down Under"....(Australia).

My wife and I are building kit #541 down here in sunny OZ (Sydney to be
exact).
We are looking at completion within the year (fingers crossed)....and we
need some guidance as to what engine to fit to our Rebel.

We have been preparing an alloy V8 engine to date, but we now suspect that
it will be too heavy and eat into our usefull payload unecessarily.

We would REALLY like to hear fron builders who have COMPLETED their Rebels
and are flying them / have flown them.
If you could possibly answer a few questions and e-mail your answers back
to us, we would be very grateful.

1) What engine / engine and reduction drive did you use ?
2) What horse power is it rated at ?
3) What is your propeller diameter and pitch ?
4) What R.P.M. do you cruise at...and what airspeed does that give ?
5) What is your maximum airspeed attainable (in level flight) at what

R.P.M. ?

6) What is your empty weight (the planes',..not you personally) ?
7) Have you bothered to fit wheel pants and / or other streamlining

devices ?

Do you feel that you NEED more horse power from the engine ?

### If you know of any Rebel owners who are flying but are NOT on the

"net"..

...could you also possibly ask them to answer theses questions for us and

send

their answers in your return e-mail to us please ?!

Sorry to bother you all with theses questions.....but we are rather

isolated

from the mainstream of avaition down here,..and we would love to find
out first hand what we need in the engine department from other Rebel
builders.
To date there are only two Rebels flying in OZ...one is the Australian

agent

who has fitted an 0-235 ..115 HP Lycoming , and the other has fitted a

Rotax

912, 80 HP. Both of these builders live about 800 miles from us...(we

don't

get to see them often ,as you might well guess).

We PROMISE that this will not become a regular/repeat pain like our friend
Mr Dan Morehouse !!!

Thanks for your help !

Bye for now.....................................Rick & Wendy Harper
