 |
|
For those considering an alternative engine to the Rotax 912. The Smiths
of Valley Eng/ Culver Prop. have come up with a complete firewall forward
package VW engine redrive, Culver Prop, engine mount, Nose bowl package
for the Zenith CH701
Or you can buy the engine mount or any of the things listed separately.
http://www.culverprops.com/zenith-701.htm
All the info is on their most recent web page.
But they don't do email very well,,,,,,, For pricing and detailed info, it
is best just to call.
Larry has shipped out several engine mounts already....... I want to
caution folks on this....... Larry's mounts fit the 701 Rotax mount points
EXACTLY as shown in the back of the CH701 plans..... the only exception is
the nose gear strut mount has to be trimmed slightly a few more degrees
than shown in the plans........This is the thick alum piece that mounts to
the top of the firewall and and holds the nose gear strut.... One person
didn't realize the this piece needed to be beveled at all he thought it was
supposed to be square at both ends............. Another builder put his
lower alum angle longerons on backwards. meaning the angles were pointed
the wrong way, from what is shown in the plans......... when they are
installed incorrectly,,,,,,,,,, even a rotax mount will not fit...........
the bottom engine mount attach points fit inside of these alum angles on
each side..... they have to be orientated in the correct manner as shown on
the plans........... Another potential problem......... DON'T drill the
engine mount holes in your firewall till you get your engine
mount.......... One guy did and missed the holes by 1/2 inch from what the
plans call for.........UPPS,,,,,,,, nothing fits now........ one off custom
mount is the only option no matter what engine he goes with.......
One of the 2276cc VW engine redrive Culver prop packages is flying in
Idaho, a Dr Arbo, I am not sure he is on any mailing list, but with
several hrs of test flying he has told the Smiths he loves the Engine
combo........
Over the next year several more are going to be flying with this
combo..... and I will report back when more info comes forward....
Another Valley Eng, 1915cc VW engine and redrive combo is flying weekly at
Eldon MO......... B.J Swallers' pictures of that setup are on the Zenith
builders gallery
B.J. and the local pilot (owns the hangar the plane is stored in) loves it
too.......

I talked with Larry Smith's daughter via email today to see if they had any performance numbers yet with the Culver Prop/Valley Eng. package. Excerpts are below. Those of you who have been shunning VW powered 701s may want to take another look. Rotax and Jaburi look out...
PIREP from Marshall Arbo in Idaho:
" The plane gets off the ground before I can get the throttle all the way in. Approx 30 feet on a 90 degree day and altitude of 2320'. It has a climb rate of approx 1400 ft/min from 2320 to 5000ft and that is as high as I've been. I only have about 5 hours to-date on the plane. "
From Larry Smith:
" He had a gravity fuel system, so when he really got to testing it he climbed at such an angle that he starved his engine for fuel and it died on him, we sent him an electric fuel pump and he has been doing fine ever since."
