The Revmaster has a starter, dual mag and alternator on the flywheel end. I would
hate to give up all them nice features. Thanks for the thought Larry. :?

The problems with material lists:
1. The efficiencies of various people in their "nesting" aptitude will
greatly effect the amount of material required. The amount of waste is
rather unpredictable in this regard.
2. If Zenith does specify a quantity people will jump on them because
they ordered short or long on their quantity which in turn costs the
builder money (didn't order enough and incurred additional shipping
costs or has to order too much and extra material they don't want/need).
I do agree there should be a list of materials with approximate
quantities with the stipulation that "your mileage may GREATLY vary."

on the ch701.com site there is a pdf-and dxf file that has a breakdown of
the materials needed it is drawn onto the sheets as to how to cut for best
use.

Hi Ken. Your question was well timed as an 'ol Yukon trapper/ pilot
who plans to build a 750 and myself (701 half done) just had a long
jaw about this topic around the shop wood stove. Our discussion was
more based on how to warm up our engines when we overnight in the bush
or at a strip without power but some of these topics may (or may not)
be relevant for your application.
A lot of planes in the north are equipped with electric pre-heat units
from engine manufacturers. Basically electric resistance heaters
mounted on cylinder heads. Boring, expensive and not very useful on
remote strips or bush flying (unless you find a "current bush":)
More important, these heaters do not heat up oil in a dry sump engine
(need extra heater on oil tank).
An engine blanket (the pilots sleeping bag or coat) thrown over the
engine for shorter stops keeps sufficient heat in the engine for 3 to
12 hours (temp dependent of course) to allow starting and greatly
improves the efficiency of any heating devices.
Bush pilot favourite - drain oil when engine is still warm into a
billy can. Keep in cabin (or in your sleeping bag - honest) until
ready to fly again or reheat billy can over fire or stove.
My favorite - use semi-synthetic arctic grade oil. Shell
literally spent millions developing extreme cold climate lubricants
for use by the oil and gas industry in the arctic but the products
have never seemed to catch on with general public or other
industries. My local bulk POL plant has been great in providing
extreme cold weather lubricants that meet or exceed manufacturers
warranty requirements. I simply send Shell oil specifications to the
engine or vehicle manufacturer and they approve their use. For
example I have been using semi-synthetic 0W-40 for about 20 years in
all my vehicles including high compression (diesel) and high
performance, high compression (turbo subaru) with excellent results.
My turbo subaru starts at temperatures down to minus 40 without
external heat sources. Icing on the cake is that the semi-synthetic
oil is half the price of full synthetic.
Please note that I have not sent the shell specs to Rotax for
approvals yet.
The last option is probably the best (IMHO) which I plan to use in
conjunction with semi-synthetic arctic grade oil.
Espar makes micro turbine diesel and gasoline heaters for transport
trucks, boats and heavy equipment. These units are awesome (had
one on my sailboat). Not much larger than the size of two paper
back novels. The smallest unit (5 lbs weight installed) draws 8
watts on low and 34 watts on high with a 12VDC source and burns 0.1
liters per hour on low and 0.28 liters per on high. Output on high
is 2200 watts (about 1.5 times a normal household electric heater).
Although it burns diesel a one liter tank provides 4 hours continuous
operation. They have a gasoline version but the smallest one
weighs about 20 lbs.
The reason why we both like the Espar heater because it can be easily
plumbed into the cabin air heating ducts and will heat the engine,
fluids and most important - the cabin and will run for days on the
aircraft battery. My friend also showed me how to start an O-200 by
hand for backup in the bush (batteries also lose their efficiency in
the cold).
I believe another manufacturer is Webasto.
We are working on a cell phone activated remote control so we can sit
in the airport cafe drinking hot tea or snug in our beds while our
plane seat cushions get nice and toasty.
If you are interested, I can keep you posted on the results of
enquiries to Shell and Rotax.
Warmest regards

Geoff,
Once you crimp the connector on the wire, I added a dab of solder, you can insert
it into the connector without taking
it apart. It will snap in place just make sure you have it all ready, it will be
hard to take it out. Don't forget to slide the
grommet over the wire first before crimping.

up
Geoff,
If you don't get an answer here, I suggest you address this question to the
Rotax group (rotaxengines-list@matronics.com). You will need to join that
group just as you did with the 701-801 group.
