| Subject: | Fund Raiser List of Contributors - Please Make A Contribution |
Today!
Each year at the end of the List Fund Raiser, I post a message acknowledging everyone
that so generously made a Contribution to support the Lists. Its my way
of publicly thanking everyone that took a minute to show their appreciation for
the Lists.
Won't you take a moment and assure that your name is on that List of Contributors
(LOC)? As a number of members have pointed out over the years, the List seems
at least - if not a whole lot more - valuable as a building/flying/recreating/entertainment
tool as your typical magazine subscription!
Please take minute and assure that your name is on this year's LOC! Show others
that you appreciate the Lists. Making a Contribution to support the Lists is
fast and easy using your Credit card or Paypal on the Secure Web Site:

or by dropping a personal check in the mail to:
Matt Dralle / Matronics

I would like to thank everyone that has so generously made a Contribution thus
far in this year's List Fund Raiser! Remember that its YOUR support that keeps
these Lists going and improving! Don't forget to include a little comment about
how the Lists have helped you!
Best regards,

Your right Roger, that is why I have 2 50 watt pads on my crank case. What I
have done is like the Reiff preheater for the 912 engines.
http://www.reiffpreheat.com/Rotax912.htm
I also put a blanket around my engine so that it keeps the heat in. The only
difference with the Tanis system is that you have the bolt heaters in each
cylinder. I do like that but am not willing to pay $650 for it.
I do not live in a real cold climate but I find that even when the engine is
around 50f it starts harder than when warmed up. The other day that was the
case. Hanger temp was 50f, I had the heater plugged in all night, it had
been 2 weeks since I had been flying, the engine started like I had been
flying it all morning.
I believe any time you can get the engine closer to operating temps on start
up, it is a good thing. So I will plug in the heater the night before
anytime I go flying. Even in the summer.

Hi Guys,
Before you think you have done a good preheat job read this article.
Just warming oil does not preheat a system. Metal parts expand at different
rates. There are a couple of factors.

As far as those bolds that are replaced in the Tanis system, this is what
Reiff has to say about it: quote from their web site.
A big advantage of our system is that it is non-invasive. All our parts are
installed "on" the engine. Nothing is installed inside the engine, and you
do not need to remove any Rotax parts or replace any Rotax parts with our
parts. For example, one competitor's system replaces the Rotax intake
manifold bolts and a crankcase bolt with their own heated bolts. These are
simply hollowed out bolts with heating elements epoxied into the hollowed
out core. As a general design philosophy we feel it is safer not to replace
parts that were installed by the engine manufacturer, especially critical
structural parts like bolts.

Tanis is approved by Rotax for those bolts and they are not structurally significant
bolts. Any thing that you can do to get the entire engine warm before a
cold start is good.

I live in a place where the temp varies from -20F to 100F.
I am also using electric heating pads from an amazon eShop.
Heat spreads through metal very similarly to electricity, after enough
time most everything gets warm.
Personally, I would NOT put too much stock what Rotax suggests
regarding 3rd party products. Cross marketing endorsements often
have more to do with under the table financial arrangements than
just the engineering.
Just look at the history of approved and delisted engine oils. Honda
oil never made the list because they make competing engines, for example.

It is funny you should say that because with the Tanis system, you can only
buy it from a Rotax dealer. All the other systems they sell, you can buy
directly from Tanis. I am sure it works great but my 50 buck systems works
great too. $650 is a rip off in my opinion.
