Tim in Central Tx, contact MM directly, call or e-mail. He is very
informed, and has real experience in building these engines. Unlike Wynne's that
have broken cranks in mid flight, including nitrided crank ones. WW has
only developed accessories to Corvair engines, not the working guts that
really make an engine. When it comes to others who show knowledge of Corvair
engines for use in aircraft WW immediately jumps to criticize without any real
knowledge of what the other party is doing. By the way, MM can get the
parts, especially the cranks, and has one in stock. The others, the valve
covers and oil pans will be ready soon for sale, I saw and handled them. As
others have said, these cylinders have been used for decades, they are far
superior and weigh a whole lot less than Corvair cylinders.

Not only are some of the items from MM unavailable, I don't like what I
see about their coated aluminum cylinders. Almost all users of aluminum in
engine blocks use cast iron inserts. When cast iron is properly honed, with
the scratches running around in circles, they hold a slight film of oil,
which both seals and lubricates the cylinder-to-ring contact.
In contrast, aluminum can gall very easily in such applications, so the
user is dependent upon the durability of the coating to prevent this. I'd
want to know a lot about the durability in empirical testing.
With the fifth bearing, WW's stuff is about as bullet-proof as you can
get. If I were building the ideal, I'd go with WW specs, except for using
primary and secondary electronic ignition. Others have done variants of this
and can speak better to these mods.

Subject: Re: CorvairEngines-List: Corvair - where to get one?
I feel I have to respond to this post to clarify, as I understand it,
the positions Wynne and Magnificent Machine occupy with regard to
Corvair flight engines. I attended the Corvair College about a year ago
held at Magnificent Machine. I am a long time follower of William Wynne
who has devoted a very significant part of his life to the development
of a safe conversion of Corvair engines for use in aircraft. IMHO,
anyone planning to convert a Corvair engine for aircraft use should take
advantage of the testing and research he has done. His book, "Corvair
Flight Engines", contains a wealth of information about Corvair engines
and how to convert them. I wholeheartedly agree with all that has been
said about Magnificent Machine, but they, and others, are only building
on the decades of work that has been done by William Wynne.

A better source for good parts, like new cranks, light weight
cylinders, etc is at _magnificentmachine.com_
(http://magnificentmachine.com/) . I talked to him last
weekend and first met him in Livermore at a Corvair College. Wynne is
good but this guy has got even better stuff. You want fuel injection,
new not used cranks, etc. See this guy, he can build you a bullet proof
engine far stronger than any thing Wynne can build.

Mike,
While you are certainly entitled to your opinion, be careful of
representing it as fact. Patently false statements do no one any good
and makes the one who utters them look foolish.
No, I didn't have cool-aid today and I have nothing against MM aside
from the fact he started life as a knock-off artist. But folks change
when forced (or do they?) and attempts have been made to bring MM into
the fold.
The mere fact you would publish something along these lines indicate a
degree of naivety. Hopefully, with time, you will find that success
and failure patterns become obvious and perhaps one day it will be
clear to you, that what each of us believes, is true for us, even when
it is false.

WW's cranks didn't break. WW doesn't make cranks. GM does and people have b
een using them since the early 60s=2C when WW (and I) were in diapers. To s
ay that his cranks break is bizarre. If people are building new cranks or 5
th bearings it is because of WWs research and effort and the cooperation of
several high time engine builders who donated their cranks to be magnaflux
ed.
WW did not work out the guts of the engine. GM did that. The guts other tha
n the cranks work just fine and are readily available from Clarks.
How many flight engines has MM built? How many hours have been flown on the
se new cranks? Will MM sell you one without having flown it? If so that sho
uld set off alarm bells. If they fly it and build up some hrs and can contr
ol the quality it might be a very good product=2C who knows. Nobody yet.

You don't get the point. WW uses used parts to build these engines, even
nitrided cranks break. WW builds their Corvair engines with 100,000 mile
used cranks. And he doesn't guarantee any of them. If WW doesn't stand
behind its product then don't build them. WW engines, some with nitrided cranks,
broke.... Period! However, MM says use new parts, including rods and NEW
cranks. And that is what he is doing. I have seen MM's new engines, you
obviously haven't. The guts of these engines involve brand new parts, not
reconditioned ones. New is better than used. I've studied WW extensively,
talked to him, bought his stuff. As far as he goes it's not bad..In fact I
plan on buying some more of his stuff. But MM is raising the bar. If you
want to use 100,000 mile cranks, even nitrided ones, go ahead. I will use a
new crank that is 2 1/2 times stronger than an original GM crank much less
one with milllions of cycles on the crank.. I'll then be able to build an
engine without an even heavier 5th bearing. These engines are too heavy as
it is.

Are you speaking of the numerous crank failures of WW engines? To be
honest all he has created are accessories. There are plenty of builders of
Corvair engines who build as good or better engines. He has a bad habit of bad
mouthing others with little of no knowledge of the facts. I pointed it out
to a long time Corvair builder in Long Beach Ca who then called WW. WW
admitted his error, which error is published in one of his manuals in my
house, and WW admitted that he had no ral knowledge of any of the "so-called"
facts which led him to make the bald faced criticism of this builder's
proiduct. I have been to his colleges, twice, WW has excellent information.
But, I can assure you that MM is anything but a knockoff. And even if he is,
so what! Who says that WW is the only one to speak for the Corvair use in
light aircraft. He is not the summum bonum of corvaircraft engine building,
even if he thinks he is.
