Hi Dan,



Thanks for the link.  I read the section you mentioned and decided he 

is probably not talking about me.  There must be other detractors who 

fit the profile he describes as "Only built a rudder" or some such 

thing.  I am on my second airplane.



I was glad to see his comment:

"For many builders, the mere fact that I've relentlessly pursued 

providing them with an affordable powerplant option in a marketplace 

dominated by expensive products earns their solid gratitude"  This 

addresses the only problem I really have with Mr. Wynne - the notion 

that there is some value to his engines beyond their low cost.  He 

apparently doesn't make that claim, but his followers seem to think 

it provides highly reliable power and has other high value 

qualities.  This is in direct conflict with published studies that 

show uncertified engines have 2 or 3 times the failures as certified ones.



Mr. Wynne wrote to me twice in the last year to argue over my 

comments on his engine and followers.  In the first one, I felt he 

was quite rude.  The second one was more polite but did make some 

personal attacks on me based on the fact that I am still working on 

my wings.  I don't know why he feels a need to write to people who 

question his work, but he seems to think it is a good idea.  I find 

this even more odd since he is not a list member but responds to list 

posts anyway.



My other big complaint is the fact that I have received many personal 

attacks because of my questioning the value of the Corvair conversion 

engine.  I guess this is a case of "If you can't attack the message 

then attack the messenger."   Likewise, I have received many 

rebuttals that cite what a great guy William Wynne is but don't 

address the technical issues raised.  I am sure Mr. Wynne is a very 

nice guy - at least to those who are impressed with his work.



I feel the Corvair conversion engine (like other auto conversions) 

has a place in experimental aircraft. They allow a builder to get 

airborne at a very low price compared to certified aircraft engines 

and probably at a somewhat lower cost than using purpose built 

aircraft engines like the Jabiru and Rotax ones.  If the builders 

realize they are trading performance and reliability for price then I 

have no objection at all.  It is only when I hear that these engines 

are superior in performance or reliability as well as lower in cost 

that I feel a need to object.



I guess I better put on my steel cup to protect me from the personal 

attacks this post will bring.



In any event, I appreciate your reference to the web page.



Best regards,



Paul

Have you read William Wynne's Thursday night update at

near the bottom of the page.

Hi Frank,



Your autopilot solution is great for someone willing to bet his life and

his passenger's life that some computer software can fly a plane better

than he can.  For me, a good gyro or two sounds a lot more attractive.

Paul,

I have to agree, the studies and data do bear out a more difficult set 

of numbers for the uncertified

engines, but they offer as much more in economy and performance as they 

require of the builder that

installs one.  The person that selects the automotive engine needs to 

have a pre-defined sense of what

is required to make the engine work satisfactorily in an airplane.  It's 

not as much the engine as the

builder that is responsible for the statistics we see.  Those that 

succeed gain much more from the effort

as well.  Being a non-engine guy, I fully appreciate the complexity of 

the novice builders decision for

or against the certified engine.  It isn't just which one anymore, but 

how it's best done.

 

I believe there is no trade off in performance or reliability if the 

Corvair or Subaru installation follows the

path taken by successful history provided by Mr Wynn and others.  The 

poor statistics only serve to remind

us of the people who made shortcuts, didn't appreciate the problem, or 

didn't follow the obviously available

good advise from those who have done it so well.



Mr Wynn is perhaps terse at times, but he's got hold of a great engine, 

made it worthy, yet has to contest each

and every other ego out there that says they're going to change 

something against his advise.



This is not an attack of course, but perhaps a better perspective is 

that it's not the engines, it's a people problem.
