CorvAircraft> Fuel injection for Corvairs

[AVLEC]

John and all,
This topic is a very touchy one and could possibly end in a lot of people
unsubscribing but I think that we as aircraft and aircraft engine builders
should be mature enough to handle these things in a mature fashion without
getting all emotional about it and doing things we might regret later on.
Having said that, I agree 100% with what John has said. I was the one who
got flamed from every conceiveable angle over the electronic ignition saga.
As John said, the system that I advocate hasn't been flown on a corvair yet
but has at least 1500 trouble free hrs that I know of on engines such as
type1 VW, type IV VW, 1/2 type IV VW as well as a 1600 Honda auto
conversion. I also flew about 8hrs with a friend in his type IV VW powered
KR2 equipped with one of these systems. I bet there isn't a sweeter running
VW motor anywhere, just ask Serge Vidal who bought the plane from my
friend.There is no reason why it should not work on a corvair. I received
many private emails from both WW as well as from many of his deciples
telling me how the system was flawed. One of those people was Clare Snyder
who's main gripe was that the system woukd be succeptible to voltage spikes.
I just read a post by him stating that modern electronic systems are much
more resistant to such things.   So I guess it boils down to who is
advocating it.
What has changed in the meantime? The only thing I have noticed is that WW
is now doing some testing on electronic ignition so now it must be ok to do
so. One of the people now involved in the testing of electronic ignition
with WW  refused to try a system that I offered to send him free of charge
then. WW led everybody to believe that he had tested and rejected just about
everything called an electronic ignition. As it turned out he had tested
five, none of which were of the type that I suggested.
This list , besides being owned by Mark L, should be equally open to anybody
who has a contribution to make (within reason). If we can build and fly our
own aeroplanes, we should be able to decide for ourselves what we put into
them.
By the way, I also received many private emails from list members who shared
my concerns with the WW system and requested more information. These
individuals only contacted me privately because of the inevitable flaming
from the loyal WW deciples that follows. This is not a healthy situation and
something should be done about it. I agree that WW produces good quality
products that ,as he says, he has flight tested but to say that his way is
the only way is just plain short sighted. I will say one thing though, he
sure can talk himself out of any tight spot.
Just my humble opinion for what it's worth
P.S The bit after my signature was trimmed of the chaff.
