I have long considered 2 direct -drive air cooled engines on my CH-701...
Does anyone have experience proping a Corvair?
Not looking for opinions from those who do not.
I have proped C-170 & C-182 and that is not too difficult. I would
consider using a Corvair if I can eliminate the starter wieight and keep
in down to the reccomended installed weight that Zenith specifies
185lbs max is what I think they say.
And, yes i know you would have to use other things like their newer
lighter rear mounted altenator, and maybe the Precision Injector
carb(carb heat not needed),the lighter 64-65 heads etc,etc...But it
seems very doeable. I would consult WW for all proven products in this
arena..

Many Corvair-powered planes are hand propped. See the Pietenpol list on
this server or the WW manual. You still need a battery to run the
ignition but hand propping is not a problem.

This is why this list can be so darn frustrating sometimes.
Question from list = " Does anyone have experience propping a Corvair?"
One responder says...
" Short answer.... you can't prop a corvair"
Another responder says...
"Many Corvair-powered planes are hand propped."
On a different topic but still to my point - the other day someone tells
me in response to my question...
"Not trying to be a smartass but have you tried measuring it? "
The answer to the above is "yes" but I thought someone who had "been
there done that" might have a quick answer. So effing sue me.
Lycoming ultimately gave me the answer I needed. Their customer support
was awesome.
I have always done my best to provide useful answers when I had them
(have I been able to help you Carl?) but most of the time I don't answer
(or will only answer in private so no value to the full list) because I
don't want to get contradicted by another person's answer or flamed as
shown above. No one likes to be made to look like an idiot in public.
In the "propping" example only one of the answers can be correct. How
is anyone supposed to take any value from two such opposing statements?
The only prudent thing a person can then do is find independent
validation. Even though that is a prudent thing to do no matter what,
it certainly was not the point of the original question.
The best advice I can offer is to find a group of friends or other
builders whom you can trust to provide valuable information and only use
the list as a fallback.
There are also some great vendors out there who will really go the extra
mile and help with questions you might have. A couple that come to mind
right away are:
For excellent custom fuel and brake hoses >>>
steve(at)aircraftspecialty.com
For excellent products and help with wiring your Panel >>>
http://www.compositedesigninc.com/
Custom Grips for your control stick (and other cool stuff for your
project) >>> http://www.mrrace.com/
Custom Exhaust System >>> clinton(at)customaircraft.com
Build safe everyone.

Steve I stand corrected .... I don't know where I heard it or dreamed it but after reading a bit I found you can hand prop a Corvair but have never had the need or desire to do so. As you know you can hand prop a Lycoming but not with fuel injection.....LOL I thought once of building a motor like they use on model airplanes to start them from the spinner but quickly came back to reality....

<< Afterfxllc(at)aol.com >> Is this Jeff?
Anyway…
Thanks for clearing this up. That should put the propping a Corvair issue to rest but does not resolve the underlying challenge we all run into.
As I go through my second build I constantly run across questions I am not qualified to answer because I am not an A&P, trained aircraft designer or assembler. Anyone who thinks they are just ‘cuz they successfully completed a project and the FAA gives them a Cert for their airframe, engine and they know how to twist a few wrenches might one day find themself in a very challenging situation. There are some pretty dangerous personality types out there. I think we are all fortunate in that most of us take this very seriously. In all of the people I have met and homebuilt’s I have since starting my first build in 1998 there are only two planes I would not have flown in as a passenger or pilot. But I digress.
I do my best to build safely. When I run across issues I am not certain on I will take advice from fellow builders and if it is a safety related issue I will run it by a licensed A&P. If I do not get concurrence I will ask what I need to do to correct the issue. I have not found ZAC to be a great resource in that they will only answer questions directly relating to the product. If you have tweaked anything you will be very lucky to get anything other than a vague reply. I don’t know about you other guys but I am not willing to bet my life on some of the responses I have gotten from them. And I can’t really blame ZAC for this. They are not in our hangars to see some of the crazy shit we have all done.
Regardless…I wish I could figure out a way to make money doing this because I love building these projects so much. I wish I could be in the hangar right now instead of my office.
I hope you all have a great Thanksgiving and please build and fly safe.

Hi Guys,
This goes to show how tricky this can get.
Summer 2011 I flew to Osh Kosh with a friend and we got stuck in his
RV-6 with an IO-360. WE tried hand propping and were told by the A&P on
the field you could not hand prop a fuel injected engine! Whether or
not that is true I really don't know. But I do know we could not get
that engine to start by propping it to save our lives.
When we installed the new starter from ACS she fired right up on first
try.
So go figure!
Steve
