Hi all!!!

I have spent 5.5 years putting together a collection of parts and a couple

of months putting together a stack of paper. Today I met with a DAR and
about 4 hours later I have a pink airworthiness certificate and an
official
airplane.

My Dragonfly/Corvair N187CD became an airplane today!!! I will proceed to
do the first flight when everything is given a final checkout and the
weather is just right. The rest of the 40 hours of testing and data
gathering
will follow as weather permits.

Count me as one of the soon to be one hundred flying Corvairs.

Keep Building,

Charlie Johnson
Owner of a new Dragon/vair

Subject: Engine update - N240JS



























William,
 
Below is an update I have drafted for The Q-list.  I have two questions:  (1)Did you change the distributor setting shortly after engine start?  If so, did you increase or decrease the advance?  (2)  Is the Warp drive prop at the same setting as those engines used to establish the "Direct Drive Corvair Engine Spec Sheet" published on your web site? And, what is that setting, e.g. 9 deg.?
 
Joseph
 
 
Hello Q-listers,
 
On July 22, 2011 N240JS suffered substantial damage during its first flight. For details see attached NTSB report attached.
 
I removed the engine from the Q2xx airframe exactly as it remained after the accident, e.g. crankshaft position, distributor setting, wires, oil, etc.
 
I transported the engine to Corvair College #21 at Barnwell, SC.  It was placed on the engine test stand.  A Warp Drive test prop was installed with a pitch setting standard for Corvair 2700cc engines.
 
The engine was started by William Wynn and allowed to warm up.  Mr. Wynn checked the distributor setting.  The engine was advanced to WOT.  A digital optical tachometer recorded the static rpm at 3160.  William Wynn's testing indicates that a Corvair engine develops 100 hp at 3150 rpm and 160 ft/lbs torque at 2800 rpm ,  http://www.flycorvair.com/corvair.html  
 
After the test run, Mr. Wynn rotated the prop by hand and reported the engine rotated smoothly and compression between the cylinders seemed even.  The engine was disassembled  There was no metal observed in the oil pan.  There was no visual damage to the cam gear, the crankshaft or the main bearing shells.  The aluminum cam gear will be replaced.  The crankshaft main journals were tested for runout using a dial indicator.  The runout was less than 1 thousanth.  The crankshaft will be magnafluxed.
 
The result of this test seems to confirm that the Sterba 54X57 prop prevented my Corvair engine from spinning up to its horsepower potential during the first flight of my Q2xx and prevented the aircraft from accelerating to its recommended 100 mph climbout speed.  Mr. Wynn is recommending a Sensenich 54/54 wood propeller for the Q2/Corvair (2700 cc) combination.
 
For photos of the test, follow this link:  http://www.flycorvair.com/hangar.html, photo # 12 & 22.

Q2xx, N240JS
 
William Wynn's reply:
 

Joseph,
 
I altered the timing just slightly on your engine after the the first run at power, the change was only +2 degrees,
this doesn't make much difference on a Corvair at that setting. Because of the cylinder head design the Corvair
makes its maximum power at 34-36 degrees of advance, which it can only run on 100 LL for. However, we use
30-32 degrees because extensive dyno tests have shown that the power reduction is only 2-3%, while giving
the engine a very wide margin against detonation. Your engine was set about 31 degrees, I bumped it to 33 or so,
no change in rpm was noted.
 
The prop we use on the run stand is a 62" Warp drive with a pitch setting that static's at 3100rpm on a 2700cc
engine, or about 3250 on a 3,000cc Corvair.  This setting allows us to check that the engine makes it full rated power
in comparison to other engines. A typical Zenith 601XL flying a Warp Drive prop uses a 66" prop set at 9.5 degrees.
this produces a static rpm of 2750 to 2800, which will peak out at 3200rpm  at WOT in level flight. Produces the best
combination of cruise and climb in that airframe. 2700cc Corvairs in faster airframes use props like 54x54 sensenichs
which will static over 2950, which is well into the corvairs power, combined with a blade angle that gives very efficient pull
from brake release. Even though 54" does not sound like much pitch, a KR-2s with this pitch on a Corvair has exceeded
180mph in level flight at sea level. The rpm was over 3700, but this does not bother the engine, It turned 3500 rpm at 70mph
in the car. My conclusion is the same as yours, that the engine had a mis-matched prop on it for your application. The Q's
thrust requirements were not met because the combination of the engine being too low in the powerband and the high pitch
setting of the prop having much of it's blade area stalled. A lower performance airframe with lower wing and span loading
would have tolerated this, for example, we have had 270 pilot unknowingly TO in a 601 on 5 cylinders...4 times. Only on
his 5th flight did he discover the missing plug wire. The Q-2 isn't this forgiving, and I think your issue could
have been avoided with a better prop match.


 

Thank you.

Some of my first flights on a plane that hadn't flown in a while. See http://cuesmile.wordpress.com/

Comments welcome! I'll try to update that site regularly, so if I forget, you're welcome to remind me.

Many thanks to Bruce for his help.

I do not have any pic's but I will try and get some tomorrow. Basically it
is a a box without the bottom made out of fiberglass. Light weight , holds
it shape and works good. All I did was to cut the corners off of the front
and made a fiberglass peice that goes down at an angle to allow the cowl top
to fit. If it all works good I will be very happy

Darrell,
I am rebuilding my baffling for my Revmaster and am stuck as to where to
proceed next. Could you post some close ups of your baffling if you have
any pics available?
Thanks!

Subject: [Q-LIST] Two steps forward one back

Well I went to put the cowl on my airplane and discovered I had a few
problems First the smiley on my cowl did not line up with the baffeling
work to cool the heads , Second I went to put the top on and the duct work
for the baffel was to high in the front. Now cutting this down was simple
enough but the fact is that Paus Spackman had done such a beautiful job of
making it I really hated to cut it down. It does however turn out that by
Pauls example he turned out to be a very good instructor. Now that I have
re done the top baffeling I will tomorrow start changing the bottom part
of the cowel . I also fixed lobe that was busted for one of the tubes in
back , I was concerned that the epoxy took a long time to cure. I mixed it
by weight on a scale , could have been the temp was not as warm as it
should have been.
Also I cannot wait to fly this because I already get Wat kind of a plane
is that. and How many of them are there. Darrell
