Are there any builders out there who have fitted the Airflow Performance pur
ge valve to their RV-10, who could please indicate:
1. the approximate length of the cable used;
2. the supplier of the cable; and
3. if they used a cable with some form of locking mechanism on the cable to
prevent actuation of the purge valve in flight, such as the A-750 VERNIER C
ONTROL cable sold by Aircraft Spruce: http://www.aircraftspruce.com/catalog/

Please let me know if this is suitable?

Hi Patrick,
Yes, I have the purge valve. Not flying yet.... about 4 weeks away,
however, check out my web site and give me a call or drop me an email to
discuss.

I'm using just a regular cable like you can buy from an auto parts store. I
will eventually change it out to a locking type cable. Vernier is really n
ot necessary but locking is because the vibrations cause the cable to pull
out and eventually shut down the engine if you don't keep pushing the knob
in.

1. Depends, too many variables for a standard length cable. For example, w
here are you mounting the control, where does it penetrate the firewall. I
have an Aerosport Products panel and have mine mounted on the lower console
by my right knee. Then it goes through the firewall in the recess area wit
h all the throttle quadrant controls, then penetrates the baffle between the
oil cooler scant tube and the center of the engine block. Then it crosses t
he engine block to the purge valve. I suspect no two installations are the
same. You may have to adjust clocking depending on your exact route of th
e cable. I used weed whacker line to determine the length that I needed.
2/3. I used this McFarlene control cable. I wanted a locking control. Y
ou don't want the cable moving in flight. (http://www.aircraftspruce.com/ca
talog/appages/controlsMC6150a.php). I ordered the cable directly from McFarl
ene. It was about the same price price as ACS, but they will do custom eng
raving.

I did the same on the 8A. The purge valve itself has a spring but I added
another to make sure. Photo attached. As someone else has pointed out you
can easily get by without a purge valve. In 11 years I used this perhaps
half a dozen times for hot day, hot start situation. It does work. The
return is plumbed to the left tank so when purging you select the left tank
for fuel. The purge valve is also used for each engine shutdown. This
ports the pressurized fuel in the spider to the tank to reduce the amount
left to gravity drain.
Standard cables like these work well:

Or: http://vansaircraft.com/cgi-bin/store.cgi?ident=1399824452-324-42
<http://vansaircraft.com/cgi-bin/store.cgi?ident=1399824452-324-42&browse=co
ntrols&product=bowden> &browse=controls&product=bowden
On the photo note that this was the first two years or so of flying - before
the multiple hard LightSpeed ignition failures. The LightSpeeds are long
gone and the plane is doing just fine at 400 hours on dual p-Mags. I'm
still holding my breath (like many) for Brad to ship the 6 cylinder p-Mags
for the RV-10.

I started out with the same setup that Carl shows in his photo i.e. simple wire
push-pull cable and B nut, plus return spring. In talking with Don Rivera at
Airflow Performance, he made it clear he was not a fan of that arrangement, since
failure has the potential to shut down the engine. He prefers a more robust
push-pull cable with threaded ends and a clevis fitting in place of the B nut.

If it is anything like the IO-360 Lycoming I have in my Mooney, the
trick is to bring engine to 1000 rpm for shutdown and pull mixture.
Then, for startup, don't touch anything, do not use boost pump. Just
crank. If it doesn't fire within about 6 revolutions, begin to slowly
ease the mixture in and it will fire somewhere around 50% mixture. Don't
crank beyond 10 seconds. If it doesn't fire, stop cranking. Reasses. Add
a hair to throttle and try again with mixture at cutoff through 5-6
revolutions then begin adding mixture.
Last resort, prime it like cold start to flood it, go full throttle,
lock brakes and mixture idel cutoff. Crank til fires and immediately
reduce throttle while adding mixture.

I was taught the same procedure Kelly describes and it has worked flawlessly on
my IO-540 RV-10. A friend of mine also does the same with his IO-360 Cozy MKIV
and has almost 400 hours doing hot starts this way When I did my RV-10 transition
training in TX with Alex, he did hot starts using boost pump to flood engine,
full throttle and idle mixture cut-off, rapidly pulling throttle and pushing
in mixture when engine fires. I don't care for that method. Only 23 hours
so far but plenty of hot starts for me and she always fires up very smoothly
by the third blade. So far I have not even considered installing a purge valve.
It adds expense, time to install, weight, and complexity.

| Subject: | Airflow Performance Purge Valve Fitted to RV-10 |
Don - The basic problem with hot starts is the vaporization of fuel in the
lines to and from the spider or distribution block. I have not had experie
nce with the IO-540 but the same problem existed in the IO-470's of which I
had two in a Cessna 310. In that case it was mixture at idle cut off thro
ttle at mid-point and hit the primer (the boost pump with a momentary switc
h) for about 10 seconds. The fuel would circulate and eliminate the vapor.
With the mixture at ICO and the throttle cracked hit the starter and when
it fired mixture rich. Having one hand on the starter and the other on the
mixture was a good idea.
But the basic problem is the vaporization of fuel in the lines due to the h
eat of the engine. A method to do that without flooding the engine and you
r good to go. If it makes you feel any better it is not an uncommon proble
m with all fuel injected engines but it's more prevalent in the bigger one
(6 cylinder).

I'm using just a regular cable like you can buy from an auto parts store. I
will eventually change it out to a locking type cable. Vernier is really n
ot necessary but locking is because the vibrations cause the cable to pull
out and eventually shut down the engine if you don't keep pushing the knob

Jim, there are quite a few different techniques, but here's what works for
me.- Cold start;- crack throttle, mixture 1/2, hit boost pump for about
3 seconds, then start.... since I have a light MT prop and an engine with
higher compression, and the ability to leave ignition off when I start cran
king the engine....then after a couple of turns, I turn on the ignition...
totally eliminates any kickback or backfire. =0A=0A=0AHot start;- very si
miliar, except after hitting the boost pump for it's 3 seconds, I pull the
mixture back to cuttoff, then hit the starter.... when it catches, ease the
mixture back to 1/2.=0A=0AIf you find that it catches and then dies, try u
sing the boost pump slightly longer.=0A=0ADon=0ALet me know how it works.

Be aware that Continental fuel injection is COMPLETELY different than
Bendix or AFM fuel injection, and technique used with it is completely
different. Continental injection has a continuous return line, which allows
purging every line up to the fuel servo by recirculating fuel from the
tank. It also requires management of which tank fuel is burned from to make
room for the return fuel.
The flooded start method I described I consider a last resort, and should
not be used routinely. 1st, having the engine fire up to near full power
has safety concerns and is hard on the prop and the engine. 2nd, excess
fuel in the cylinder washes oil of the cylinder wall, accelerating wear.
