I have 375+ hours on my IO-540 with dual slick mags and have done lots
of hot starts with no issues. Like it has been said before, technique is everything.
Throttle 1/8" to 1/4", Mixture at Idle Cutoff, no boost pump. Crank
and when it fires, get the mixture in right away and turn on the boost pump for
a few seconds. Once I did 10+ hot starts in a row while doing a prop balance,
no issues.
Thank You
Ray Doerr
N519RV (40250)
Hopefully it will be out of the paint shop this Friday.

Subject: Re: RV10-List:
But, specifically the RV-10 IO-540.....
In 330+ hours, I haven't yet had a problem with hot starts. I've flown
on hot days, and had to restart, but just by using the normal hot start
procedure I've always had good luck. Now, my comments are limited
to the IO-540, in an RV-10 installation, using a precision fuel
injection system. If someone wants to use the AFP fuel injection
system....great....but, you may then have a good case for needing
a purge valve...I don't know. They are 2 different systems.
Also, I have a lightspeed ignition, which has been a common install
on IO-540's. So, perhaps someone with just dual mags may have
a small variation in results as well.
In short, all of those things affect how it may work for you, so
you need to be very specific about the exact situation that the
experiences you have come from. There may be combinations that
work perfectly without, and there may be combinations that
definitely require it to be workable for hot starts. I know
I'm very happy with the setup I'm using....for what that's worth.

Is everyone using the bottom cowling vents? This might aid in air
circulation on the ground leading to somewhat better cooling? I have no
idea what I'm talking about, but might be another data point.

Subject: | Re: Spins in a -10? |
Jim,
Thank you for reporting your results. The fact that the airplane has
been spun and recovered (with or without a spin chute) satisfies my
curiosity. Perhaps I was looking in the wrong places, but I was really
surprised at the lack of information about the airplane's spin
characteristics. Rest assured - I, for one, am not about to interpret
your message as a license to go spin. As I noted earlier on, spins are
not something I am interested in doing. I simply saw a gap in the
"knowledge base" and began to wonder if anyone had explored the
behavior/characteristics.
Thanks again!

Subject: Re: RV10-List: Spins in a -10?
I'm a bit reluctant to post this, but I think it may be a useful data
point for the group.
During my fly-off phase I tested the spin characteristics of my RV-10.
I will mention that I was wearing a chute, and I've had spin training in
both the T-3A Firefly and T-37. Also, a little CYA, I am not
recommending this as something to go out and try.
I tested it at a gross weight of 2195# with CG at 110.33" aft of
datum. I tested it in both left and right spins entered from a power-off
stall. With pro-spin controls (you really need to be ham-fisting it to
get it to enter), the aircraft was quick to enter a spin. Once the
controls are neutralized, the spin immediately stopped, requiring a
recovery from the subsequent nose low attitude. While the stall
characteristics of the RV-10 are quite docile in my opinion, the spin
happens fairly quickly. The biggest issue I found was the short time
from stall to extreme nose low attitudes in the initial development of
the spin; the RV-10 is quick to gain speed in this attitude and the
possibility of an overspeed and/or an over-G is large during the
recovery. I believe a spin in IFR would be quickly disorienting. My
overall assessment is that while you can make the aircraft spin, you
either have to want to do it or are really screwing things up to make it
happen. If it does happen, it appears that neutralizing the controls
stops it.
I'll add another disclaimer that this assessment was in MY airplane,
at ONE particular weight and ONE particular CG location with ONE
particular type of entry. It was not at all a comprehensive spin test,
but, it gives me some further understanding of the flight
characteristics of my plane.

Hi All,
I read and watch this list with interest and envy. I am not a
builder (yet), but I do have a plan in motion and intend to building an
RV-10 in the summer or fall of 2009. I thank you all for the informative
thoughts and ideas I have had the pleasure of observing!!! My "to-do,"
"wish," and "check this/that/the other thing" lists are getting quite
lengthy. :-)
In all of my reading and research, I have not been able to determine
if:
a.) the RV-10 is safely spinnable
b.) anyone has compiled details of its spin characteristics
(providing the answer to a. is yes)
I know the -10, along with the -9(A) are not intended or designed
for aerobatics, but this does not address the spin question to my
satisfaction. For example, Cessna 1[578]2 aircraft are not built for
aerobatics (15[02] Aerobat being the exception), but they are certified
to spin.
The ability / inability to spin has absolutely no bearing on my
decision to build a -10; in fact, I am asking out of little more than
morbid curiosity.
Thank you in advance for any additional info and/or thoughts on the
subject.

I'm not a big fan of alternative engines, but the LS1 (combined

I'm still not sure if I'll put the LS1 in there or not, but I do

Bud and I are members of the same EAA chapter (302). He's a great

I picked a -10 for the same reason. A few years ago my son-in-law
blurted out that he'd like to build an RV-7.
Why, I asked.
Because it looks neat, is predrilled .... and all the other neat things.
But it's a 2 place airplane!!! I said
"I know." was his reply.
It may come as a big shock to you, but you're about to be a 3-place
family! I said.
"Good point." was his reply.
How about an RV-10 .... all the same reasons you had for the -7 and
it's a 4-place. I was protecting my seat, you know!
So time goes on, and Owen blessed us with his appearance. All is good.
But then, along came his sister Sarah!!! THERE GOES MY SEAT!!! :-(
But then neither of those two grandbabies seem to be totally impressed
with airplanes ..... so this may turn out all right after all!!!

ECI has been quiet about IO-540 plans. For those looking for options, there is UQM technologies and their powerphase 150 motor. http://www.uqm.com/products/specsheet.html. Downside is continuous power restrictions would get you only ~ 110 HP and current state of the art battery (LiON, including M3, etc) would keep you in the air for ~ 10-20 mins. Then it would be really quiet! :)

But, specifically the RV-10 IO-540.....
In 330+ hours, I haven't yet had a problem with hot starts. I've flown on
hot days, and had to restart, but just by using the normal hot start
procedure I've always had good luck. Now, my comments are limited to the
IO-540, in an RV-10 installation, using a precision fuel injection system.
If someone wants to use the AFP fuel injection system....great....but, you
may then have a good case for needing a purge valve...I don't know. They
are 2 different systems.
Also, I have a lightspeed ignition, which has been a common install on
IO-540's. So, perhaps someone with just dual mags may have a small
variation in results as well.
In short, all of those things affect how it may work for you, so you need to
be very specific about the exact situation that the experiences you have
come from. There may be combinations that work perfectly without, and there
may be combinations that definitely require it to be workable for hot
starts. I know I'm very happy with the setup I'm using....for what that's
worth.

This is off topic, but my wife just gave birth to Gracelyn Wato Saint this
morning at 5:00. Nothing against airplanes, but this is a little more
exciting than giving birth to an airplane, which many of us have done and
many are yet to do.

What flap extension speeds are being used? I see the full flap extension
maximum speed is 85 kts. I have flown the 10 like my old C177RG. Approach
flaps at 120 kts to begin slowing and further deployment at speeds below 90
kts indicated. Seems to work as an approach flap of 10 degrees begins the
slowing process and no excessive forces seem to be experienced. What are
others doing?

Subject: | Re: Spins in a -10? |
For a brief period I instructed spins in the Navy. Quite frankly, it's like practicing
to bleed. Stall recovery training and avoidance of icing is what you need
to know.
If you are morbidly curious about what would happen, have you thought about spins
in a 747?

Subject: | What is Vans working on now? |
With all the talk of more babies (congratulations Jesse & co), and now
that the RV12 is completed, can anyone tell us what Vans design team
is working on now?
Will the RV14 be a high speed, 2 seat jet, or will it be an extended,
6 seat IO550 RV10+2 = RV14?, or even better from my point of view, a
VTOL 6 seat jet??
Or how about underwing baby pods for the RV10???
