REFLECTOR: Aerobatics: Non center line rudder

Sun Feb 20 12:31:40 CST 2005

Alex,

Thanks for the advice.  Actually the RV8 was a contender, but you freeze
out your backseater (in my case wife) on the cross country
flights...which is my principal use.  I don't think the RV10 is stressed
for aerobatics.  My only experience with acro is in a T-38 in 1968 doing
about 300 kts.  So it's been a while, and add to that I have limited
time in SEL recips.  Sorry for sounding so stupid.  I am just trying to
get an understanding of accelerate/decelerate capabilities and more on
the flight characteristics of a carnard.  I am getting the XL so those
rudders are way out there and don't work in tandem.  Thanks for your
input.  I get your point about sustained level inverted flight is
different with a cannard design.  

I still don't think of an aileron roll maneuver as ever going negative.
It you start w/ the nose up +10 from level I can't invision losing
altitude either.  About the cuban eight...but I would want to execute
constant-heading half rolls without the airplane fishtailing due to any
possibly needed non-centerline rudder inputs to compenstate for torque
influences w/ larger throttle changes.  Is this an issue?  Have you got
a comment there?  As a small aside, my Saturday acro occasionss would
not include any intentional neg g's!  Yuk.   Thanks for the welcome and
for getting back when you have a minute.  
Terry

Hey Terry,
Welcome to the reflector!
About the velocity doing aerobatics, the canard design in general, and
the Velocity in particular does not lend itself well to any negative G
maneuvers due to the load being shared by both the wing and the canard,
in most other planforms, the wing does all of the carrying, so if you
want to go inverted, you just need to fly the wing at a positive angle
of attack with the ground. If you try a roll with the velocity, you
might pull it off, some have, but chances are, as soon as you go
inverted, you will find that there  isn't enough down elevator to keep
the nose level, and the canard is going to pull you really hard toward
the center of the earth, and you will end up doing an un-commanded
split-s.  If you like doing Aerobatics, even Saturday morning style, you
would be better off in an RV which is a blast to fly that way.

Hi,

I should enjoy my ignoble status while it lasts. I have the honor to

be the very newest running nose, wide-eyed kid on the block. The kit

gets delivered in a month or so.   In fact I can't seem to get my own
email out (reflector at tbvf.org) so I had to use the reply function to get
this on the Reflector.  Sorry Dave.  

I've got a quick kind survey question on acro. I bought the V kit for xc
reasons, but are any of you out there doing cuban eights? Is the
airplane any good as an acro platform? I know it can take the G
loading...but what about roll rate with rudder deflection not
centerline?   Rudder and aileron size and effectiveness? I didn't
understand a thread in the archives about dishing out of an aileron
roll...did they mean like barrel roll?  If you raise the nose just a
little and bang the stick to the left won't it just roll around a point
w/ very little if any heading change, as opposed to barrel roll where
the flight path simulates a corkscrew as opposed to a spinning top?  

Are there and VNE problems w/ say doing a simple split S and no speed
brake? The only acro I have done is in jets, so I am a little lost on
this stuff.  Has anyone developed any target speeds/power settings for
continuous cuban eights?  Anybody doing in trail formation stuff that I
could talk to off line? 

Thanks for helping with this. When I become more informed myself, I hope
to somehow return the favor down line.

Terry

Now back to your regularly scheduled program....

Check with Steve Murphy.  He gave me my company check ride.  Also has
checked out many others.  He will charge you a small fee for the check
ride and light fees for the training in your plane.  Plus his cost for
fuel to come to your airport.  He live up in the Reno area.  
He had no problem with me seeing I had 1500 hrs in  canards before
flying my Velocity.  I now have 60 hrs on it since last March.  
I'm not a CFI but if you need time in a Velocity before you fly yours
come by and we can make it happen.
