| Subject: | Re: RV-7 engine/prop options (correction) |
Thanks but the Hartzell BA is the FASTEST, faster than the
Whirlwind, Aerocomposite and MT and Sensenich.
Where are you going to get the Whirlwind worked on?
The company has been sold off once already?
What if it goes out of business, get sued?
Prop shops will not work on it, even though the hub is a Mccauley.
The prop has not been tested at all as far as I know, much less
with modified engines (high compression, electronic ignition).
Here is the Van's flight test data:
http://img82.imageshack.us/my.php?image=prop200415me.jpg
(Second one down is the Hartzell Blended Airfoil, the first is the
good old C2YK/F7666. The WW 200RV is the second fastestest
behind the Hartzell BA and a little faster than the old Hartzell.
The Sensenich does good at that one data point 75% cruise.
I disagree with the calculated 207.9 mph corrected speed for
the sensenich; you'd lose a little more than 3 mph by pulling
back RPM from 2730 to 2500 with the throttle, but still the
sensenich, optimized for cruise, is 2nd or 3rd in speed. I will
point out of course takeoff and climb will be less and also
flying in cruise with either at 2730 rpm or with the throttle
partially closed is not as efficient as a constant speed prop
that allows independent control of RPM from throttle, ie
manifold pressure. However for value and bang-O-buck,
the fixed pitched Sensenich is a great deal, and designed
specifically and tested specifically for the RV, like the
hartzell BA prop is.)
There is nothing wrong with Whirlwind its a fine product as is
aerocomposite and MT, but any composite prop from a small
boutique prop maker is going to be more....well risk. You can't
beat the Hartzell or Sensenich for value and performance on the
RV. Both these companies have MADE props ENGINEERED
specifically for the RV. The other companies basically have
generic props they sell, one size fits all. Also having large
companies with combined experience of WELL over 100
years is a good thing.
Cheers

It's in the FILES section on the Yahoogrooup. Seatback bulkhead, by the way,
is 705.

I still have to do this step, and I'm about to paint the interior.
Is this article online somewhere? Or does someone have the dimensions
noted?

I went for a ride in Van's rv7a at SNF. My only other Van's ride prior was
backseat in Mike Stewart's Super-8 (much fun). The rv7a ride was great.
Thank you, Van's, for the offering.
Some impressions:
- On engine start, I felt like the plane shook a bit much. Reminds me of
the recommendation to by Lord's engine mounts instead of the one's in Van's
ff kit. Also makes me want to pay attention to any other detail which will
result in engine smoothness.
- We started takeoff roll from a taxiway that was way closer to the end of
the runway than the beginning. We were off in plenty. Cool!
- Same great stick response as on I experienced on my Super 8 ride. I can't
wait to be flying.
- On landing, the nosewheel shimmied. Makes me glad I'm building the
taildragger.
- It got dang hot in the cockpit by the time we landed. It's spring. It
wasn't that hot outside even for Florida. Definitely going to check out
those canopy shades.
Notes on poking around the plane:
- The wingtips I have don't flare outward as much as the demo model. Wonder
why they changed the tips...
- I thought Van's sent me some extra canopy frames by mistake. You get 6;
you need 4 to build the frame. Dang if the other two aren't used on the tip
up canopy. I messed up a pair thinking nothing of it, so crap now I have to
place an order. There are several parts in the fuse instructions which
ship with the finishing kit and vice versa. Annoying.
- I noticed the rudder stops on the demo model do not match the one's that
the instruction have you build. Interestingly, I had to modify my rudder
stops to poke out more to properly restrict rudder swing, and my mod'd
version looks more like the demo ride. I thought I had done something
wrong, but I trusted the end result. I'll post a pic on my site later of
what I'm talking about.
- The rudder was a one piece unit, not like the 2 piece I built. Wonder why
they changed it.

Only Q I can answer is the last. When they spin tested the -7, it had
'marginal' recovery characteristics using the -8 tail assy/rudder. They
offered the larger -9 (2piece) rudder free for kits already shipped &
started shipping the -9 rudder with future -7 kits.
I share your pain on missing parts. I can't finish the fit of the
structure from instrument panel to firewall because of 1 missing part,
packed with finish kit. Duh...
I also wasted about an hour discovering what you did about the 'extra'
canopy frames, but fortunately I didn't trash them 1st.
Van, here's a thought: pack the fuse parts in the fuse kit & the finish
kit parts in the finish kit.

I'd guess the demo model is the "old" rudder.

Would be good for any serious builder to read through all the applicable
SBs and Letters, specifically this one:
http://www.vansaircraft.com/pdf/sb02-6-1.pdf That addresses the change
in the rudder.

//I share your pain on missing parts. I can't finish the fit of the

That's got to be one of two parts: the "hat", or the long rib going to the
firewall. I learned -- the hard way -- that there's a reason they don't give
you the "hat." You'd be tempted to rivet it on. Bad move since it requires
the installation of nutplatest they don't tell you about and also you need
to make a hole in it, which also isn't on the plans.
I found that whenever the instructions say rivet this or rivet that where
the subpanel is concerned, DON'T.
The whole subpanel section should be in the Finishing kit instructions, not
in the fuselage kit. There's nothing to be gained by installing it at the
point in the instructions it exists in the fuselage instructions.
