As a general rule, it's better to be a little overbalanced than
underbalanced, if you're worried about flutter. I balanced all my surfaces on my
Lancair
both before and after painting. One possible solution would be to cut the
weight a little big (heavy) then drill a hole in it until you're balanced.
Then after painting you could pour molten lead in the hole to bring the weight
up to the new balance.

The RV10 is NOT the same as 'other' RV's when it comes to 'balancing'
the elevators. After installation of the 'plans' counterweights the
trailing edge will remain 'heavy' when hung by the rod end bearings by
design. It would take ~another 1lb ingot of lead on each elevator horn
to 'balance' as you did with your 'other' RV's. Again....not the case on
the 10.....savvy?

Define ".a bit too much off."? Is it a significant percentage say
more than 10% of the weight? If so you probably should order some new

I wouldn't loose a ton of sleep over it either. You are going to
balance the control surfaces before flying right? If you don't have to
add weight to get them balanced then consider your screw up really a fix
but If you do need to add weight then its time to order some new lead.
Van's is 20min by car from my house though so I usually don't consider
the time involved to get new ones (just the time off work since the
place is usually a ghost town at 4:30pm).
I have not installed or balanced my elevators on the 10 yet but I have
on a RV9A and a RV4. In both cases the weights that we started with
were too heavy and needed some significant trimming to be considered
balanced. Everyone's planes will be different as some builders proseal
the trailing edges and others don't. How about the weight differences
in the trim cable anchor brackets from van's vs. some of the aftermarket
ones? My point being Van's can't supply you with the exact
counterweight 100% of the time.
The 4 & the 9 that I fly have balanced control surfaces and do not
"droop" as one person said. Despite my repeated efforts neither of them

How many C-172's do you see on a ramp with the elevators drooping? The
elevators themselves are balanced about the hinge-line, but the
control linkage weights basically "pull down" the elevator. This is
also one reason there's an aerodynamic balance tab on a C-172
elevator.

Hmm, production(certified) aircraft have a specification for how many
grams wt. you should measure at the trailing edge when the bearings
are suspended on a knife edge. It would seem prudent for Vans to have
such a spec for the -10 if in fact they should not be balanced with
zero wt at the trailing edge.

If you over cut, don't waste your money on ordering a new weight. Nail
up some scrap wood to the same shape as the original, melt the lead, and
pour a new one. Much cheaper than the shipping charge on a buck worth
of lead.

The 172's I've flown(pre 1977) had nothing of the sort. The elevator
would fall to the rear of its own weight. The only tab on the elevator
is the trim tab. But its a little different when Vne is 150 mph.
Mooneys on the other hand, have Vne's of 189mph MIAS and up(most newer
models well over 200kts), and they definitely are balanced with the
elevator tail heavy, with a weight spec specific to the model, while
some models have bungee springs that change the resting point of the
elevator depending on the trim position, because the entire tail
pivots, changing the angle of incidence of the horizontal stab.

Rick -
It remains an intermittent occurrence on this list, that builders will try to persuade
other new builders to cut a safety corner "here or there" because they
haven't had the problem yet. There is(are) a clear reason(s) why control surfaces
require a certificated A & P to balance them after painting and log the
compliance. I would hope all readers either understand the reasons or research
it for their own enlightenment.
Last week, a surviving spouse using an ambulance chasing barrister (Please no offense
intended Russ), prevailed in a $10.5 million dollar settlement against
the third largest EAA fly-in in the country. Arlington, WA has always been a
great retreat around the 4th of July each year - until now. The circumstance
was a pilot of an RV-6A failed to complete a landing on the airport and was cremated
when all the little extinguishers by the EAAers ran out. The wife and
her barrister will be splitting $8.5 million which is to be paid 50% by all EAA
members and the specific chapter in Washington. The attorney for the fire department
got their responsibility for not responding faster (6 minutes) to be
dropped (hence the $2 million that will not be paid by the City or the Fire Department).
Their patience since 1999 and your membership dues have made at least
two people happy.
When you consider not balancing your control surface, think about those other builders
who will cover the cost (after the fact) and choose wisely. As a timeline
reference, the correction of the improper cut can be done "After Paint but
before Flight" and we will all rest better. I would be pleased to get the replacement
part for you (as I live only 7 minutes away and ship it no cost by
FEDEX whenever you choose).

After installation ofthe 'plans' counterweights the trailing edge will remain
'heavy' when hung by the rod end bearings by design. It would take ~another
1lb ingot of lead on each elevator hornto 'balance' as you did with your 'other'
RV's. Again....not the case on the 10.....savvy?
It's not spelled out in the plans....this info fromVans via land line.

Properly mass balanced control surfaces are important for reducing the effects
of pilot induced oscillation (PIO) and flutter. This is one place where I would
be especiallycareful to follow Van's plans precisely, as they have done the
math and engineering on this for us.

I haven't weighed it.

Hmm, production(certified) aircraft have a specification for how many
grams wt. you should measure at the trailing edge when the bearings
are suspended on a knife edge. It would seem prudent for Vans to have
such a spec for the -10 if in fact they should not be balanced with
zero wt at the trailing edge.

cut a tab of baffling material and drill a hole in it to fit rivet. Push
tab on back of rivet and hit lightly to set rivet. Then remove tab and
finish rivet. I posted pictures of this in the past.

Following Michael's dry sense of humor, rather than be exposed to the

If you over cut, don't waste your money on ordering a new weight. Nail
up some scrap wood to the same shape as the original, melt the lead, and
pour a new one. Much cheaper than the shipping charge on a buck worth

Hi Shawn,
Use a small piece of leather with a hole in it(I've also used dense
foam). The hole fits over the shop side of the undriven rivet. Then
press down on the leather with your bucking bar until it contacts the
undriven rivet end (it should push the tab flat against the underlying
aluminum.) Start to set the rivet with your rivet gun until the rivet
holds the tab in place. Remove the leather and finish driving the rivet.

Hi Shawn,
If you can get to the shop head with a back riveting tool, the tool
will hold down the tab. If not, you can make a notched or stepped
bucking that will hold down the tab with one surface and buck the
rivet with the other.

You can back rivet it, and the spring loaded collar will hold it down,
or what I have down is use a plastic tweaker (electrical term) to hold
the tab for the first one or two strikes by the gun, this causes the
rivet to swell enough to hold then you can take out the weaker.
Depending on the angle it can be difficult to hold the bucking bar and
tweaker with both hands, but get used to it, because there will be many
more times you need 3 hands to do something

You could try to back rivet it. The collar on the back rivet set should
hold the tab in place. You'll need a back rivet bucking bar and an
assistant. Future reference: don't punch out rivets that are
associated with tabs or thin flanges, drill them out. You'll avoid this
problem.

Thanks all for the responses. Didn't mean to get another war going. A lot
of good advice for everyone. I think I like John's response the best and
will just cut down the trailing edge. Just kidding! Hey, it would save on
overall weight as well. In the end I'll be putting the correct weights on
and tweak it when I get to the final rigging.

maybe I'll be the last to post and I think I read everyones responses. An
important point to consider is that once the elevator tip farings are
installed, one can no longer get access to the bold head or the nut of the
bolt which holds these weights on. So it might be wise to error on the heavy
side so that one could nip away at the excess weight in the future if the
lead needs to be lightened.
I suppose one could also epoxy in the nut to the rib so that one could
replace the weight and still torque it down without removing the faring and
messing up the paint job.
I don't think anyone mentioned this.

John,
Thank you for filling in some of the specific details. Your post is the first
giving a location in the Vans manual where the balancing is detailed.
Now I wish they would give instructions on how to check your rudder or elevator,
not just giving the values.
Does someone have the instructions detailed on their web site or do we have to
go to Vans individually to get the instructions?

Gary,
Actually the equipment needed for checking the counterbalances is quite
simple. For the elevators you need a rod attached to the elevators
extending forward to a point 37.5 inches from the hinge centerline with a 1
lb weight attached at that point. ( 37.5 in/lb ). This is with both
elevators attached, the trim in place and the tips on. If your choose to
pop rivet the tips on you should probably wait until the final balance is
done. ( Didn't tell us that in the plans did they? I used #4 screws and
nutplates for mine. ) Adjust counterweights so the elevators rest trailing
edge low. Any other builders who want to correct or expand on the above
procedure please do so. I'd appreciate constructive advise particularly
from previous RVers. BTW. The old -6 plans called for the builder to melt
lead ingots into a mould to form the counterweights. Boy are we spoiled!!

Looks like Van's has issued another service bulletin, this time aimed at
us "Hot Rodders"
http://vansaircraft.com/pdf/10_motor_mount.pdf
Scott was extremely helpful and modified my mount. Looks like they won't
be doing any more!

This is only hearsay, but Van's has changed a lot of the ways they do things
since the -6. Enjoy, though. You will only appreciate the plans and
prepunched holes on the -10 that much more after working on the -6.
Do not archive.

Thanks. Looks like I am going to first start helping an A&P friend
finish an RV-6 that he bought from an estate. Its in the fuselage stage.
Should be good intro to how Vans does stuff.

Can you back rivet the tab? I would research this first, but could you
use a drop of super glue to hold the tab? I don't know if Cyan glue
will affect aluminum, so check this first.

Subject: RV10-List: Bent Tab
All,
I had to pull out a rivet in my tailcone and in the process of so
doing I bent a tab on the F-1011 bulkhead. Does anybody have a good way
to hold that tab down while re-inserting the rivet? I was able to get
it lined up again but it still wants to stick up unless held down by a
cleko. Removing the part is not going to be an option. Any suggestions
would be appreciated.
