Steve,
Unfortunately, I have a fixed rudder tab set for my cruise speed of 165 knots/180
mph indicated. Faster or slower requires some of that "pilot stuff" with your
feet which I like anyway. However, I saw an RV6 at a fly-in with a movable
tab rigged with a cable similar to the elevator trim on the 4. You could design
one easily, I would put it on the lower portion of the rudder. Cheers!

Rob - how have you implemented a rudder trim. As a fixed or adjustable tab.
Also, anyone know if VANS have ever implemented an offset rudder on the -4
like on the _7 and -9?
Rear seat heat. have you fixed the problem. I was thinking of solving it
with an electric seat heater but have no idea of the current draw.
thanks, Steve.

I purchased some "V" strip to use as a weather seal on my RV-4 tip up
canopy. (ACS #05-01900) I know that on the front I need to keep air out therefore
the incoming air would open the V and do its sealing job if I point the seal
inward . However, I'm not sure if I need to do the same on the rest of the
canopy. Which way should I point the seal? Is the balance of the air incoming
or
is it going out? I think the balance of the air would be outgoing,
especially if I had the heat on. That should pressurize the interior so I'm assuming
that the sides and rear of the canopy should have the "V" pointing out. What
have others done? Thanks in advance.

I have used the plastic brake lines for 1200 hrs. over a 13 year period. I
replaced them at 750 hrs. because they seemed hardened and it was so
inexpensive. I have never had a problem with failure from overheating
although I have never had to make a panic stop. For me the biggest problem
has been keeping them from leaking at the joint on the wheel cylinders. They
occasionally (too often)begin to weep and if not tightened will leak away
all the fluid on that side resulting in no brakes just when you are in a
hurry to leave on a trip (or so it seems). Frankly, I'm tired of them and am
looking to replace them with something else the next time I get let down.
So, yes they work, but be vigilant if you use them.

puzzling 'cos this is done in aluminium in later VANS designs. Is there a
reason why plastic on the -4?
