Screech,
I did a similar thing to what Greg mentions below. I used doubler strips to stregthen
the HS forward spar. I think I used several 0.040 or 0.032" strips as
opposed to angles. I used the strips because the angles must have one leg trimmed
off to fit under the skin. Anyway, same idea that Greg had, just a slightly
different approach. The strips were 1 1/4" wide and I reinforced the bottom
of the front HS spar as well as the top.
I also added the VS forward spar doubler just like Greg did.
Don't get too carried away with adding metal though. Those AN3 bolts (3/16") that
hold the forward HS to the longerons can't be made any bigger unless you do
some serious (and unnecessary) redesign work.
And remember to CAREFULLY plan how this all must fit together or you'll make it
impossible to fit the VS to the HS to the fuselage longerons!!! Doh!

Subject: Rocket-List: -4 tail mods??

Well, I'm back from shooting at the indians and the USMC was kind enough to
send me up to Reno to be a TOPGUN Instructor....bummmer! All moved into my
new hanger at Stead field and pushing ahead full steam (again) on building
my F-1(#20). Almost have enough parts to put together an airplane.
Question: I have completed an RV-4 tail to John's plans (still have to move
bottom rib of VS..ooops) but am interested in beefing up the HS spar.
Anyone done this? Seems to me that the Fwd spar is a little thin and could
do with a douber in the middle and/or a couple of angles at the inboard
ribs. I know there are some smart guys out there with ideas, just remember
to make them "Marine-proof". Thanks in advance.

The RV-4 horizontal is indeed in need of some beefing up. The forward spar
is week at the top in compression, a loading situation that is not normally
encountered, but with enough speed and some negative G, like in turbulence,
it is possible. The failure mode is buckling. To fix this add a standard
extruded angle to the top of the spar, spanning the forward spar from rib to
rib. Once the spar is inside the ribs, and under the skin there is no
problem with buckling. You can pick up the rivet pattern of the planned
rivets. The only other area I beefed up was the forward spar of the
vertical, doubling it with a piece of .032 and extending up a couple inches
into the skin area, this was primarily for extra sheer resistance against
the attach bolts.

Hi gang,
I am at the stage where one tries to figure out where to position all
the components of each system and where to run the various cables, fuel
and oil lines.
I'm looking for pics of Rocket firewall penetration points in particular
for throttle cables, fuel line, main electrical line, hot and cold
ventilation hoses and brake lines.
I'm also interested in where guys are locating the inverted oil valve.
I've viewed all the pics on Vince Frazier's site and gained a feel for
it but I would like to see more to avoid boxing myself in.
Tom Martin, I think with your experience, you probably know the best way
to plum a Rocket, can you help?
Thanks,
Jim Stone

Do Not Archive Does anyone have sidewall upholstery templates/patterns that
they would not mind sharing? Also patterns for making carpet cutouts? I have
a Harmon Rocket II, and would very much appreciate your previous efforts. Any
info on rear seat armrests would be helpful as well. Thank you very much,
Les Featherston N206KT's and flying past 50 hrs. Do not archive!

Do not archive! Anybody out there have a positive or negative comment on the
storage compartment behind the passengers head in the turtle deck? Can you
provide design help or drawings to assist in the construction? Is it worth the
effort? Thank you very much, Les Featherston N206KT Flying and could not be
happier with the airplane. Lovinit!
