The original RV-4 kits were not & are not available in QB,
pre-punched, pre-marked, pre-aligned, pre-anything, no jigs
required....in other words. YOU measure, build, drill, jig, alignment
line, one step up from plans built. Since you have a 6A, think about a
HRII Rocket. Ya take some -4 parts, some parts from John Harmon, invest
in a 540 Lyco as we did and build an HRII for about the same price as a
-4. But you get an RV-4 on steroids. Since the RV-10 the price of 540's
has gone up. When we build the Rocket they were cheaper than a IO-360. I
assume you have ridden in both the -4 & an HRII.....if not do so as soon
as possible. Is the HRII harder to build than a -4 ?..Yes, a little, but
well worth the extra work. Too bad your in Ohio or we would give a ride
in N561FS. I'm going to post on the Rocket list so watch your e-mail,
someone near ya'll may offer you a ride. I assume you built the -6A so
an HRII is just more of the same and "Mo Better". Do Not Archive

List, I am getting the urge to build an RV-4 to set next to my
RV6-A in the hanger. Since I want to build this one as reasonable as
possible orphaned kits are a good option.
I have located a 1989 Tail Kit with very little done
at an excellent price. Question for RV-4 Builders: Are the 1989 kits
less advanced than the newer ones? RV-4 kits appear to have made fewer
advances.......pre drilled skins....QB, etc? Any reason other than
corrosion to stay away from the 1989 tail kit?
Thanks, Tom in Ohio

I understand that several HRII's are flying with the slightly larger
RV-8 tail feathers. I have no personal knowledge on that but I'm sure
there are HRII drivers out there that will respond. KABONG Do Not

Actually a HRII is what I have in mind! Several people on the list
have advised me to go with .020 Skins on the elevators and rudder which
sounds like a good plan.

I have built and flown two HRIIs with RV8 tails. They are easy to build and
the vertical surfaces work quite well. The elevators can be described as
adequate but could benefit from a bit more chord, one inch would do. Having
built and flown rockets with the F1 tail I would say that it is my
preference. The vertical surfaces are not quite as tall as the 8 tail but
the rudder is larger, the elevators are also larger and provide better
control in the flare. Aesthetically, in my opinion, the F1 tail is the most
pleasing of all the options. Many rockets use the RV4 tail but I have not
flown one myself.

I have a HR2 with F1 tail (there a few around in this config). As you
might guess, this works well. My only hesitation, I'm not convinced
about the riveted trailing edge on the elevator.
Many F1 guys complain of high stick force but you don't here that from
the HR guys with folded trailing edges. Of course, the control surface
is larger too but I suspect the trailing edge shape to be contributing.
The F1 tail is a good option and probably the best option.
Good Luck
Tony

Be aware the early tail kits had elevators and rudders skinned with .016
skins, for a rocket you should use .020. Van has these.

Hi
I'm looking for advice on a cowl -- fuel injector servo clearance
problem. I have a HRII with Airflow Performance Fuel injector servo and
elbow. There is lots of clearance between the elbow and the stock HRII cowl
but when the Fuel servo is bolted on there is major interference between
cowl and leading edge of the fuel injector. Has anyone encountered this
problem?
I think a fix would be to have the elbow at an angle greater than the 95
deg. Is this what John's induction elbow does? As a last resort I could cut
the cowling but I really don't want to go there!
Any advice or comments much appreciated.
Thanks
Chris
Fordham

Not sure of the degree's in John's elbow but it is noticeably more than 90
degrees. I would call John, go to the source. KABONG HRII N561FS Do Not
