Um. Clearly Smokey got in first, but if he's not interested, I might be.
I've long been a little concerned about the tail on my Rocket. Hard to
keep the thing below VA or VNO, in turbulence, when she's so FAST 
Incidentally, Tom's post has me thinking. I'm not sure how his Rocket is
only good for 170 knots, but I'm presume there's a good reason. I've
always thought mine was a tad slower than the numbers I've been reading
- when people ask me how fast I cruise, I tell them, being
pathologically honest, I cruise at 199 knots TAS. I've read about
Rockets that cruise a lot faster than that...210 knots seems to be a
common figure. I can't get more than 200 knots TAS under any
circumstances, maybe 205 at sea level, 2700 RPM, WOT and full rich,
which is an expensive way to get another 5 knots. I've got a Lycon IO540
C4B5, slightly tweaked to produce 280 hp, and a light (VFR) airframe.
Anyone got any thoughts on how to get another 10 knots out of her?
I HAVE noted one thing which makes me wonder. At any sort of cruise,
there seems to be quite significant forward elevator. The front part of
the elevator (the horn?) seems to be an inch or so above the front of
the HS. If I was to tweak the incidence of my HS somehow, to get to a
point that the elevator is neutral at high speed cruise, would that
likely make her a little faster? I have two aerials, but otherwise a
clean airframe. Anyone got any ideas on getting a little more speed?
Feel free to email me offlist, andrew at active new zealand dot com.
(Anti spam version - u guys can figure it out
Also, GREAT to see the outputs from the OSH safety seminar. Lots of food
for thought. Thanks very much, everyone who contributed...

PS standing invite to New Zealand for Rocketeers is always there. Best
Rocket flying in the world is down here in little old New Zealand, I
reckon, if you'll excuse the parochialism. As you guys head into winter,
if you're keen on a cool holiday and some kick-ass flying, well, you're
talking to the right guy! Google Active New Zealand, or add a dot com at
the end, and check out the sort of stuff we get up to down here in NZ.
The hiking's great....but the flying's sublime!!!

It's yours Andrew, thanks to Rick for advertising them. I'm building a set of larger RV4 elevators. According to someone who built a set, it makes the Rockets pitch authority similar to a light nose RV4. I'm also purchasing a HS from a friend who built an RV4 tail with the F-1 mods.
More speed is cool, but maneuverability, pitch control at low speed (landing on my 1800' strip!) are higher on my list. Heck, mine will do 200 knots on the deck at 27 squared now, big tires, old airframe, 15 year old deceased insects and all.
Been to NZ, neat place, next time I'll call!
Fair Dinkum!
Smokey
