Thanks Smokey. Yeah, she's a great machine all right. Interesting you get t
hat SL speed at 2700/28". I don't normally run such a high power/rpm settin
g - I'll give it a whirl tomorrow though. We have the same engine, with abo
ut the same power. (Mine C4B5, 280 hp)
And, yep, as I think you know I use my Rocket for a lot of short strip stuf
f too. Surprisingly effective short strip machine.
Andrew
PS Would welcome any more data from Rocket drivers, whether HR, F1 or whate
ver

Hi Andy,
My HR2 is an oldie but a a goodie, 15 years old this year, 5th one to fly
. LyCon C4B5 approximately 285 ponies, electronic ignition on one side, GAM
I injectors, D Hartzell, big tires and pants. I max out at 210 Knots indica
ted at SL and 2700/28" 204 GS.
My favorite sweet spot though is 21/2300 below 5,000 feet just slightly L
OP at 10 GPH 30 degrees advance truing at 180 knots all day long. That's b
etter efficiency than my 160HP RV4! She stalls at 58 knots indicated with
flaps full.
The best part is coming over the mailboxes at my 500 meter strip at 65 indi
cated! What a machine, fair dinkum eh?
Smokey
HR2

Thx Jim. I've experimented w different rpms, and slower rpms seem to yield
slower airspeeds. Will experiment more. I do have a Hartzell. And will ask
Tom.
Any more takers? I'd appreciate it. Feel free to contract offlist.
Andrew

192 KTS true dosnt seem to bad to me? Thats 222 mph , at 15 gph that is 14.
8 MPG Sound great to me..... What is typical GPH at 200 mph ?

Hi Andrew,
You need to ask this directly of Tom Gummo. Tom loves his HR2. But his cl
aim is that he has the "world's slowest" Rocket.
I thought I found one slower than his, but it wasn't slow enough. 192 knot
s at 8,000' DENSITY ALTITUDE, full throttle and best RPM.
BTW, 2500 RPM may not provide the fastest speed.
A RV-10 with the IO-540 engine and a 3 blade MT propeller was 1 knot faster
at 2300 RPM (15 gph) than at 2500 RPM (20 gph).
The Hartzell "D" blade propeller will probably have peak airspeed RPM, and
I have seen this RPM decrease with increased altitude.
(Perhaps this is too much information?)
Regards,
Jim Ayers

Guys, a quick question? I know the official answers are on FAQs all over t
he place, but would like no-BS from the horse's (pilot's) mouth answers. My
HRII seems to give me about 198 knots TRUE airspeed, at, say 6000 feet, WO
T, 2500 rpm. I would be interested to know in your figures - TRUE airspeed
@ power settings, sea level and at altitude, plus whether you're flying an
HRII, an F1 (Hershey Bar) or F1/Evo/tapered wing. Also, what airspeed does
your aircraft stall at?
'Ppreciate it. I'm toying with upgrading, although my trusty steed has give
n me 700 happy and troublefree hours, and I wouldn't switch her out lightly
