| Subject: | Re: Rocket - your TAS and stall speeds? Not book figures, |
I mean - yours
Hi Andrew,
You need to ask this directly of Tom Gummo. Tom loves his HR2. But his
claim is that he has the "world's slowest" Rocket.
I thought I found one slower than his, but it wasn't slow enough. 192 kno
ts 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 faste
r 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
the 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

| Subject: | Re: New Rocket Builder |
With respect to the stick issue, there was a recent fatal Rocket accident in
which it is alleged that the stick broke. The sticks in F1 Rockets are
aluminum and in most installations require a hole to be drilled toward the
bottom for the stick grip wiring to exit. It has been suggested that the
orientation of that hole and the aluminum material can combine to weaken the
stick the point that it is unsafe. Most RV's have 4130 steel sticks.
Soooo...a number of guys have been talking about replacing their sticks
with 4130. I'm not in a hurry, but will surely do it at annual time in
August this year. The stick loads on my Rocket do seem a bit high to me
(compared to my old RV-4), but that is probably a good thing...
considering....!!!
That is great news about Bosco! I'm really happy for him... please let ask
him to be sure to let me know when he flies it for the first time, although
I will probably see it on the Doug Reeves site. I'm sure he'll be a happy
camper!!
Regards,
Lee...

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.

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,
GAMI injectors, D Hartzell, big tires and pants. I max out at 210 Knots in
dicated at SL and 2700/28" 204 GS.---My favorite sweet spot though is
21/2300 below 5,000 feet just slightly LOP at 10 GPH 30 degrees advance tr
uing at 180 knots all day long. -That's better efficiency than my 160HP R
V4! -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?
