Kyle, you are entitled to your opinion but if you
need more than 140 mph or 3gs to get over the top
of a LOOP you are doing it wrong. Pulling MORE
g's than 3 will cause more loss of airspeed. If you
are flying faster than 140 mph that's fine, but NO
one needs to do that and it's MORE hazardous to
fly fast aerobatics as the load factors increase. In
fact a 2.5 g's initial pull up will work at 120 mph
depending on weight, 140/3g's is plenty.
ITS NOT A MATTER OF GETTING OVER THE
TOP ITS A MATTER OF MAKING A NICE ROUND
LOOP.
Now you did remind me of one thing, I forgot to
mention. I have a constant speed prop. For those
with fixed pitch prop you may consider adding
power after starting a LOOP and reducing it on the
back side to maintain RPM, to get max
performance. HOWEVER my basic advice is valid
for typical RV's. I know I've flown a 1/2 dozen
RV's. Stall? so what, recover. If its buffeting on the
top release back pressure, it will go over the top.
Constant speed props really shine doing aerobatics.
Rolls are not and issue because the airspeed remains
fairly constant, but with a fixed pitch prop, as the
speed decays/increases, throttle adjustment is needed.
As a CFI let me tell you I would rather have my
fellow RV'er follow my practice and self
evaluation and guide lines (g-meter, min alt 3000
feet, max speed 140, max 3 g's) than have some
knowledge than NONE. You say internet advice
like that is a slam. I have well over 1000 hours in
RV's, total time about 15,000 hours. I clearly
recommend getting some dual and reading some
basic acro books. However 30 hours of Acro dual
is a lot.
MANY MANY pilots have taught themselves
basic acro. To deny it and make it secret info is not
going to change the reality, people are going to try
it. I would rather they have my advice than
nothing. Bottom line know thy self. If you are a
weak pilot, have a hard time landing and taking off,
you can't do private pilot maneuvers within the
standards, than ACRO is not for you. HOWEVER
acro is what RV's are about and they do make
better pilots. Acro has risk, but solo at 3,000 ft
is not high risk if you use your head.
I think my step by step practice and advice is good.
Take it or leave it.
Cheers, George

RV-6 with a 160 hp engine and a cruise pitched prop,
I do not believe the airplane would make it over the top
of a 140 mph/3 G loop. Instead, I'd get to experience a
full power departure stall while inverted. My entry speed
and initial target G are both higher than 140/3...If you
want to use internet advice for acrobatics (which ain't a
good idea, by the way), make sure you are talking with
someone who has an airframe/engine/prop combination
that is very similar to yours.I'm sure a light RV-4 with a
constant speed prop can be looped from far slower speeds
than my airplane.
