Not at all. Kolbs glide pretty well, though they're certainly not
sailplanes. What you lose in glide ratio you get back in the ability to
use a small field. A BRS is for structural failure, NOT for an engine
failure!
In the event of an engine failure, you need to get the nose down NOW to
maintain flying speed, because the plane is so light (and counteract the
pitching tendency when that high mounted engine stops pushing), but then
you're fine.
Dual is good, in at least something similar. It was some 15 years since I
last flew my Taylorcraft (or any other plane), a few hours in a 2-place
Quicksilver with a friend, and I felt ready to fly my Ultrastar. Except
for the landing speed and the need to flare at six inches, not six feet, a
Kolb flies more like a T-Craft than a Quicksilver.

Nice video. It is certainly possible to run a 3 blade 68" Ivo on a 503, my only
question would be - what was your cruise speed, and what rpm were you turning
at that speed? In order to get the 503 to turn 6500 rpm, you will need to take
out a lot of pitch, and then then your cruise speed goes to pot.
Back when I had a 532 on the MKIII, I started out with a 64" 3 blade Ivo. Given
that the 532 did not have as flat a torque curve as the 503, still, in order
to make the engine run properly, I had to run it with the prop in fairly flat
pitch and it had a great takeoff and climb, but at cruise it was turning 5800-6000
rpm with poor airspeed. Around 62 if I remember right. Took away one blade,
repitched the prop, and the cruise rpm became sane, cruise speed went up, and
it kept it's good takeoff and climb behavior.
With the 582 and a 68" 2 blade, cruise speed is 65-70 at around 5500 rpm and 4
gph. Takeoff is typical Kolb - great.

P, I'm not sure why you have the impression a Kolb with the prop stopped
"must be a handful". Other than a slight degradation of the glide by the
prop (mine has a three blade Warp Drive) my Mk III was no different from
landing it with the engine at idle.
If you do this, though, "collective down, stick forward, maintain rotor rpm
till just above the ground", you will definitely make problems for yourself.

No it isn`t. Its nice if a wing falls off but unless you fly over some
totally unlandable territory an ultralight has so little inertia and
flying speed is so low that you can usually find a usable spot. if it is
just an engine out just fly the plane to the ground.You are in control.
You are not once you have pulled the chute

And then there is the question of will you use it? You're in an emergency
situation where things have gone to junk as a result of your action or
inaction and now according to the BRS theory you will do something you have
never practiced, cannot preflight for, and do not know the outcome of
should you do it.
Case in point. The airplane from hell was recently sold to a fellow who has
a small runway on his property. According to what we know, the engine
failed on take off and the new owner flew it into a line of trees at about
30 feet off the ground. He may be out of the hospital now, we don't know.
The point is that he had the BRS handle right by his left knee and did
nothing with it, even though such a scenario is within the BRS safety zone,
according to BRS anyway.

Rick G/Kolbers:
Yes, I would use my BRS if the need arises.
I practice and have engrained into my mind what to do should
the need arise.
I also preflight the system, ensuring the safety pin is
removed and the bridals are in good shape.
I have faith in the system.
Quite a few folks have died because they never thought of
their parachute before they hit the ground. When something
catastrophic happens, one must react instantly in most
cases. A split second may make the difference between
success and failure, life and death.
Some situations the parachute probably will not save you,
such as the recent crash Rick G mentioned. No matter, if I
wasn't flying, I would not hesitate to pop the chute.

Below is a link to a video shot from an original Firestar. The last minute or so
shows a deadstick landing from base leg at about 500 feet agl. The glide angle
is not extreme. In fact, I can't tell much difference between glide angle at
idle and deadstick. I think what trips up a lot of pilots transitioning to
ultralights is the ground rush during the last few feet of the descent. If you're
not used to the wide visibility and the low to the ground seating position,
it feels like the earth is rising up to smite thee and the temptation is to
round out too soon. Without the engine to provide a burst of power, that can result
in dropping it in from several feet up. The trick is to fly it right down
the ground before beginning to roundout and flare.
