Hi Everyone.
Last weekend yielded the best weather I could have hoped for, warm,sunny and no
winds to speak of. I took my FSII to nearby SFZ where from the Airport manager
on down the line could not have been more friendly and welcoming. They set the
stage for what was a great experience. I got things together, taxied out to
the 5000' runway added power and off I went. I planned using 55mph for climbout
and was amazed at how quicly it accelerated and climbed at that speed. Iflew
around to get a feel for slow speed handling and found it stalled at 40mph dropping
the right wing. Using flaps (yes my FSII has flaps) yeilded only slightly
slower (38)stall with a more pronounced wing drop. Flaps were not used for
remainder of flights. Landing approach was done at 55mph which setup a reasonable
decent. Reaching around 50" I added power to arrest decent, with a flare
around 10' settle to runway and BAM! right up on my nose. [Rolling Eyes] Lesson
learned is make sure you put your size 10 heels in front of the heel brakes,
not in front where comfort dictates. No real damage other than to pride and
bent antena and road rash on cowl. As of yesterday I've put in 8 hrs of time
with a mix of landings from dropping in and respectable. the gear may have
suffer from some. Any way to straightren aluminum gear? Whats the options and
possible vendors? ...Bob

""Lesson learned is make sure you put your size 10 heels !
in front of the heel brakes, not in front where comfort dictates.""
If your heals are hitting the brakes at the same time your toes are on the
rudder pedals....... Here is an idea to think on,,,, only an idea....
If you shorten the rudder cables it should bring the top of the rudder
pedals closer to you / or more over the top of the brakes. Now in order
to hit the brakes you will have to pull your toes back towards you in order
to reach the brakes with your heals... So if an event requires you need
both, you won't have to lift your heals over the pedals waisting time...
Or on the other side of things you could reposition the brakes further
forward... Either way the geometry would be the same.
The choice may depend on the legnth of your legs and which is more
comfortable.
Just think on it.

The gear can be straightened. Most people use a cheap hydraulic press (Harbor
Freight) or a home made jug with a hydraulic jack. Some guys get a set of spare
legs from Kolb. Others have made steel legs, but if you are still learning,
the aluminum ones put less shock on the airframe in case of a goof.

Wait until Harbor Freight puts this on sale, fix it yourself.

In the meanwhile, take the leg to any machine shop, they can straighten it for
about $20 if it is not badly bent.
Attached is my collection of old Firestar/FSII gear legs. The top set is from the
original Firestar from which we built the FF clone, and I would consider them
un-straightenable. The next 3 down all have slight bends and could easily be
fixed with a press in just a few minutes. The bottom one is unbent.

Looking at Richard's pics of gear legs; has anyone ever made a set of
steel legs that don't have any taper? In the RV-x world, the Harmon
Rockets use titanium legs with no taper, but supposedly, titanium's
flexing characteristics are different enough from steel that they can
get away with no taper. Making an axle adapter to fit the fatter leg
cross section wouldn't be that big a deal, but I'm not sure about
transferring extra impulse load directly into the gear sockets if using
non-tapered gear.
Thanks,
Charlie

Hello to fellow Kolb owners. Name is John from Northern California, just completed
a FS ll and have been reading all your great comments about building and flying
for about 2 yrs. while finishing my project. I'll be asking for lots of
advice.
Listening in on the gear leg issue...I was wondering if any sort of bungee cord
arrangement like those found on bush planes could absorb some hard landings,
maybe a spring steel leg? ( Maybe steal the front shock struts off my wife's car)

To answer Charlies's question, yes, there are a lot of straight 4130 Kolb g
ear legs out there.
My Brother Jim and I fabricated a set of non-tapered 4130 legs for my origi
nal Firestar in 1987. That is all I have flown on since. In fact, we used
parts of the FS legs to build legs for my current MKIII in 1991.
Don't know of any other Kolbs with steel legs back then. Homer and Dennis
were interested at the time. Just another trick Jim and John Hauck came up
with. ;-) Old Kolb designed a tapered solid 4130 leg that was not near t
he performer ours was/is. New Kolb came up with non-tapered legs with a be
nd to get the nose of the Kolbs higher and in a better 3 point stance.
John Bickham designed and built the first set of non-tapered 4130 legs with
bend for his MKIII, before New Kolb copied his design, or should I say ca
me up with legs just like John B's. ;-)
Should be lots of info on the steel legs in the Kolb List Archives.
I'll see if I can find a photo of the FS and MKIII legs and attach.

Good afternoon Kolbers. I have a Twinstar MKII that I am redoing and looking for
some pointers on the aft cage tubing bending and fastening. I have scoured the
build manual and plans and photo build manual and don't find any details on
the shape to bend the tubing to. Riveting and gusseting is described but nothing
on shaping. Any and all input will be greatly appreciated. Thanks in advance.

I think so. The reason we "lost" 7075 alum legs 30 years ago.

....So the aluminum legs will sooner or later become a lost cause?

Thanks, John, for both the info & the pics. Getting the nose (& wing
angle of attack) up is the primary reason I was asking. Much easier to
fab a set of legs without taper. I even looked at just making them
longer, but to get any height benefit, they'd need to be quite a bit
longer on the old Mk I; the angle is fairly shallow compared to the pics
you posted.
BTW, any of you guys that are 'in the neighborhood' of Jackson MS next
weekend are welcome to our annual Pumpkin Drop here at Slobovia
Outernational (MS71). I sent a flyer to the list about a month ago, but
if you missed it, just write me off-list for flying and/or driving
directions. Early forecast is for rain, but we all know about forecasts. :-)

;-) Old Kolb designed a tapered solid 4130 leg that was not near the performer
ours was/is. New Kolb came up with non-tapered legs with a bend to get the
nose of the Kolbs higher and in a better 3 point stance.

I'm not sure about transferring extra impulse load directly into the gear sockets

Bob, As Bill said, yes they can be straightened, but they will be a bit
softer each time and thus easier to bend. Make some saddles out of PVC pipe
to protect the leg from getting a ding when straightening and have at it
with Mr. Hydraulic Press.
When Travis was at Kolb he was the best at supplying answers to Kolb
questions even though he didn't fly. I told him my problems with landings
and his advice was to wheel it on at first rather than trying for a three
point landing, When you can wheel it on consistently then start slowing it
down a bit until you find the sweet spot where she just sets down on three
and rolls out. It's like riding a bike; once you get it, you'll always be
able to roll it right on every time. It just takes a little practice.
Congratulations, sounds like you're having fun with your Kolb. I may be a
little prejudiced but I think it's the best flying fun there is.
Blue skies,
Rick

I've straightened the tapered steel legs from an RV-4 in a HF press
using soft pine 2x4s as pads. One under the ram, and the leg resting
across a pair of them. With the steel legs, the wood crushes enough to
spread the point loads of the ram & support points.
