Messed up my right side tube gear last night and was wondering if there were
any around after upgrades. It also seems there was a Grove gear for sale a
while back. I'll search the archives, but let me know if anyone has parts.
Thanks. Ron NB Oregon KF IV Speedster

Ron,
If i ever bend my gear I will make a new gear a bit longer to i get a
higher AOA on the ground and would hopefully shave a few feet off TO roll.
Thoughts ?
I bet John Mc Bean would have a new gear quickly for you if you called him .
Grove gear to me is extra weight and I don't know what gain can be had by
using it but I have never flown with one eight but I have heard that for
the ones who have troubles handling a tame Kitfox with tube gear that the
Grove might help. ?

I started flying with the Grove gear, wheels and
brakes a week ago on a Kitfox IV Speedster with 912UL.
The original landing gear, consisting of
fabric-covered welded tubes suspended with bungees,
lousy brakes, one piece wheels and square shouldered
trailer tires, was a squirrly beast on takeoff and
landing, always wanting to dart off to the side.
After breaking a bungee on a bounced landing, I
decided to change it.
Now, it is all improved from the fuselage down,
aluminum gear, real airplane wheels, excellent brakes
and 6:00 x 6 airplane tires. It tracks straight
taxiing (even with feet off the pedals), taking off,
and landing. It is very stable. Land on one wheel
and it will settle onto the other. Get blown crooked
and a little rudder pressure brings it straight. It
is one piece, aligned straight when made. It is not
wobbly like a Cessna 140's steel gear. It is easier
to get in and out since it is not in the way as the
tube gear was. The Grove setup is a vast improvement.
It tamed the little beast and I can go to tundra
tires later if I want. I can't say whether it
affected the speed but don't think so as it seems like
it can still go pretty fast even without wheel pants.
I haven't determined the weight difference yet,
although we weighed the plane after installation.
I have no reason to keep the steel gear any more.

How could I find out more about this gear conversion, I am currently
installing a Jabiru 2200 and would like to make all changes at once. I do
not like squirley airplanes and anything to make them better is always
welcome. Jerry

Jerry-
I got my Grove gear during the building of my plane, thanks to this
group, and especially to Rex from Australia, who first suggested it to
me. The gear brackets fit into the tabs under the side of the fuselage,
and is very easy to attach...a one-man job. I got the rifle-drilled
gear, as it makes the brake line part of the job come out a lot cleaner.

Jerry,
There is nothing inherently squirrely with the tube gear. I had both. (For
those wondering, I changed out because I was having a hard time finding the
ground early on and was concerned with structural damage due to the limit
cables on the grear bulkhead. I know of guys that do not have the limit
cables for that reason.) Lots of posts on the list address opinions and
lots of the posts have opinions based on quite limited experience.
If you find your gear squirrely, it will be due to misaligned wheels. This
topic has been discussed in depth nearly every year or so. Toed in wheels
will result in squirrely ground handling. Parallel tracking or slightly
towed out will be fine. If you are landing well and then go squirrely, you
might try checking wheel alignment.
Just before we started the "Model, Engine" survey there was a long thread on
tri vs. tw gear. With lots of discussion about equally divided between nose
gear and tail wheel guys. The immediate implication to me was that lots of
guys had opted to go nose wheel - lots of list traffic in favor. The survey
showed that tail wheel is extremely predominant for those responding at
about 10:1. Those numbers suggest that tail wheel is not too difficult to
master by average pilots.
I suspect that if we added spring vs. bungee to the survey, my guess would
be that a majority of guys still fly with the tube gear with none
complaining. Neither is inherently better than the other. You can find a
mis-alligned spring that will be just as squirrely as a mis-aligned tube.
That is why they sell the angled shims to correct for misallignment on the
spring gear.
I have heard of other negatives on the spring gear besides wt. They are
shorter giving a more shallow angel of attack and quick off the ground is
not as good as with the tube gear. There have been comments recently about
taller tube gear for enhanced short field performance I hear that elsewhere
also.
In short it is all related to the mission of your airplane and personal
preferences. No one's preference is any better than any other's
preference - it is all just opinion. And this is just my opinion.

Lowell,
You laid that out very well.
And it was me that suggested that if I ever bent a tube gear that I would
build a taller one for higher stance and possibly shorter take off .
I am glad to hear that tube gear is safe from your viewpoint as well as
mine. I think second to mis-aligned toe in that pilot proficiencies is
lacking and causing some of this fear ?

and am getting john to look into getting another right gear built. this may help us both if they have to set up a jig to make the gear. i am thinking of upgrading to grove gear and would like any opinions on doing so.
