| Subject: | Re: Dual seat Kolb flying in nw ohio? |
Hello fellow kolb owner,
I did exactly what you did, flew a champ and got a ride in a Standard Mark 3 locally
to get the sight picture.
I'm in california so thats a little far to go.
I would also recommend getting a flight in a cub, especially for landing speeds.
As others have said, keep some power on as you approach and be prepared that you
will be much lower than the champ when you actually touch down.
With power on you can stay flying that last foot or two as you "Feel" for the runway,
then ease back on the power and your there..
After getting past those first few landings, then start your training with less
power and you will see that once you round out near the ground your speed will
drop VERY fast, so its crucial that you know your close to the ground at that
point.
This becomes one of the best things about the Kolb, dropping in nearly directly
over the runway, no power , very steep approach, round out right at the runway,
slow down, land in less than 400 feet. Feel smug as you taxi off the runway
as all those other planes land long.
Good luck, your nearly there..
Frankd

The lead acid battery in my Firestar II leaked acid into the fuse and layed on
the fabric for days. It did no damage which is a testament to how strong the fabric
is. I cleaned it with vinegar & water. The battery was upright and acid
was forced out the caps. I had the plane out in the Arizona 90*+ heat for a few
days with a white towel over the battery but found the acid leak when the plane
was at home under shade and I'm guessing the heat swelled the battery causing
the leak? The former owner put in a cheapo from China Mart (Walmart) No way
am I putting that battery back in the plane and risk another leak. In research
I came upon Lithium Iron batteries. The weight savings is amazing. The old
lead acid weighed 11 lbs. and the new Shorai Lithium-Iron Battery LFX14L2-BS12
weighs only 1.46 lbs. It was hard to spend the extra money but I did, $144.00
for battery, and I ordered the balance/storage charger also for $77.00 My Firestar
is on the heavy side and I'm glad to take 9.54 lbs. off the weight. These
Lithium Iron batteries are said to have more starting power than lead acid for
the same amp hour rating. They are said to take more heat and last about 3
times longer, are sealed, and can be positioned any way you want with no danger
of leaking. Was wondering if any other Kolb owners have looked into or purchased
one of these newer Lithium Iron batteries? It can get confusing with amp
hour ratings, but the specs for Rotax starter battery says minimum 16 Ah and higher
is better. The old lead acid was 11 Ah and started the 503 just fine. The
Lithium Iron I ordered is 14 Ah but puts out more power than lead acid so it
should be better. When not using a lead acid it should be kept fully charged,
but Lithium should be stored at 70% to 80% charge to extend it's life which is
why I ordered the charger/balancer with 'storage' feature. I ordered mine from
Rocky Mountain, an ATV/Motorcycle supply place. I found when you look for 'aircraft'
Lithium Iron batteries the price goes up of course. Battery Mart carries
them !
for $152
.00 but for $144.00 I got mine here... http://www.rockymountainatvmc.com/p/44/54/227/730/5796/31299/Shorai-Lithium-Iron-Battery

| Subject: | New Firestar battery Lithium Iron 1.46 lbs. |
this is the type of battery I am using..
http://www.arizonabattery.com/?page=shop/flypage&product_id=58&category_id=b291dca6cea297f2a41f49052a63d38d&
.. I found one of these in an ups (uninterruptable power supply ) that
had a split down one side across several cells and there was no leaks or
damage to the ups. at $40.00 it is cheap. .... when I first built my
mkiii I bought a "quick start" from harbor freight for about $35.00 and
used the battery in my plane. it was still working 5 or 6 years later.. I
ordered a replacement battery from harbor frt for the quick start,,, seems
it was only 16 dollars. so I ordered 2,,, one for the plane and one to put
back in the quick start, it took a long time on the boat from china.
seems the freight was under 10 dollars for both. the second is going on 6
years.. if you order from Arizona battery, it will be there in 3 days or
so verses the 3 months from china.
the Lithium iron sounds intriguing. if they last 3 times longer, it is
still quite a bargain, provided 3 times means 3 x 5 years,,, not 3 x 1
year. and the weight savings is good... my plane could loose that much
weight if I would put less popcorn in my mouth....
