My FireFly came with a 447 and C-box 3:1 ratio, so the prop was a big
three-blade job that wouldn't fit in the trailer. So I just removed the
prop each time. Socket in electric drill and torque wrench handy only took
a couple of minutes each time. Maybe you could consider a 4-blade used that
way....
I did that for quite awhile until I could find a B-box. With 2.58 ratio and
two-blade prop it went better but more vibration and noise....
Have you done a good 4-way GPS run to check the ASI?? GPS readings don't
have any real value unless you do a complete 360 circuit on a steady
day.....

Bill, have you verified ignition timing is correct? That could explain a lot
of things.
Also, you were concerned about getting your Firestar up on its nose. The Firestar's
main wheels are located well reward as compared to most other taildraggers.
I believe this makes the airplane less twitchy; however it can nose over
more easily. BUT, the only times I had this happen is when getting stuck in
tall grass or mud and trying to power out using the engine to unstick.
For lazy people like me nose bowls and nose art are temporary expendable items.

Hello Bill/ Kolbers
Seems like there is some progress on your thrust issue, your combo of Gearbox and
prop is an area to work on.
Do you still have your extended exhaust pipes and exhaust under the boom. Maybe
that is creating alot of drag to slow you down. It sounds like your engine is
running well so the exhaust may be working well and not robbing power, but the
added tubes and stuff out in the airstream must be a drag source.
Maybe you can take the exhaust off for a test (No cost, just very noisy).
Also, your alignment of wings and Horizontal Stab is working, you have proved that.
One thing you did not confirm is the angle of the boom tube to the ground
in flying position. IF that was wrong and set too high at the tail, your angles
of wings and Horz will have to be adjusted to offset this boom angle. And
this is exactly how you have rigged your plane. You have assumed the boom was
set correctly at the factory but maybe something is off and this is an incorrect
assumption.
These are thoughts about your situation and as stated before worth what ya paid
for it.

The timing is electronically controlled by two black boxes, one for each ignition
system. No adjustment, no possibility of errors.
My aircraft has significantly longer gear legs than any other Firestar. So because
of the mounting angle, this puts the wheels a little further forward than
they wouuldotherwise be. It is controllable for someone with previous taildragger
experience, but probably not as easy and gentle as the stock Kolb.

Fuselages are welded in a jig. Be pretty difficult to get the tail boom
angle incorrect.

Bill,
I have a 670 Rotax Rick engine with a 4/1 ratio C box on a Mark 3
Classic. It has a 3 blade 64=9D Ivo MEDIUM prop. I have derated my
670 by lowering the compression ratio to produce no more than 80hp @
6500 rpm. 6500rpm divided by 4 gives me 1625 prop rpm on climb out. I
cruise easy @ 4500-5200 engine rpm, 1125-1300 prop rpm @ 55-65 MPH
I believe you could get optimum performance from your engine and gear
box with an IVO medium prop.

the Arplast because I need a large blade area (wide chord) to absorb
58HP within a diameter and RPM restriction. I have a 3.47 to 1 gearbox
on the engine. The prop RPM is so slow that I need all the area I can
get to absorb that power. If I had the 2.58 gearbox I would be able to
turn a 64 inch Ivo or Warp Drive prop at higher RPM like most Kolbs.

I just started to rebuild my barn find FS2 and the original plans show FS100 also,
You may need to sand the end of the tube lightly to bring up numbers mine
is marked F1002 with the latest revision 1993. I have been in touch with Kolb
and they are going to see if they have records from that time period.
If there numbering is as most manufacturers use the "F" is the model The "1" is
a control number and the last three Or four would designate build number.
I could be completely WRONG! I will update when I find out. :P

Sounds like the same as mine.
Firestar II has a 7 rib wing design with apparently the build number stamped
into the root tube end plate.
A friend and I built mine from a kit and plans in 1985/86. First flew it in t
he summer of 1986. It=99s a great little original Firestar. It=99
s been upgraded a bit since the early days.

My first one had the number FS11 it was built in 94, and its my
understanding that it was the identification of the cage not a build
number. I still used it as my serial number :-)
