| Subject: | Re: Firestar Re-Configure Project |
Since I just happen to have two Kolb's on premises, I went out this morning and
measured the angles on both of them. To keep things consistent, I raised the
tail on the Firefly until the motor mounts were at 0 degrees - level - and then
measured everything else relative to that. Since the hangar the MKIII lives
in is on a slope, the motor mounts were within 1.7 degrees of being level, so
I simply adjusted the numbers accordingly.
Also - just for the record, the Firefly was rebuilt from an original 1985 Firestar
- it still has the original full size wings on it - so the numbers listed
are for what a Firestar was back in 1985.
Firestar:
Motor mount = 0
Wing = 3 degrees
Stab = .2 degrees
Main tube = -6.8 degrees
MKIII
Motor mount = 0
Wing = 7.1 degrees
Stab = 1.8 degrees
Main tube = -5.1 degrees
Quite a variation, both of them fly excellent, the Firestar/Firefly cruises at
55 at 5500 rpm with a 277, will top out at 70, so it doesn't take a lot of horsepower
to make a Firestar go fast.

The angle of the wing is approx 12 degrees to the boom on firestars. Level the
boom and the wing should be that. If it is not, check wing attach points. The
sling shot is the only kolb with different angle, 9 degrees which is why we
have long gears. Now, i may be wrong on the Mk models but i do know firestars.
If yours is different, i believe therein lies the problem. Worth what ya paid.
The advice to start from scratch and such i think is good. Just remember
this question, how long are you planning on staying dead? Ted cowan SS 912ul

Richard,
I notice that the difference on my wing to stabilizer is 8.2 degrees to yours is
8.9 degrees. Essentially the same. The Firestar is definitely a different
animal.

Sorry, I added when I should have subtracted. Your difference is 5.3 degrees.

Early this morning Larry Cottrell flew over to the ranch to check cows. He
did a flyby for me and my son Mike. Love the sound of the little HKS
working. Larry said he was turning 6000 rpm when he buzzed us.
Got here last night. Waiting on the rest of the crew to show up. Beautiful
weather, perfect for flying. Warm days and mid 40s at night. Good sleeping
weather.
I tried to attach the video to an email, but Matronics would not accept it.
Let's try it this way. A url from Face Book:
