| Subject: | the aft cg club... |
My 503 Rotax Kolb Firestar II is built per plans, even at my meager 220 pounds,
I have a aft CG.
What are my options to get back in the envelope ?
How is the wing cord measured on a Firestar II, does it include the aileron or
just the wing ?
Thanks

Thanks everyone who chimed in on engine choice, on-list and off. Re-drive
type engines seem to have an advantage when it comes to developing torque at
low prop RPM, which is the main concern for water operation. But unless I
can find a used 912ULS, a 4-stroke Rotax is out of my price range. Guess
I'll be looking at small auto conversions or Hirths with re-drives.

Check out the Viking engine. You could be the first on a Kolb!

John,
Could you post a picture of the gear reinforcements you and Jim made when
you built you Mark lll? I remember you saying that you repositioned the
legs, but I have never seen a close up of the reinforcements you added to
the base of your gear legs.
Thanks for sharing all you travels with us.

I'll see if I can find a photo. I am away from my PC and other files and
DVDs.
The main gear was moved forward 8". A 3/4" 4130 square tube bridge was
fabricated inside the fuselage under the seats.
This puts a lot of weight on the tail wheel, making the MKIII a true tail
dragger. One has to stay ahead of the aircraft on the ground or she will
ground loop in a heart beat. On the other hand, I have never had a problem
of my MKIII trying to get the tail up and nose over.

Alright I bite and play your game. How much are you wanting for
it. What is it with people, why would you go through the trouble of
placing an add and not include the price up front. Sorry folks but
this just doesn't make sense.

I think what happened was you read the post faster than I could edit it. I saw
that too so I went back in and put a price and the Firestars location in the
edit a short time after the original post.
I am interested in a fair price for the plane. Like I said I would like to get
6k for her but I am willing to take offers.
Sorry for the mix up
