From: "Dennis Thate" 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 -------- Both optimists and pessimists contribute to our society.

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.

I do not imagine you would be far from gross and that is without a passenger. Then if you do not use the reduction on the vw you will have even worse performance then the direct drive Jabiru. The reduction adds about another 20 pounds but you can ask as I know there is atleast one on a kolb on the list. > > Travis Bennett > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=355689#355689 > > > > > > > > ========== > arget="_blank">http://www.matronics.com/Navigator?Kolb-List > ========== > http://forums.matronics.com > ========== > le, List Admin. > ="_blank">http://www.matronics.com/contribution > ========== > > > > > > > ________________________________ Message 4 _____________________________________ Time: 10:56:18 AM PST US From: "Nick Cassara" Subject: Kolb-List: Re-enforced gear legs on John Hauck's Mark lll 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 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. john h mkIII Mobile, Alabama Could you post a picture of the gear reinforcements you and Jim made when you built you Mark lll?

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.
