Any C of G problems?Don't know about the wright of the metal tank, but I don't think there's be a significant difference in CofG, since the tank is near the CofG.In my case I really needed a change, cause the Cof G of my aircraft was way aft when I bought it. Needed a lot of forward stick to keep it level. I weigh only 170lbs and the previous owner was maybe 100 lbs heavier, so it was way out of balance with me. The original two 5 gal tanks were in the regular place, behind the center of lift. I worked out that this new tank, in place of the pax seat in the FSll, right behind the pilot seat, worked out just right. Now it flies hands-off just perfectly.JG* ________________________________ Message 2 _____________________________________ Time: 03:26:07 AM PST US From: "Pat Ladd" Subject: Re: Kolb-List: Re: Larger, one-piece fuel tank for a Mark-3 Hi JG, I forgot that you do not have a limiting weight to define the machine as an ultralight as we do in the UK But I would suggest that you do an accurate `weight and balance` calculation after you have the tank fitted. "Not much change because its near the C of G is not really good enough." If she stands on her tail and you can`t get the nose down you may wish you had done so. If you are a real lightweight it may be worth carrying some lead. I fixed some in the nose of my Xtra (Make sure it IS fixed.) I cut sheet lead into approx 4"X4" squares until I had the weight I required. Drilled a couple of holes through the pile of sheets and fixed then in the nose as far forward as I could easily work through the fibreglass. I put a piece of ply between the lead and the nose cone to spread the load and used big washers on the outside for the same reason. When I was gliding and the gliders were being used by club members of different weights the women, who tended to be the light weights had their own cushions with a piece of lead inside. It worked but becaus e the pilot tended to be near the C of G the weight required was sometimes large. Better to have a little weight well forward. Hope this is useful.

From: "Arizona Flyer" On my Firestar II the pizza cutter tail wheel is worn. I bought a new one from Travis at Kolb. I tried to take the old wheel off but it won't budge. It seems like the wheel collar is press fit onto the shaft? I could remove the snap ring and just install the new wheel, but as long as I bought the wheel fixed onto new bearings I'd like to use the new bearings also. I've banged on the wheel collar trying to get if off the shaft but afraid of doing damage. Is it a press fit onto the shaft? I bought a snap ring pliers to just replace the rubber wheel but having a hard time getting those snap rings to come out of the old & new wheels.

Tail wheel bushing will rust to the 4130 chromoly axle. Beating on it could deform the chromoly tube and make it more difficult to separate It will probably take a press. You might try heat. Good penetrating oil like Kroil: http://www.kanolabs.com/ Kroil beats all the others I have tried. john h mkIII Titus, Alabama ________________________________ Message 6 _____________________________________ Time: 06:18:05 PM PST US Subject: Re: Kolb-List: How to remove tail wheel? From: Gary Aman The tail wheel looks like it's pressed onto a short tube that slides into t he larger pivot assy. tube.You had to drill a hole through both and put a c otter pin in it to keep them together.I'm sure they rust together eventuall y.Look for that pin,I think it's on the pilots side of the assy,and you can probably see a tube in a tube from that side.
