Back in the day, 1984, Homer said you could hang the US from a rafter at the main spar carry over tube, sit in the seat, and should be close to balancing. Most of us never went that far. If the US is built to plans it will be within cg. There was no published cg procedure for the US, during that early time period. Most of us would have only gotten confused. Climb rate with a ULII02 is quite impressive. It is happy to climb at 25 mph max rate which is right on the stall. What that max rate is, I do not know, but it is no slouch. I have no idea what max gross weight is. I weighed about 180 lbs and had 6 and 1 3/4 gal fuel tanks. It is a good little airplane, but is also early 1980 expertise. It has some weak points, depending on what model of US you have, and has disavantages like a lot of other airplanes. I do not have time to go into that now. Maybe later.

At the moment, I am on coffee break. Shot the last Pontiac Red Aerothane on the center section parts and gear legs. Now I have to wait for tomorrow to get them moved in a very, very safe location until they cure a bit and I can get them riveted together. This is the time the BRS 1050 soft pack goes in the front of the center section under a sheet of frangible haircell plastic. I use silicone seal to seal the plastic to the sheet metal, then pop rivet it in place. It will remain here until 2013 or sooner if needed. Using this system for the ballistic recovery system has a lot of advantages: 1-completely inside the airframe, even the rocket. I lowered it 5 inches to get it under the plastic. 2-out of the weather which stretches the softpack life to 6 years. The rocket is good for 12 years. What were the other advantages? I forgot. Tomorrow or Thursday James Tripp is coming up to help me sit the engine on the airframe. When I get all the hoses, wires, cables, etc., installed, I'll then start on the lexan. When the lexan is finished, the gear legs go back on the airframe, the airframe is hauled to Gantt IAP for wing attachment, final preflight and test flight. Think I can get all that done before time to go to Lakeland? Probably. This is a usual time line. Get it ready to fly the day before time to load it up and haul ass for Sun and Fun. hehehe Take care, john h mkIII ________________________________ Message 13 ____________________________________ Time: 11:30:40 AM PST US Subject: Kolb-List: Re: Kolb Ultrastar W & B From: "JetPilot" jb92563 wrote: > Does anyone know where the CG range lays on a Kolb Ultrastar? > > What sort of rates of climb can I expect in the U-star with the stock Cuyuna 430 at Max gross weight? > > Thanks, > > Ray Did you want the climb rate before or after that Cuyuna quits :) -------- "NO FEAR" - If you have no fear you did not go as fast as you could have !!!

Its encouraging to hear that the climb rate is good. My last Ultralight was a Lazair with about 400 fpm climb. I recently sold it because I wanted something that could handle a bit more wind(Headway) and stores easily. The Lazair cruised at 35 and the winds were typically 10-15 so it took a while to get anywhere....even when staying local. I figure the US will add at least 10mph to that and have a better rate of climb, plus with the short wings it will feel more sporty due to the roll rate. I also have a Moni which is great for going farther fast as it cruises at 90mph on 30hp and is of similar span....It's the sportscar/motor glider of the fleet.

The Ultrastar is a good flying little airplane with a slow roll rate. All the Kolbs except the Fire Fly and Sling Shot are slow in roll. If you want one to roll up quickly, get a Pitts. You are in the wrong game. One improtant thing to remember flying the Kolb is not try to force the roll. Gently move the stick the way you want to go, and it will roll. Weak points of the Ultrastar are: -Low prop. Catches a lot of grass, weeds, rocks, or anything else it comes across or goes through. -Homer's belt redrive has a weak prop shaft bearing. He used caged ball bearings. Double tapered roller bearings would have been much better and given the operator a way to set bearing adjustment. -Has a 5 rib wing which gives good performance and reliability if kept withing the flight envelope Homer dicatates. -Wing will twist around the main spar when aileron input is too great. Effectively cancels out input. No big deal though. My old buddy that flew B-47's in the Air Force said that bad boy did the same thing. First time I heard that from him, I cracked up. Homer designed the Ultrastar for very slow flight. It does that well. It will also fly 85 mph straight and level WOT with a ULII02 and a Jim Culver two blade wood prop 50" X 30". The fuselage is lightweight and it has rigid gear of thin 4130 tubing. Easily bent if you drop it in a foot or two, especially if the wings are not level and it hits on one gear. Frequent engine failures in a Kolb will make a damn good pilot at out you, especially executing successful forced landings. In the early days, if you flew a lot, you had a lot of forced landings. I am probably way behind the power curve on forced landings now days. john h mkIII ________________________________ Message 19 ____________________________________ Time: 03:23:18 PM PST US Subject: Kolb-List: W&B From: "Paul Petty" Gang, Got this in a fax from Donnie today.

I put contaminated fuel in my tank from an unreliable source. Both times I considered them reliable sources, but had a rude awakening. First time was a considerable amount of water. Second time was tiny nylon fibers from a brand new fuel pump that had not been flushed before selling fuel. Guess what, I flushed the system for them by buying the first 10 gal of gas. The fibers overpowered my fuel filter. Both cases could have been prevented had I done a fuel sample after refueling. My fault entirely.

I have the original manual for the Ultrastar, it says, with the pilot in the seat it should balance at 25% to 30% of the wing chord. This translates to the balance point being located in the range from 16" to 19" from the leading edge of the wing. To check the balance, hang the Ultrastar from a point within this 3" range, and with the pilot in the sitting in the seat the plane should balance. The fuselage tube will be at a 10 to 12 degree angle (tail lower than front) when the airplane is considered balanced. Hope this helps. Dan Walter Palmyra PA.

If I had your ultrastar with the Cuyuna, I would definately fly it. The Ultrastar will land really slow, and should be able to land just about anywhere. Just practice power off approaches and landings, get your landing skills down pat so that you will be ready when it happens, and try not to fly over unlandable terrain. There will always be times when flying where you will just be plain screwed if the engine quites, but I try to keep that to a minimum.

A rough way to say it, but close enough for gummint work. CG should fall between those two points. The rest doesn't seem to make any sense. You can do the w/b by picking your own datum somewhere in front of the wing's leading edge & measuring from that point back to the wheel centerlines, fuel tank, engine oil tank centerline, seat, etc. to get the 'arm' for each one. Isn't there an RV-x close by? Can the builder help you do the w/b?
