When I got back into flying after retirement I went from a CH701 --> Cherokee 140 --> Early FIrestar --> Titan Tornado --> Allegro LSA. Of all these, the FireStar and the Titan were the most fun because of the great visibility, the Cherokee 140 the least fun and by far the most expensive. Last annual inspection was over $5k and there was nothing big wrong with it. Sold it immediately after that. Sharing overhead and up front costs with one or more owners can be great. I'm now in my second such deal. One thing no one else has mentioned that is worth considering. What will be the "partnership" deal with you and the other 150 owner. Our Allegro is owned by a corporation we formed to limit each owner/pilot's liability if one of the other pilots does something stupid and gets someone killed. The PIC and all owners of an airplane will definitely be named in the lawsuit that results from a bad accident. If you have any assets you'd like to keep, like say your house, then you are risking it if you do not have some sort of limited liability ownership form. An LLC is supposed to offer this sort of protection as well as a corporation, I'm told. If a corporation or LLC owns the airplane then the non-PIC pilots/shareholders do not risk their personal assets, only their share in the corp/LLC. Another advantage of a corporation is that if any of the shareholders want to sell their share it is not a sales tax event.... just like selling shares of Wal-Mart stock. I am not a lawyer and this is not legal advice just something to consider when sharing ownership of an airplane with others.

Jim...while I am considering the FF in Texas....and have the inspection report back on same...it sure makes sense to consider yours here on a more local level as well. If you decide you are really happy with the concept of letting go of it then maybe we should get together.

Well, believe it or not, I am in the process of buying 1/2 of a Cessna 150 and am starting work on my GA ticket. I have a new wife and daughter that I brought to the US from China 3 months ago. When we were in MV in May, Dave Rains took us all up in his C-175 and we had a great time. I now find I don't go up to the airport much and when I do go up there I don't fly very far. I don't see any long trips with plane and trailer like last year in the future, so I've decided to go the GA route and later I can fall back to the Sport Pilot rating if desired. I think I will learn alot getting my GA ticket, which will be inexpensive since all the lessons are part of the deal on the plane, making it too good a deal to pass up.... the plane is also 10 min's from my house, compared to 50 min's to the airport where I keep the FF. After one flight in the 150, I can see I have a lot of adjustments to make and get used to. The most striking difference is the glide slope approaching the airstrip! [Shocked] Eventually I will probably sell the Firefly and trailer, but am in no hurry on that until I'm sure I'm doing the right thing. Am I totally crazy or what? :o -------- Jim Hefner Tucson, AZ Firefly #022 447, 2 blade IVO, BRS-750 Do Not Archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=43365#43365 ========================= ========== http://www.matronics.com/Navigator?Kolb-List ========================= ========== ========================= ========== http://www.matronics.com/contribution ========================= ========== ________________________________ Message 3 _____________________________________ Time: 11:08:44 AM PST US From: "JetPilot" Subject: Kolb-List: Re: MkIII, suzuki G10 --> Kolb-List message posted by: "JetPilot" The Suzuki engine seems like a really great alternative for the Kolbs.

If the 4 cylinder weighs only 15 pounds more than the 3 cylinder engine, I would think that the 4 cylinder would be better even for the Firestar. A lot more power and a lot less vibration for only 15 pounds seems like a real bargain to me. Mike -------- "NO FEAR" - If you have no fear you did not go as fast as you could have !!!

I know soon as is starts the flow ejects anything in the exhaust but is there a chance it may have got into the cylinders....2 strokes are funny ducks ! > If the dirt and stuff did not come out when you blew air through the exhaust and handled it, pulling on the rope would not have been enough to break the dirt loose and suck it in. Once the engine starts it is a different story. A two stroke engine has very strong pressure pulses in the exhaust that could very well suck stuff back in when running. There is a good chance stuff got sucked in once the engine was started. I would clean that exhaust out with gasoline or something to dissolve any oil built up, then with soap and high pressure water that would dissolve any last bit of dirt that might be in there. -------- "NO FEAR" - If you have no fear you did not go as fast as you could have !!!

Said another way, if the issue is the coverage of the two blades, in the current config, with one descending and one ascending causing a turbulent cavitation zone then counter-rotating blades would smooth that zone providing thrust in the zone where they cross. Some two strokes can be set to run either way, but must be supported by the manufacturer since there can be many gotchas that could cause troublenot readily apparent to the us pilots. Hirth engines tend to be robust, straight forward designs, so if any two-stroke will run the other way, I would expect a Hirth to. The final issue is the belt drive; the belt AND sprockets must be able to transmit the HP going the other way. Again I would check with your engine vendor. Naturally you will need to somehow swap/reconfigure the blades the make thrust the other way. I suspect you might be able to solve this interesting issue, please keep us posted whatever you decide. Your efforts have made for some of the more interesting posts I have seen in awhile, thanks. Jim Clayton California Mark-3X, 912ULS.....Building www.quantumwrench.com/Kolb.htm -------------------------------- -------------------------------- Food for thought..... Many years ago when I was young lad, I rode a small 2-stroke motorcycle with point ignition. Not knowing much mechanically, I messed with the points and got the timing way out of kilter. The engine would sometimes run backwards! So, maybe you could adjust the timing on one of the two engines so it would turn in the opposite direction. Maybe this would help the props develop more thrust. Just a weird idea, possibly good for a few laughs.

Mike Geez, about 4 years ago I checked out the 3 cyl. to go on my FS II & determined it was just too heavy. The 4 cyl. must run close to 150+ lbs. Besides the weight, at somewhere around 70 hp, youd hacw to beef up the cage.
