How much fuel needed for a Super Tigre 60 for the pattern.

How much fuel needed for a Super Tigre 60 for the pattern.
Hi Joe,
It is all over the board, but I would say the "average" is between 6 and 7 oz. All depends on who set it up, venturi size, nitro, etc., as far as I can tell. ;D
I am *hoping* my Big Jim 60 will get the pattern in on 6 1/2 oz. !!

Yes me to, I ordered a 6.5 and a 7 looks like the 7 will fit but will be close. Thanks for the info.

Joe,
I have been using the latter Tiger 60 with muffler bosses and concave heads and standard venturi.
Lines are 66 feet center of fuse to center of handle. Zinger 13/5 prop letoff RPM about 8200. Fuel is
Sig Champion 10% nitro 50/50 blend. Plane is about 700 squares at 47.2 ounces. With these specs
its taking a titch less than 6 oz of fuel. This info includes the use of a BRU-LINE green air cleaner.
I hope this information will help you. (PE**)

Joe,
I forgot to mention that I run MUFFLER PRESSURE also. HB~>

Thanks for the info, mine is using right at 5.75 for the pattern with five laps or so at the end with a Tom Lay engine in a Streaga on 60ft eye to eye lines running 5.2 laps with a 13x6 Top Flight Power Point breaking at the top of munevers on 22 percent fuel.

Joe,
A little less than 6oz. Bowman ST60 in a Magnum.

One thing that stands out here in Ted's post is the Bru-Line green airfilter.These work very well, but keep in mind that the green , fine foam filters tend to choke the venturi down just a bit. Not to say that they rob a bunch of power or anything, but they can affect the fuel draw. They make a black filter element that is much more corse, and may not affct the fuel draw or consumtion rate.
Getting enough fuel for the pattern is onme thing, getting enough fuel for the pattern in ALL flying conditions is, I think critical. Colder air requires more fuel. I saw several planes go in at around the clover leaf one yearat our contest hear in St.Louis. We had fairly warm weather on Saturday, and everybody was practicing with the fuel load that they were used to all summer. We had a cold front go through that night, and the next morning dawned 25 degrees or more colder. Several guys ran out of fuel before the end of the pattern in their practice flight the next morning, and a couple of planes were lost as a result. That's were practice and taking notes of conditions, or at least have a good memory and be familiar with what your airplane needs. I like to have at least an ounce more than I need in warm weather, if the fuselage will allow it.
Type at you later,

PS to add; And Ted's model is a VERY nice model. One of the lightest ST.60 powered airplanes you''l find. A nice but not gaudy finish, very business like airplane.

I will have to try and make the “Ice O Lated” contest to see Ted’s airplane, he usually builds light, strong and straight.
I have to add that Ted took me under his wing when I was 13 and just starting to fly CL. He was a great mentor, it did not matter that I was a lot younger than him at the time, he still took the time to teach me all he knew about the sport. I learned the pattern with his help, I learned how to build light, straight and how to start an engine with one flip of the prop from Ted. I am glad to see he is back into the sport, maybe someday I will get back into flying. Ted had become and remains a good friend, I just wish that I had more time………….

Glad you see you have found your way here.

I used near 8oz, but then, we were flying at 3000 feet with "beer can" sized venturis.

Hello Bob, I had heard that you were back into the sport, Ted gave me this link, great job man! I think I still have the first video that you took at my shop in the basement, pretty cool. Good luck with the this concept, I think it will be a great success!
