have done good for flow matching but that doesn't mean the carb/spider combination will deliver the same mixture to each cylinder required for them to work efficiently together. I flew a Cessna 150 that when leaned to a stumble then richened to "smooth" burned no less than SEVEN gallons per hour. That was very poor mixture distribution. I am not sure of the racers using the MA3 that is just my recollection. I also don't think Steve Whittman used a different carb on his Buttercup that he reported he ran at 4K. Best of luck with all your endeavors. Ted. -----Original Message-----

T-Tail-less Flight
Jon Finley <finley@...>
Hi all,
My Q2 has both a reflexor and a T-tail. I have always felt that these two devices are redundant and therefore the T-tail only represents extra drag (assuming the reflexor has "enough" throw to the job by itself). I have been successful at really goofing up the trim configuration of my plane using both devices (t-tail nose up - reflexor nose down, etc...). So, before my flying this weekend I took the T-tail "wings" off (leaving the torque tube that goes through the vertical fin in place). My impression?? Well, my reflexor had more than enough throw to do the job (get the tail down for landing and up for cruise). I suspected that possibly it would not (have enough throw) as it only throws the ailerons about 1/8" down and 1/4" up. I cannot quantify what I felt but it was definitely the first flight that I was able to set the trim and not touch the stick for a LONG time. The plane sort of slowly climbed and descended within a 150' range. I was cruising at 4500' and it varied between 4650' and 4500'. I did use my arms (move them forward for nose down and back for nose up) a few times. I think the plane may have been a bit more stable without the T-tail. Please don't take this as gospel as it is only an impression and there are lots of factors including the fact that I was flying in glass smooth air and I haven't had that luxury for awhile.

T tail
ARTHUR BOYD <warreen@...>
My kit Q2 ,GU and T tail is fixed ( not adjustable) which was built for
racing in the biplane class which requires a tail. has any body have any experience or details about its flying characteristic, also could it be made if nessary with a flap top and bottom to act as trim. Arthur Boyd |

LaCrosse, WI Q Lunch
Jon Finley <finley@...>
Hi All,
Paul Fisher, Kevin (sorry, didn't catch the last name) & son Jeff, and I all met for lunch today at LaCrosse, WI. I took a picture to prove it and have uploaded it to the Q-List files section (LaCrosse2000s.JPG). It was an absolutely beautiful day to fly. Visibility was unlimited, temp was about 25 degrees (didn't write it down so don't remember exactly), and sssmmmoooottthhhhhh as glass!! VERY NICE FLYING! I was a bit cold in my heaterless and drafty bird but it was worth it! Jon Finley N54JF Quickie - Volkswagen 1835cc N90MG Q2 - Subaru EA-81 DDT Apple Valley, Minnesota |

Re: 0-200 Carbs
Somebody get in touch with Mark. He is a highly technical individual.
Light years ahead of me on the subject. He is getting great fuel burn (wasn't it 4 gals/ hr?) There was some speculation that Klaus Savier was trying to come up with a fuel injected 0200. Don't know if it was true but Mark has already done it. Better atomization and more even fuel burn and temps across the cylinders. Don't know what kind of intake spider he was using but I believe it was some kind of automotive application on the EFI.

Re: 0-200 Carbs spider
The Ives Hive <iveshive@...>
The spyder on mine was very rough from the sand casting. I was told that
cleaning it up helps tremoendously. I used a 120 grit flap wheel on my dremel and got the inside looking like glass. The man that flowed my cylinders has an opinion that flowing the spyder is not the way to go. He says that when you open up the area in the spyder for the flow match that the larger opening will slow done the flow. It doesn't make any sense to me ! Ted says the F1 guys do it with good results. A Daytona race guy also says that flowing the spyder is probably the most important thing to do - and the only way to insure proper balanced flow to the balnced cylinders Any other thoughts on this . Does anybody know who can do this? Tom Ives |

I am interested in the aspects of tuning the 0-200 spider. Looking at the part, it's obvious that it was not designed for a high performance engine, 1940's John Deere would be more like it. I have no doubt that the fuel distribution for this engine is quite poor. Do you have any information about changes or improvements to the spider? Is there a Formula one site that might address this?

Re: 0-200 Carbs
Tom,
One of the Dragon Fly guys is running a GPU Continental with an Electronic fuel injection that he built. I believe it is Mark Snowden...maybe? Looked very interesting and he was really sharp at explaining the system. Very impressive. Anyone else in the group have a look at his set up?

Re: 0-200 Carbs
The Ives Hive <iveshive@...>
Ted,
I did not have the intake elbows or the spyder flowed - Mistake? - I was told that outside the cylinder ( elbows, tubes, and spyder ) was not as critical - as most of the bang (for the buck ) was IN the cylinders (Trying to do the poor man,s conversion) and that the cost of the extra flowing compared to the gain was not worth it .I was told that concentration on the carb (The amount of flow that can come to the cylinders) would be a better place to spend money. But this one man,s opinion didn,t have anyhing to offer on the present or alternative carbs. But from what your saying -The Ma-3SPA is quite adequate in flow ( 4 x 131 = 524cfm,s) and puts out all that the cylinders can digest ? Do you disagree with above advise? Tom Ives |
