person wanting imfo on Q's, Dfly's, Q1's or any other project is to go into the files section of that group and as Jim said type the question in and walla, you will get answers. Remember these are experimental so research and learn all you wish to then build it how you want. What works for some is not the only and best way to go, If you can't follow rules like that maybe you should be looking into a certified type and leave the repairs to someone qualified.

Re: Fuel Vent Line
David J. Gall
Ya know, Bob, I thought about that too. Here's the way I see it: the lowest
toggle quoted messageShow quoted text
pressure the carb can pull on the fuel line will be at high rpm with the throttle closed. The highest ram pressure will be at max airspeed. Dive with the throttle closed to purge the vent line. Not a good plan. So there you are on climbout and the engine sags due to fuel starvation. The rpm drops off, you push the throttle open, and the airspeed decays. What good will it do to know that you would be able to clear the vent line at Vne in a power-off dive if the powerlines ahead and every nerve fiber in your body are screaming that you'd better add power and get the nose up? I already know that the correct response to a power loss in climb is to push the nose down to retain flying speed and that is already contrary to my instincts. Please don't make me learn to hope for power restoration by diving at the ground and chopping the throttle, too! I don't care if the theory says there "ought to be" some combination of airspeed and throttle setting (closed!!?) and rpm that will clear that slug of splashed fuel from the vent line, I won't have time to diagnose that THAT particular problem is, indeed, THE problem. I would much prefer a fool-proof system that works in an intuitive way that I can count on time and again to be reliable, predictable, and repeatable. ("Gee, would zero-gee help the ram pressure to purge the vent line," Robin queried Batman as the Bat-plane plummeted perilously earthward.) If my fuel tank vent line does NOT require me to perform acrobatics in order to restore proper engine operation then I'm more likely to have time to apply carb heat and squeeze the manual fuel pump bulb -- oh, yeah, we took that out of the system last month, didn't we.... :) Not to make too much light of the situation, your Pacer wing tank collapse was caused by gravity feed PLUS pressure differential, working together, and there's a good bit of head pressure from a Pacer's high wings to the low-mounted carb. And there are other factors to consider. Even if the fuel flow from that tank to the engine were shut off, simple contraction of the fuel with decreasing temperature could have collapsed that tank. Top off an already almost full tank in the morning, leave it setting in the sun all day, then the mud dauber builds his nest in the fuel vent in the afternoon... And you may never even have needed to start the engine! As opposed to your Pacer's gravity feed PLUS pressure differential, purging a slug of fuel from the QAC fuel tank vent requires determining the difference between the action of gravity and the pressure differential, working against each other, in other words, gravity MINUS pressure differential. In fact, the "gravity" portion of the equation might just be zero, or even a little bit negative, if the slug of fuel in the vent line is taller than the height of the fuel level in the header tank is above the carb inlet. So we'd be left with just the pressure differential to move fuel through several feet of small diameter (0.22") fuel line at approximately six gallons per hour, or 0.85 ft/sec. Given that ram pressure at 60 mph is 1.5 inches of water, and assuming that the carb is in the high pressure ram recovery region of the cowl, the pressure difference available to drive the fuel flow in climb might be quite small indeed. Certainly not equivalent to the head pressure of approximately 14 inches of fuel (10 inches of water) that the header tank normally gives.... I think you get my point by now. Thanks for helping me to have to think through this problem. Now I know that there's another thing I want to do differently on my airplane than what the plans call for.... :) David J. Gall

Re: Fuel Vent Line
David J. Gall
Mike,
toggle quoted messageShow quoted text
I'm not advocating this installation at all: I'm trying to get people to see the difficulties of it and to opt for the simpler vent going out the top of the fuselage. We're all so used to seeing a fuel tank vent under the wing of the Cessna we rent that we may not be putting much thought into the "simple" act of "copying" that vent. Indeed, that vent is very different from the QAC vent. And you're right, the transition from large diameter to small in my suggestion does pose a potential problem. Let me jump to the conclusion regarding your suggestion to use the filler pipe as a catch tank. In essence, the Q2/200 fuel tank(s) are actually (in a fluids sense) just one tank. The header tank is connected to the main tank via the 5/8" standpipe down the middle, through which the "two" tanks communicate both fuel and air. The advent of the header tank is that it provides a reliable head pressure to feed the carb. The header tank is kept full by the fuel transfer pump. You can think of this transfer pump as a part of a "live" tank as opposed to a passive tank. In a passive tank like on a Cessna, when the tank is nearly empty the head pressure is still good because the bottom of the tank is above the carb. In the Q2/200, the "bottom" of the tank is artificially moved up to the level of the bottom of the header tank, because as the main tank empties we transfer the fuel to the header. This "live" transfer makes the tank seem to the carb (in a fluids sense) to be mounted higher in the airframe. Consider the act of filling the tank: If you fill the main tank until the filler neck is full, doesn't the fuel also rise within the 5/8" standpipe to the same level as in the filler neck? Now, mind you, I haven't got operational experience with a Q2, but it seems to me that you either have to run the electric fuel pump during refueling in order to fill the header tank, or else the header tank fills when the fuel level reaches the top of the 5/8" standpipe. Either way, when the header tank is full so is the 5/8 stand pipe and so is the filler pipe. Therefore, ANY vent connected to this tank system anywhere had better be above the fuel level or it will have fuel in it. Ergo, your proposed vent from the filler pipe would need to be just as long (in the vertical dimension) as the existing vent from the header tank. Moreover, the filler pipe vent would be just as susceptible to fuel getting into it as the existing vent line is. Keep up the good work, David J. Gall

for the quick answers. some of us come around sooner or later. i left this website in disgust a few years ago. it was my strong desire a love for this airplane that brought me back with my tail between my knees. since then a world of knowledge has opened up to me that was there all the time! the ultimate coolness of this plane attracts anyone who is a fan of aviation and the cost to own and operate is also atractive. it's my feeling that if the Q 2 didn't have any handling issues they'd be fetching the same price as a lancair or glassair! i can understand the frustration of you oldtimers getting sick of the same old questions, but , as long as this website is around, new guy's will surely ask them and they'll get angry when flamed. this little fraternity is easy to get into, ego aside, but, we're pilots! so eating a little crow is difficult for us. a new guy is not going to ask the right questions, he's going to ask the same questions as all of us did when we saw this amazing airplane for the first time. we want one and we want it now!!!! the truth is if we want a good one we have to build it! then the right questions come to fruition. there are some oldtimers on this site that have been here for years and still haven't flown yet. i don't know about you,but when i get home from work i look foward to checking out what's been said on the site. new or old at least there's activity. questions or comments this is a pretty cool thing for all of us! if your new and your reading this,these guys do have your best interest at heart. you don't neccessarily have to ask the right questions, just hang around long enough and you'll get it! the Q is the most beautiful and exicting airplane around. to own one is a privilidge that most will never know. mines not flying yet ,but, it's the center of my universe. even know, the hanger at my airport is always buzzing with guys just wanting to be close to its construction! wherever there's a Q there will certainly be a crowd! Q's in one form or another are still around,but , for how long? this website is the only glue holding these planes togrther.... patience is key, or Q depending how you look at it.

Re: Diesel Quickie
jeffs912ex@...
Hi Bruce,
Hey, look what I found in my "waiting to be sent folder" better late than never. The fellow who did the engine installations doesn't even know all the answers you request. Rather than give you incorrect info I'll stick with just what I remember, I wasn't taking notes. I'll bet someone did though . The first diesel flown on this airframe was a 4 cylinder. The fuel burn was not known by him, but he did say it would run on just about anything including peanut oil. A very compact six cylinder is on the firewall now and is rated well over 100 hp. Test pilot Dave M. is scheduled for the honor of test flight, soon. I'm sure you will see and hear more about this plane, it is a beautiful example of an experimental aircraft. I think a better test bed for this engine is a Q 200 at least you could punch it. That reminds me, good job Sam. Those lawn darts have a bit of an advantage though. Thought I saw you at Doug's hot dog roast, na maybe not. Jeff Sell Q-200 kit
