Re: Fuel Sight Tube Broke- pics included

Jay, How do you know if your header tank fuel pump quits and your no longer refilling the header tank? Also instead of the 1/4" output on the lines I put in a restrictor. This way if the line does break, you'd get a much smaller volume of fuel coming out. Mike Dwyer YouTube Videos: https://www.youtube.com/user/FlyMeAirplane/playlists Q200 Website: http://goo.gl/V8IrJF

Yes, those are a yearly replacement item. Looks like yours might be 5+ years old! When they are no longer clear, your on borrowed time! Same thing with the header tank overflow tubing. Mike Dwyer YouTube Videos: https://www.youtube.com/user/FlyMeAirplane/playlists Q200 Website: http://goo.gl/V8IrJF
Brittle little tubes these are. I’m starting the new panel build and was emptying the header tank. I barely touched the sight gauge so I could watch the fuel quantity decreased. It cracked immediately and fuel started to spray. As I panicked and yelled, “tell my story….” to anyone that could of heard me, I tried to put my thumb over it and it broke into more pieces. Plenty of fuel emptied into the middle and pilot seat before I could rig up the hose and water container to collect it. Fun.

Re: Fuel Sight Tube Broke- pics included
Hi Corbin,
I have a conductance gauge, so it is electronic and shows up on my EFIS, as does my main. It is pretty accurate, but it does depend slightly on relative humidity (we have none where I live, but you can have lots where you live). Also, level varies by 30-40% at high AOA’s. At one time I considered using a float gauge in the header but changed my mind. I have a back-up float gauge in the main, which I like, but it was easy to install.
There are other options for your header, but I think most people will coach you keep the sight gauge, since you have only 5 gallons, and I assume you mostly leave it full all the time. I have a 13.6 gallon header, so it is more like a normal tank, so I can run a couple hours without filling from the main.
Cheers, Jay

Jay - I was thinking of getting rid of it and only using the fuel indicator on the G3X display. But then wondered if I would trust it. Do you have a standard fuel gauge for yours or are you "glass" and use that fuel indicator in the display?

Re: Q1 Fuselage comes up
Terry Crouch
The depression is done before glassing the inside. The insert is installed before glassing the outside. I did not put a screen over that depression per plans. Instead I put a finger strainer ( screen that is in a cylinder shape) over the depression so the water can find the low spot (quick drain) and there is still a screen over the fuel pickup tube.

Re: Rigging
Chris Walterson
Mike------------ On mine because on each side of the canard and wing, the layup is done in one big step and technically the "spar" is built in my build was inspected when I had bare foam and all the jigs in place. I built the wing and canard at the same time so I had all the foam and carbon fiber cut so the inspector could see. I also explained what I was doing and the process.
After that I was good the final. If you check with MDRA you will see what the previous builder did. You definitely need at least one inspection prior to paint. Take care----------- Chris -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Re: Rigging
Mike Steinsland
Hey Chris did you have to have two inspections,one before you covered the wings with primer and then another after you glassed them on but before priming the connection? Canopy masking idea's a good one. Have to remember that.

Re: Rigging
Chris Walterson
Mike------------- I don't know if I mentioned before, but I find it better to do all the filling ,sanding and priming on the wing and canard before attaching. Leave enough unfinished to glass in place. I also watched a few videos and saw where the lower bellcrank is about 6 inches. Then, I watched a photo video of a Q built in 1985 and it had a bellcrank about 3 inches.
I will wait around to see if there are other opinions, but , I think I am going to stick with how I have it. I am finishing the inside of the canopy, and one thing to be aware of is to mask the outside about 1/4 inch in from the edge. Then prime and paint. When you remove the protective cover from the inside you will see your paint line through the inside plexiglass. You can mask the inside to this paint line and then paint. I notice most cockpits are a different colour from the outside so this way you do not see the two different colours around the canopy line.

Re: Rigging
Mike Steinsland
Please keep me posted I m planning to do all the rigging for the ailerons later because I'm going to put off attaching the wing until I have as much done as possible. My space is a bit restricted and walking around 2 wings might be awkward. I'll just file away your findings for later

Re: Rigging
Chris Walterson
Mike--------- you're right. Sometimes my licdexia takes over. Even so, I have the two top bellcrank at center of tube to bolt hole
2.5 inches and the bottom bellcranks center bolt hole to center bolt hole 4.5 inches. This will give me 40 degrees of total travel. If the bottom bellcrank is only 2.9 inches , you won't have any travel. Maybe they mean 2.9 from center of tube to bolt hole. That makes more sense. I'll see if I can find some other pictures on line.----------- Chris -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Re: Rigging
Mike Steinsland
Hi Chris Here's what I have from my plans Unless I'm reading this wrong the QCSA3 appears to be the bottom bellcrank that needs the 2.9 " spacing. Photos from plans attached As I said I haven't installed mine yet so I'm not sure how the geometry is.Let me know if you find something different from what I understand

Re: Rigging

Mike---------- The measurement change was for the upper bellcrank. 2.9 inches. There may have been one for the lower one, but my plans weren't as complete as they could be and I didn't find anything. The 4.5 measurement seems to work well, but I'll wait for the other guys to chime in before I commit. Take care------ Chris

Hey Chris I haven't done my ailerons yet and I'm sitting on my couch away from my plans and news letters but was the measurement change for the aileron bellcrank for the upper one or the lower?
