Increased fuel capacity
My header tank is 6.5, main tank 16.5 and the removable tank behind the pilot is 9 gallons. So, 32 total. Range is 800+ miles.
Sam
I'm curious if anyone has made modifications to their Q2s to increase fuel capacity. If so how did you go about it? How did it effect your CG?

I’ve seen Sam’s removable tank and dream of a similar setup. My header is 5 gallons and my main is 15 gallons.

I just watched your epoxy wipe video give minutes ago. It was your fuel cap blog, combined with an earlier conversation with another owner that made me ask.

There is a larger main tank pre fab that was available. I have one if you want pics or dimensions.

It’s basically the same tank by shape just larger. I think it nets to about 20 gallons.

The light one is prefab from CDC. See pic of label. The dark one is made and cut per-plans. Penmanship’s never been my strong point.
The arc matches for both tanks. Just the height and lengths are larger. I’ll do the best I can for max measurements.
Measuring the max arc length possible from the back of the tank around to the bottom lip at the front is 34 inches. The strait line distance from back lip to front lip is 24 inches. For reference the vertical section of the front wall is 8 1/2 inches.
Those are max lengths you could cut down from there.
Those lengths on the per plans are 30 1/4, 22 and 6.

I built a 13.5 gallon header and have 14.5 in the main. my CG range with all load configurations is in the allowable envelope. I like having more capacity in the header. All fuel is usable.

I have a 15 gal. Main, 5 gal. Header and a 6.5 gal. quick disconnect Aux tank that installs behind the pax seat contoured to fit in that space. Tank has a separate recirculating fuel pump that pumps directly into the header. I burn
it off first which gets me back in the middle of cg when at 1320 lbs. gross.
I’ve found its enough for me cause I like to stop for bladder and food breaks every 3-4 hours. I only install it for long cross country trips. Been in 26 states. Pictures in the files section under “Logistics Engineering”. Very
clean and light weight.
Header tank was designed to sit on pax side only, (not stock config.) which frees up space for the com/nav radios, intercom and transponder stack.

I built a 5-gal removable tank that is suspended below the wing. Attaches to fuselage on both sides. Gravity feeds to main tank. Jerry

Ryan,
mine isn't flying yet, still a project. My header tank was designed by a late Boeing engineer, Q1 and Q2 dealer-builder. The top of which doesn't extend forward toward the firewall. He did this for ease of build and maintenance. The sides of the header are not vertical, but teardrop shaped, for less unusable fuel. I don't know the capacity.
I built my main tank with a taller forward wall like some others, necessitating removal of the sandwich for a small area for elevator torque tube clearance. I estimate from other's similar design at 16-1/2 to 17 gallons. I made my consoles wet, following layup build like the other tanks. I installed a one inch PVC tube in each console (wiring and tubing for side consoles and aileron torque tube for the center console), floxed to the console top and extending a half inch beyond the seatback bulkhead and the side console forward ends, floxed on each side of the bulkheads. For the center console, a dry bay was made, with the torque tube phenolic being the barrier at the top and a foam sandwich panel angling forward to the fuel tank top. A piece of larger tube section was fabricated to join the aft side of the phenolic to increase the dimensional area for the joystick to torque tube bolt. I floxed versatube pieces in the bottom areas for fuel flow to the main tank and in the top forward ends for vents. I believe I also installed some intake screens, I'd have to check my pictures. I had to make a tunnel at the bottom of the center console for the seat belt attach points. Measuring water before installing the tops, each side holds one gallon and the center two gallons. I figured its on the fuel tank and using the same materials and techniques and at CG, will give me another hour at 4 gph cruise. Also, in climbout, the fuel in the consoles will move aft, the seatback area full for slightly aft CG for better climb performance. The main with header should give me about 25 usable gallons.
Was planning on making a fed dummy (person shaped) ferry tank of 25 usable gallons, that the lap/ shoulder belts on the passenger side would hold down. It would look like a torso with lap, which would extend forward to the front of the main tank. Again, this location normally holds a person, so a good location for the CG.
All together, this would give me about 50 usable gallons - ten hours at 5 gph if I find I ever need this kind of range.

Awesome to finally see one of the prefab tanks!! I've only ever gathered the little bit of information in QAC Newsletter #15:
NUMBER: Q2BT35
DATE: 26 January, 1982
Q2 and Quickie prefabricated fuel tank; This fuel tank is manufactured with the forward face about 3.5” higher than what is shown in the basic plans. This fact will allow more fuel capacity, if desired. Be sure to check first pilot and passenger legroom, particularly if you are tall. It may also be necessary to build a tunnel for the pitch control arm. The builder can, of course, use the plan provided template to reduce the fuel tank height to the standard figure.
I imagine the warnings above would still apply today?

I have a nice collection of kit to build. Very excited. What I don’t currently have is time. So I should have your signature as well.

My fuel tank is a pre-fab and I kept as much as possible to keep as much fuel as possible. That results in the valley to accommodate the elevator push tubes, as can be seen in this very old photo. As I mentioned, it holds 16.5 gallons.

A common theme around here….The panels get younger and the pilots get older 😊

Ryan,
Sam has a schematic of his aux. fuel system in his photos folder, in case that's helpful. I'm sure he can explain more:

So I finally went out and measured. It seem I already have the larger tank. Kind of stoked. I really have to say i have had some pleasant surprises with this aircraft as far as it seems the previous owner(s) wanted all the nice to haves. I really need to stop being lazy and get it patched up and flying.
