The smoke tanks are about exactly what I was envisioning. Though the more I think about the W&B, I realize it would be quite limiting in terms of eating up your baggage capacity.
Your tanks adding 30 gal additional capacity at only 4 lbs is impressive. What are they made of? I couldn't imagine aluminum tanks being that light. I like the thought of your auxiliary tanks all feeding into one main, or how the HW Aviation aux tanks feed into the mains. Considering many engine-out issues are related to fuel delivery, if an issue with delivery from the aux tanks were to ever occur, I'd think it would be likely to be discovered when you still have several hours of fuel left, rather than a potentially really bad time. I realize Im getting a bit ahead of myself. I'm doing my empennage build at Synergy in February so even thought I haven't started building yet, I just ordered my QB fuselage & wings so that the project doesn't stall out waiting for them after finishing the empennage. So I'm trying to be proactive and am researching things I need to think about ordering for the wings & fuselage. thanks for the pointers. |
Mine are so light because I wet 3 bays of each outboard leading edge. Only added weight are the fittings, fuel line, and some scrap aluminum to cover the lightening holes in the nose ribs. Would be a bit more effort on a quick build, but it's doable with a modified technique.

Has someone already tried to "simply" build bigger standard tanks?
So enlarging the tanks by two or three ribs spanwise? |

Hi Malte,
some guys have extended their tanks all the way to the tips. But doing any change to the original design (in Germany) will probably not excite your counselor and the LBA. That?s why I made a removable tank for the rear baggage area for my -8. Even then the LBA required quite some calculations and fulfilling of "building codes". |

Can you give some info on the 2 psi switch you used. Mfg, source, etc. I just ordered the tanks last night at 6:30. Hotel Whiskey answered within the hour. HW is under new ownership and apparently have solved the previous communication problems. Off to a great start. |
Stewart Warner Hobbs Pressure Switch 1 PSI Normally Open 2 Terminal - p/n 78628. I did not remove the main tanks for the installation. So I did not use the Bung fitting provided by HW. Instead I used a bulkhead flare that I sealed on both sides with proseal in the top rear corner of the main tank. I also cut a 4" X 6" panel opening in the wing to perform the installation and to inspect and access the pumps etc. It was not an easy task to work in that confined space, but it can be done with lots of patience.

As this is an interested crowd, I am selling the 5-way valve I showed in post 14 of this thread. Please check the classifieds...
