Hi gang,



I ordered the Extended Tank Range (2 x 23 gal US)  threw CanZaq Aviation (Canada), and I would say that I am more than happy   by the QUALITY of the tanks (10/10). The thank had no waves deformation and they are accurate. Even with my best local welder, I cant find a better Job. 



First good surprise, the plan specified 0.025 material in 6061-T6, and the thanks were in 0.032. Secondo, the tank are coming with all fittings from the tank to the firewall. I don't ordered the complete kit, only the tank with fitting. It come with tube vent, fuel quality cap, fuel quality selector, electronic sensor and a gascolator, 1 inch. cork, fuel line and so on. The inventory is completed, no missing pieces, conform to plan.



I will post photography later on the photo archive forum. 



Conclusion : Its over my expectations and It's dont pay to do it yourself.



Tanks to Zenith and Mark Townson from CanZaq Aviation.

I find it odd that they would have .025 spec'd in the plans and then make the tanks in .032. In a recent conversation with Tim, he told me they used .025 for tank construction.

Glad to hear you are happy with the product. .032 would definitely make for a stronger tank, and easier weld operation.

Still planning to build my own, since I bought .025 on Tim's recommendation that is what I'll use.

May be It's because they are bigger than standard tanks they made it in 0.032.

Chris, could you please take some photographs of the tanks? I'm particularly interested in the sides and back. Thanks.

If you don't care to post them here you can e-mail them directly to me. I think you have my e-mail address already.

Hey Chris, one more question, please. Is the top/nose/bottom and back skin

one continuous sheet of aluminum? That would make three pieces total for

shell construction.

Yes the  bottom, up and back sides is a continuous form, one piece. You have also left and right side, this mean 3 pieces to weld. If you plan to do the tanks in 0.025, I suggest you an inside ribs with holes in bottom and top to let the gaz freely circulates. This inside rib will give more rigidness to the tank.



See you.



Christian

Hey Chris,

 First off thanks for the posting the pics. They were great. I was wondering what type of fuel sending probes you were going to use. I want to install a flat panel like the Advanced flight systems one, and I'm not sure if it needs a specific type of fuel sending unit. I think the ones you have in your pictures are float type, not the capacitance type, right? Just wondering if you have done any research as to whether other types of sender units can be installed in these tanks. 

Thanks,

Try the following link for just about everything you ever wanted to know about capacitive fuel senders. These guys make them right here in Michigan. I'll be using them in my aircraft.

very educational website.

You'll want to find out for sure what your avionics needs before you order the probes. But you can order mounting flanges separately, that's what I have done, so I can procede with tank construction without having to decide on avionics installation.

Thanks Craig,

  Very neat site. It'll take me awhile to got through all the info they have there though. Lot of good stuff! I really like the mini power panel too.

Chris, I have yet another question. From the photographs, I see that the fuel float assy. is not installed. I'm guessing that the small welded panel on the side is the base for installing the the float assy?

Hi Craig,



Your right, this small plate is for attaching the fuel sensor with 3/16 metal screw x 5/8 of an inch (24 tread). The hole was done with a 1 5/8 Dewalt hole drill cut off remover.  This plate is done with a square piece (3 x 3 inches) with a 0.125 piece of 6061-T6 welded to the tank skin. See photographies attached.

Additional info: 



Rectification it is not exactly metal screw that should  be used, but metal bolt with cross head for tightening with a screw driver tool. You should do hole with tread with a left hand tap tool.
