Brian, I love your Avitar. Yes it finally started to snow here in Alberta. Not like you guy's in the east have it though.
Keeping with the theme of our thread. Here is the tanks I installed into my used Sukhoi this fall. 2 X 710ml in series. The original owner had a single 1.5L only secured by Velcro. Used by many, but I just sleep better when anchored well.

My setup using secraft cap and fittings.

Nice tray! Is that a Secraft product?

Unfortunatley not. Moulded it myself. Cut a female mould from tooling board on the CNC machine and then vacuum formed it. The indents stop the bottles moving back and forth.

Awesome work!

Have you guys ever considered aluminum caps like this one? They use them on wine bottles and other stuff. They probably wouldn't crack like plastic. I'm going to use this one.

Let us know how it works. I prefer to just use a PSP and forget it.

I already bought this one so I need the cap.

Mine will use the aluminum cap, Viton, and a Walbro felt clunk. So it's not exactly like the pic. I'm just using the stopper and the fittings in the pic. And a Fiji 1 liter bottle of course.

I've been using water bottles as fuel tanks for about five years without any major problems, I can tell you they work exactly as a Dubro Tank, what I like most is weight, cost and ease of see thru. But i want to share something that happenned in my RC club about three years ago, In my club there is a member who is probably 70 plus years and is one of the nicest persons that I know in the hobby, he is always making us stories of how the hobby was back in the days and specially all the hard work that takes to build a plane from scratch, no wonder he is not up to date with the new technology or recent inventions, well one day he brang a Piper Cub that he had been sitting for a while and when he start to fill the plane with gas we noticed a big fuel leak and discovered that then fuel tank had split, a friend of mine had a step drill and a cordless drill and we told him not to worry, inmediately we looked at the garbage can and found a 16oz Fiji Bottle and made him a tank in about 10 minutes. He looked very surprised and told us that from now on he will not spend a dime on a fuel tank. That day he gave the Piper about five 15 minutes flights without any problems. I beleive that we just help a friend, but if it wasn't for the invention of water bottles tanks that day he cannot flew the piper Cub.

Back in the days my grandparents used to make juice from different kinds of berries. They used old wine bottles for storing the juice. The aluminium caps were not very good and leaked easily. They tend to expand when repeatedly tightened until they won't be tight any more.

Just my 2¢.

Looks like a successful setup to me. Where did you get that stopper?

Thanks that's good to know. I wonder if tightening just once will not cause that. I think this stopper that I'm using is not really depending heavily on the cap so the plastic one will be fine. All I need is something to keep the stopper from backing out which it may never do. The cap won't ever get fuel on it. I'm probably over thinking this.

Thanks guys for all the great info, will be switching over

OK, I've been a Dubro tank kinda of guy since, umm, a very long time ago

I have looked and looked for a 3/4 to a 1 gal water bottle for a while now with no sucess, since my 50% tank requirement is between 80-100 OZ's and now I am ready to give in and try a dual tank setup to meet my needs. PSP products are to be used.

So, on the secondary tank, how does that plumb into the primary tank and which tank do I attach the filler to?

thanks, BV
