Can one of you kind chaps please give me a detailed description of how you plumb your turbine tanks.

The system I am using is 2 large tanks in series and a hopper/header tank.

How do you connect them all up? i.e

How many tubes per tank and what does each one do?
Where do the tubes go inside the tanks?
What tube thickness?

Detailed help will be very much appreciated

Each main tank is going to have two lines and the hopper will have three. I use 3/16 brass with the next size up in 1/4'' lengths to make a retaining nipple on the ends so the tubing cannot slide off. Each main tank will be set up as normal with a clunk and a vent that reaches the top of the tank to allow full capacity of the tank to be used. The hopper will have a center pickup or filter clunk that goes to the pump, a fill line and a feed line from the mains, these two lines should be short in the tank so that you again get full capacity. going from the hopper back this is the way it should work. the feed line of the hopper will go to the clunk of one main tank and the vent of that tank will go to the clunk of the second main tank and its vent will go overboard. I left a small amount of brass hanging out to hook up an overflow tank. I used tygon tubing and safety wired all connections just to be sure they stay put. Hope this helps. Here is a few pics of the stingray tanks that should clear everything up for you.

you can kind of see the lines on the header tank here.

Well Strato. That is fantastic.

Thank you very much for your incredibly detailed description.

Strato,

You say you use 3/16 tube. That is very thick bore. Is there any reason you use that????

I've got a wren 54. Do I need to think about that or is standard tank parts sufficient??

I use it to keep the internal resistance down in the tubing so the tanks do not swell during fueling/defueling, also it makes it easier for the pump to draw fuel through all of that tubing. I am running a RAM 500X. My ducted fans have a hard time sucking through standard tubing so I would go with the big stuff, there is probably a chance of a flameout if you use the small tubing, also get yourself some aluminum fuel tank caps, they will not split like the plastic ones.

Cheers once again Chris.

The standard tank caps utilize narrow tubing. I will drill them out to take the thicker tubing.

I've not seen Aluminium tank caps. Who does them, and have they got a website????

Hi Vease

Instead of the hopper tank use a BVM UAT from motors & rotors
or jetline that will stop all air bubbles to the turbine
Would not dare to fly without one anymore also make sure pipe
lengths are the same to the uat to ensure both tanks drain equally

sullivan products and BVM makes them
