I'm rebuilding a lightly crashed Avation Diamond. I'm currently building my fuel tanks and I'm copying the originals just a few oz bigger.

So im try to build the smoke tank but I'm trying to decide between building a 40oz or 50oz smoke tank.

So my question how big of a smoke tank would you want for a 160-210 size turbine? Thanks

There is no relation between the size of the smoke tank and the size of the turbine. It really depends on how much room you have for a smoke tank. I have a 120 turbine with a 48oz smoke tank. Also I want thick smoke so I have the smoke turned up as fast as it will run. Also running two sticks

Go with the 50oz Mike. Bob-o's right about the size of the engine not really being a factor.

Go with as big as you can fit in. You will burn through it fast. If you dont want to carry the weight all the time just dont fill it all the way up.

The general rule is 10 oz per minute for smoke.

That might be true for older pumps like the Skywriter. Modern HV pumps like the Powerbox Jet smoke pump can burn through 20oz per minute at full power. The amount of oil burnt also depends on the diameter of the injector tubes and if you use one or two tubes.

That's why I like skywriters, they smoke great, use less smoke and last FOREVER. I have a 10 y/o skywriter that has 100's of gallons through it and works like a champ.

And it's 1/2 the price of the powerbox!

Depending on your set up (number, size, type and placement of injector tubes, brand of pump, voltage, diameter of tubing, etc), it's likely you may not need to run at full power/volume. At some point, more smoke oil doesn't necessarily translate to more smoke. I like to start by putting the smoke pump on a slider and experiment to find what volume gives the most bang for the buck.

On my new Natrix, I'm running just one of Dreamworks "Super Stick" injectors with a JetCat smoke pump. The set up puts out great smoke (Super Dri oil) but after about 70% throw the smoke does not noticeably increase. I now have it set to 70% at full throw and manage to get longer burns per/flight. I haven't timed it but I guess I'm getting 4 minutes or so of smoke with about 50oz of oil.
