    Has anyone done a comparison and figured out the lightest (and good) smoke pump available?

    How about different tank material to keep the tank light?

    My Pitts has an Art Scholl system which uses a Holley pump. I have used the Sureflo pumps in the past with good service. I always wanted to use air pressure, no pump at all. The Yaks are well suited for this as they have an onboard compressor.

    Build a tank from fiberglass or aluminium. The roto-cast plastic ones are anchors!
    If I remember I pop some pics of the one I am putting in the Eagle.

    The CJ Systems smoke pumps with the brushless motors are the lightest we have used. Worked great in Red Bull Air Races but I'm not sure if they are building them anymore.

    Aviat sells the Holley pumps for the S-2B and S-2C. They just don't have the Holley sticker on them.
    They charge $150 to remove the decal.

    I am searching my paperwork. Will post when and if found. I may be able to get a picture of the pump.

    Here shots of the tank- Filler is back end of 'Mag-lite' type flashlight (idea stolen from Death Trap). It can easily be used a hose barb if I decide to add remote fill.
    I prefabbed panels on a sheet of plate glass & tabbed them together. Rounded corners used PVC pipe as mold (mould if you are fro m UK)

    Very nice! This looks like fiberglass? How much does it weigh? Capacity?

    Hi Nate, I have received very good reviews of the density of smoke I produce with my O-320. I used Marvin Homsley's nozzles which I think make the system really work well. Also, I inject the smoke oil into the #3&4 two exhaust stacks before they converge. First convergence is 1&3 and 2&4... then those combine into a single. That smoke oil has a lot of time to spend in the exhaust which ensures it gets vaporized. I do not get smoke oil all over the belly of my plane. Flow rate is about 3/4 Gal/Min.
