    Artr - twin mean machine 2

    SOLD

    I have my twin Mean Machine 2 for sale, The inside Transom and Hull have been reinforced, Sponsons have been Blueprinted with West Marine - Marine RX and all edges are sharp and flat.
    It could use a new paint job, some chips and marks in the paint but the hull is solid.
    It will come RTR except for Radio and batteries.

    This boat was built to Race in the "P" classes (Offshore, Cat-Sprint)
    This boat is designed for a 4S2P - 65c - 5000mah battery setup.
    For Offshore class (over 4 minute run time) the 90mm EDF Tacon 3674 2Y/4Pole 1700kv motors with Left and Right hand water jackets from HRC were picked because of there higher efficiency and Watt ratings. I did however upgrade the bearings with Boca Ceramic Hybrids. With two motors the Amp draw has to be kept below 65A each. With this setup I was able to run at 55MPH and turn like on rails.

    For "P" Cat-Sprint (6 lap Oval) I have a pair of LBP 3674 3D/4 Pole 2200kv Motors also with Left and Right hand water jackets from HRC
    With this setup it runs 60MPH on rails.

    With this hull I have found that running the props outbound it preformed a lot better for racing. It is more stable at high speed in the turns.
    I also had to extend the rudder so that the leading edge was behind the props.
    This was done because this hull does NOT have a overhang at the rear.
    This hull is only 29 1/2" long, so it runs the same as a 33" or 34" hull that has a overhang. It also has a wider stance (5 5/8" between the sponsons) then other hulls which gives it more stability at high speed in the turns.

    Here is what is included;
    Mean Machine 2 Hull
    2 -Speed Master Stinger Struts

            Brian

            It runs on a 4S2P setup
            The two ESC's are wired so that they each see the 4S2P.
            Batteries that I use were two 4S - 56C-130C - 5000mah

            Speeds were 55mph to 60mph with the 1700KV motors - ABC props
            and 60mph to 65mph with the 2200 motors - ABC props

            Here is a little Video of it running last winter in Florida, this was with the 1700kv motors.

              Would you sell without the tacon motors but include everything else?

                The Tacon motors with the Boca Ceramic Hybrid Motor Bearings were what this setup was designed around, to get the best runtime. For running in the Offshore class You need 4 1/2 min. runtime
                With these motors and the Octura X442 props, Run time was 5 minutes, with very good speed( 50mph)
                When I changed to the ABC 1615 - 17's my speed went up (55mph) and my runtime dropped to 4 1/2 min. which made this setup perfect for the Offshore class.

                If you are not racing this is your best setup with a long runtime with a good speed.

                If you just want the 2200Kv motors and everything else, I will change the motors for you and change the timing on the ESC's to match the motors.

                $575 USD + shipping from NY state

                    Ray that is the reason that I chose that motor, It has the highest ratting for a 3674 motor, and the Boca Ceramic Bearings made it even better.

                      I just realized that they don't sell the Tacon EDF (Electric Duct Fan) motors any more.
                      They have replaced them with the Leopard motors.

                      As you can see in the pictures these are the original Orange Tacon EDF motors.
                      I replaced the bearings with the Boca Ceramic Hybrids to make them even better seeing that I was going to use this boat for racing.

                      These motors only have about 20 runs on them.
                      The 2200 Leopard motors only have 8 runs on them.
