    Kinda bad if you get motors then have to wait 2 more month for the jackets to arrive.
    Do you mean Leopard sells jackets? If thats the case I didnt know.

    We have to have the 56mm motors in our possession before we can design and test jackets. It takes time.

    I hope to have more 40mm jackets in a couple of weeks.

      water jackets are fairley easy to make.....just find a piece of pvc pipe with an outside diameter thats about 1/8" bigger than the outside diameter of the motor......wrap carbon fiber cloth around around the pvc pipe about 4 or 5 times and clear epoxy it.......wrap the pvc pipe with seran wrap first..then just take the finish product to plumbing supply house and get two o-rings to match

        Leopard Vs NEU

        Hello


        I have a Leopard LB5692 1090KV, it´s a 2Y winding.
        The first thing i made was opening it up, in order to see the interior.......
        The quality seems very good,just like craftmanship.
        All is made by CNC machines,wich is normal in chinese countries....i already visited a factory that had more then 50 CNC lathes working day and night with automatic feeders.....


        The stator laminations are 0,2mm, the cross section of the cooper cable is considerable,the same as mine 1527 1.5D.
        The rotor seems well balanced, and is wrap around carbon fiber.
        But all go to this.

        Cooper cable quality
        Magneth quality
        Design quality

        This is what changes efficiency from 80 to 95%

        I still couldn´t test it because it doesn´t work with mine schultze 32.200WK

                Schulze ESC's have a hard time with some motors...

                The 1080Kv on 8S will be nice, 32,000 rpm unloaded. Good for my 40" mono.

                      I've tried 445, it worked well, on 5000mah I get about 2 minutes runtime at WOT in a mono. So maybe 447 will be ok as well. Hydro should load the prop less and with 445 the motor comes in cold anyway, so extra load should be ok.
