    RE: New - Katana S30e by Sebart - Looks Awesome

    Hey Mike, My servos are HS65's all round. The plane is only a 3s setup and was not flying too fast, it was just the gap needing to be sealed. Yes the prop is a xoar 14x7 wood prop, they are slightly more efficient than an apc.
    Cheers,
    Sam

    RE: New - Katana S30e by Sebart - Looks Awesome

    Hello,
    I have a Sebart Katana 30E aeroplane.
    It has the recommended Hacker A30-14L motor
    It has an APC 14 x 7E propellor
    I am using a 3S 11.1 volt 25C 2300mAh battery.
    The problem is that the motor is drawing 45.8 amps = 515 Watts of power
    Hacker say that the motor should draw maximum 35 amps for only 15 seconds
    This is also too much for the recommended 40 amp speed controller.
    Is the recommended propeller size wrong?
    The lipo seems to go flat quite quickly and the plane will prop hang but there's not much power to climb vertically.
    Thanks for any replies,
    rcflyers

    Do you know if your motor is the original version or the 'V2'. It's reasonably easy to tell, the V2 has a cooling fan built into theend of the motor. See photo here: http://www.aero-model.com/Hacker-Brushless-A30-14L.aspx

    The original type motor just has a plain end plate, like the one pictured here: http://www.marionvillemodels.com/rc-...K-A30-14L.html

    The V2 motor is rated for 50 Amps so should be safe in your application. The ESC might be on it's limit but if well cooled might be ok. What brand is the ESC? You may want to try a Xoar (or JXF) 14x7 wood prop, rumour is they pull a few less ampsthan the APC. I'm running the A30-14L V2 with the Xoar prop in a Precision Aerobatics Ultimate AMR. I'm getting2 - 2.2Kg of static thrust which on a 1.1Kg model gives great vertical performance. What does your Katana weigh? If it's much over 1.5Kg then the vertical is probably not going to be stellar, going to four cells and a smaller prop would certainly pep it up(without increasing amps).

    If flying with lots of open throttle you will be limited to maybe 5 minutes flying, i can get over 8 minutes of general sports flying out of my AMR with the same motor and same 3 cell2200 battery.

    Hope this is of some help
    Steve
