    Hovercraft from Kohls:

    Hi guys,

    Newbie here on this forum. I'm into R/C tanks 1/16 Hen Long.....

    Anyhow, my brother bought this hovercraft at Kohls over the christmas holiday and the center motor stopped working. I pulled the motor out and it turned out to be bad. I had another one exactly like it laying around and I soldered that one in. Put it back together and it works but not much air flow. I know the motor was fast, I tested it.... but when I tried the hovercraft out and it won't move with props blowing in the back. The motor doesn't seem to perform as well now that it's in the hovercraft. Here's a youtube of the exact one, but it's not my video. http://www.youtube.com/watch?v=AquiMfT1nIk

    It also had another problem, the circuit board. One compenent was right next to the plastic housing and it got hot and melted the plastic a bit. Wonder if that could also be part of it's problem?

    Anyone have one or know much about them?

    TIA,

    RE: Hovercraft from Kohls:

    the motor you put in may be the same size, but if it has less turns then it wont have the torque to spin the prop fast enough.
    or, the motor you put in has many more turns than the stock motor, so it doesnt spin fast enough.
    either way, to many or to few turns and it wont spin the prop fast enough.
    when it comes to anything with a prop, the motor specs have to work with the type of prop. props with higher pitch require greater torque to push the prop through the air.

    RE: Hovercraft from Kohls:

    We have played with several motors of this style in the toy grade subforum. Ask a mod to move this thread in there. Those guys have lots of experience with what you could use.

    RE: Hovercraft from Kohls:

    Makes sense......I believe I put the exact one back in there but could not swear to it, it looks identical to me. I had wondered if a mosfet was the real problem since one got hot and was too close to the hull and melted the plastic near it. The mosfets control the current flow and i'm just guessing as whether this one that got hot is now the problem and not the motor

    RE: Hovercraft from Kohls:

    it may be the same "size" motor, but have a different number of winds(the number of times wire is wrapped around) which effects the amount of torque and rmps at a given voltage.

    RE: Hovercraft from Kohls:

    I don't know too much about hovercrafts or prop engines, but could it possibly be different voltage requirements? Maybe the engine you're running in there is also causing the heating because the voltage is incorrect? Just a thought....[&:]

    RE: Hovercraft from Kohls:

    The windings could be different, I don't know....I'll try comparing the old motor with the new one. There is no number to be seen on the mosfet.
