Electronics problems with my super cub

    Hi,
    I took my super cub (hobbyzone) out yesterday to fly and the bullet connector came off on the plane side. I'm was not that surprised as it was very difficult to solder them due to the shortness of the wire.

    I planned on putting new cable onto it completely and soldering on the bullet connecors before soldering onto the planes board.

    Today, seeing as it's a nice day here I decided to myself "feck it I want to fly" so I pulled the plug off the the other cable and the two plugs from the battery....I connected them up (raw) and nothing! There was no response at all from the remote control.

    After a minute the motor started spinning all by itself without any input from me. I tried moving the controls around abit but it was completely non-responsive and even when I turned off the remote control the motor still continued to spin.

    I'm thinking the circuit board electronics must be frigged. What do you think?

    Here's a pic of me showing the circuit board and stripped connectors.....

    How I connected the battery...

    The servos are prorietary hobbzone afaik....

    Some ppl with other electronics problems have gone out and spent over $200 on new electronics. I don't want to do this.

    I'm sorry to tell you this but this does not surprise me. I understand you don't want to spend. But stuff that works well costs. Below that price is disposable toys.

    Those circuit board receiver-cum-speed controllers don't last anybody very long as I can see. In the past I have personally had at least 25 "hopefuls" ask me if I could fix their broken circuit board.
    So it may be broken. BUT ... it may be OK.
    You see you had a friction electrical contact with those twisted wires. That would cause the electronics to react in unpredictible ways.
    So IT COULD BE that maybe if you solder on the plugs correctly everything will work again. Try it first.

    Hmmm .. thinking that the soldering (or lack of it) in the wires could be the problem. Likely is. My post above edited. :)

    Oh great I'll give re-soldering a go.
