    Electronics protection

    Yesterday I was bashing my Tornado S30 in a ditch next to my house and it bumped into the curb (not too hard). Directly after that, the electronics ceased to function, and the thing was nailed at full power. I was forced to watch helplessly as my buggy recovered from the shock and bounced onto the street, throttle gunned. The next thing I knew, it had shifted and smashed, full speed, into a stone wall. It flipped over and revved so fast it shredded my tires before I could get at the flywheel with a stick. Damn, another $50 in repairs.

    My batteries are duct-taped in, and when I switched the car off and on again the electronics were fine. I suppose I could just buy a throttle return spring (and I will), but I would prefer that this issue be fixed. What part of the electronics do I have to protect with foam to keep this from happnening again? Is it the switch getting knocked back to off? Any help here?

    RE: Electronics protection

    UPDATE:
    I thought it might be the switch soooo....
    I cut some wires, relocated the battery plugs to the outside, and bypassed the switch. I took it out (everything seemed normal), ran it a bit, but when I went off a 1.5 foot jump the electronics died again. I checked my juryrigged plugs (they were still in and working) So I plugged and unplugged them a couple times. Nothing happened. I tapped the electronics box kind of hard, and lo-and-behold, working again. Is it the receiver or the batterys? And what can I do to stop this from happening again?

    cswtornado,

    It could be the receiver or the battery holder, when jarred does the electronics completely shut off with no power?

    Thanks,

    It seems like it, but I don't know, how do you tell?

    RE: Electronics protection

    cswtornado,

    If the power was cut off then nothing would work on the vehicle and you could turn the servos by hand, meaning the on/off switch could broke or you lost a connection. But if you still had power the servo/s would work or at least be holding in one position, meaning you probably lost signal.

    Thanks,

    RE: Electronics protection

    Ok, then I completely lost power.
    I replaced the batteries just a few days ago, bypassed the switch, the stuff is all fine UNTIL it gets jolted. Would a fail safe work for this problem? I just ordered one plus a new receiver.

    RE: Electronics protection

    cswtornado,

    Well if you are losing power completely them it's most likely going to be a bad connection somewhere causing the receiver to get no power. I would even get another battery holder and make sure that isn't defective. if the receiver has no power a failsafe will not work, because the failsafe needs power to turn the servo. But you could use the failsafe along with a throttle return spring so when you lose signal, the failsafe will kick on. But if you loose power the return spring will pull the carb closed.

    Thanks,

    RE: Electronics protection

    cswtornado,

    You could try connecting one end of the spring to the throttle linkage, and the other end to like the shock tower. Something like that should work.

    Thanks,
