    Backup RX pack

    After having a brownout and a not so good landing(at least it didn't crash or fly off into the sunset), I am thinking of adding a 5 cell Nicad as a backup to the ESC for my T-34. Is there anything that I need to do to make it work with the ESC? I dont know if the ESC is failing, or if the motor is overheating it and causing the BEC voltage to drop off even though the Lipo has a full charge. Right now a 5 cell 2000 mah is a whole lot less expensive than a new ESC and Motor. I am going to see if I can repair the motor which appears to have a bent shaft, but wont know for sure until I press it out since it is press fit into the bell.

    RE: Backup RX pack

    Well, you might consider what I did.
    Disable the internal BEC, and connect an external one, capable of about 5A at 5-6V, instead of the internal 2A BEC.
    I don't know what speed control you are using. Some of the E-Flite speed controls have a switch that enables/disables the internal BEC.
    Disable on those that I have is switch closed, or the leads to the switch soldered together.

    RE: Backup RX pack

    I decided to swap the electric out for glow power, less expensive than replacing the ESC and motor.  I replaced the shaft, but it still vibrates.  I think the plane will be more badass with a 4 stroke popping along than the anemic whine of the electric motor.   That and Im the only one flying electric, so when the other guys fly, I can't hear the plane and wind up dead sticking it.
