    ESC beeping problem

    I got the tiny trainer speed build kit last week. I got everything from the FT starter bundle (So I'm using the Power Pack A, a Tattu 2 cell battery, and the Spektrum DXe Transmitter). Every time I move the throttle a little the ESC beeps at me and the motor jitters a bit. I believe that I...

    Help with ESCs and FC

    So I recently started buidling my first quad, and have done everything mechanical except attach my receiver. My problem is that my motors do not show any activity, and that I can't flash my Flight Controller. I don't know if the first problem is the result of the second, but I am stumped. I have...

    Constantly beeping Motor

    I have made my first scratch build for RC planes. When I connect the ESC to the battery and motor, the motor constantly beeps. Right now, nothing is connected to the receiver. I looked this up and it says I connected it wrong, or my minimum TX throttle is too low. First of all, this happens even...

    Solved ESC starts up but won't spin up motor on input signal

    Hey folks, I recently started reactivating a quad build that I had laying around for 2+ years (thought I mention that so that people don't get confused with the pretty outdated hardware) and didn't touch since. Back when I left it one of the ESCs was broken, so when I picked it up again I...

    Are ESCs Dangerous?

    Hello Everyone, Humor my electronics ignorance, but I have been wondering about this for a while now. I've read (and heard) that 'Volts hurt, Amps kill.' If you have a low enough amperage, you can have volts to arcing all over the place without any real danger. I've read that anything above 100...

    KK2 board throttle calibration starts programming ESCs instead?!

    Hi, just want to share an issue I'm having, hope somebody knows how to solve it. I was just calibrating my ESCs throttle to get them in sync on a quad powered by a KK2, but instead of the two beeps at full throttle and then one beep at idle, after the usual ''1+4 button, power up, wait for...
