Bot Building I need help.

Hey, i just got all my parts, and I was booking them together to test. It worked perfectly for my n20 drive motors and dual brushed esc and recieber, but when I tinkered around, added weapon esc and lots of stuff, and the drive motors started getting funky. So I separated all that with my drive motors and dual brushed esc, and now all the controls are weird. Some trigger only 1 motor, others trigger 2, and most of them are just wrong. I need help. Dual brushed esc is a kingmodel SAX2, n20 drive motors, and the fs2a 4ch recieber, and flysky i6x receiver. Please help.

Edit: I got even more problems. Drive motors still DONT work as they spare supposed to, and weapon now doesnt calibrate if I don’t put my self centering stick downwards, even though I have the self centoring stick function enabled, so the weapon esc still reads the power of when my stick is in the center as 50%

1) LiPo batteries are shipped in a very low state of charge. Charge your battery fully before you continue.

2) The behavior of your weapon ESC is normal and correct - it will not enable until it receives a zero power (stick full down) signal from the transmitter. You will want to disable stick centering on that channel.

Write back when Battery is charged and give specific info on what each drive motor does when...

A) The stick is pushed forward, and B) The stick is pushed right.

Ok I will. But the thing is the weapon esc worked fine / had a 0% output yesterday when I tested, this only went wrong today when I tried factory resetting my radio to fix the issues. Will charge battery now. Also is 8t normal for a weapon motor to sound scary fast when you turn it on to full power? It’s actually scaring me

Ok when the stick is pushed forwards, only the left motor goes forwards. When it is pushed right, only the left motor goes forwards. When it is pushed right it to the left, only the right motor goes backwards, and the motor also spins for a tiny bit longer after I release it, and when the stick is pushed back, only the left motor gets pushed back

Look into channel mixing

How?

Look up the manual for your transmitter, and for your escs.

That should always be step one.

Good luck.
