Need some help gents:
Running a stock electric Losi XXXSCT.
Days are nicer so I pulled it out for a shakedown.

Electronics are stock Dynamite 3300, and stock 45A ESC.

Here's the skinny -

Plugged in a freshly charged battery and nothing.

Swapped batteries.

Power to the esc and motor.

Drop 'er on the ground, throttle up, and works like normal. 10 seconds later, it acts as if the battery is dead - slows down and no throttle.

Get off the throttle, neutral, then back on the throttle, and it takes off.

Then it slows down a little - turn the truck around, hit the throttle, and it goes, but not the way it should.

Bring it in, wait a second, hit the gas, and it takes off like it should. Then slows down.

Multiple batteries have been used for testing. All batteries test with correct voltage to each cell, and show that they are charged.

Any thoughts?

Thanks in advance!

The first thing to try is recalibrating the ESC.

Instructions for a similar esc here...

Check the sensor wire at both the motor and the esc.

Wires are all good.

Went through the esc reset process and no change.

Here's a short video of what it's currently doing

So it only has the problem going forward and not reverse?

What about half throttle from stop?

^^^Correct sir - there seems to be no issues in reverse

Half throttle and seems to be a little better, but then does the same thing...
