Hi I'm new, but I've been lurking for a short time. I recently crashed my P2 and repaired it. Replacing one esc,one motor, the shell, and the receiver. Now when I slide the battery into the compartment and power it on it turns off within 2 seconds. I don't get any lights from the LEDs. But like I said it powers on out of the P2. Pre repair i could power it on still with three LEDs yellow and one red. Any suggestions as to what to look at? What other info might you need?
