RC Pro Dies on Impact

[Dan RC]

Hello, I have a Narly Brushless made by RC Pro. I have only used it a few times. On impact, even a very small one it looses all power - shuts off. I have tried 2 batteries and it does it with both. They are securely installed. No loose wires or anything obvious. Can someone give me their thoughts?

Thanks.

Sounds like a loose wire somewhere maybe. By chance is your ESC LED flashing any number of times? If it is ESC related, it may be flashing an error code to help you diagnose the problem. I'm not familiar with that ESC, so check your manual. If that is no help, drive it without the lid on. When it stops, wiggle the wires where they plug in or go into any components and see if you get life back into it.

Try unplugging your servo and ESC from the receiver. Put a little dab of dielectric grease on the pins in the receiver and plug them back in. Pay close attention to which way the plugs are, and which channel they are on. Because the plugs will go in either way. The signal wire (white or yellow typically) is usually closest to the center of the receiver.

Sometimes, if a servo is going bad, the RC will not move. In these cases, you can test that by unplugging the servo and seeing if the throttle functions again. If it does, you likely have a bad servo.

Welcome to the site. If your esc and battery connector looks like the link, this is my suggestion. Plug it in then pull it back some. Then try it. If it works replace connectors. Fir some reason a little tension on the spring or contact did it.

I'm saying this because I had chargers that would only work like that. Also check for corrosion.

Thanks guys, corrosion isn't the issue, I checked it out yesterday and everything still looks new. Servo seems perfectly fine. I think it is esc or battery to esc related. I appreciate the help, I got them to use with my son and this not working has been frustrating. Thanks.

Hmmm, did the airbags deploy at all? ok, sorry couldn't help myself.

Does sound like a loose connection of some sort. I was thinking the same thing as @Chubaka. Maybe one of the connector's pins has a bad solder, and is breaking the connection when it gets a good jolt.

It's hard to say what that issue is. Could be battery, ESC, or electrical connection as the others have suggested. Unfortunately, this is the point in the hobby where you have to start replacing parts with known good parts, and eventually you'll figure it out. Start taking parts off the other one, one part at a time, and installing them in the malfunctioning one until you discover what the issue is.
