Default Ultra Micro P-51 - Reverse Polarity - What would happen

Theoretically speaking, what would happen if the battery was connected to a Parkzone Ultra Micro P-51?

I bought one used, and I'm trying to determine why something bad happened, and this is one of the possibilities.

Thanks!

Sorry to re register, but I somehow got instabanned as a spammer with that one post with no warning. I'm sure it's a simple mistake, but I was hoping to get an answer so I know what was the source of the problem so that I can get this fixed when I go to the hobby shop tomorrow. I've sent a message already asking what I did wrong to get permabanned, but I don't know how long that will take.

UPDATE: Mods were quick to fix the situation. As I thought, all just a misunderstanding.


Basically, I plugged my battery in after a shop re did the plug the battery connects to (it's a different plug than stock), and the motor fired up all of a sudden. I had been messing with the settings on my transmitter, so I thought I screwed up the trim or something. But then it stopped, and the battery I was still holding onto got hot. In my attempt to disconnect it, I ended up pulling the wires out which had melted all of the insulation. There was also a small hole burned into the left side of the fuselage.

My thoughts are either the shop put the connector back in the wrong way when they re did it, causing a reverse polarity connection when I plugged it in, or the wiring inside the fuselage was bad and a short circuit occured.

I appreciate any help! Thanks!

Honestly, that problem sounds like something that should go right back to the shop that did the work.

If they screwed up, you cant prove anything if you 'fix' it. Melting anything in a model is not good. Having to yank wires on a 'hot' anything is also not good.

We could guess and speculate all day, but you are better off looking the retailer in the eye and asking them to demonstrate how it is supposed to work.

Normally...... any shop that does anything to a model, will demonstrate it functioning before you leave. If they did not, hopefully you will have some recourse.

Thanks. Yeah, just depending on what actually happened changes who I should hold accountable. If it's bad wiring on the inside, I would go to the guy who sold me the plane since I made no changes to the internal wiring. Otherwise it would be the shop if they redid the connector the wrong way.

We'll see tomorrow I guess. Thanks!

Turned out to be the shops fault. They checked and confirmed the plug was on wrong. At least I got a new one to set things right. So I'm good to go.
