RE: Need help!
The set up will work as long as you put the right size prop on the motor.
For a given battery voltage the motor will always try and run at a particular speed, the bigger the prop the more work it has to do and hence the bigger the currentit will draw from the battery (and through the ESC)
I am not familiar with the motor you have so I can't say what size will be right, maybe someone else can help here. Most common way to connect the battery to the ESC is with what is called Deans connectors.
I do have a couple of electrics but I'm nore into glow/gas powered planes, so I don't claim to be an electrics expert. I can however confirm that connecting an ESC to a battery the wrong way is bad news!
