I am very close to completion on my Mountain Models Magpie. I'm dying to fly it today, but I am confused by some technical issue. I'm trying to connect the motor and battery to the ESC. I have to hook up these Dean's Ultra Plugs to get everything connected. I was hoping someone could be very specific with instructions to do this...I am brand new to flying. The intructions say: 1. Use a HOT soldering iron, with a 1/8" tip. 2. Put one piece of tubing onto each wire. 3. Do NOT plug together during soldering. 4. Strip wire 3/16" and pre-tin. 5. Pre-tin connector pins. 6. Solder as shown. 7. Slide tubing over solder joint and heat-shrink. I'd greatly appreciate any help...I don't even know what pre-tin means! Thanks!
