OK, so I got Hubsan to fly while waiting for my H to come. I was flying in the house in a large open room. I had the prop guard on. I had a few minor crashes but one motor stopped working. I tried recalibrating with no luck. So, I ordered more motors and props. My question is what's a decent soldering iron and what kind of solder should I get to solder the motor leads to the board? It's a $30 drone and I just bought parts for $20. So, I kind of don't want to spend a fortune fixing it. Thanks!
