Query: Looks Cool When It Flies, But...

Very durable plane. It has to be considering how many times it crashed. I have only had three flights for 30 - 45 seconds out of approximately 75 - 100 attempts. The rest of the time the plane nose dived as soon as I hand lunched it. It doesn't seem to have the power that everyone else claims it has. I have replaced the motor and gears with Megatech replacement parts. In addition, I made sure the battery is charged. However, the plane still doesn't want to fly.Finally, because the battery compartment cover never wanted to stay on, I lost it during one of the crashes. There were even a few times that it fell off before the plane crashed.All of this is very disappointing considering how much the plane costs.
