T45 Goshawk Problem on maiden flight.

What battery were you using? What is its capacity and discharge (C) rating?

I had a problem as soon as I took off, I felt like I had no control on my power. I was never able to settle the aircraft by trimming it. It would like go fast and slow at its own will. I was out of control all the time. Battery was 99% charged, flew for 4 min and landed with a boiling hot battery at 0%. I was able to landed by pure luck. Any hints as to what’s going on, or what to do to correct the problem???
thanks

Does it do the same thing on the ground?
