Speed Testing

I tested the speed of my 700E the other day. But there were some flaws in my method, so the readings were more than likely inaccurate. The good news is that they are probably slower than the actual speed because the heli was flying further away from the camera than the boxes. This means that it could have flown further than 7m. The next test I want to do is the climbing speed. I have an altimeter which can plot alititude vs time, this will allow me to work out the speed by dividing the distance by time.
