Giant P-51 Mustang destroyed on take off


A very expensive electric conversion destroyed within seconds of take off. Even the most experienced pilots make small mistakes which can have disastrous consequences.

Hangar 9 P-51 Mustang converted to electric power.

So a fairly heavy model to start with as it was designed for the rigours of IC power. Then add a weighty battery pack .......

If you want electric power, buy, (or preferably build), a model designed specifically for electric power only, they're lighter and have a lower stall speed.

I'm not so sure. I doesn't look like it ever stalled to me. He pulled it into a tight turn and too much elevator drove it into a spin. It was flying all the way to the ground. Some opposite aileron would have pulled it out.

From the video's Youtube site comments --

'CRASH ! Giant scale P-51 Mustang DESTROYED on maiden flight
This was a fairly horrific crash of a Hangar 9 P-51 Mustang converted to electric power with very little surviving the impact. The pilot confirmed that the cause was a stall that sadly he did not have enough altitude to recover from. This things happen to the most experienced RC pilots but this was an especially expensive and unique model so sad to see it happen.

I think Scott is correct!
I would also add, the turn was not balanced to start with. This led to increased pilot work load and increased demand for pilot attention and skill.
The model appeared to be flying plenty fast enough and was not climbing when it dropped a wing.
Pilot error, simple as that, and very common. Shaky over control with the elevator and no rudder compensation is what I am seeing here.
Sorry to see another fine scale model go in.
Builder/pilots of large scale models do tend to be overly nervous on maiden flights.
Ask me how I know?.......................
