Was it nitro, electric or turbine?

Electric is pretty obvious and turbine has on board start equipment that can be started with the flick of a switch.

The majority of nitro helis use a hand held electric starter. I would guess that some of the larger models may have been converted to be on board start. This would only be practical in big models where the weight would be less of a factor. I can't see any real benefit of it apart from looking cool.
