RE: Nitro models pusher Bobcat?
No it's not the same motor.
It's a Tower Pro ( sold as the BP2915D at BP Hobbies ).
This motor has a max capacity of about 500 watts, and is supposed to be the equivalent of a .30 sized glow engine.
Since yours is far more powerful, I would assume that it needs an even bigger prop to be able to draw more power.
