How many watt's ?

[BrianG]

Like Sammus said, the torque/HP curve is totally different. Nitro engines may develop 2HP, but usually towards the upper end of their rpm range, and even then, this band is not very wide. Probably closer to 0.25HP or less at low rpm. And nitro engine torque is also low at low rpm, while BL motors have tons from 0rpm. This is what gives BL the diff ripping power and is so addicting. Different animals altogether.
