iron eagle wrong in hp on those engines. closer to 5hp.

For the guy wanting to convert your .91 size DF to EF should go visit the EDF section in here or even better yet goto RC groups forum under edf Jets.

Edpare give us a ling to your plane or give us the dimensions of it. Dont get hung up on the 36ep thing.

also you cant compare direct watts of a glow engine to an electric power.

That 1.5 hp in the 46 is way off. closer to 1.1 hp in that engine. that 46 will not spin a 12x6 at 12,000.

900 watts is close to most 40-55 size engines. the electric motors turn bigger props so they make more thrust.
also it will take more KV than 650 to spin that 12x6 at 12,000 rpm. most electric motors are around 80%
