Well torque is a great way to measure to power of a given IC system and current draw is a great way to measure the power of a given e-system, but in the end, its the amount of thrust you produce at the prop.

An IC system produces its max HP at a RPM that is almost never used for flying. We usually run an IC system at about 80% of peak HP on the RPM scale. Thats because of the usable torque available for the prop is more efficient at that speed.

An e-system you can measure current draw but unless you know the efficiency of the of the motor and/or motor/gear box its hard to compare.

In both systems you can measure the RPM at the prop and then do some math to determine "ballpark" static thrust.

In my case I have:
1. hyperion 4035-14 with an apc 16X10 @ 8100 rpm ~ 12.1 lb static thrust
2. YS 110 spinning an apc 15x10 at 9000 rpm ~ 11.6 lb static thrust

These look very compatible but on the same plane fly "a bit" differently. The YS version will fly faster and initially look like it climbs vertically much faster from full speed in a straight line . Down line speeds are faster also. Transition from slow horizontal speeds to vertical maneuvers will look a little more sluggish. Conversely, the Hyperion version will fly slower and initially (compared to the YS) look as if its climbing slower but in a long enough vertical climb, will start to look like its out pulling the YS version. Down line speeds are slower and transitions from slow horizontal flight to vertical will look more powerful.

In the end, these two power systems are very close.
