power 25 glow comparison

What would be the glow equivalent to the Eflite power 25's? I have a pair laying around and want to build something to put them in, so to go down the right path I need to know what size 2 stroke plane they would work on. I currently have a Hanger 9 Twin Otter running a pair of these, so have some idea how big a twin it can pull, but knowing the glow equal would be even better.

This is a reversal of the usual comparison... they are called Power 25 because they are considered the equivalent of a .25 glow motor!... for, I assume, a ".25-size" aircraft (whatever that might be)

Is that .25 2 stroke? Reason I ask is because one of these came out of a T-34 that needed a .52 4 stroke to fly it.

Most of the E-Flite motors are intended to run at a lower RPM than the average 2 cycle glow engine.
The 25 is somewhat of an exception due to three versions with different KV ratings.
If I remember correctly, the low KV version 25 is a 600W motor. That's about .8HP

Yes, 2 stroke

OK I have an idea what size twin warbird to build. Thanks.
