Here's a 3hp model plane motor. It weighs 750g all up. http://www.hobbyking.com/hobbyking/store/__9969__Turnigy_26HP_S_26cc_Gas_Engine_3_0HP.html http://www.hobbyking.com/hobbyking/store/__9969__Turnigy_26H... And here's 3hp electric motor (550g), although that's probably an unfair comparison. http://www.hobbyking.com/hobbyking/store/__18177__Turnigy_Aerodrive_SK3_5065_320kv_Brushless_Outrunner_Motor.html http://www.hobbyking.com/hobbyking/store/__18177__Turnigy_Ae...

The horsepower ratings of engines in the hobby world are optimistic at best. I have personal experience with some RC airplane engines and a dyno, and frankly I don't understand how the manufacturers can keep advertising the numbers that they do.

  I have personal experience with RC electric motors and dynos and they are correct.

  Source on that? Never heard anyone claim the numbers on these motors were fake before.

I believe those have thermal problems, use more fuel and have a shorter lifespan?
