Yes, gentlemen!
Even though I'm studying Electronics engineering...I like the last part of it...engines...nothin g compares the screaming of a methanol burner!! and the oily touch that you get in your skin....I love breaking in an engine...sometimes...when its difficult to fly by any reason...I just have to start an engine, you may say..to keep it alive...and I like to clean them...flip the prop, disassemble to the minimum piece and put it back together...as someone said, there are so many engines to buy, but not enough money for buying!!

AH...and what about not having to recharge batteries...just fill the tank and go...
