Well let me be the first to say I am not knocking the engine... what I am saying is that their marketing numbers are BS. They give you a false impression of performance... stock it doesnt compare to the numbers.

Now go spend another $80 on the engine for the pipe setup and its a whole differenent engine.

However that being said we are now up to $475 for a 25 cc engine and quite frankly I would rather spend another 100 for a 60cc engine and fly a bigger plane. $475 in engine alone for a 72" plane is a waste of money if you ask me.
