I would pretty much agree with Troy, although my tank runs dry after 9-10 minutes. Guess I must be a bit harder on the throttle! Coolpower 30 and a 16x12 prop, tank is a tettra 20oz.

Contrary to some reports, using the supplied foam clunk you can get through a whole tankful. If it gets really low it will hesitate briefly, as if to say - land me now! I certainly don't feel the need for a header tank.
