The supplied motor is enough power for vertical (in both directions) hovering and climbing, with a 3-cell pack. The PPS is definitely less efficient than a standard prop because of the lack of twist, though. Make sure you have your pitch curves set up right, because I KNOW that little motor has enoguh power to tear the PPS apart if it gets a chance to over-rev! [:@] Check your pitch servo and make sure it doesn't have any damaged gears before each flight, or you'll soon find out the hard way!
