MPX Easy Star is a very nice plane on 3S lipo but you must be careful with the throttle, if not the brushed motor does not last long. You will also need a lipo pack of about 2,500 mAh yo balance her properly. Other planes are the Model Tech Fledgling, its larger but really good to fly. Needs only a 3S set up with some motor that can handle a 13x8 prop and you can use a 3,000+ mAh pack on this also. You will have good duration.
