I love this classic plane because it has extreme great details all over which reminds me almost like a scale plastic model kits on showroom yet it flies!..which is why i bought this. Based on actual replica of Boeing-Stearman PT-17 this model is made from EPO foam and mixture of hard plastics parts for aesthetics looks. Runs on generic 3s 2200mah 35~40C lipo battery pack it could fly for about 8~12 minutes depending on flight styles. Under my control this stock factory plane has huge amount of thurst to weight ratio and i can feel it has enough vertical torque to enable aerobatic maneuver such as big loops, immelmans turn and minor barrel rolls above our club fields. The only challegging moments was trying to land this plane without having to dip the front nose and hit the prop which is a common issue even on real world classic plane of its era. Overall its one of the must have R/C plane for civilian style aircraft in any R/C hangar.
