The Sensei is everything you could want in an electric trainer, and more. Final assembly time is just a few minutes. The foam airframe is lightweight, durable and easy to repair. The stable high-wing design is ideal for learning to fly. A "drop door" on the underside of the fuselage lets you deploy a parachute or other creative payload from the 5th channel of your radio. And a brushless motor, ESC and servos are already in place. Go with the Rx-R (Receiver-Ready) version and you have the freedom to equip your Sensei with your choice of radio and battery. For the ultimate in convenience there's the RTF (Ready-To-Fly) with a 6-channel 2.4GHz radio and powerful LiPo battery preinstalled. Either way, you'll have an easy-flying trainer with traditional styling that you'll be proud to take to the flying field.br br Learn more about the Hobbico Flyzone Sensei EP Trainer Rx-R and RTF by visiting their product page at br Tactic TTX600 6-channel 2.4GHz Radio System (TACJ2600)br br Join Flyzone on Facebook at br Sensei EP Trainer RTFbr HCAA2535br Wingspan: 58 in (1475 mm)br Wing Area: 566 in² (36.5 dm²)br RTF Weight: 3.2 lb (1451 g)br Wing Loading: 13.3 ozft² (40.6 gdm²)br Length: 48 in (1220 mm)br br Sensei EP Trainer Rx-Rbr HCAA2536br Wingspan: 58 in (1475 mm)br Wing Area: 566 in² (36.5 dm²)br Rx-R Weight: 3.25-3.
