I HAD ONE WITH A 120 OS IN IT AND WHAT A GREAT FLYING AIRPLANE. AS YOU READ ,HAD. THE FLIGHT BATTERY CRAPED OUT 2 MIN. INTO MY FIRST FLIGHT AND IT WENT IN HARD INTO THE WOODS BY OUR FIELD. ENGINE AND RECIVER WERE THE ONLY THING I COULD RECOVER FROM THE CRASH. THE PLANE TOOK OFF LIKE A TRAINER AND WAS SO STABLE IN FLIGHT IT ONLY NEED 2 CLICKS OF RIGHT TRIM AND IT WAS HANDS OFF. THE BATTERY WAS NEW AND NEVER IN A AIRCRAFT. I WAS PISSED! SO I CAME HOME AND ORDERED THE SAME PLANE AND THIS IS ALMOST READY FOR ITS FIRST FLIGHT, I HOPE I HAVE BETTER LUCK. GOOD LUCK WITH YOURS.
