LOOKS GOOD, MANUYAL SHOWS OS 70II WHICH IS 20.3 OZ SAME AS THE SAITO 100. WITH THAT 15X4WIDE APC IT WILL BE A GREAT COMBO. I KNOW SOME OF YOU ARE SKEPTICAL ABOUT USING THE 100, BUT WITH THE 4 PITCH PROP I CAN TELL YOU FROM EXPERIENCE THAT IT WILL NOT FLY FAST AT ALL, BUT HAVE THE HANGING AND VERTICAL ABLITY THAT IS FANTASTIC. THAT ENGINE AND PROP GIVES APPROX. 11LBS OF STATIC THRUST. THIS WAS CALCULATED ON A TEST STAND ARRANGEMENT BY A LOCAL FLYER. IF THE PLANE COMES OUT AT 5 1/2 POUNDS, THEN 11LBS THRUST IS EXCELLENT FOR 3D FLYING. STAY TUNED!
