The MB-6B [16 minutes flight time]
Well, its finally here, after 8 months in the making, lots of changes, dozens of different configurations, huge setbacks like the one during the Orlando Funfly, the latest revision model, the MB-6B has successfully gone through the most gruesome flight testing program I've ever done to any of my helicopters before.
The newest MB-6B offers excellent flight characteristics which allow it to excel at a wide range of maneuvers, from the relaxing hover and slow cruising around the backyard to the to heart pounding aerobatics at the flying field. All this with average flight times of around 16 minutes, so chances are you'll get bored before the batteries are done.
There are substantial changes between the MB-6A and the MB-6B. Some of those changes are a quad tail rotor and upgraded electronics, amongst others. I also tweaked the SK-360 settings further and for the 1st time ever it uses my own tail gyro settings (I was using Bert Kammerer's 3D settings for the tail gyro since the numeral MB-6 was originally meant to become a TREX500 for 3D, not a scale 450!).
Tail rotor reliability factor has been drastically improved with the revised tail setup. Most likely a 100% reliability factor as no failures ever happened during the exhaustive and gruesome testing in crosswinds (what ruined the tail of the MB-6A) and several complete packs doing hard piros left and right. Since I didn't want any ugly surprises like the MB-6A fiasco, this time I've flight tested it to destruction.
Video is uploaded now, and its 15:43 flight time between spool up and landing. The video has no camera cuts, heli never goes out of the camera view... (beware dial-up, video is 134 Mb in size. Youtube won't let me host it b/c its well beyond their 10 minute limit)
