Descriptions: This is a brand new helicopter designed and developed by Ming Da Technology in Taiwan. Full CNC aluminum head and tail, bearing blocks, levers, everything possible is CNC aluminum. Very rigid well supported frames sporting a top mounting motor. Although this helicopter is a high end precision 3D machine intended to use a 6s 3300mAh battery you could run 2 x 6s in parallel with one battery in the tray and the other battery in the extra room in the frame for the ultimate longevity heli capable of flying 20 minutes or tame it down with a 5s big boy pack to make it a nice non 3D machine. The hovering while taking off is very stable but it will still satisfy the different flight characteristic of even the most demanding of pilots. The ultimate concept of the designer is to fulfill easy configuration, convenient maintenance, high stability, agile action, secure operation and all of these have been completely realized on this helicopter. The M-3D 500 is light, fast and extremely precise to sum it up very quickly. First to note is being cleverly constructed using many winning approaches seen on other designs. Next they didn't skimp anywhere on the CNC aluminum the quality of which is superb. The one piece frames are high grade 1.6mm fiberglass and chosen for weight they are extremely strong. The servo layout is as direct and symmetrical as possible housed in aluminum mounts. The battery tray is adjustable on tilt and position. The M-3D 500 spent a great amount of time being flown and developed by MD. They and their top pilots have engineered a very nice airframe. MD has engineered a very true running head which is very fast but the agility of this helicopter lies deeper, deeper then the direct servo to swash geometry. The M-3D is the perfect weight for the 500-515mm blades it swings. It feels really good with a 6s 3300 but could easily hold a 4000, maybe even 5000 if you didn't want to 3D. It uses standard size servos including the frame mounted tail servo. The adjustable battery tray making it extremely easy to utilize all types of 6s and possibly even 8s batteries. The gear ratio is 1:4:3 with a 159T main gear making for a wide range of motor options! The maximum pitch range is +/- 14 degrees with a high-class design of tunable action-ratio for programming the head. The ultimate concept of the designer is to fulfill “easy configuration, convenient maintenance, enough components, high stability, agile action, secure operation” and all of these have been completely realized on this helicopter.”   Features: Electric Power System Full CNC Main Rotor Head and Tail High Grade 1.6mm Fiberglass Side Frame High Quality 500mm Fiberglass Main Blades Thrust Bearing Main Rotor and Tail Rotor CCPM Direct Servo Drive Belt Driven Tail Full Driven Tail Auto Rotation System Frame Mount Tail Servo New Auto-rotation Main Gear Set with One Way Bearing (Belt driven).
