Heli RC OMP Hobby M5 KIT 550 Yellow
Introducing OMPHOBBY M5!
Closing the gap between M4 MAX and M7, we're beyond thrilled to announce our latest line of helicopters. Built for everything from low RPM cruising and scale flying, to relentless hardcore 3D, M5 are ready for anything and everything. With a shared parts count of over 90% between them, these two helicopters are the most versatile and adaptable airframes we have ever built
The main rotor design found on these two helicopters is a direct derivative of the M7 rotor design. Long control throws, integrated and retained rotor blade washers, extremely durable and beefy 5mm ball joints, and two damping options, are all part of a large diameter rotor head mounted on a 12mm shaft. Combined, these attributes provide unparalleled precision and control that make M5 and M6 fly every bit as amazing and rock solid as M7, while being incredibly agile in the air!
For anti-torque and yaw control, M5 and M6 inherit the same style of one-piece tail rotor housing, slop-free bell crank mechanism and extremely robust tail rotor design used on M7, downsized to fit an ultralight 28mm carbon fiber tail boom, while retaining the same 6mm tail shaft and 5mm spindle shaft diameters. The 6mm wide tail drive belt can conveniently be adjusted on-the-fly, using the same helically driven belt tensioner system found on M7.
With a wide range of pinions ranging from 11 to 15 teeth, and two incredibly durable, 15mm tall, FEA optimized main gear options (M5: 115), you are guaranteed to find the perfect gear ratio for your personal setup. The motor mount now sits on rails on the main plate, both increasing rigidity of the assembly and guaranteeing parallel shafts every time. The airframe can accept any battery configuration into a spacious 58 x 70 x 300 mm battery bay. Since both M5 and M6 use the same basic frame structure, M5 battery trays fit M6 without modification, and vice versa, and both are latched by the same, convenient twist-lock system derived from M7.
Main rotor blade grip, Main rotor hub, Swashplate outer ring, Main plate are CNC machined from forged aluminum alloy, while the remaining components are made from 7075 aluminum alloy via CNC processing, ensuring a lightweight yet robust structure. The upper and lower sides of the airframes are connected with three-layer carbon fiber plates, forming a robust airframe structure that provides stable rigid support and durability while ensuring easy maintenance.
Canopy Quick release connector are installed from the factory.
The vibration-isolated FBL platform with an optional mass damper.
The universal 6-12S battery rail offers high expandability. The quick-release battery plate mechanism ensures easy operation and safe, reliable flight.
Features:
MS and M6 combine the best attributes of M4 and M7 into one attractive package. An elegant, open frame design, carried by a sturdy main plate with a compact and efficient servo rack design, combines easy maintenance and wiring. This is completed by an unbelievably stiff, layered carbon frame with beautifully chamfered edges on the lower panel. M5 is designed for modern 35mm servos all around. If desired, M5 can be crossgraded to 40mm servos using M6 parts. Integrated wiring guides make routing your wires a breeze!
