In 2019, OMPHOBBY revolutionized the world of RC helicopters with the first direct drive 3D helicopter, the M2 V1. This technology was developed throughout the M2 series and later redefined the 100 class with the M1 series, ultimately paving the way for the hugely successful M2 V3 PRO. After its overwhelming success, it was time for a major redesign of the M1...OMPHOBBY is proud to announce the new absolute standard in 100 size helicopter technology: the M1V3 PRO.
The M1 V3 PRO is a high-performance micro helicopter that caters to all possible flying styles. Compared to its predecessors, the M1 V3 PRO is designed to fly with more power, more authority, superior stability, longer duration and infinite confidence thanks to OFS3+, no matter how you fly it. With a 10% lower flight weight of just 112g (including receiver, equivalent to 110g without receiver), the M1 V3 PRO features the lowest rotor loads, the longest flight times and the best flight performance in its class.
Airframe Construction
The M1 V3 PRO construction has been completely redesigned to reduce weight wherever possible while maintaining incredible durability and performance. The frame design is based on the M2 V3 helicopters, which have proven to be extremely lightweight yet virtually indestructible in crashes. The central main plate forms the backbone of the frame and supports the engine, servo mounts with new improved DS2045LW V2 servos and the tail boom, while two robust carbon panels provide mounting points for the landing gear, propulsion battery and OFS3+ flight controller with ESC. Similar to its larger siblings, the fuselage is equipped with reinforcement plates at the rear to redirect forces in a crash, increasing the likelihood that key components will survive. All screws on the M1 V3 PRO are exclusively 1.3mm and 1.5mm Allen screws. No more special tools, no more compromises, you only need two standard Allen screwdrivers to maintain and repair the entire helicopter.
Rotor head
As the first model in its size class, the M1 V3 PRO has a main rotor head with thrust bearings. This significantly extends the life of the blade carrier bearings and at the same time offers smoother and more precise control of the blade attack angles, and thus rotor thrust and cyclic and collective steering. Together with the new rotor geometry and the new APEX 125 blades, this new, black anodized rotor head is ready to power and guide the M1 V3 PRO through even the most demanding 3D turns. It also allows for incredibly precise and smooth control at lower speeds. With a new rotor geometry optimized for OFS3+, the M1 V3 PRO allows for greater control authority than ever before.
Tail
The tail spar is now made of carbon tube, which increases durability and reduces weight. The minimalist tail motor mount ensures precise and fast yaw response while also serving as a heat sink for the new R11X-2 tail motor. This drives the new APEX 27 tail rotor, which significantly increases thrust; at the same time reduces noise and improves visibility compared to the original M1. The rotor hub and tail motor shaft are now studded, eliminating the risk of tail rotor slippage and reverse installation. The appearance is completed by a double-sided printed carbon fiber vertical tail stabilizer color-coordinated with the cabin.
Propulsion system
The M1 V3 PRO is powered by a newly designed and optimized R23X-2 brushless motor, which is lighter but more powerful than its predecessor on the M1. Power is provided by a new 2S 400mAh 50C LiHV battery with a gold-plated GY15 connector with robust contacts. Thanks to its smaller dimensions and higher current consumption than the previous JST-XH connector, it is designed for long life and guarantees a low-resistance connection. The connectors are also available separately and a charging cable is included in the package.
With this new propulsion system, the M1 V3 PRO features best-in-class efficiency and flight time, allowing for 20-30% longer 3D flights, sport flying and hovering compared to the M1.
Flight controller
This marvel of aeronautical engineering is controlled by the state-of-the-art OFS3+ flight controller with integrated ExpressLRS receiver. In addition, OFS3+ allows the connection of the receiver of the following systems:
Cabin
The M1 V3 PRO has a completely new, sleeker and more aerodynamic cabin shape and has adopted the four beautiful color schemes known from the M5, M6 and M7R models. In orange, yellow, pink and green, this helicopter will win the heart of every pilot!
The helicopter kit includes: Assembled M1 V3 PRO helicopter with rotor blades, LiHV power battery 7.6 V 400 mAh 50C, GY-15/XT60/JST-XH charging cable, CRSF/FrSky/KAVAN F.Port receiver cable, Bluetooth® module, set of servo levers, EPO foam case, instructions.
