CCPM swash plate controlled by electronically mixed servos, flybarless rotor head with a new, now fully adjustable in a mobile application 3G 3-axis gyroscopic system instead of the classic mechanic stabilizer and tail gyro, powerful brushless motor and electronic speed controller with the governor function, smart flight control unit featuring attitude stabilization mode for beginners as well as 3D mode for aggressive aerobatics - you will find all that packed in the M2 EVO MK2 mini helicopter with 434 mm diameter main rotor!
Let’s take a closer look at this latest gem of the OMP Hobby design. The airframe consists of precision machined 7075 aluminium motor mount and main shaft housing with carbon side frames and brackets, durable plastic landing skids and aluminium tube tail boom with carbon vertical stabilizer. The new powerful brushless outrunner motor Sunnysky® R40 with higher 750KV drives the main rotor directly without any gearbox. The tail rotor is being driven directly by the Sunnysky® R13-3 brushless motor. This makes the mechanic extremely simple; there are no more problems with “non-slidy” sliders, stripped gears or slipping drive shafts.
The massive 4 mm steel main shaft is housed in precise ball bearings; the swash plate and rotor head are machined from high strength 7075 aluminium alloy. Thanks to the 3G flybarless system and CCPM mixing the newly optimized geometry main rotor head is surprisingly simple yet state-of-the-art piece of machinery. The main rotor blade grips are perfect miniature of the “full size” RC helicopter grips - with all those bearings and damping rubber rings!
The electronic system consists of the new OFS3 smart flight control unit integrating 3G flybarless unit, main rotor electronic speed controller with the governor function, tail rotor ESC; and three digital micro servos (1.65 kg.cm, 0.08 s/60°) with metal gears controlling the 120° CCPM swash plate. You will need at least 6-channel RC set with a miniature S.BUS (or DSM2/DSMX and now also the duplex CRSF protocol with telemetry - supported are TBS Crossfire, Tracer and ExpressLRS systems) compatible receiver to control your M2 EVO MK2. For the basic, non-aerobatic flying, the transmitter eves does not have to feature any heli program (the control unit does all the helicopter mixes) - you will just need 4 channels “on the sticks” and one 2-position switch for attitude stabilization/3D mode switching. Of course, for “full-fledged” classic and 3D flying, a computer transmitter with 2-3 flight modes with at least 5-point collective pitch curves is needed for the hovering and aerobatics plus the throttle-hold mode for autorotation landing/aerobatics. Thanks to the broad adjustment capabilities of the flight control unit in the mobile app (including detailed setting of the PIDF parameters of the control loops) you can most of settings, that required an advanced computer radio in the past, make on your smartphone in the App (available for iOS as well as Android systems). You can, but you don’t have to - the flight control unit is supplied completely pre-adjusted; you can tweak the basic parameters using a button and LED array on the OFS3 as it was with the previous OMPHOBBY control units if necessary.
The easily detachable canopy is moulded of durable, yet light plastic - you can choose from three high visibility colour schemes ensuring you can always “read” the position of your helicopter in the air. The flight pack is three-cell 11.1 V 750 mAh 60C LiPo battery (XT30 connector) placed in the easily accessible battery seat. It ensures up to 10 minutes of regular flight or up to 4 minutes of aggressive 3D aerobatics.
The helicopter is supplied fully assembled with pre-programmed flight control unit; so you just have to take it out of the box, install your S.BUS/DSM2/DSMX/CRSF compatible micro receiver, charge the flight pack, set -up your transmitter following the detailed step-by step manual, double check all the helicopter control functions - and you can take off!
The M2 EVO MK2 is fully-fledged 3D helicopter with collective pitch control - as such it requires considerable pilot skills to be flown. It is not a “drone” requiring just pushing the throttle stick up and then hovering, no matter what, without any control input from the pilot. Intermediate or advanced helicopter pilots (who have already mastered flying with helicopters featuring the collective-pitch control) will truly enjoy the M2 EVO MK2. However, with the right dose of humble perseverance, thorough PC helicopter simulator training, under the supervision of a skilled pilot and with the attitude mode on, the M2 EVO MK2 might be your first “fully-fledged” helicopter.
The ready to radio set contains: 100% assembled, ready to fly M2 EVO MK2 helicopter, Bluetooth® module, 11.1 V 750 mAh 60C LiPo flight pack, spare main shaft and main rotor shaft, spare servo arms and small screw set, swash plate leveller, sturdy EPP foam box with hinged lid for safe transport and storage of the model, instruction manual.
