E-flite’s Blade mCX is a hot heli and is a great flyer. It is available in both RTF and BNF versions for the pilots having their own Spektrum transmitter. It has become popular within a short time because of its excellent stability, easy flying for beginners and quick control.


The package of RTF version contains fully assembled Blade mCX heli, 1 15 3.7V 110mAh Li-Po battery, DC Li-Po charger, 4AA alkaline batteries for the Li-Po charger, 2.4GHz DSM2 4-CH transmitter, 4AA alkaline batteries to charge the TX, 1 small screwdriver, spare rings for canopy, 1 instruction manual.

The Heart of the Blade mCX

The central element of the Blade mCX contains the receiver, mixer, servos, gyro and ESCs, thus acting as a heart for the heli. When the battery is connected to this element, the gyro starts and the ESC gets ready. It is essential that the gyro works properly so as to make the heli achieve a properly upright and leveled position.

Inserting Batteries

Remove the bottom panel of the DC LiPo charger and insert four of the Alkaline batteries. Keep the bottom panel in place again and insert the LiPo battery in front of the charger as illustrated in the manual. The time for charging a depleted battery is around 30 minutes and when it arrived partially charged, it only took 10 minutes to get charged.  

A nice thing is the RTF version comes bound to the transmitter and test flown.


I received a mode II TX with my Blade mCX RTF version. The left stick is to control the throttle: up and down and also rotation in each direction. The right stick is for the control of direction backward and forward and also to either side. Digital trim buttons are present for these controls to facilitate adjustment so that the heli is as stable as possible with the help of control sticks while in neutral position.


A number of other transmitters are also compatible with Blade mCX. Among the Spektrum transmitters, only Spektrum DX6 is not compatible. So, E-flite’s LP5DSM, Spektrum DX5e, Spektrum DX6i, Spektrum DX7, JR X9303 and JR12X are all compatible. Moreover, modular radios equipped with a Spektrum module are also compatible.

Binding Blade mCX to Another Transmitter

When you receive the RTF Blade mCX it comes already bound to the transmitter and is test flown. If at all you need to rebind or bind a new TX to the 5-in-1 unit of Blade mCX or a new 5-in-1 unit to the TX, just follow the easy directions in the manual. They are also printed on the backside of the RTF transmitter.

  • Plug in the Li-Po battery into the heli and wait for 4-5 seconds
  • Turn the TX on
  • Center the left stick and push it down to bind the unit
  • Lower the throttle

Additional Parts

It is highly recommended to keep extra Li-Po batteries and an extra set of rotors.

There are several optional glow-in-the-dark parts and substitute parts which include main frame, skid, rotors, swashplate, canopy and vertical fin.

According to the manual you can have some 20 charges for the charger with the included 4AA batteries, which is correct because I could have 20. I might have to buy a few rechargeable AA batteries. The chargers work fine but slow down as the AA batteries get weaker.


  • Turn the TX on
  • Insert the battery in the holder under the heli
  • With the heli level, connect the battery to the lead from the control unit and it will properly start and prepare
  • Fly the heli
  • Land it
  • Unplug the battery from the 5-in-1 unit
  • Turn the TX off


The heli has coaxial rotation blades designed to offer a very stable flying platform by eliminating the rotational torque brought about by each blade. A tail rotor is not needed for stability. Directional control is achieved by servos forming a bit of tilting of rotors.

Take-off and Landing

Take-off is easy with only a smooth modification of increased throttle till lift-off occurs on its own. An experienced pilot can accomplish immediate precision landing, while a new pilot will require some practice.

It is recommended to land a bit early before the battery runs out of power, instead of extracting the last second of flight time. It is better for the battery.

Overall Flying

Blade mCX is designed for indoor flying. With a total weight of just 1 ounce it is quite prone to drifting with airflow from fans, open windows and air intakes. If you are fortunate to get a totally calm day, only then you can fly it outside. And because of its 2.4GHz system, you can fly it directly in sunlight, unlike most of the infrared-controlled helis.

micro size

Most of the new pilots may find it easier to move left stick and have the heli rotate to the direction they wish to travel and then to use the right stick to move to that position by going forward or backward, than using the right stick control (aileron control). They will be familiar with the side directional control of the right stick with experience and practice.


  • Compatible with many other transmitters
  • Literally ready-to-fly right after taken out of the box
  • True 4-channel
  • Hovers excellent
  • Good for beginners as well as experienced
  • Spare parts available easily


  • None as such, while price may be called one


Blade mCX is appropriate for both learners and experienced pilots. A beginner can get perfect training with its stable flight, while an experienced pilot will get a true joy of its all kinds of movements and excellent stability. Its size being much smaller than Blade CX2 it is pretty less frightening for a learner. And because it pushes less air, it is easy to operate it in a small space. Its dual rate makes it less reactive and smooth.
