Overview:

I received my Devention MTC-01 today.
I tried it out on my WK-2801 Pro with firmware version 2.2
It was fast and easy to use. I made a How to video to show how to use it and bind with it.

The first thing I wanted to check was to see if I had the same problem that zadaw had.

I didn’t have the problem zadaw had. I thoroughly tested the MTC-01 with my Ladybird, Mini CP, and Master CP.
Once I was sure the unit was OK with the current version firmware I updated the firmware.

Here is there note that comes with the new version firmware:

“This programe Improved a loose connection caused by Channels mixed up issue. ”

After the firmware update I tested everything again.

 

First Flight:

My first test flight using my Ladybird went well.
The second test using my Mini CP went well also.
So it was time to shoot some video.
First flight was going to be with the ladybird. I bound the ladybird and hit record
on my video camera.
As I walked around the ladybird took off full throttle on its own. I had no control of it
with the transmitter including throttle hold. I had to chase around the ladybird as it hit the ceiling and walls.
Once I got it I unplugged the power. Since I am doing testing I decided to try again.
I bound the ladybird and this time was ready for it to take off. What happened the first time
and happened again was I bumped the cable that goes from the TX to the MTC-01.
As soon as the cable connection was touched the heli took off on its own with no response from the transmitter,
it was like it was turned off as I tried to gain control of the ladybird and also hit TH.
I pulled out the plug that goes into the DSC port on the TX and plugged it back in.
I fired up the ladybird holding it in my hand this time and I moved the cable all around and the
connection was fine.
I did have it in completely the first time ( I checked both ends of the cable connections) but maybe the DSC port socket had some oxidation on it.
I then made my two indoor videos with no problems.

 

 

 

Pros:

  • Very easy to use
  • You can use your older transmitter with the newer Devo RX Helicopters and Quads.
  • You can fly your Helicopter or Quad using your Smart Phone with the RC-Copter Software (Android App).
  • The RC-Copter Software has a good fail safe.
    If I remove the magic cube or turn it off the Helicopter or Quad will just turn off and not take off on its own like it does using it with a transmitter plus no controls work either including throttle hold.

Cons:

  • No low voltage warning alarm on the magic cube. When the voltage gets low two LED’S will flash.
    You are not going to see the LED’S flash with it stuck on the back of the transmitter.
  • No fail safe for the magic cube. If it shuts off due the battery runs out or if the connection is broke even for a split second
    the helicopter or quad will take off on its own with no response with the controller including throttle hold.
    Walkera should address this issue if possible unless they can’t make a fail safe using the TX and magic cube together.
  • Output power less than 10mW. Should be fine for micros as you can’t fly them too far before they get too hard to see.

 

Conclusion:

The Magic Cube is very easy to use and works well.
All you need to do is create a model in the transmitter and plug in the Magic Cube and bind.
I highly recommend you do a connection test before you try to fly anything to avoid the problem I had.
I would take off the blades and bind the heli/quad. Then wiggle and move around the
cable on both ends to make sure you don’t have a connection problem like I did. If this test works OK then it should be safe to fly.
Also make sure the magic cube is fully charged and your transmitter also.

 

Update: 11-7-12

My magic cube has been in storage and it will not be used again unless
walkera improves the firmware and gives us a fail safe for it when it is used
with a transmitter. The fail safe is good using the android app. If the connection is lost or even if you turn off the magic cube or pull it out of the phone the heli or quad will just turn off and not take off on its own which happened to me a couple times even with the new firmware.

I don’t recommend the magic cube due to there is no fail safe when using it with a transmitter.
If you do use it I wouldn’t use anything bigger than the ladybird or mini cp.

 

Update: 12-1-12

I just tried the new Magic Cube V2 with my WK-2801 Pro.
It now has a failsafe and a good one at that!
I tried pulling out the connection and this time the heli just shut off instead of taking off on
me full throttle with no control at all with the transmitter like the first version.
Also if the heli is in flight and the connection is broke or the MC power is turned off it will
shut the heli off with a soft wind down which is nice.
Looks like they got it right with V2!

 

 

I tried the following:

  • Pulled the MC connection while the heli was bound. The heli shut off.
  • Turned off the MC power while the heli was bound. The heli shut off.
  • Turned off the TX while the heli was bound. The heli shut off.
  • Turned off the MC power while the heli was bound and running full speed in my hand. The heli shut off with a slow wind down.
  • Turned off the TX power while the heli was bound and running full speed in my hand. The heli shut off with a slow wind down.

The Magic Cube V2 has an extra IC Chip and some more surface resistors. Also it doesn’t have the small red jumper wire.
The MC V1 says v2.0 on the circuit board and the MC V2 says v2.1 on the circuit board.

Presenting the Walkera MTC-01 “Magic Cube”
It turns WK transmitter and a DEVO Transmitter, very useful item for old WK transmitter owners.
You tape this “Magic Cube” on the back of your WK transmitter (eg. WK2801-Pro),
and connect that cable into the “DSC” hole, turn on the power on the “Magic Cube” , and turn on your transmitter, then you got yourself a DEVO transmitter, which is able to control the latest Walkera products, because all the latest products are using DEVO protocol, not WK protocol anymore.

 

Features:

1. Frequency: 2.4G frequency hopping
2. Output Power : less than 10mW
3. Electrical current : less than 35mA
4. Battery : Built-in 3.7V 80mAh lithium polymer battery (Re-chargable by USB cable)
5. Weight : 10g

When MTC-01 power indicator and binding light flashing at the same time means you need to charge the inner battery at once.
Charging Voltage: 5V Charging – Current: 500mA

Walkera RC Magic Cube MTC-01 and the RC-Copter Software (Android APP for the Android OS above v2.0).

Overview:

The RC-Copter Software is an Andoid App that lets you fly your helicopter or quad with your smartphone with an OS
of 2.0 and higher.
All you need to do is install the RC-Copter Software, plug in the magic cube into your phone in the headphone jack, turn the
headphone volume to max, and go through the settings for your helicopter or quad. Then bind and your all set to fly.
I made a How to video that shows you how to bind.

The RC-Copter Software has a good fail safe.
If I remove the magic cube or turn it off the Helicopter or Quad will just turn off and not take off on its own
like it does using it with a transmitter plus no controls work either including throttle hold.
Walkera should address this issue if possible unless they can’t make a fail safe using the TX and magic cube together.

I recommend you put your phone in “Airplane Mode” when you use the RC-Copter Software.
This way if you get a phone call while you are flying the call won’t stop the android app from running.

If you still can’t get your heli/quad to bind after watching my video try this:

Play a song on your smartphone then turn up the volume up to max.
Then plug in the magic cube and your speaker should turn off. Then open the RC-Copter Software Android app.
I did this so I know the headphone jack worked and the volume was at max.

Go through the binding process again and when the blue ID LED
stays lit which is suppose to flash press the binding reset icon one time then press and keep pressing
the bind icon dozens of times. If the blue ID LED still does not flash then press the binding reset icon one time again
and then press and keep pressing the bind icon dozens of times if needed.
Keep repeating this back and forth until the blue ID LED flashes.
I had to go through all this.
The next time it you use the app it will bind the first time you press the bind icon.
But if you reset or turn off your phone you will have to go through all this again.
At least this is what I have found out.
