Which One Should You Choose mSR vs mSRx
The Next Step From Fixed Pitch To Collective Pitch
The mSR is a good step up from micro coaxial to collective pitch, but I think the mSRx has become a better choice. The ‘X’ means no flybar. The flybarless system on the new Blade mSR X has taken care of some of the pitfalls of the mSR flybar version.
It’s definitely an improvement over the mSR and still shares some of the same characteristics. In fact, I think it’s the best step up to collective pitch out there.
The mSR has been replaced by the mSR x. You can still get Blades mSR, but I don’t know why you would, but the choice is still yours.
With the Spektrum AR7200BX receiver with integrated BeastX Flybarless technology, it is very stable, precise – sharp turns and the tail locks perfectly.
The 450 X uses a lot of the same parts as the 400 and 450, so parts support is great. This only comes as a BNF version, thinking most people looking for this type of bird already have a high-end radio and Li-Po’s.
If you’re looking for a ready built BNF. flybarless 450 size bird, then the 450 X won’t disappoint you. On the other hand, if you prefer to build your helicopter and get a far better machine, I would suggest the Align T-REX 450 Pro 3GX Super Combo .
The T-REX 450 has incorporated the new and improved 3G system, the 3GX flybarless system which uses a 16 bit processor making it much faster than the old 3G system.
To see just exactly what you’re getting into with the Align T-REX 450, here’s a great video to watch to help make up your mind if you want to try and tackle something like this.
Align T-REX 450 Pro 3GX Super Combo – What’s In The Box
When you receive your new Blade mCX2 Coaxial Helicopter, unpackage it and read the directions carefully. You will first need to install the batteries in the radio (transmitter) and charge the battery for the helicopter. After that has been done, you will need to “Bind” your radio to the helicopter. That means that your helicopter will respond to the input controls from your radio. Instructions about how to do that come with the Blade mCX2.
To bind your helicopter, you need to plug the charged helicopter battery into the helicopter, at this point DO NOT turn on the radio yet, there will be a blue flashing LED at the front of the helicopter after the battery being plugged in, after a few seconds. Before turning on your radio, push down and hold the left “control stick” like you’re pushing in a pin, it will click, and turn on your radio, it will start beeping, let go of the control stick and after the radio has 1 longer beep, the radio and helicopter are “bound”.
To see if the radio and helicopter is “bound,” move the “right” stick around and see if the control surfaces move. If they do, you have successfully bound the radio to the helicopter. If they do not, go through the steps again to bind them together, making sure you have done the steps correctly in the right order.
First Flight Of The Blade mCX2 – DO NOT attempt to fly outdoors
Even though the mCX2 comes set-up and trimmed from the factory, that’s not always the case, at least in my experience, there’s usually still a little trimming of the controls to get it trimmed properly. With that being said, see if your new heli needs to be trimmed. After the batteries have been installed and the radio and helicopter have been “bound”, familiarize yourself with the radio controls. The mCX2 comes with a 4 channel – 2-stick radio, 2 channels on each stick. Each stick will move forward and backward and left and right.
4 Channel Radio
The left stick is the throttle (forward and back) and left and right turn. You’ll notice the forward and back movement on the left stick are not spring loaded as the other directions on all other control movements for the other 3 channels, that is so you can maintain a constant throttle (speed). The left stick, right and left movement turn the helicopter left and right. The right stick also has 2 channels, forward and back and left and right. Forward and back moves the helicopter forward or backward and the left and right move it (sideways) left and right.
To see if your helicopter needs to be trimmed, look for little buttons along side and below the sticks, they are your trim “tabs”. Ideally, you’ll want to set up your helicopter so that when you give it just enough throttle to hover about a foot off the floor, it will stay in one place and not “drift” in any direction. You will find 3 trim tabs; the throttle will not have one. The trim buttons along side of the stick will trim forward and back and along the bottom of the sticks will trim left and right. Remember, the left stick, right and left direction turns the nose of the helicopter left or right. The right stick, right and left direction, “pushes” the helicopter sideways left or right.
Start out by slowly pushing the left stick forward until the main rotor blades start to spin, then continue until it hovers about a foot off the floor. If it wants to drift around, even slightly, adjust your trim tabs opposite of the direction it’s drifting. So if your hovering and it slowly spins in circles, lets say to the left, then push the button under the left stick 1 click to the right until it quits spinning. Do that for any other “drifting” as well.
Flying Around The Room
When you begin flying, practice getting used to the controls and how the helicopter responds. You’ll notice when flying at a certain height, any input from the radio, forward-backward, left-right, etc. will cause the helicopter to lose altitude, something you will get used to over time and with practice. Also, smaller input will reduce that as well.
Coaxial, counter-rotating blades cancel out the rotational torque that makes hovering a conventional heli so difficult. Instead of a tail rotor, they use differential rotor speed for tail control so the inherent stability of the counter-rotating blades is preserved.
Easy to replace and very inexpensive, this is the Replacement BLH3117 tail rotor for the Blade 120 SR. There have been some complaints about the tail rotor being too easy to bend and won’t stay true to their shape.
Blade 300 X
The Blade 300 X will give pilots transitioning to a collective-pitch heli a more agile and capable helicopter that will give them the confidence to master indoor aerobatics. It comes in the RTF (Ready-To-Fly) and BNF (Bind-N-Fly) versions. It is a 300 size platform without the flybar, which reduces the drag on the main rotor and in turn, results in more power and longer flight times.
It comes equipped with a 2.4GHz DSM2 transmitter (RTF), factory-installed Flybarless 3-in-1 Control Unit, Spektrum 2.4GHz DSM2 receiver, ESCs and gyros, two 1S 200mAh 25c batteries, single port charger with AC adapter and a 1s High Current Ultra-Micro Battery Adapter Lead. The BNF version comes with everything but the transmitter.
Some of the features are:
- Belt-driven tail rotor with weighted tail blade hardware
- Tail grips with thrust bearings
- AR7200BX 7-Channel DSMX Flybarless Control System
- 320H 4500Kv brushless motor
- 25A S-BEC brushless ESC
- Includes 3S 1350mAh 30C Li-Po battery
- DC Li-Po charger
- Symmetrical Main Blades - The high performance rotor blades give you full 3D performance
- Composite Aluminum/Fiber Reinforced Swash Plate
- Triple Ball Bearing, Hardened Steel Main Shaft – Ball bearings support the main shaft at the top and bottom of the drive gears and the top of the frame.
- DS76 Cyclic Servos and DS76T Tail Servo – The DS76T has extra speed for instant tail response
- Aluminum Tail Boom – Keeps tail response precise
The 5 in 1 control unit is this little circuit board that houses the RX (Receiver), ESC (Electronic Speed Control), Mixer (increases the tail rotor speed as the main rotor speed increases), Gyro and Servos (micro linear servos control the cyclic functions on the swashplate).Consider this the “brains” of the 120 SR as it has a lot of things built into this small unit.
This Quadricopter has been designed to be incredibly responsive and fun to fly, thanks to its AS3x (Artificial Stabilization 3-Axis System). The AS3x system keeps stabilization for yaw, pitch and roll. It maintains stability whether indoors or out in breezy conditions. It comes in the RTF version and the BNF version for those who already have a radio equipped with DSM2 or DSMX technology. It also has 2 modes to fly with, the “X” configuration like in the picture above or a “+” configuration, as in this picture. The orientation on this quad is slightly improved with the 2 white blades in front, keeping that in mind as you fly.
