E-Flite Blade CX 2

The Blade CX 2 co-axial electric rc helicopter, from E-Flite, follows on from the hugely successful Blade CX, with a sleeker looking body design and digital radio.

The E-Flite Blade CX 2 helicopter

Co-axial electric helicopters like the Blade CX 2 are an ideal option for (but not limited to) the beginner rc helicopter pilot - they are extremely stable in the air and are easier to master than a conventional single rotor/tail rotor model.
In fact, quality RTF co-axial helicopters can pretty much be flown out the box, and the E-Flite Blade CX 2 is indeed one of these.


The Blade CX 2 radio system

The Spektrum tx for the Blade CX 2

It's the radio control system that sets the Blade CX 2 apart from the rest, but it's inevitable that more and more rc helicopters (...airplanes, cars & boats...) will use digital radio systems in the future.
The particular type of control is called Spektrum Technology (2.4GHz DSM Spektrum technology, to be more accurate) and is the kind of signal transmission system used by the likes of NASA and the military. In a nutshell, the transmitter to receiver signal is digitally encoded and it is virtually impossible for anything to interfere with the unique code (1 out of over 4 billion available codes!) assigned to your particular radio system.

As soon as you turn on the tx, the whole 2.4GHz frequency band is scanned in a matter of seconds, and a free channel (79 available for rc use) is immediately locked onto - that channel is then secure until you turn off the tx.



Other CX2 details

The Blade CX 2 comes, as standard, with two 180 size motors and a 2-cell 7.4V 800mAh Li-Po battery pack, which combine to give flight times of between 10 and 15 minutes.
The supplied 2/3 cell LiPo balancing charger is ready to connect to a 12V battery for field use, but also supplied is an AC mains adaptor for charging at home. A full charge takes about one hour so, as always, it's not a bad idea to purchase a second battery pack if you'd rather not wait on charging times!

Each Blade CX 2 is test flown at the E-Flite factory before being shipped out. It's stability in the air makes it a perfect beginner's choice, and there is a good range of spare parts available should the worst happen, many of which are compatible with the original Blade CX.


In summary, the E-Flite Blade CX 2 is without doubt one of the most attractive looking co-axial electric rc helicopters available at the current time (early 2007) and is one of the most easy to fly straight from the box.
Its Spektrum digital radio control system will be used by all rc aircraft in the future, but the Blade CX 2 is the first mass-produced RTF aircraft to do so, a very noteworthy credit indeed!
