The Blade 120 SR – RC RTF Helicopter.
Looking for a larger Blade mSR?
The Blade 120 SR RTF, (Single Rotor) outdoor flying fun on those really calm days. Also available is the 120 SR BNF.
It has a main rotor span of 12.5″ (compared to the 7″ rotor span of the mSR) and is a single-rotor fixed-pitch helicopter.
Modeled after the Blade mSR, this sub-micro-sized Blade heli is larger, faster, and more powerful, which makes it possible to fly outdoors (in very light wind).
There are 2 settings on the inner swash plate, so when you become familiar with flying on the first setting, you can switch to a more aggressive setting, which gives a faster response for pitch. Almost like an upgrade to the next step without having to buy another heli.
Many pilots have also gone with the Spektrum DX6i programmable radio because of its features over the Blade 120 SR radio that comes with the RTF version, an inexpensive programmable radio with many features of more expensive models.
Already installed is Spektrums 2.4GHz DSM2 compatible receiver, main motor ESCs, mixer, gyro and fully proportional servos, all on its 5-in-1 control unit and a 1S 500mAh Li-Po battery, a single-cell, variable rate Li-Po charger, an AC power supply and a 2.4GHz DSM2 transmitter.
Blade 120 SR Problems – Flies For A Short Period, Then Drops Like A Low Voltage Cut-Off
If you are experiencing a problem where your 120 SR flies for less time than usual or when you first bought it, check your variable charger if you’re using the Celectra Variable Rate DC Charger that came with it and make sure it is set to charge at 0.3 amps. Although the manual says to charge it at 0.7 amps, that is way to fast for a Li-Po battery and will shorten its life span dramatically. For Li-Po batteries, it’s always best to charge at the lowest rate possible.
The SR 120 has become a popular upgrade for many micro rc helicopter pilots. It’s also a good idea to have a couple extra batteries on hand, like the E-Flite 500 mAh 12c Li-Po or the longer lasting Hyperion G3 Cx to be able to continue flying while the others are charging.
You can also add to your list of must – haves a Main Rotor Blade Set, Tail Rotor, Landing Skids, Mixing Flybar and Tail Boom Assembly With Motor, Mount and Rotor.
The 45 degree flybar over a 90 degree flybar gives the 120 SR stability similar to the micro-coaxial helicopter or the smaller mSR. Just like the mSR, it is equipped with an electric tail motor which can keep up with the torque of the main rotors surprisingly well.
Some may be discouraged about a separate electric motor on the tail rotor over a shaft or belt driven tail, but due to its smaller size and weight compared to the SR, Blade heli’s have accomplished this with excellent results.
With its larger and heavier frame, it withstands outdoor flying much better than the smaller indoor helicopters. With its increased speed and agility, there is more of a challenge and satisfaction of results.
Outdoor flying gives you more room, which in turn, gives you more time to react if in case you do get in trouble flying. It allows you to try new things with more room for error.
Watch a flight of the Blade 120 SR
The 120 SR has quality built in also. The landing skids, blade holders and flybar have a little give, so if a crash does happen, chances are you may not have to replace any parts. If something should happen, there are parts readily available, so that’s not a problem either.
This is a great transition from the mCX2, CX2, CX3 or mSR. That means if you already have a transmitter with DSM2/DSMX technology, you can get the Bind-N-Fly version and bind your radio to the new helicopter and is a less costly upgrade to your next level of experience. It gives you the confidence to get comfortable with a single-rotor helicopter. You can get the Ready-To-Fly version or the Bind-And-Fly version.
The Ready-to-fly version comes already set-up from the factory, so there’s no assembly or set-up required. One thing I did find was you may have to bind the radio to the helicopter once you get it, but that’s not a problem, super simple, just follow the instructions. The Bind-N-Fly version requires you to have your own radio with DSM2/X technology, binding your radio to the helicopter.
Although it is not recommended for your first rc helicopter, with a little patience and practice, research and reading the manual, your first time flying the 120 SR can be successful and enjoyable, making this possibly the best RC Helicopter of your collection.
This Is Not A Toy
It takes practice and dedication to learn how to fly properly. Treated as such, the Blade 120 SR should last a long time with years of enjoyment and satisfaction.
There are many Blade 120 SR parts and 120 SR upgrades available. Sometimes, it’s a good idea to have spare parts on hand to eliminate the need for waiting for parts in the event something should happen while flying. It’s also a good idea to have extra Batteries ($8.95) so you can still fly while the others are charging. If you don’t want to use A A batteries for the charger, the AC to 6VDC 1.5-Amp Power Supply ($16.94) is available.
