5 Appealing Blade Nano S2 Upgrades and Modifications

The blade nano s2 created a wave across the nano RC heli lovers as it lays a path to 3D aerobatic expertise that’s paved for success. Its redeveloped stabilizing system offers flips and inverted flight easy for pilots at all skill levels to master. 

However, these features may sound the best, but you can make them better.

This blog explains everything you need to know about blade nano s2 upgrades. Down from the quality of upgrade parts, performance up to the cost estimations. I’ve got you covered, so stay tuned!

Blade Nano S2 Upgrades

How Much Does Its Cost to Upgrade?

The entire upgrade will cost you about $550-925. 

Upgrade the motor at $150 to 200, $15-20 on battery, $12-50 on servo/steering, $30-40 on the ESC, and $30 to 50 on the tail rotor.

You can upgrade other accessories for $30-50 dollars.

5 Blade Nano S2 Upgrades:

The helicopter is constructed of plastic parts mostly. But it is important to maintain the weight ratio to taking a flight.

Moreover, this heli uses a servo and a swashplate as a steering mechanism.

Our goal will be to upgrade the parts to build a sturdy, more controlled steering and optimum flying on the best budget.

The nano heli is very strong and sturdy. But it lacks some changes that will make it a superb one.

You and I today will build a more 3D flying appropriate RC helicopter by upgrading (or sometimes downgrading in this case! You’ll see!). The costs along the way will be presented below.


While upgrading the parts, it is crucial to maintain the weight ratio. Keeping the weight of your Nano S2 as low as possible is an important factor as the weight can affect everything from flight time to tail hold to flipping performance. You can keep the weight on the low side by getting rid of the connectors or shortening the wires. 

And for S2, it is important to configure the throttle cut to the same switch as the throttle hold. A throttle cut is needed to stop the motor in 3D mode on the S2.

1. Motor

The default motor is the brushed one. But suppose we upgrade it with the brushless motor. In that case, this BNF RC helicopter will be more efficient as brushless motors are better adapted, produce less heating with no friction, and provide better performance.

So, I recommend the manufacturer to go for brushless motors to avoid unnecessary hassle.

There are two options given below – one is expensive and the other one is a budget-friendly option.

1st option: E-flite Power 90 Brushless Outrunner Motor

2nd option: Great Planes Rimfire 370 28-26-1000Kv Brushless Outrunner

2. Battery

The stock battery is around 150mAh 1S LiPo which comes with a USB LiPo battery charger. The battery has a charge span of 4 to 5 minutes. 

That’s why I am suggesting two options for your Nano S2 helicopter. These batteries come with more power and longer battery life.

1st option: 3.7v 250mah Lipo Battery for GBlife Bounce Car Holy Stone

2nd option: sea jump 5PCS 3.7V 380mAh Battery+Charger

3. Esc

The included electronic stability control is super sensitive. It would be best if you upgraded it to enhance the lifespan. The decent place to mount the ESC is in front of the receiver board.

You can use double-sided padded tape to mount the ESC onto the receiver board without interfering with the blue/red LED on the board.

You have to keep in mind that the wires don’t tilt the board or restrict the flexibility of the rubber mounts. I am suggesting both expensive and affordable choices.

1st option: Blade BLH5105 Brushless ESC

2nd option: Blade BLH5052 Brushless ESC 

4. Tail rotor

The tail rotor is mounted vertically at the tail, where it rotates to generate a propeller-like horizontal thrust in the same direction as the main rotor’s rotation. Without the tail rotor, the helicopter would constantly be spinning in the opposite direction of the main rotor when flying.

At first, I thought the tail rotor might struggle a bit to keep up with the brushless motor. However, the tail motor keeps up quite nicely.

You can upgrade it with my suggested one when the stock tail rotor gets exhausted. The default one is 40mm, and the one I am suggesting is around 100mm.

Suggested tail rotor: Walkera Tail Motor for Master CP 

5. Servos and Swashpates

The Linear servo and Continuous rotation servo are quite the same, but the former comes with additional gears (usually a rack and pinion mechanism) to change the output from circular to back-and-forth. But these linear servos are not easy to find. 

Since this nano S2 comes with linear servo, you can change it with continuous rotation servo as it is available. And this rotational rotates clockwise or counterclockwise as desired, at varying speeds, depending on the command signal.

The stock swashplate is CCPM. You can also install an AL swashplate. After a right trim flight of the Al swashplate, it can transmit three of the pilot’s commands from the non-rotating fuselage to the rotating rotor hub and main blades.

You will use the servo trim parameters to level your swashplate if you aren’t using the Linearize Servo feature. 

And if you intend to use Linearize Servo feature, then you will have to level your swashplate using the pitch links that connect the swashplate to the servo.

1st option for Continuous rotation servo: DIYmalls Feetech FS90R Micro Continuous Rotation Servo Motor 

2nd option for Continuous rotation servo: Geekstory Feetech FS90R 360 Degree Continuous Rotation

Linear servo: L16 DC Linear Servo Motor 100mm Stroke

Swashplate: GarttDS505 Swash Plate servo


Did you like the blade nano s2 upgrades? If you are a 3D pilot that wants to smack around a nano-sized heli without eating through brushed motors, or just learning flipping and inverted flight, then this upgrade is for you!  However, if you are happy with the Agility mode, Safe mode, or Stability Z-mode, I suggest you continue with the stock motor for a while longer.
