Estes 4606

The Estes 4606 Proto X Nano

is an absolutely tiny quadcopter, measuring only 1.8 x 1.8 inches. Inside the package, you’ll find:

  • The quadcopter itself
  • An 2.4 Ghz radio transmitter for the quad
  • An USB charging cable
  • Four replacement rotor blades
  • And finally the instructions

The quad is well built, and can take a beating. Due to it’s small size it can’t crash really hard. While it really shines indoors, you can fly it outdoors too if there is no wind. Be careful though – the quad comes without guards (though they are available). Replacement props are included, so it’s one less thing you will have to worry about.

The quad is tiny (1.8 x 1.8 inches, 0.4 oz), so the range is small too (you would loose sight of it anyway). The quad has LED lights: blue in the front, and red in the back, which help with the orientation during flight.Due to it’s small size it’s fairly quiet, so indoor flying will not disturb your peers (harassing your friends is never recommended 🙂

Automatic landing is not supported, but landing is easy: just start hovering, then gently lower the left stick to let it land.

Due to it’s tiny parts it can be dangerous to little children, so keep it out of their reach. The suggested minimum age is 8 years, in reality you will want to wait a bit more.

If you happen to have a Hubsan X4 V2, you may want to pair the Estes 4606with it’s transmitter: they are compatible, and you might get additional functions, like turning the LEDs on and off, flipping, and so on.

Stability is great so you will not have to keep adjusting it. The accelerometers might need recalibration after an accident; to do this put the Proto X on a flat surface, and throttle down. Move the left stick to the bottom right corner, and move the right stick to the left and to the right until the LEDs start flashing.

Shipping weight is 3 pounds, shipping dimension is 5.5 x 4 x 2.5 inches – good to know if you plan to take it on a trip.

Third party crash guards and rotor blades are available, would you be into hard flying 🙂

Quads this tiny do not need to be registered, which is a plus.

The battery

is a 100mAh one, with a flight time of 4 to 6minutes, and a charge time of 40 minutes. The battery is not replaceable,which is the Achilles heel of this otherwise perfect quad.

Charging is through a USB based adapter, so you will need either a computer,an adapter or – if you are out in the field – an external USB charger is great too.

The transmitter

is tiny, simple, but more than adequate for the purpose. It needs needs 2xAAA batteries, which might not be included. Using rechargeable batteries is a great idea!

The transmitter uses standard 2.4 Ghz technology, so you will not get interference, and it also makes it possible to replace the Tx with a more powerful one.

The transmitter is mode 2 only – if you are new to flying this is not a problem though. Also, this issue can be solved by using a different transmitter.

The transmitter and the quad are bound at the factory, but rebinding is easy too:

  • Turn on the quadcopter.
  • Push the left stick (the throttle) down and turn on the transmitter.
  • Wait for the on the transmitter to turn green.
  • If the LED is flashing, replace the transmitter’s batteries.
Our Rating:

While this quad flies great and is fun to boss around, the non-removable battery is a minus.

You may want to check what others think on Amazon too. The CheersonCX-10 is in the same class with a bit softer looks, so you will want to check that too for sure. To learn even more about the Estes 4606 the RCGroups thread is a great source, and the manufacturer has his own list of reviews too.
