You may have noticed that we enjoy our quadcopters here at Gizmag, from the GPS-equipped Phantom 2 Vision to the palm-sized 1SQ V-cam. Recently though, we had a chance to try out a somewhat unusual style of quad in the form of the tiny Proto X from Estes. It may not have a laundry list of features under its belt, but the Proto X does hold the distinction of being the smallest quadcopter we've ever reviewed ... by a huge margin.

What's in the box

The Proto X costs US$39.99 and comes ready to fly with its own controller right out of the box.

Inside the package, you'll find:

  • the Proto X quadcopter
  • 2.4 Ghz radio transmitter
  • USB charging cable
  • four replacement rotor blades
  • instructions

The only necessary components missing from the box are two AAA batteries, which are needed for the transmitter. However, fitting them into the controller and charging the quadcopter via USB are the only steps needed before the Proto X is prepared to take off.

A pocket-sized UAV

I really can't stress enough how incredibly tiny this quadcopter is. It's actually a little startling to pick it up for the first time, because it isn't much bigger than some insects you might find in your backyard.

Estes claims it's one of the lightest quadcopters in the world with a weight of 0.4 oz (11.3 g). Measuring from the tip of the rotor blades, each of its four sides is approximately 2.5 in (6.4 cm) long. Even the frame by itself is just 1.8 in (4.5 cm) on each side, giving it almost the exact same footprint as a typical saltine cracker.

The included radio transmitter is built to match, measuring a little over 3.5 in (8.9 cm) wide and 2.5 in (6.4 cm) wide, making it look vaguely like a shrunken video game controller. Even put together, the copter and transmitter are compact enough to fit inside a regular pants pocket.

Piloting a bug

Due to its size, flying the Proto X feels like guiding a large bug, right down to the faint buzzing noise it makes. If it weren't for the LEDs that light up when it's switched on, it would be difficult to keep track of it at a distance. My haphazard attempts to take photos of it in flight with an ordinary digital camera made me sympathize with anyone who's tried to record a UFO.

Once you get used to following it though, it flies about the same as a full-sized model. The controls are straightforward – left stick for altitude and rotation, right stick for direction, plus a couple buttons to adjust the trim – and an internal gyroscope keeps it flat while in the air. Hovering in place takes a bit of practice though, since the slightest breeze will knock it off course and the bundled transmitter can be difficult to use (more on that later). I've spent a couple hours flying it and still have trouble keeping it perfectly still in mid-air, though it's not too hard to guide it in the basic direction I want it to go.

The box and instructions say it's intended for indoor use, so that's where I flew it most, but I did take it outside once just to see how it would handle. After a gust of wind blew it far away after it had barely lifted a few feet off the ground though, I understood why the manufacturer had made that call. It might fare better on a nicer day, but in my area, this isn't exactly the time of year to find out.

On a full charge, the Proto X can remain aloft for approximately 10 - 15 minutes. When it's about to run out of power, the LEDs near each rotor will begin to flash rapidly, at which point it has about a minute left of flight time before it slowly floats to the ground and stops. To maintain the quadcopter's balance, its 3.7 V 100 mAh LiPo battery is secured inside the plastic body, so unfortunately you can't extend that flight time by swapping batteries. Once the battery is drained, it takes about 30 minutes to completely recharge it.

Made for small hands

The main hindrance when piloting the Proto X though is the controller itself. Holding the transmitter feels like holding a child's toy, especially if you have larger hands. There's really no comfortable way to grip both thumbsticks at once without folding the rest of your fingers awkwardly out of the way. I understand the designers probably didn't want to ship a regular-sized transmitter with the nano copter, but even just a couple extra inches in width could have made the controls much less cramped.

The trim buttons are also located in spots that are difficult to reach when controlling the quadcopter simultaneously. Adjusting the trim usually involves landing, pushing the button for the desired direction, taking off again to see if it worked, and repeating until it seems to be hovering correctly. The controller also doesn't have trim buttons for the copter's rotation, just for the direction it flies, which could have been useful at times.

Tough little bug

Because of its size, I thought it might need to be treated delicately when I first pulled it out of the box, but the tiny Proto X quad seems to be just as durable as its larger brethren. Crashing at full speed into walls, dropping straight onto a hardwood floor from as high as the ceiling, and even ricocheting between a chair's legs did nothing to faze it. The worst damage it suffered was when a rotor blade popped off during a crash, which was easy enough to retrieve and put back in place.

At one point when it was hovering in place, my dog actually leaped up and snatched it right out of the air. He released it almost immediately, and I made sure to get him out of the room before flying it from then on, but the quadcopter still came out of it without even a scratch. I doubt it would survive being stepped on or dropped off a building, but it's still nice to know it can survive a few mishaps during regular use.

Overall impressions

Aside from its novelty size, there aren't too many standout qualities to speak of on the Proto X. It doesn't have a camera, it can't perform any fancy tricks, and it's not really designed to be reprogrammed or customized. That said, for the price, it is a simple and dependable quadcopter that's easy enough for beginners to pick up. If you're looking for an R/C quadrotor with a myriad of features, then the Proto X is not going to cut it. However, if you're just looking for a tiny quad that you can fly around your living room or office for fun, then it should fit the bill perfectly.

Since Estes is a subsidiary of Hobbico, the Proto X quadcopter is available right now from its retailer, Tower Hobbies, if you want to try it out for yourself.

As mentioned by Dennis above, please see my review about how to use a larger Tx (from the Hubsan X4 V2) with it. :)

Ryan Becker

There is a review on Youtube that show a guy using the Hubsan X4 Controller with this quad and it will do all the tricks. It is also a much more reasonably sized controller.

Dennis Schmalzel

I think that is really cool.

Perhaps if they made the controller big enough that it could also be used as a carrying case for the tiny quad copter, it would make the controller big enough to handle more comfortably? (just thinking out loud). :)


Where did I leave that flyswatter?


@BigWarpGuy: That's a pretty danged cool idea. Make a larger controller/carry case. Awesome. I may have to pick up one of these. With the extreme disappointment of the Phantom getting a mind of its own and being lost forever on the very first flight, I'm in the mood for one that doesn't set me back $500!!! Too bad it can't hold my GoPro.


Is this the same Estes that makes model rockets and engines?

Gregg Eshelman

I just got this little bugger tonight.. this is the first quad I've had and it is really fun. Can't wait to try it on a calm day outside.

How do u know when the battery is fully charged

George Cobb

Ryan Becker, thanks for the video on the Estes Proto X. I can make you that carry case if you like. I'd thought I'd try that quad (first one for me) but then figured I'd try the The New Hubsan X4 H107L Improved Version instead, since it has the controller you like, included. Anyway I do like small projects and will be happy to tackle a little carry case, no charge, of course. My email (dee)(ee)(three)(seven)(four)(two)(one)(at)gmail(dot)com. Best, David


does ant one have the written instructions on how to set the gyros on this pronto-x

Jerry McCrite

Had a couple over the last few months.

The brushes wear out in the motors after about 30, crash free flights, and quicker if you crash and the rotors get suddenly stopped.

All in all, I loved it, out of the box, but after re-soldering, salt grain sized connections, while replacing 7 motors so far, I can say I think it needs a lot more work in the design stage, and, less expensive motors (if they're gonna make them so cheap) that you don't have to get mailed in from the UK.

2/5 stars

I just bought this Proto X. After reading the instructions, it says I have to turn on the Proto X before charging. The instruction sheet shows where the off on switch is but not how to move it. Any ideas would be appreciated. Flyboy 70TC

Just bought one. IMPOSSIBLE TO FLY ! Mine just spins around on the kitchen floor, then when I try to get it off the ground, It just takes off to one side and flips over. Trims don't work. I have lots of micro helicopters and they fly fine. Big mistake in buying this.

Scott Blackburn

It does take a lot of practice to fly. If you push left control toward yourself it will land if you've lost control. Practice hovering first.


I have one. Love it. Cat loves it too. 10-15 minutes flight time? Absolutely positively not. 5-7 minutes tops. I have no idea where the 10-15 minutes claimed in the review came from. Maybe 10-15 minutes sitting on a table at 10% throttle.


I'm sorry to report that I found the Proto X Nano extremely difficult to fly. I have been flying radio control aerobatics for over 40 years, but every one of my 20 flights of the Nano resulted in crashing off the walls or a lamp or a piece of furniture. The propellers keep falling off in a crash. The last crash trashed the electrical system and when I give the Nano throttle now, it just flops upside down.

I am disappointed in this product. It is definitely not "easy to fly" as stated on the box. My friend suggested that I should have bought a more expensive quadcopter (about $150) with a proper stability program in it. I think I will do that.


My fienc and I bought our proto X nanos about a month ago. we were a little apprehensive at first when we first took them out of the boxes because of their small size. but after watching a quick demo flight by the salesperson at our local hobby store we knew that we had to at least get them and try them.

at first it was slightly difficult to fly but after learning how to tweak them with the trim buttons on the controllers we were able to control them quite well. now that we've had them for some time and have flown them quite often we have nothing but good things to say about them. some of the reviews that I have read have stated that people don't like the fact the propellers come off easily. I personally am glad that they come off easily because it keeps them from breaking. the first few times that we would have propellers come off when we put them back on we noticed that the devices would not fly right if at all. after almost giving up on them my fiance discovered that on each propeller there is a tiny letter either A or B and where the motors are on the device they're also letters A & Bas long as you put the right color propeller on the right matching letter the device will fly just fine.

I am a little bit more aggressive with my freinds and she isand as a result needless to say my little Nano has taken some pretty hard hits. it has also taken many hits from our kittens and ferrets because I have found it quite entertaining to chase them around the room. but my little Nano has not missed a beat. about a week ago I was flying around our bedroom we had the air conditioner running and the wind from the vent caught my nano and blew it across the room and into a wall. the problem was there was a bowl of water for the cats sitting on the floor right underneath where the Nano hit the wall and it fell into the water bowl.

I thought for sure that was the end of my toy. I took it out of the water bowl and was immediately able to start flying again. about four nights ago I got brave and decided to take my nano flying outside after dark. after zipping it back and forth across the yard and being impressed by its high speeds I failed to realize that I was right above the roof of the houseas the light started blinking indicating that the battery was dying by the time I realized I was over the roof the battery had died and my nano fell on the roof. I had to wait until the next morning before I was able to get something to climb up on and get it down. the problem was it rained that night causing my nano to have to stay outside on the roof in the rain.

the next morning I decided to get it down not expecting it to work but once again I charged it up and it flies just fine. apparently they are not only durable for crashing they are apparently water resistant. I personally feel that someone who has an interest in this type of entertainment could not find anything any better to spend $39.95 on.

these little gadgets have my highest praiseI feel they are well put together well designed and are totally worth the money in every way. so to the designers of proto X my hat is off to you I hope you will continue your fine work and continue to bring this type of entertainment to me and the millions of other people like me that enjoy the world of RC modeling. way to go guys!!!
