UDI U27 Free Loop Quadcopter Review – Our Favorite Drone!

Let me make this clear up front… I LOVE THIS DRONE! Of all my drones, if I had to choose one to have a few minutes of fun flying – it would be this one. When I want to teach a drone newbie how to fly, I grab my UDI U27. It is super easy to control, yet it is incredibly responsive. It is easy to launch, easy to hover, and incredibly nimble.

If you are new to quadcopters and want a forgiving drone to learn on, one that will take some abuse and keep flying- this is it!

Build Quality

I've done mostly indoor flying with this little guy, which means it has had many one-on-one encounters with furniture, bookcases, doors, windows, etc. Despite all the bumps, bangs, and dings – it still flies like new. I did manage to snap one of the supports on one of the prop guards, but after a little super glue – you'd never know it!

Battery Life

I average around 6-7 minutes on a full charge. It can go a little longer depending how fast you are pushing it. It might be my imagination, but flying upside down seems to use a little extra battery power.

Regardless, do yourself a favor and [easyazon_link identifier=”B00ZZ55YC4″ locale=”US” tag=”blueclsolut02-20″]buy an extra battery[/easyazon_link]. They go for less than $10. This drone is so fun to fly, you definitely will not be ready to be done after just 7 minutes. Pop a fresh battery in and keep flying!


Man is this thing agile! I can hover, send it flying across the room at full speed, and just about stop it on a dime! It zips around and is super responsive to every command. Flip it upside down and it performs just as well (actually, it seems a little faster!). Start on low speed while you are learning, then turn on high speed to really get some thrills zipping it around at top speed!

It has excellent range indoors, I can fly it through the whole house no problem. I took it to a large gymnasium and was able to fly it around the whole gym (about 40 meters long) without experiencing any loss of signal. It can definitely perform at its advertised range of 40 meters, possibly more!


The UDI U27 will give you incredible value for your dollar. It is a blast to fly and it will hold up well to any abuse you dish out. I plan to fly this thing until it falls apart, which at the rate it is going – will take a good long while!

Other Notes

[easyazon_image align=”center” height=”500″ identifier=”B00XJ0I1WW” locale=”US” src=”http://www.lemondrone.com/wp-content/uploads/2016/07/419wYllRoLL.jpg” tag=”blueclsolut02-20″ width=”500″]

I was super impressed with how well the drone knows whether it is upright or upside down. If you crash it and it lands upside down, no problem, it will happily launch itself from the ground and keep flying upside down. Flip it over using the shoulder buttons on the remote (it doesn't do full 360 degree flips, just 180s – but I am fine with that. Most drones offer flips – but how many can fly upside down?).

As mentioned, when upside down, the drone seems faster to me. However, I feel like it is slightly less nimble. So I suggest flying normal while inside until you get the hang of the controls. If you have the space, flip it upside down and crank it to the high setting for some really fast flying!

If you are at all interested in getting started with flying quadcopters, do yourself a favor and grab an UDI U27, you will not be sorry!

    This is, by far the best quadcopter, especially in this price range. It has good battery life at around 5+ minutes. For this kind of money this is great. I love that this drone can fly upside down! I actually did not know that when I got it and was pleasantly surprised it can do this. I’ve had it for a few months now and I can tell you that it can take a punch since I’ve been playing with it as well as my kid who hits it from time to time.

    I would like to get a quadcopter that can take a beating because my little guy seems in love with them. He’s just 5 going on 6 and I think this would be the best birthday present ever. If this is easy to learn on and it’s pretty solid, then I will give it a go. $40 isn’t that much for the kind of fun this could offer.
