Easy to Operate

This is my first drone. It was easy to use, right off the bat. Took a while to get the GPS working, but when I did the drone performed flawlessly.


Great drone

Easy to assemble and fly. Their customer service is also amazing. Bought this for my son and he loves it. Highly recommend the drone and the company.

Good capability at good cost

Good capability. The features such as "return home" are good. There is a definate learning curve and I'm still not very good at use.

So Easy.... I can fly it.

Reviewed on

I bought this for field work and personal purposes. It is easy to start and fly. I will not lie. There are some nuances that need to be discovered to ensure a problem free initialization and flight. But they aren't a huge problem and the customer service at was prompt and helpful.Nuances1: Turn your phone data off. It may interfere with the video signal from the drone.2: Initialize (connect drone and controller) drone first, then try to link to the app.3: Will not link to a phone with only 2.4GHz WiFi. It will connect to a dual or 5GHz WiFi signals. Check your phone's frequency.4: You can fly this and take pictures/video without connecting to the app. Just insert a Micro SD card in the slot and push the Photo/video button of the controller.See? It's easy to have fun with this drone. And the flight time is much longer than similar sized drones.My only beef is that the battery charging adapter is kind of an afterthought. It only charges from a USB 5v source and takes 5-7 hours. Per battery. And the charger must remain still otherwise it'll disconnect and not charge. So rubberband the 2 together if you're going to charge it in your vehicle's cig lighter/USB port.Have fun and stay away from trees and power lines.

Don’t grab it the blades will cut you

Reviewed on

I did the calibration for it put in on the ground far from my truck it I gave it a little bit of power it took off right and it went straight for my truck I couldn’t stop it I pressed the power off button but didn’t work it flipped over I grabbed it to stop it so I decide to try it again I gave it some power then it went to my truck again picked it up the blades cut my finger. So I would say be careful and don’t touch the blades other than that it is a good drone for what it is the camera is good on it once the drone works it really fun to fly

TheContixo F30 is FANTASTIC

Reviewed on

TheContixo F30 is a wonderful drone. Being new to the drone world I was pleasantly surprised on the ease of use and the great quality of the drone. The drone is at a great price that you can't beat! I would definitely recommend this drone to any level user of drones! A+ in my book!

Beautiful Drone With Wonderful Functions!

Reviewed on

I have recently purchased this drone as a beginner pilot to get more involved in the drone community. Long story short, I am absolutely engrossed in this drone and its functions. I have flown it about once a day for 6 days in which it has never malfunctioned or flown away. Overall, it is a wonderful drone and you should definitely buy as it is by far the best drone under $300.CompetitionA close competitor to the F30 would be the Mavic Mini, whose price is over $400. Most if not all functions on both drones are shockingly similar in drone precision and camera quality. The main functions on both drones is the circling Point of Interest, the Return to Home, the waypoint setting, the follow me setting, and the overall stability. Sadly, while the Mavic Mini does include a 3-axis gimbal, the F30 does not. But I would definitely shave off $100 for the same drone but with no camera gimbal!MotorsAs I have flown my drone, no engines have sputtered out or lost control. The precise stabilization while flying and holding in the air is insurmountable. The quick calculations based on wind speed is wonderful as I have flown it over 10 knots of wind and it stayed relatively stable. Secondly, the brushless motors really do make a difference when coming to noisiness. The drone is mostly quiet and once flown over about 250ft. away, you can't really hear it anymore. Basically, they are great motors!CameraThe camera does have a little color correction it must fix, but overall it is pretty good. The drone does not include a 2 axis or 3 axis gimbal and there is no way to install one. To fix this, I usually just go to Emulsio and let the app do the camera stabilization work for me! Me, my family, and my friends all agree that my drone footage is amazing at how well it records.Remote and AppThe remote for this drone is very nice as it shows the amount of satellites in the area. If you are not connected to over 10 satellites (I think) in your nearby area, you cannot fly. The nice, bright display on the remote is very useful for flying in the night. The app (called Ophelia GPS) shows live feed from the drone's camera and it allows you to start any function (POI, RTH, or follow me). It is also very user friendly as it is easy to set up and use.BatteryThe battery on this drone is relatively good. It has a flight time of around 20-25 minutes depending on whether you record or not (recording and turning on landing lights can run down the battery faster). It takes 6-7 hours to charge and can be charged overnight. I have never heard of any fires or explosions created by the battery, but I would always keep it in an explosive-proof bag just in case. Also, after flying the drone, the battery can get hot/lukewarm. I would highly suggest to have a "cool down" period after flying to not get the battery too hot and explode.FunctionalityOverall, this drone is very nice as a recreational use of flying. You really can't make movies or record professional videos with the F30 (as these "Movie Drones" cost $3,000), as it is merely for fun. One thing I would suggest to all beginner drone flyers out there is to make sure you go onto FAADroneZone and register your drone before flying. You will get a unique registration number for your drone to fend away any lawsuits against you and your drone (that is only if you crash).Lastly, it is a very fun drone to fly and has upscale functions much like the more expensive drones! I have attached a video to show the drone and camera quality! Thanks for reading!

Right out of the box, this product was easy to use and fun to fly. Very intuitive with the remote and iPhone app...I’ve never flow a drone before, this one is super simple...I was recording video and pictures with in 5 minutes of setting up...just one note, the battery takes a long time to charge, get it going early...the flight time is advertised 25+/- minutes
