This is another very recommended drone which is under $100 dollars. This drone has gotten 5 star reviews and from USA toys which is one of the trusted manufacturer of cool toys. This is one of the latest version of UDI 818A drone with excellent features. This drone is one a huge discount with free shipping. Are you considering this drone as your best drones with camera under $100? Let’s get into the features.

Since repairs are as easy as soldering a couple motors and the flight controller has proven reliable and capable, people have developed a few nice modifications for it. Modifications such as a chassis swap with lighter and more durable materials are fairly easy, even for those without electronics skills, and yield longer flight times as well as further improved handling.
While it does not have a whole lot of features, Orientation mode is pretty useful. It ensures that your drone stays within connection range and won’t fly off on you. The LED lights are great for night flying, especially when the battery is low and you need to ground it quickly. It can do the basic flip approximately 1 meter off the ground to ensure it doesn’t collide.
For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position.  ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings.
The Altair AA108 is durably built and will not break easily. You can count on a solid flight time of around 10 minutes, a bit less when you’re running it FPV. However the 720p camera really works well and connects to your phone through WiFi. It’s easy to fly because it has 3 flight modes, 1 beginner, 2 intermediate and 3 advanced mode. It also has Altitude Hold which allows you to take your thumb off the control and the drone holds it’s own altitude, making it very stable because it’s not bouncing up and down as you try to maintain altitude!
This guide will walk you through some of the features and capabilities you can expect to find in a drone under $100, in addition to some more general considerations when comparing UAVs. We also recommend several models, so you can spend more time learning to navigate around trees and less time worrying about finding a drone that matches your needs.
Most drones are pretty easy to fly, but the controls will be slightly different depending on what kind of drone you get. Camera drones are the easiest drones to fly, while toy drones can be harder (because of their lack of sensors and flying aids). To fly a camera drone, people usually use a controller with their smartphone attached to it. The smartphone will let you see a live video feed and all of the most important flight data you need. Some drones like the DJI Mavic Air, DJI Spark, and Yuneec breeze allow you to fly just using your smartphone.
It can take aerial shots with the altitude hold function, accessed by releasing the throttle. The drone hovers in place to get the shot. If you’re first starting out, you can operate it in headless mode to get a better idea of what it can do. It has a one-key return, and you can even perform aerial tricks and flips once you’ve mastered necessary controls.
Flight is smooth on this drone, with an impressive climb and turning rates that meet the demands of even expert fliers. You can count on the stability of the X400W when in windy conditions – the six-axis gyros do a good job maintaining hovering with lateral winds. You can access the FPV stream on your smartphone via a WiFi connection. With the dedicated app, you can activate the camera and record sharp videos and images. It is important to note that the HD 720p camera is primarily for delivering an FPV live stream, rather than shooting pictures and videos. You can also connect this drone with a 3D VR headset if you want to enjoy a 100% immersive FPV flying experience. 
On the other hand, ATTI is a partially different tool, whereby the quadcopter uses other techniques and not necessarily external sensors to firmly hold the drone in correct altitude and orientation. ATTI allows the drone to hover in place, as well as to gently drift around while being pushed by the wind. Some drones also have GPS which offers great precision and coordination during flight.
For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position.  ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings.

There are various factors you should take note of when shopping for these particular machines. First, you need to check the control operating system to ensure that it’s easy and manageable to use. Basically, there are 3 main control functions you can choose from which include OPTI, ATTI, and GPS, though they all help in flight-stabilization and assistance they tend to do it in slightly different ways.
