A:AnswerAbout 300 feet with no obstructions. It works based on a wifi access point in the drone, and your tablet's/phone's wifi client.
10-13 min, so the trio of batteries in the combo are helpful.
We have tried several small drones, and this one by far is the best we have experienced at the low price point.
A:AnswerComes with one set of extra props, three batteries, and a charger that will hold 3 batteries. (Just a note, the charger will only charge one at a time, not all three at the same time).
A:AnswerThese type self-discharge to prevent leaking and overcharging. Also, low tech batt discharge when they are making contact with metal (charging terminals). Try taking them out after fully charging, they will still discharge but not as quick.
A:AnswerHi Marylin first make sure that the phone he's going to connect it to can work with the app that needs to be downloaded into inorder to control the drone with the cell using a virtual control which works great on my IPOD 6th GEN which wasn't on the list for compatible cell phones in the IOS & Android list. But after experimenting with the ipod it works great. As far as connecting to wifi, it has a built in ssid ( wifi name of connection) that'll show up in your setting and wifi connection. Then you'll see TELLO to connect to. So at my home it connects me to tello and disconnect from the home wifi. Almost like a bluetooth connection. I've heard if using a regular cell place it in airplane mode and should work. But like always look deeper into this. Hope this helps.
A:AnswerI am just another customer, but I have a few tellos. I would check that the propellers are not bent, or the propellers guards are not bent up, making contact with blade. If all that looks fine, use the forked end of the small shiny tool to wedge between the top of the motor, and bottom of prop. They will slide off, and push back on very easily. Just note which ones are CW, and CCW. I have found that I will occasionally pick up a loose piece of long hair, and it will wrap around the motor shaft under the propellers. But with the propellers off, it's easy to slide the tiny "roll" of hair up and off of the shaft. After a few hundred flights, the motors will start to fail causing spins and landings. They are available online fairly cheap, although it is a bit of a project to replace them. I'd recommend watching a couple YouTube videos on the task. Hope I could help a bit, those are the only problems I have ran into with the few I own these past few years.
A:AnswerIf the drone gets out of range it will land. If you watch the drone when it begins to reach its range limit it will start to correct its self and you can bring it back before it is to far out of its range limit.
A:AnswerBest Buy carries the extra props in many stores. Amazon also has Ryze props; as well as aftermarket, multi colored props of all kinds. A simple search of "Ryze Tello Props" should get you many results.
A:AnswerCoreless
Coreless motors have brushes and commutators, and will work with normal speed controls.
Brushless motors do away with the brushes and commutator, they need special speed controls to handle the switching that is normally performed by the brushes and comm.
