Comparison DJI Tello Boost Combo vs RYZE Tello

The frequency of the radio channel used to transmit the video stream from the camera on board the drone to the receiving device: smartphone or tablet, control panel or pilot’s video glasses. The most common frequencies are 2.4 GHz and 5.8 GHz; video data transmission at a frequency of 1.2 GHz is less common. This parameter directly affects the quality and stability of the video signal, depending on environmental conditions, as well as accompanying interference from other devices. Thus, for receiving video from FPV drones, the most preferable frequency is 5.8 GHz, which is due to a wide selection of channels and high data transfer rates.

The number of batteries for the drone itself, supplied in the kit.

Most modern drones use a single battery; accordingly, the presence of several batteries in the kit usually means the ability to quickly change them. This allows you to extend the operating time without recharging the batteries: when the energy reserve is exhausted, it is enough to replace the dead battery with a fresh one. At the same time, there are quadcopters that require several batteries at once; this feature is directly indicated in the specifications (see below), and such models are usually equipped with the minimum set of batteries necessary for operation. However, there are exceptions — for example, a model for two batteries can be supplied immediately with 8 or even 10 power supplies. These nuances should be clarified separately.
