I pretty new to Arduino and I need help to clarify some things. First, I want to make an Arduino controlled RC airplane but I don't know what communication module to use. I did some research and found three options. 1. Hc 12 Bluetooth: It has a decent range of about 1.8km, buy suffers from delay(it can't be used on fast rc cars or airplanes) 2. Nrf24I01: About 850m in open space, uses
2.4ghz which perfect for RC planes but doesn't really work through walls. 3. Lora: has a range of up to 10km but I didn't read on it that much.

So my question is: which one is better to use in a mini uav. I have no problem with mounting an antenna on top of my building. Will any of these work or is it better to use a wifi module connected to a modem which gives it internet access so that I can control the plane over the internet.

  • Any standard RC. For long range TBS CrossFire. For standard range (up to 2 km) - any other 2.4 control. Let say Jump[er T16 with any RX. As you new in Arduino I guess you also new in flight controllers SW. So better to start with something already manufactured. Let say legacy (old) ArduPilot was based on Arduino Mega.

  • Can you pls elaborate more. By the way, I'm on a tight budget.

  • i think that HC12 is not a bluetooth module

  • you could use a module that uses the cellular phone network

  • @Brandy, what do you mean: APM is here: github.com/ArduPilot/ardupilot TBS is here: team-blacksheep.com/shop/cat:cat_crossfire#product_listing Any RC things are expensive except toys Jan 9, 2020 at 17:27
