A B C of the Drone Industry


I wanted to get into the subject about the different terminology and technical terms when you are starting out for the first time with drone racing. For example texting a friend, you have different ways like LOL-laugh out loud. So a new comer to this industry you need to know what you're talking about because it's like a second language to all people in this industry. So i did do some research and i came up with the ones i think will be beneficial to you weather your racing quads or doing free style or operating the radio control. Here is the terminology, abbreviations related! So don’t feel like you have to straight away know all these terms because myself am still learning. A good way to learn these is print out this list i have provided and stick them on the back of your toilet door and this way you will be able to memorise them one by one. I know there would be more of these terminology’. But if you keen by all means go for it. I hope this can be use full to many of you. I think whats really important is when you start out things can be quit an over load with all this info plus I felt like that when i started. I would learn a couple a day and concentrate practicing your flight skill’s with a simulator. Head to my website and i have some video’s on some sims and they are for free to download. If you want for need help simply message me and i will be more then happy to help. Plus subscribe to my website and you will be able to leave a comment and i will message you back. So remember you don’t have to know all these. But i wish you all the best and have fun
