It’s been quiet these last few weeks in drone news. Some members of the commercial community are performing missions, while others are waiting on the results of the FAA’s appeal to the NTSB. There is no denying that drones are getting larger as an industry though. Even Facebook has jumped into the fray, not for drones to deliver real world pokes, but to provide internet access in remote areas.
One of the high points in the news was an octocopter operator’s discovery of 2500 year old rock drawings, or petroglyphs in the Utah desert. While exploring a known archeological site, Bill Clary of GotAerial LLC flew his octocopter up to a cliff face. The rock formation would have made rappelling down the face difficult at best. He found an amazing collection of petroglyphs which he documented in this video. While the authenticity of the petroglyphs hasn’t been proven yet, they appear to date back to the Basketmaker people who lived in the area from approximately 500 BC through 860AD.

Drone, Drone of my own: Getting started
Getting started with drones SHOULD be easier than it is. As with any complex endeavor, there are some common pitfalls which often snag enthusiasts. The biggest one I see is a new pilot buying and building an expensive model – be it for sport, aerial photography, FPV, or fully autonomous – without learning how to fly first. This is a sure-fire recipe for disaster. Just about every autonomous model falls back to radio control when problems arise. FPV models can and do have video failures, so knowing how to fly line of sight is essential. Think of it as learning how to drive. You wouldn’t want to learn on Corvette or a Rolls-Royce. The same applies to drones. Don’t learn with an octocopter, or with $2000 USD of camera equipment hanging off your aerial photography rig.
Just choosing a first quad to learn with can be a daunting task. Back in the early 1990’s, I worked in a hobby shop. There were only a handful of large R/C manufacturers back then. Most of them were based in the US, Europe, and Japan. With the rise of China and the global economy, there are now hundreds of manufacturers and distributors of drones and RC models. This leads to the often seen “clone of a clone of a clone” situation we’ve come to recognize with the Arduino and any popular electronic device. But which models are of decent quality, and which are junk? The easiest way to get a good answer is to seek the advice of others.
From my own experience, I’ve found a specific quad to be pretty good for learning to fly. It doesn’t hurt that it’s also one of the cheapest out there. The Syma X1 is a pretty darn good quad to learn with. The Syma appears to be a copy of the Blade MQX quadcopter – however Syma fixed a few flight issues the MQX suffered from. You can find the Syma at Amazon and other online retailers for around $30 USD. The X1 is a brushed quad, which means the motors use carbon brushes to transfer power to the coils. Most larger quads are brushless. Don’t let the older technology fool you. Brushed motors are just fine in this application. However, the one part of the X1 I don’t really like is the transmitter. While it does sport an LCD display, the sticks and overall action feel cheap. They had to save money somewhere. Even with that shortcoming, the Syma transmitter is fine to learn with. A real nicety is that the X1 can be paired with the very hackable Turnigy 9x series transmitters.
Don’t forget to check the mode of the transmitter when ordering. Mode 1/Mode 2 refers to the layout of the controls on the sticks. Asia and Europe tend to use Mode 1, with the throttle and aileron on the right stick. North America uses Mode 2, where throttle and rudder are on the left stick. Since throttle control doesn’t use a centering spring, this is a mechanical change, not just a software remap of functions. One mode isn’t any easier than the other to fly, but flying with friends is more fun when your radio has the same functions as theirs.
While I don’t plan to make Droning On a tutorial on learning to fly – there are plenty of great quality tutorials out there - I do want to help out with a few tips.
- If you you’re about to crash, chop the throttle. The X1 is so light that impacts usually result in no damage. Ensuring the motors are off when that impact happens will save your propellers, gears and motors.
- Try to fly over grass or dirt, not concrete. Some tutorials will tell you to skid the quad around on the ground while learning. The skidding is a throwback to R/C helicopter training. With small quads like the X1, it’s better to get a couple of feet off the ground and out of ground effect turbulence.
- If you feel like you’re losing control, let the sticks go – the gyroscopes and accelerometers on the X1 will often bring it back to a level hover.
- Keep the back of the drone facing you. In that orientation the drone will follow the movements of the stick. When you’re comfortable with that try out other orientations.
- “Nose in” is the hardest orientation to master, as your left is the quadcopter’s right. The quadcopter will mirror your stick movements.
- Have fun! Seriously – it’s easy to get frustrated and stressed out when learning . If that happens take a breather, and try to remember that even if it were to fly away, the X1 is only $30 to replace.
One of my favorite aspects of the internet has always been the collaboration. Like ham radio operators, R/C and drone enthusiasts were early adopters of the internet. Where news and information would only come once a month through magazines, it’s now available instantly online. Usenet provided early access through the rec.models.rc newsgroup tree. As the web came of age, much of the conversation moved to forum based websites. Some of the oldest and richest resources are the R/C forums. The best example of this would be RC Groups. Created as part of the Ezone, an electric RC magazine dating back to 1995, RC Groups has sections for just about every aspect of the hobby. The Multirotor, FPV, Aerial Photography, UAV, and DIY Electronics sections will be of interest to Hackaday readers.
Here are a few other RC and drone oriented forums:
- RC Universe, general RC forum similar to RC Groups.
- FPV Labs covers first person video enthusiasts.
- multirotorforums covers all things multirotor – from tricopters to octos and beyond.
- AP Landing covers the aerial photography folks.
Note that this isn’t an exhaustive list. I tried to cover a few of the big sites. If you know of any that I’ve missed, please throw them into the comments.
The problem with most forums is finding information. Sure they have searches, but they usually leave quite a bit to be desired. As an example the main Syma X1 thread on RC groups is currently over 5200 posts spanning 348 pages. Topics meander, flame wars are waged, and post sizes get out of hand. If statistics are to be believed, RC Groups averages around 20,000 active users at any given time. It’s understandable how even an army of mods would have a hard time keeping up.
There are plenty of non-forum based drone information sites. 3D Robotics maintains a community site at DiyDrones which is chock full of forum and blog information. Instructables has a number of drone entries. The Drone section at Hackaday.io is still looking pretty lean – though we’re hoping you’ll help change that in the near future.
That about wraps it up for this edition of Droning On!
