If you’re not involved in the world of remote controlled vehicles, you may not know there’s a difference between “toy” and “hobby” grade hardware. For those in the RC community, a toy is the kind of thing you’ll find at a big box store: cheap, works OK, but lacking in features and build quality. On the other hand, hobby hardware is generally considered to be of higher quality and performance, as well as being more modular. At the risk of oversimplification: if you bought it ready to go from a store it’s probably a toy, and if you built it from parts it would generally be considered hobby grade.
But with the rock bottom prices of toy quadcopters, that line in the sand is having a harder time than ever holding some in the community back. The mashup of toy and hobby grade components is giving rise to the concept of “frankendrones” that combine the low cost of toy hardware with key upgrades from the hobby realm. Quadcopter blogger [garagedrone] has posted a roundup of modifications made to the Bayangtoys X16, a $99 quadcopter which is becoming popular in the scene.
Some of the modifications are easy enough for anyone to do. Swapping out the original propellers for ones meant for the DJI Phantom 3 increases performance and doesn’t even require tools. If you want to go a bit further down the rabbit hole, you can cut off the X16’s battery connector and replace it with a standard XT60. That lets you use standard 3S LiPo batteries, which are cheaper and higher capacity than the proprietary ones the toy shipped with.
If you have a 3D printer, there are also a number of upgraded parts you can print which will bolt right onto the X16. Payload adapters, landing gear, and GoPro mounts are all just a few clicks (and some filament) away. This library of 3D printable parts is made possible in part because the X16’s frame is itself a clone of another toy quadcopter, the popular Syma X8C. So anything listed as compatible with the Syma X8C should work with the X16 (and vice versa).
Finally, if you really want to take the X16 to the next level, you can swap out the flight controller with an open source and better supported hobby grade model. Some of these flight controllers and associated new receivers can end up costing about half as much as the X16 did to begin with, but the vast improvement in performance and capability should more than make up for the cost.
We’ve covered previous efforts to increase the performance of low cost quadcopters in the past, as well as builds that put frugality front and center. It seems that no matter what your budget is a screaming angel of death is available if you want it.
