Drones come in all shapes and size, and [Kedar Nimbalkar] was wondering if the guts of a tiny Cheerson CX-10 nano-drone could take off with a larger body, leading to an interesting brain transplant experiment.
For his test, [Kedar] acquired a CX-10 and the body of a larger Syma X5SW drone. After gutting the CX-10 for its LiPo battery and circuit board, which features an STM32 ARM-core MCU, a 6-axis IMU and the wireless transmitter, [Kedar] studied the datasheet of the onboard SQ2310ES driver MOSFETs. He figured that with a maximum continuous current rating of 6A, they would probably be able to cope with the higher load of the slightly larger motors of the X5SW body. They also didn’t seem to overheat, so he just installed the board into the new body as-is and wired up the motors.
The first test flights didn’t go well. The CX-10 brain was slightly confused with its new body, which additionally seemed to be flawed with a few mechanical bugs. After stabilizing the wobbly propeller shafts, [Kedar] was able to fly the upsized nano-drone quite well. Naturally, it doesn’t fly very stable with the stock PID settings making it wish for the return of its youthful slenderness, but it’s a start.
That’s also where our readers come in: Custom firmwares on the CX-10 are nothing new, so have you been flying a scavenged CX-10 PCB in anything else than its original shell? Let us know in the comments! Enjoy the video below where [Kedar] explains and flys his frankendrone:
