Oscar Liang flags camera shake on HGLRC Draknight O4 drone review
Oscar Liang liked the Draknight O4’s handling, but the camera shake he found makes tight race courses the wrong place to trust it.
The HGLRC Draknight O4 looks built for micro-racing chaos, with a 2-inch toothpick frame, a 93mm wheelbase, and a claimed 56g plus or minus 5g dry weight. Oscar Liang’s May 22 review showed why track suitability matters more than the spec sheet: the quad handles well, but the camera soft mount adds enough jello and vibration to make the image hard to trust when the pace rises.
That flaw lands hardest on tight indoor layouts, short straights, and rapid gate sequences, where pilots need a steady digital feed to judge lines and correct fast. HGLRC markets the Draknight O4 for racing, freestyle, and cinematic flying, and says its shock-absorbing structure should deliver stable visuals and smooth flying. Liang pushed back on that promise, saying the camera soft mounting “just doesn’t seem to work properly.” For a DJI O4 build, that is not a minor blemish. It is the difference between a promising practice quad and a risky competitive choice.
The rest of the package still makes sense on paper. HGLRC pairs the frame with an F411-based 15A AIO, a built-in ELRS 2.4GHz receiver, 1003 10000KV motors, and the DJI O4 Air Unit. DJI lists that air unit at about 8.2g with a 1/2-inch image sensor and 4K/60 capability, which is exactly why tiny builds like this draw so much interest. Liang also said the frame is easy to build and maintain, helped by a top cage that comes off with only four screws, but he noted the flight controller has only two UARTs, leaving no spare UART for GPS without SoftSerial.
That trade-off is what makes the Draknight O4 such a useful test case for racers. Liang’s review put the dry weight at 61.9g without a battery, still firmly in ultralight territory, while HGLRC’s listing put the price at $114.99 and one reseller showed $165.99. A Rotorbuilds build note claimed the DRAKNIGHT O4 provides video feedback without jello, which suggests the frame itself can work when tuned differently. For pilots weighing speed against image quality, the warning is clear: the Draknight O4 has the footprint and the power for micro racing, but the shaky feed is the one flaw that can turn a sharp build into the wrong pick on race day.
