I beforehand reviewed the Walksnail Moonlight digital camera, a competitor to the DJI O3 Air Unit. Now, we have now the primary commercially obtainable cinewhoop geared up with the Moonlight—the Caddx GoFilm20 Cinewhoop. Let’s dive deep into what this drone provides and if it actually lives as much as its expectations.

Construct and Design
The Caddx GoFilm20 Cinewhoop stands out with its light-weight and compact design, weighing in at simply round 121 grams. This makes it attainable to maintain the entire weight beneath 250 grams with a 4S 650mAh battery (usually weighs round 75g), an important issue for these acutely aware about drone laws.
For context, right here’s a dimension comparability with the BetaFPV Pavo 20.
On the coronary heart of the GoFilm20 is the Walksnail Moonlight digital camera. This 4K digital camera comes with an ND filter and is mounted on an anti-vibration mount on the entrance of the drone, aiming to reduce shaky footage. The power to alter ND filters simply is a plus for adapting to totally different lighting circumstances shortly.
The body is designed across the Walksnail Moonlight digital camera which helps 4K 60fps recording, and provides 1080p video feed again to your Walksnail goggles. On the underside there’s a big lower out for airflow and cooling.
From a design perspective, the GoFilm20 is remarkably user-friendly. Key elements like firmware replace connectors, the SD card slot, and management buttons are all readily accessible, which I drastically recognize. This considerate format enhances the general person expertise, particularly when within the discipline.
The drone options 1303 6000KV motors paired with tri-blade propellers enclosed inside protecting ducts. This setup enhances security, minimizing dangers throughout indoor flights or shut encounters with obstacles.
One minor gripe I’ve is the continued use of a micro USB connector for the flight controller. In an period the place USB-C is turning into commonplace as a result of its robustness and ease of use, this seems like a missed alternative for modernization. Nonetheless, the silver lining is the position of the micro USB port, which is strategically positioned for straightforward entry.
The video transmitter and receiver antennas are thoughtfully secured on a 3D printed mount on the drone’s rear, which provides a layer of sturdiness and stability to the setup.
The all-in-one (AIO) flight controller integrates an ExpressLRS receiver (UART primarily based), simplifying the setup. The drone’s meeting is user-friendly, making disassembly and repairs comparatively simple—there are solely 5 screws it’s good to take away.
Right here’s an in depth up of the flight controller board.
Flight Efficiency
Flying the GoFilm20 Cinewhoop is really a delight. Its agility and responsiveness make it a pleasure to pilot. The drone handles properly, able to executing nimble maneuvers and sustaining secure flight, even when navigating near obstacles.
Nonetheless, I seen some propwash and vibration with the inventory PID tune. Luckily, Gyroflow is impressively efficient at eliminating these shakes and jello, guaranteeing that after the footage is stabilized in post-production, these minor points are hardly noticeable. Usually, these shakes aren’t a serious concern as a result of with a cinewhoop, you’re usually cruising easily slightly than performing aggressive acrobatics. With some further PID and filter tuning although, I’m assured that propwash and vibration will be additional minimized. Should you’d like me to fine-tune this quad and share the settings, please drop a request within the feedback.
The GoFilm20 provides 5 minutes of flight time with a 4S 650mAh LiPo battery and about three to 4 minutes with a 4S 450mAh. That is pretty commonplace for 2-inch cinewhoops, offering respectable flight time for a satisfying session.
Relating to picture high quality, the Moonlight digital camera impresses with its 4K 60fps video functionality and assist for Gyroflow stabilization. Nonetheless, to be fully trustworthy, whereas the picture high quality is kind of good, it nonetheless barely lags behind the DJI O3 Air Unit with the present firmware. I hope they will enhance it in future updates as a result of I do consider the Moonlight has potential. Regardless of this, being able to file in 4K in such a compact drone is a big benefit, and the general design of the GoFilm20 is commendable for its integration of high-level options in a streamlined package deal.
Setup
Contained in the field, you’ll discover the official guide, which provides detailed steering for getting began with the drone.
Out of the field, the drone arrives pre-configured with Betaflight, which was surprisingly properly arrange. I discovered that solely minor tweaks had been needed for the maiden flight. It’s value noting that whereas the PID and Filters have been barely adjusted, primarily based on my testing, there appears to be some room for enchancment.
The drone was loaded with Betaflight 4.4.3, and the FC board goal is BETAFLIGHTF4. You may get the unique CLI dump/diff right here.
Changes I Made in Betaflight:
- Configuration Tab: Allow ESC Beacon to assist find the drone in case of a crash.
- Preset Tab: Apply the ExpressLRS preset appropriate to your packet fee to optimize smoothness of your inputs
- PID Tuning Tab: Regulate Charges/Expo in accordance with your flying model and preferences.
- Modes Tab: Assign an arm swap.
Binding the Receiver:
The GoFilm20’s receiver is a Happymodel EP1/2 2.4GHz, pre-loaded with firmware model 3.0.1. To bind the receiver, comply with the information obtainable right here: https://oscarliang.com/bind-expresslrs-receivers/
ESC:
The built-in ESC within the AIO Flight Controller is already pre-flashed with Bluejay firmware (0.19, 48KHz, goal F-H-40), so there’s no want for added flashing.
Last Ideas
The Caddx GoFilm20 Cinewhoop is right for anybody seeking to seize high-quality video in tighter areas the place bigger drones wouldn’t dare to fly. Its ducted propellers and compact dimension permit it to slide by means of tighter gaps safely, making it good for indoor shoots or carefully packed environments. Furthermore, its comparatively quiet in comparison with bigger FPV drones, making it much less intrusive, best for locations the place noise might be a priority. Its integration with the Walksnail system, ease of use, and strong construct high quality make it a compelling alternative for each seasoned pilots and newcomers to the drone cinematography scene. Nonetheless, it’s not made for crashing as a result of skinny prop guards.
The GoFilm20 is accessible for buy from the next distributors:
In conclusion, should you’re out there for a small, succesful HD drone that mixes portability with respectable filming capabilities, the Caddx GoFilm20 Cinewhoop is value contemplating. Its efficiency and have set present nice worth, promising exhilarating flying and filming experiences proper out of the field.
