Nearer Take a look at the Bee35
At first look, the Bee35 stands out with its strong design and has loads of room for putting in electronics. It’s a comparatively giant cinewhoop, highly effective sufficient to hold a full-size GoPro Hero 12 or DJI Motion 4. It comes with a 3D printed mount for securing an motion digital camera.
It’s significantly bigger than small cinewhoops I’ve been reviewing lately such because the BetaFPV Pavo20 (on the appropriate). However in contrast to the Bee35, the Pavo20 isn’t actually designed to hold something in any respect other than the O3, that’s why they’re so compact.
You possibly can mount the LiPo battery aspect method (rest room tank mounting), or the standard method (entrance to again) with this body. You possibly can unscrew the highest plate and rotate it round, which lets you wrap across the battery strap in a unique orientation.
The body’s construction is designed for ease of entry and upkeep, a attribute I notably recognize. To entry the FC and VTX contained in the body, you simply must take away 4 screws on the underside.
I’ve the Analog model, however the Bee35 can also be appropriate with the DJI O3 Air Unit (simply requires totally different 3D printed digital camera spacers).
Exterior USB Entry
The Bee35 excels in user-friendly design. A standout characteristic is the exterior USB port, permitting simple connection to the flight controller. This considerate design saves time and trouble throughout setup and changes.
The exterior USB port is definitely an extension from the USB port on the FC. That is the primary time I’ve seen this design in a BNF, a really progressive thought.
Design and Construct
They’re utilizing their newest price range F405 Mini Stack, which is uncommon for a cinewhoop. Most cinewhoops as of late would use an AIO board because of the restricted area (ESC and FC constructed on the identical PCB). Through the use of their very own separate FC and ESC boards, it ought to provide higher reliability as nicely protecting price to a minimal.
As you’ll be able to see, the body helps a variety of elements and provides loads of area for varied setups. The mounting choices for the flight controller are versatile, accommodating stacks of various sizes. Nonetheless, the battery strap is stretching for battery sizes they suggest, it could be higher if it was 25cm lengthy as a substitute of 22cm.
3D Printed Equipment
The 3D printed antenna mount on the rear is flexible, it may be used for various setup together with 2.4GHz and 900Mhz T-style antennas, in addition to analog VTX and DJI Air Unit. Whereas these 3D printed components are completely purposeful, their print high quality has room for enchancment.
GPS mount can also be included. It’s detachable with the potential for tilt angle adjustment. Nonetheless it solely helps micro measurement GPS modules that measure round 12.5×16.0mm. I imagine they provide totally different sizes however you may must ask their help for the design recordsdata and print them your self.

For many who favor guide management, a brief press on the LED controller’s button cycles by the accessible LED modes.
You can even use the SpeedyBee app for configuration. The app detects the Meteor package upon drone power-up, permitting for straightforward switching between varied lighting modes.
Energy Consumption
The LED strip consumes round 3W of energy (about 0.12A for a 6S battery), which implies it gained’t have a noticeable impact on flight efficiency or flight time.
Flight Efficiency
The PID and filters are already arrange on the manufacturing facility. The tune is configured by getting into the numbers straight, quite than utilizing sliders, which is an fascinating method. The flight efficiency is kind of good for a pre-built mannequin; there’s actually nothing to complain about.
When flying with out the GoPro, the Bee35 hovers at round 27% throttle, which feels highly effective for a big cinewhoop of this measurement. There’s no noticeable bounce-back or prop wash when performing flips and rolls, demonstrating the effectiveness of the inventory tune.
Utilizing a 6S 1100mAh LiPo battery, you’ll be able to count on round 6 to 7 minutes of flight time (cruising with out GoPro), which is longer than the common for cinewhoops on this class.
