Nearer Have a look at the Bee35
At first look, the Bee35 stands out with its sturdy design and has loads of room for putting in electronics. It’s a comparatively massive 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 digicam.
It’s significantly bigger than small cinewhoops I’ve been reviewing lately such because the BetaFPV Pavo20 (on the suitable). However not like 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 may mount the LiPo battery facet manner (rest room tank mounting), or the normal manner (entrance to again) with this body. You may 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 significantly recognize. To entry the FC and VTX contained in the body, you simply have to take away 4 screws on the underside.
I’ve the Analog model, however the Bee35 can also be suitable with the DJI O3 Air Unit (simply requires completely different 3D printed digicam spacers).
Exterior USB Entry
The Bee35 excels in user-friendly design. A standout characteristic is the exterior USB port, permitting straightforward connection to the flight controller. This considerate design saves time and trouble throughout setup and changes.

Design and Construct
They’re utilizing their newest finances F405 Mini Stack, which is uncommon for a cinewhoop. Most cinewhoops as of late would use an AIO board as a result of restricted house (ESC and FC constructed on the identical PCB). By utilizing their very own separate FC and ESC boards, it ought to supply higher reliability as properly conserving price to a minimal.
As you may see, the body helps a variety of elements and presents loads of house for numerous setups. The mounting choices for the flight controller are versatile, accommodating stacks of various sizes. Nevertheless, the battery strap is stretching for battery sizes they suggest, it might 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 useful, their print high quality has room for enchancment.
GPS mount can also be included. It’s detachable with the aptitude for tilt angle adjustment. Nevertheless it solely helps micro measurement GPS modules that measure round 12.5×16.0mm. I consider they provide completely different sizes however you would possibly have to ask their help for the design information and print them your self.

Energy Consumption
The LED strip consumes round 3W of energy (about 0.12A for a 6S battery), which suggests it received’t have a noticeable impact on flight efficiency or flight time.
Flight Efficiency
The PID and filters are already arrange on the manufacturing unit. The tune is configured by coming into the numbers immediately, somewhat than utilizing sliders, which is an attention-grabbing strategy. The flight efficiency is sort 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.

It binds nice with my ELRS Radio which has V3.3 firmware, which suggests the receiver additionally has V3 firmware.
You too can re-flash the receiver firmware with your individual bind phrase.
See my tutorial for extra element how one can bind ExpressLRS receivers: https://oscarliang.com/bind-expresslrs-receivers/
