Construct High quality and Design
The Bee25 drone boasts a glossy design with a clear tinted plastic body that homes its elements. This offers the Bee25 a novel and trendy aesthetic, whereas additionally permitting you to see the internals, particularly these stunning LEDs across the body.
The built-in Meteor LEDs not solely add visible enchantment however are additionally purposeful. They show the drone’s standing, corresponding to whether or not it’s armed or in fail-safe mode, and assist with finding the drone in low-light situations. This function, together with the flexibility to manage the LEDs by means of Betaflight or the SpeedyBee app, provides one other layer of practicality and usefulness.
Regardless of the light-weight supplies, the Bee25 feels sturdy. SpeedyBee has applied good design selections to guard delicate elements, such because the hard-mounted XT30 connector and protecting housing for the GPS. Nevertheless, my evaluate unit didn’t include a GPS module, so I couldn’t check the Rescue mode. Moreover, the easy-access USB-C port on the flight controller makes altering the drone’s settings rather more handy.
Weighing round 165g with out the battery, the Bee25 is designed to remain below the 250g restrict with a appropriate 4S battery. That is vital for complying with drone laws in some areas. When you’re including the DJI O3 Air Unit, be aware of the battery weight to remain inside this restrict. The most important battery you should utilize to stay below 250g is a 4S 650mAh, which brings the overall weight to round 248g.
The elastic battery band, although unconventional, works surprisingly effectively to safe batteries of assorted sizes. A minor challenge arises with longer batteries (over 60mm), which can have hassle becoming correctly as a result of fastened XT30 connector placement. You may work round this by rotating the mounting brackets to suit the battery sideways. Whereas a small inconvenience, it’s price noting for those who plan to make use of bigger batteries.
Made For DJI O3
The Bee25 is particularly designed to accommodate the DJI O3 Air Unit, although my evaluate unit didn’t include one, so I needed to set up my very own. Luckily, the set up course of is simple. The modular digicam mount for the O3 might sound a bit complicated initially in comparison with minimalist designs just like the BetaFPV Pavo20 Professional, but it surely’s effectively thought-out. It offers wonderful safety for the O3 Air Unit, which is vital for sturdiness and reliability.
Whereas the modular system requires a bit extra effort to put in, detailed directions can be found on SpeedyBee’s web site, making the method simpler. It’s a one-time activity, and as soon as put in, the modular design makes accessing the microSD card and USB-C port very handy. Moreover, the drone features a cooling duct built-in into the antenna mount, which helps to forestall the O3 Air Unit from overheating throughout longer flights—a sensible and welcome function.
I did ask SpeedyBee about compatibility with the Walksnail VTX system, however sadly, this mannequin doesn’t help it. For the perfect person expertise, persist with the DJI O3 Air Unit.
Flight Efficiency
The Bee25 flew very well, higher than I anticipated to be sincere, presumably the perfect 2.5inch cinewhoop I’ve flown this 12 months. It’s tuned straight out of the field for cinematic flying, making it simple to seize fluid, stabilized pictures.
The Bee25’s 1404 4600KV motors are highly effective and responsive, providing loads of thrust with out compromising flight stability. Paired with HQ 63mm props, this mixture offers wonderful efficiency for clean, cinematic flying. Even with a big 4S 850mAh LiPo, it nonetheless managed to hover round 25% throttle supplying you with loads of headroom for extra aggressive maneuvers if wanted which is fairly spectacular.
Battery life on the Bee25 is stable. Utilizing a 650mAh 4S battery, I used to be in a position to get about 5.5 minutes of clean, cinematic flying. Once I upgraded to an 850mAh battery, flight time prolonged to about 7.5 minutes.
Whether or not I used to be flying sluggish and regular for cinematic pictures or pushing the drone with extra freestyle maneuvers, it dealt with every part with ease. I did discover some minor prop wash right here and there, however nothing important sufficient to impression the general expertise.
However as a 2.5″ drone, it’s simply as noisy as different cinewhoops of comparable measurement – you’ll draw some consideration for those who’re flying in public areas. It’s a lot louder than even my 3″ open prop drone just like the Sub250 Oasisfly25 I lately reviewed, however that’s to be anticipated for a cinewhoop, one thing try to be conscious of.
Areas for Enchancment
First off, the Bee25 doesn’t include spare propellers, which may very well be inconvenient. You’ll wish to decide some up right here: https://oscarliang.com/product-rw6u.
From a efficiency perspective, I might counsel eradicating the LED strip to save lots of weight, and presumably make the DJI O3 “bare” as effectively utilizing this package: https://oscarliang.com/flywoo-naked-o3-lite-ultra-kit/. This might assist you to use a bigger 4S 850mAh battery whereas nonetheless staying below the 250g weight restrict, supplying you with longer flight occasions and improved efficiency.
GPS isn’t crucial for indoor or close-proximity flying, however for those who’re flying outside or need an added layer of safety, I’d suggest including GPS and organising Rescue Mode. Right here’s a information: https://oscarliang.com/setup-gps-rescue-mode-betaflight/.
The prop guards are light-weight, which makes them much less sturdy. When you anticipate frequent crashes, it’s sensible to choose up some spare body elements to keep away from downtime.
SpeedyBee at all times delivers distinctive designs with cautious consideration to element. Nevertheless, the tendency to design frames that require numerous sorts and sizes of screws could make repairs and upkeep a bit extra sophisticated. They do present two additional screws for every sort, however this complexity won’t enchantment to everybody. When you respect distinctive, aesthetically pleasing frames, SpeedyBee is a superb choice, however for those who choose simplicity, it is probably not your most suitable option. On a constructive notice, I do love that they embrace screwdrivers within the package deal, which is nice for inexperienced persons.
One other limitation is the Bee25’s lack of compatibility with FPV methods outdoors of DJI. If you wish to use one thing just like the Walksnail system, it could require modifications and tinkering, which may very well be a problem for some customers.
