Body and Sturdiness
Not like most 75mm whoops that rely solely on plastic frames, the AcroBee75 incorporates a mix of carbon fiber and plastic. This design enhances the stiffness of the body, lowering vibrations from the motors, which not solely improves sturdiness but in addition positively impacts flight efficiency. The carbon fiber, which is about 1mm thick, supplies a stable spine with out considerably including to the burden.
Whereas the body is pretty sturdy, after a couple of exhausting crashes, the plastic elements might bend out of form. Thankfully, it’s simple to reshape them by hand. It’s also possible to use a hairdryer to softly warmth the plastic, maintain it in place whereas it cools, making it simpler to revive its authentic form. The carbon fiber, nevertheless, held up flawlessly all through my check flights, which is a promising signal for the long-term sturdiness of the drone.
Elements
At first look, the AcroBee75 seems to be just like its predecessor, but it surely’s full of new {hardware} and now helps 2S enter, giving it extra energy.
The AcroBee75 BLV5 packs numerous tech right into a small kind issue.
One of many standout options is the flight controller, which integrates a VTX with variable energy ranges. It gives 25mW for racing, 100mW for freestyle, and a Good-Max mode that reinforces output as much as 400mW for long-range flying. Utilizing the FPV vary estimator (https://oscarliang.com/js/fpvrange.html), and with a 9dBi patch antenna, you would theoretically obtain a spread of as much as 2km on the 400mW setting beneath excellent circumstances.
A stunning addition is the twin antenna setup on the flight controller, which I haven’t seen earlier than on a whoop. This built-in ExpressLRS range receiver is probably going the primary of its type on a whoop flight controller. One antenna is mounted horizontally, whereas the opposite is positioned vertically within the body, making certain optimum sign reception regardless of the drone’s orientation.
Nevertheless, having a range receiver on a tiny whoop could be overkill since we sometimes don’t fly these small drones lengthy distances. ExpressLRS excels at lengthy vary, even a single antenna receiver would probably suffice for this objective. I hope NewBeeDrone places this flight controller to good use sooner or later, maybe in a micro FPV drone designed particularly for long-range flights.
The FPV digital camera is the Runcam Nano4, housed in NewBeeDrone’s Goober Cover V2, offering a sturdy and compact setup. The motors are Movement 0804 14,000KV, geared up with twin ball bearings, which ought to provide smoother and longer-lasting efficiency in comparison with bushings. The propellers are NewBeeDrone Azi 40mm tri-blades, and also you get an additional set within the field, which is at all times a pleasant contact.
Battery and Weight
The AcroBee75 BLV5 makes use of a 2S LiPo/LiHV battery with an XT30 connector, and contains a light-weight, versatile 3D-printed TPU battery holder. This mount is designed to securely maintain numerous battery sizes in place, even throughout crashes, providing versatility for various flying types.
Nevertheless, the mount is designed for particular battery sizes. The inventory holder is designed for 2S 450mAh batteries, whereas a spare mount included within the package deal suits a 2S 850mAh. The mount is hooked up with 4 screws, so if you wish to change to a distinct battery dimension, you’d should swap out the mount, which is usually a bit inconvenient within the subject. Fortunately, I discovered the bigger 850mAh mount is versatile sufficient to additionally maintain smaller packs like 650mAh or 450mAh batteries while not having to modify mounts, including some comfort.
The AcroBee75 weighs 36.6g with out a battery. With a BetaFPV 2S 450mAh LiPo, the overall weight is 64.5g, and with a Tattu 2S 850mAh, it weighs in at 76.2g.
Indoor and Out of doors Flights
Whereas the AcroBee75 is technically able to flying indoors, its 2S setup makes it fairly highly effective and quick, which might make indoor flights difficult in an average-sized home. Flying a 1S 75mm whoop indoor is fairly exhausting, the additional thrust from 2S means throttle administration can much more tough, particularly for inexperienced persons. If you happen to’re simply beginning out in FPV, I like to recommend getting comfy flying open air earlier than trying indoor flights in tight areas. If indoor flying is your main objective, particularly in smaller areas, you may wish to take into account a 1S whoop just like the Air65 for higher management and ease of use: https://oscarliang.com/betafpv-air65/
In my expertise, the AcroBee75 is extra suited in outside environments. The elevated energy from the 2S battery setup and the 14,000KV motors make it excellent for quick, aggressive flying. It handles bigger maneuvers and fast strikes with ease, making it a enjoyable and versatile flyer. Nevertheless, when you’re primarily flying open air, I’d take into account a ductless micro drone, just like the 2S 3″ quad I beforehand constructed, which tends to be sooner, extra environment friendly, and higher at dealing with wind because of the lack of duct weight. The AcroBee75’s foremost benefit lies in its propeller guards, which add a layer of safety, particularly when flying round individuals or in tighter areas.
Flight Efficiency
The AcroBee75 on 2S is numerous enjoyable to fly. The flight efficiency met my expectations—it’s precisely what you’d need from a 75mm whoop. With a 2S 850mAh battery, it hovers at round 35% throttle, it’s not not overly highly effective and management feels manageable, making it extra beginner-friendly in comparison with different, extra highly effective freestyle-oriented 2S FPV drones. The drone is fairly locked in and responding nicely to stay inputs. I didn’t discover any important bounce-back or extreme propwash.
When it comes to effectivity, I achieved over 8 minutes of flight time with a 2S 850mAh battery, mixing acro flying and cruising. Utilizing a smaller 2S 450mAh battery diminished flight time to about 4 minutes, and I additionally observed extra voltage sag. I like to recommend sticking with bigger packs like 850mAh for extra balanced efficiency, particularly in windy circumstances, the place the additional weight truly helps stability. For instance, I flew this quad in 20MPH winds as proven within the video, and whereas not excellent, it remained manageable. In calm climate, the drone performs even higher.
As for sign and vary, they’re spectacular. Due to the variety ExpressLRS receiver and the 400mW VTX, you would theoretically fly 1km to 2km with out situation. Nevertheless, I don’t advocate inexperienced persons try flying that far—discovering this tiny quad in bushes after a crash could possibly be a problem!
What Can Be Improved
There are a couple of areas that could possibly be improved with the Acrobee75.
One of many foremost points I encountered was with the OSD (On-Display Show). The OSD textual content would randomly disappear for a couple of seconds earlier than reappearing. Whereas not a deal-breaker, this may be distracting throughout flights.
The Betaflight configuration additionally wants some refinement. For instance, the present sensor wasn’t correctly calibrated and it was under-reporting, and the RSSI warning was set too excessive, triggering alerts prematurely. Adjusting these settings would enhance the general expertise.
I discovered the FPV digital camera barely too darkish, even with the brightness on my goggles set to most. It is also the shortage of dynamic vary, which made the shadows seem too darkish, particularly when flying on a sunny day.
Regardless that the AcroBee75 has prop guards, I misplaced a couple of propellers on my first day of testing as a result of crashes. The props are press-fitted onto skinny motor shafts, which makes changing them simple, however they’ll additionally come off simply as simply. I like to recommend conserving further props readily available.
The U.FL connector for the VTX antenna is well-secured however may gain advantage from a dab of glue for added safety, particularly for these liable to crashes. I counsel utilizing a pliable glue like E6000 quite than scorching glue, which tends to soften because of the warmth from the VTX.
Moreover, the drone doesn’t stand flat when utilizing a big battery mounted on the underside, making takeoffs a bit tough at instances.
Tips on how to Setup
Establishing the AcroBee75 on your first flight is pretty simple. Right here’s the included person handbook.
The drone’s flight controller comes preloaded with Betaflight 4.5.0 firmware, and the board goal is ARCOBEE_75. The ESC firmware is Bluejay 0.19 48KHz with the goal Z-H-40.
Binding the Receiver:
- The built-in receiver makes use of ELRS 3.4.3 firmware with the goal NewBeeDrone Range 2.4GHz RX.
- Plug within the flight controller USB cable to energy the receiver. After a minute, the receiver will enter WiFi mode.
- Join your telephone to the ExpressLRS RX WiFi hotspot and open a browser. Go to the IP tackle 10.0.0.1 to entry the ExpressLRS internet interface, and enter your bind phrase there.
- It’s also possible to comply with different binding strategies offered within the directions: https://oscarliang.com/bind-expresslrs-receivers/
Betaflight Configuration:
- Configuration: Allow DShot beacon and set the arming angle to 180°.
- PID Tuning: Modify the charges to your private preferences.
- Modes: Assign switches for arming, angle mode, beeper, and turtle mode.
- OSD: Arrange the OSD to show RSSI_dBm and hyperlink high quality. Take away the RSSI worth, and alter the RSSI warning threshold to a decrease worth, corresponding to -90.
Conclusion: Is the AcroBee75 Value It?
The NewBeeDrone AcroBee75 BLV5 is a superb selection for pilots searching for a sturdy 2S analog Tiny Whoop. Whereas it’s not the most suitable choice for tight indoor areas, it’s extra fitted to outside environments and bigger indoor areas, and the additional safety from the propeller guards is effective. Its flight efficiency is clean and environment friendly, sturdiness is spectacular, and the general construct high quality is respectable. My solely minor concern is the occasional flickering OSD, not a deal breaker by any means, only a bit distracting.
