Why take into account a 7-inch FPV drone in a world more and more shifting in the direction of smaller, sub-250g fashions? Properly, bigger drones outperform smaller ones, carry heavier payloads, and provide longer flight occasions. They’re additionally sooner, important for conditions requiring velocity and endurance. The GEPRC MOZ7 V2, that includes 7.5-inch props and highly effective 2809 motors, addresses this want completely, delivering velocity, stability, and flight time for high-speed chases and long-range cinematic flights. On this evaluate, we’ll discover its options, specs, and flight efficiency to see if that is the precise drone for you.
Priced from $664.99, the MOZ7 V2 shouldn’t be an affordable drone. When you’ve got a decent price range, you may construct your personal 7-inch FPV drone for as low-cost as $150, though it definitely gained’t match the options and efficiency of the MOZ7.

Design and Construct High quality
Technically, the MOZ7 V2 is a 7.5-inch drone, tuned particularly for 7.5-inch props. Whereas it will probably use customary 7-inch props, utilizing the really useful 7.5-inch props provides higher efficiency and longer flight time.
GEPRC claims the body has been strengthened over its predecessor, leading to higher crash resistance and extra steady flight efficiency. Nevertheless, this reinforcement additionally means elevated weight. Though GEPRC’s specs listing the drone at round 750g, I measured practically 843g and not using a battery—virtually 100g heavier than marketed. A lighter design would considerably enhance effectivity.
Measured weights:
- With out battery: 843g
- With 6S 2200mAh LiPo: 1218g
- With 6S 4000mAh (21700 6S1P): 1265g
- With 6S 6000mAh (18650 6S2P): 1480g
The heavier weight partly outcomes from its spacious body design, which simplifies upkeep, restore, and modifications—a refreshing change from tightly packed competitions just like the iFlight Chimera 7 Professional.
The aluminum cage for mounting the digicam provides ample lens safety, with no propellers seen within the digicam’s view.
The aspect panels, designed with correct cutouts, shield electronics from grime and facilitate quick access to USB ports and the DJI O4 Air Unit’s SD card slot. These aspect panels are detachable for weight financial savings. Fortunately, GEPRC skipped pointless RGB LEDs, avoiding additional price and useless weight. There are a number of cooling vents retaining the O4 Professional Air Unit cool.
GEPRC has clearly prioritized practicality within the MOZ7’s design. The hard-mounted XT60 connector simplifies battery connections.
Nevertheless, GEPRC’s claims in regards to the aspect bars “guaranteeing a balanced heart of gravity” appear doubtful. Whereas these bars improve the underside plate structural power, their precise practical profit is unclear. They don’t add vital weight, so I’ll simply go away them.
Regardless of GEPRC’s enhancements, the MOZ7 V2 nonetheless feels barely tail-heavy, particularly when fitted with lengthy antennas. Utilizing a GoPro within the entrance will help steadiness the drone. Moreover, it’s attainable to swap the places of the GoPro mount and lens cap to additional shift the middle of gravity ahead.
With out an motion digicam, count on tail heaviness, and you need to shift the battery ahead to compensate. Why is that an issue? Properly, when one aspect is heavier, the motors on that aspect must work tougher continually.
I respect the sturdy arm guards, which double as touchdown gear, defending the underside plate throughout landings.
Digital Parts
The MOZ7 V2 comes with GPS—in reality, you may’t get it with out GPS. The included buzzer and neatly routed GPS wires showcase GEPRC’s consideration to element. GPS module tilt angle could be adjusted primarily based in your deliberate cruise velocity.
It’s good to see that Failsafe and Rescue modes are arrange out of the field, which is uncommon to see in BNF FPV drones. Whereas the default settings look okay for essentially the most half, I strongly advocate reviewing the Rescue mode values to make sure they fit your flying atmosphere. Take a look at my tutorial on Rescue mode: https://oscarliang.com/setup-gps-rescue-mode-betaflight/. Settings comparable to Return Altitude, Return Floor Pace, and Throttle Hover and many others, must be personalized to your setup and necessities. Moreover, Channel Fallback isn’t set by default, and I strongly advocate configuring it as nicely—check with my Rescue Mode tutorial for steering.
The GPS unit features a compass, but it surely’s not linked to the flight controller, presumably to simplify the construct. For Betaflight customers, this isn’t a problem for the reason that compass isn’t used for “return to dwelling”, however it will profit iNav customers. In response to GEPRC, the TAKER H743 BT flight controller is suitable with iNav, although I haven’t personally examined this.
Though the specs declare the included O4 antennas are RHCP, they’re really LHCP, identical to the inventory DJI O4 antennas. All of the antennas have SMA connectors.
The flight controller options twin gyros, which appears considerably overkill since just one gyro can be utilized at a time. Nevertheless, having two gyro choices does let you select the one which performs higher, making tuning probably simpler—albeit at the next price. For my part, that is barely pointless.
The 2809 motors are fairly beefy for a 7/7.5-inch FPV drone, as typical setups normally use 2806 or 2807 motors. Bigger stator dimension interprets into extra highly effective and torque, making the drone responsive and steady, enhancing flight expertise.
My major criticism is the ESC. Firstly, the 50A present ranking feels barely low for a 7.5-inch FPV drone, particularly when even GEPRC’s 5-inch Vapor mannequin ships with 60A ESCs. Whereas the MOZ7 V2 is meant for environment friendly, long-range cruising fairly than aggressive freestyle or racing, and 50A is adequate for Li-ion battery setups (because it’s close to inconceivable to drag that a lot present from Li-ion packs), I really feel like a premium drone ought to a minimum of match the price range choice. One other concern is GEPRC’s use of a prototype model of the BLHeli32 firmware on the ESCs. That is problematic as a result of firstly, it’s an unofficial testing model, and secondly, BLHeli32 itself is now thought of a useless firmware with no deliberate future updates.
DJI O4 Professional vs GoPro
A standout function of the MOZ7 is the seamless integration of the DJI O4 Air Unit, which data spectacular 4K video at 60 or 120fps immediately onboard. The picture high quality rivals high-end motion cameras just like the GoPro. For a lot of hobbyist pilots, the O4 Professional eliminates the necessity for an motion digicam, saving each weight and value. The O4 Professional digicam is mounted utilizing vibration-isolating silicone inserts, important for reaching jello-free flight footage.
The included MOMODA2 antennas are LHCP.
The O4 Professional Air Unit is mounted on customized heatsink, which successfully addresses the infamous overheating points, permitting dependable operation even throughout extended floor idling whereas buying GPS lock.
For pilots preferring utilizing motion cameras such because the GoPro or DJI Motion 5 Professional, GEPRC conveniently gives mounting choices out of the field.
Twin-band Gemini ExpressLRS Receiver
GEPRC provides three receiver choices: PNP, ELRS, and Crossfire. I’m reviewing the ELRS model right here.
The MOZ7 V2 is provided with the GemX Twin-Band ExpressLRS Receiver. For these unfamiliar, Crossband Gemini represents cutting-edge ExpressLRS expertise, concurrently using 868/915MHz and a couple of.4GHz frequencies to transmit alerts, considerably enhancing hyperlink consistency, particularly in environments with potential frequency interference.
Along with Crossband Gemini, the receiver additionally options true range, which means it makes use of two antennas, every able to working on each 868/915MHz and a couple of.4GHz frequencies. One antenna is horizontally mounted on the entrance of the quad, and the opposite is vertically mounted on the rear. This association ensures a minimum of one antenna maintains line-of-sight with the transmitter whatever the quad’s orientation, lowering sign blockage by parts or the battery.
Nevertheless, to totally leverage the GemX Twin-Band receiver’s capabilities, a dual-band transmitter such because the Radiomaster GX12 radio or Nomad transmitter module is really useful. For those who solely have a standard single-band 2.4GHz ELRS transmitter, you may nonetheless bind it to the GemX receiver and function in regular mode, however you gained’t get the dual-band advantages.
Battery Choices
You’ve the pliability to mount the battery both on the highest or backside plate, and GEPRC gives two battery pads for this goal. I personally desire mounting the battery on the highest plate, as that’s the place the battery connector is situated. The utmost battery size for the highest plate is roughly 16.5cm.
Nevertheless, when you’re utilizing an motion digicam (comparable to a GoPro) or an extended battery that exceeds 16.5cm, the highest plate won’t present sufficient area. In that situation, mounting the battery below the underside plate is a viable workaround. Nevertheless, watch out throughout touchdown to keep away from damaging the battery cells when doing it this manner. Additionally, you will want an extended cable to attach the battery.
GEPRC thoughtfully consists of two battery straps of various lengths—250mm and 300mm—guaranteeing compatibility with numerous battery sizes.
Flight Efficiency
The M10 GPS efficiency was spectacular. In my assessments, I achieved a GPS lock (8 satellites) in nearly 1 minute and 10 seconds (chilly begin). After 5 minutes, the satellite tv for pc depend rose to round 19 satellites, offering sturdy positional accuracy. Between altering batteries, I may get a lock once more inside 10-20 seconds.
I carried out flight assessments utilizing a 6S 6000mAh Li-ion battery (see evaluate) in wind situations of 15-20 mph:
- Hover throttle: round 30% (or 26% with a lighter 6S 4000mAh Li-ion pack).
- Prime velocity: about 110 km/h (greater speeds achievable with LiPo batteries).
- Optimum cruising velocity (environment friendly long-range flight): round 60-70 km/h, comparable to round 35% throttle.
By way of maneuverability, the MOZ7 V2 carried out nicely—very steady even in sturdy gusts. Freestyle maneuvers felt clean. After all, it’s much less responsive and fewer punchy than a 5-inch freestyle drone, however the MOZ7 V2 provides superior stability and endurance for long-range flights, and able to carrying heavier payload.
Throughout my take a look at flights, I achieved slightly below 16 minutes of flight time, overlaying a distance of over 15 km.
For Li-ion battery setups, it will make sense to set a throttle scale restrict round 80%. That’s as a result of at greater throttle ranges, Li-ion voltage sags a lot, it provides little or no additional energy. Cutting down throttle helps you obtain higher throttle decision, bettering flight management.

Sturdiness
All through testing, I had a number of crashes, together with a full velocity crash into the bottom from about 10 meters excessive. Surprisingly, the drone itself suffered no structural harm, aside from some bent propellers. The body held up rather well. Nevertheless, the weakest level gave the impression to be the receiver antenna on the rear. As a result of it’s constituted of inflexible plastic, it simply snapped off on the base within the crash. I’d advocate GEPRC to modify to a versatile materials for the receiver antenna sooner or later to enhance sturdiness.
Areas for Enchancment
- Embrace ND filters: It will be helpful if ND filters had been offered for the O4 Professional digicam, which is crucial for cinematic footage. Find out about some great benefits of ND filters right here: https://oscarliang.com/nd-filter-fpv/
- ESC firmware: The 4in1 ESC makes use of a prototype model of BLHeli32 firmware. Whereas it would carry out simply positive in follow, it will be preferable and extra future-proof to make the most of an formally launched model, and even higher a firmware that’s actively maintained comparable to AM32 and even Bluejay.
- USB powering GPS/Receiver: The flight controller’s USB port doesn’t energy the GPS or receiver. You might want to plug within the battery to energy these parts.
- Versatile RX antenna: As talked about, the rear RX antenna is simply too fragile and must be changed by a extra versatile antenna for improved sturdiness.
- Self-powered buzzer: Given its premium value level, and long-range design, it will be helpful to incorporate a self-powered buzzer for enhanced security and simpler restoration in crashes. See suggestions right here: https://oscarliang.com/best-5-inch-fpv-drone-parts/#Beeper
The right way to Setup
Out of the Field Setup
Earlier than the primary flight, I did the next:
- Eliminated all labels on the drone.
- Eliminated the motor path playing cards—these point out the motor spin path (which is utilizing Betaflight default – props in).
- Eliminated the protecting movie from the digicam lens.
- Positioned the battery pad on the highest plate.
- Put in the 2 battery straps by becoming them by the holes below the highest plate.
- Put in the 2 O4 antennas, and one receiver antenna on the again.
- Plug in a battery utilizing a smoke stopper for testing, be certain it powers up positive.
Firmware
- The flight controller (FC) board goal is GEPRC_TAKER_H743, and it comes preloaded with Betaflight firmware model 4.5.1. For inventory CLI Diff, see right here.
- ESC Firmware: BLHeli_32 31.9.2 ST G0 05
- ELRS Receiver Firmware Goal: GEPRC 900/2400 Gemini Xrossband RX, firmware ELRS 3.5.3 (ISM2G4)
Betaflight Setup
Last Thought
The GEPRC MOZ7 V2 stands out as among the finest 7-inch FPV drones at present accessible, particularly relating to its complete options and wonderful flight traits. Regardless that it’s spectacular, thorough testing revealed some areas for potential enchancment—most notably the delicate receiver antenna and the ESC firmware model. These minor points aren’t essentially deal-breakers however are price noting for future updates from GEPRC.
Total, I used to be notably impressed with its PID and filter tune, providing a extremely satisfying flying expertise. The body held up very nicely in crashes and the design is consumer pleasant. With a large enough battery, flight occasions of 15 to twenty minutes below ultimate situations are achievable.
