Each time I construct a brand new FPV drone, it’s like an journey that begins with buying the elements and ends with a maiden flight. On this assessment, I’ll deal with how one can construct a professional-looking 9-inch long-range drone on a funds utilizing the iFlight Chimera9 ECO body equipment.
Often, each DIY drone venture ought to begin along with your wants and expectations from the venture. In fact, these two components ought to be correlated with the accessible funds. Constructing an FPV drone your self will not be essentially cheaper than a ready-to-fly one. Moreover, it may be much more costly if you don’t make the prospection accurately.
After setting the necessities and funds, you may search for the FPV body that matches your wants. The remainder of the elements (Flight controller, ESC, motors, radio, FPV system, and battery) should be chosen to combine with the body like a puzzle.
iFlight Chimera9 ECO assessment
Disclosure: I obtained this 9″ body equipment, FC, and ESC as a part of a product assessment collaboration with iFlight. Though the elements had been provided without cost, all opinions on this article stay my very own, and the sponsor by no means influenced me. The remainder of the equipment proven on this assessment had been bought and paid on my own.
First, let’s talk about the funds for constructing this long-range FPV drone. The desk under exhibits the required elements and the value you will need to pay. In fact, moreover, you’ll need suitable FPV goggles and a transmitter. Subsequent, we’ll deal with every half, following the order through which you full the puzzle.

iFlight Chimera9 ECO body
The “ECO” world within the product may imply ecological/environmental or one thing economical/cost-effective. iFlight doesn’t give any clue on this side.
Adopting “dead-cat” (DC) geometry is a wonderful body for individuals who primarily document with the FPV digicam as a result of there aren’t any propellers within the view. The body is designed to exchange a damaged arm/motor proper on the sphere by dropping a number of screws. It will possibly accommodate 30x30mm measurement flight stacks and 30.5*30.5/25*25/20*20mm VTXs.
Out of the field, it comes with a entrance GPS mount that makes it not possible to mount a GoPro digicam. This challenge could be solved by moreover buying or 3D printing a rear GPS mount and a entrance GoPro mount. The Chimera 9 could be geared up with two RX antennas (vertically and horizontally put in).
The body equipment is available in a comparatively small cardboard field. It consists of the next: carbon fiber elements, TPU mounts + protectors, a set of MR30 motor connectors, XT60 battery cable, two battery straps, protecting facet panels, and plenty of screws+standoffs The screws are packed in separate luggage by kind, and a tiny label exhibits the scale. No person handbook is included, simply an exploded view drawing that exemplifies the way it ought to be assembled.
The body includes 4 arms, three plates (two backside and one high), and two digicam facet panels. iFlight features a pair of plastic facet panels that make the end result look clear {and professional} and defend the costly electronics from mud, filth, grass, and different particles. It has openings to entry the FC’s USB port and the O3 Air Unit’s micro SD slot and Sort-C port. A extra “deluxe” model of the Chimera Professional V2 facet panels additionally consists of LED lights.
Assembling the body could be completed in lower than one hour. First, set up the 4 6mm arms in a sandwich of two backside plates and safe it with the 4 FC screws (M3x30). Subsequent, add the eight standoffs and begin putting in the electronics. Lastly, set up the two mm high plate and apply the battery anti-slip rubber padding.
When absolutely assembled, the naked body weighs round 370 grams, and with all electronics (besides the battery), it weighs 800 grams. With a GoPro 12 on high and a large Fullsend 6S 8000mAh Li-Ion battery, you may anticipate a take-off weight near 2 kg.

The place can you purchase the Chimera9 ECO long-range drone body?
You should buy this body from Flight’s worldwide official retailer with 15% off throughout the Christmas sale for $82.44 ($96.99). This body and different iFlight merchandise are additionally accessible on Aliexpress and different platforms.
IFlight Chimera9 ECO: Flight stack
I opted for this construct for the BLITZ F7 V1.1 flight controller and the BLITZ E55 4-IN-1 ESC. This tandem can be used within the unique Chimera9 ECO. Initially, I thought of the 55A ESC too weak for the highly effective 2812 motors, however as it could actually deal with peaks of 65A, I thought of it fantastic, particularly since I don’t need to set up heavy payloads on the drone. It’s endorsed to make use of this ESC as a result of it has solder pads within the corners that match completely contained in the body and facet panels.
I really like constructing FPV drones utilizing flight controllers just like the BLITZ F7 V1.1. My eyesight will not be like after I was younger, and I favor to make use of connectors as a substitute of soldering tiny tabs. As you may see within the picture under, I related all peripherals (ESC, VTX, RX, GPS, and Buzzer) to the FC with none soldering. An arrow signal on high of the FC exhibits the orientation you want to set up contained in the iFlight Chimera9 ECO body.
iFlight Chimera9 ECO: Propulsion system (motors and propellers)
iFlight’s unique Chimera9 ECO is supplied XING-E 2809 800KV motors and HQ 9X4X3 propellers. My construct got here out extra highly effective as a result of greater FS2812 1150KV motors. The body can accommodate motors with 16x16mm and 19x19mm mounting patterns. The included motor screws have the right size as takes into consideration the arm’s and TPU motor protector’s thickness.
You’ll be able to solder the motors on to the ESC or use the MR30 for simpler alternative. Keep in mind to route the motor wires by the protect tubes in each instances.
Discovering 9″ propellers will not be simple, and are additionally a lot pricier than generally used 5″ ones. If yow will discover a set of 5″ for $2, you want to pay $8 no less than for a single 9″ prop. For this venture, I used factory-balanced 3MR 9×4.5 blades from Grasp Airscrew, a good US model.
Consultants contemplate that 900KV is a significantly better possibility for such builds than 1150KV, particularly in the event you use 6S LIPOs and want for cinematic flight efficiency.
Earlier than putting in the propellers on the motors, keep in mind to check the motor format (order) and rotation course; if something must be modified, you are able to do this from the BetaFlight Configurator underneath the “Motor” tab.
iFlight Chimera9 ECO: FPV system (VTX and Digital camera)
The factory-made Chimera9 comes with an onboard analog FPV system that, for my part, is much behind the spectacular expertise of digital platforms. I used a leftover unused DJI O3 Air Unit that gives onboard 4K recording, excellent FPV high quality, and as much as 10KM vary. The cable between the digicam and the VTX is about 10cm, which proved to be quick for the size of the body, and I needed to order a 15cm one. To cut back the jello impact, the digicam mount makes use of two silicon insertions.
As talked about, the protecting facet panel has two tiny home windows for the O3’s Sort-C port and micro SD slot. You need to use 1cm standoffs underneath VTX to set the suitable peak.
Greatest radio system for iFlight Chimera 9 ECO long-range FPV drone
TBS Crossfire was thought of the very best radio transmission system for long-range FPV drones for a few years. Within the final two years, ExpressLRS grew to become a way more accessible funds different to CRSF. For the reason that launch of the “Gemini” function, ELRS gained much more reputation. The BetaFPV SuperD RX and SuperG Nano TX permit simultaneous transmission over two antennas to acquire extra dependable communication than in all probability ever earlier than.
I put in the ELRS RX module on high of the O3 VTX, however there may be loads of room contained in the body of different spots. I mounted one antenna vertically and the second horizontally; this could give a greater vary.
Different elements wanted to finish the iFlight Chimera9 ECO body
Along with the first elements listed above, I used a GPS module and a self-powered buzzer for security. These two tiny elements are important whenever you fly over lengthy distances. The GPS module offers you the plane’s actual place and permits a fail-safe return to dwelling (RTH) when radio communication with the pilot is misplaced. Keep in mind that this function requires BetaFlight 4.3 or newer firmware.
When you crash it someplace within the wild, a self-powered buzzer can be essential to recuperate your LR FPV drone. It offers you audio and visible alerts that point out the drone’s place, even when the principle battery was disconnected throughout the collision with the bottom.
Within the desk under, I in contrast the elements used within the unique Chimera9 ECO and the one I constructed.

Really helpful battery for iFlight Chimera 9 ECO
On high of the Chimera 9 ECO, there may be loads of room for high-capacity batteries. You need to use LIPO and LI-ION packs as effectively. It will possibly accommodate batteries as much as 14cm lengthy utilizing two straps to safe it to the body.
I recommend utilizing packs with no less than a 30C discharge charge. iFlight recommends utilizing their Fullsend 6S 8000mAh Li-Ion pack, however different fashions may also match. For the preliminary exams, I used a CNHL 4S 1800 LIPO battery, and later, I moved to a 6s 4000mAh pack that offered a median flight time of twenty-two minutes.
iFlight Chimera9 ECO: Options
If you wish to construct a 9-inch long-range FPV drone, your choices are restricted, particularly in the event you favor the lifeless cat geometry with a clear FPV view. Priced for less than $30, the MARK4 V2 9″ (387mm wheelbase) is the most affordable 3K carbon fiber body. If you’re on a good funds, the DarwinFPV X9 body prices solely $59.99. With 8mm thick arms, the AMAX F9L+DC is a very sturdy body.
The benefit of the Chimera 9 ECO over the opposite 9″ FPV frames is the cleaner look, because of the 2 facet panels.
Last phrases
My journey ends right here, and I hope to start out a brand new construct subsequent 12 months, possibly even a bigger 10-inch one 🙂
Constructing the iFlight Chimera 9 ECO was enjoyable. I didn’t encounter any points besides the quick O3 cable. The field included not simply the carbon fiber elements but in addition the TPU elements and the 2 facet panels. For underneath 100 bucks, it’s in all probability probably the most full equipment.
The iFlight Chimera 9 ECO is a strong and heavy flying machine, and in case you are beginning with this passion, please severely contemplate constructing a smaller 3-5″ FPV drone. In my first real-life flight by FPV goggles, I received disorientated and scared, misplaced management of the drone, and crashed it over my spouse’s automobile. Fortunately, it was a 75mm TinyWhhoop and nothing horrible occurred.
Relying in your chosen motors, you may anticipate a payload capability of 1.8-2.3kg. It will possibly carry a Blackmagic 6k cinema digicam for skilled work.
Merry Christmas and Blissful New Yr 2024!
