Hyperlow CG 5", 6s, 2150KV

For this build, I wanted freestyle quad that had a lot of high-end power to that would allow me to float over objects with some low-end torque to allow me fly tight spaces. I elected to go with a moderate 2150 KV, 6s setup on a 5" Hyperlow CG frame. The Hyperlow CG frame was purchased from GETFPV and is relatively low profile with a lot of room for accessories. The frame comes with two decks that mount forward and aft of the ESC/FC stack. While the frame is a little challenging to put together compared to other quads, I would recommend it for a first build due to the large amount of space. The frame comes with two different height standoffs that allow for a slammed deck if running an all-in-one flight controller. I ran the standard size standoffs since I used a 4-in-1 ESC. The black standoffs were replaced with knurled blue standoffs to match theme of the build. I outlined the frame with an acrylic blue paint pen. I was nervous I would ruin the frame if I decided to paint; but paint pen was easy to use, and the frame looks sharp. All components were purchased from GETFPV.com, RACEDAYQUADS.com, BRAIN3D.co and AMAZON.com.

The motors are TMotor F40 PRO II, 2150KV (2306 stator), purchased from GETFPV. I am running the 2150 KV motors with 6s although they were designed for 5s. I limited the max travel on my throttle using my Taranis QX7, I do not require the max power when running 6s on these motors. I am using four CLRacing 35mm blue LEDs which are covered with RDQ’s 3/8-inch blue braided mesh wire wrap. The wire braiding has enough openings to allow the LEDs to luminous clearly. I used a BNTECHGO blue 18 gauge silicone rubber insulation wire in between the CLRacing LED’s and 4-in-1 ESC.
Originally, I planned to use a DALRC 45A 4-in-1 ESC with BrainFPV Radix flight controller (as seen in the picture with the build components). I rushed when soldering the DALRC ESC and smoked it when I plugged in the battery, doh! Thus, I used a TMotor F55A Pro II 55A BLHeli32 4-in-1 ESC with a 10V BEC. I decided to use a Lumenier Lux Ultimate F7 flight controller with Dual Gyros because it has an onboard voltage regulator and used the VBAT output of the ESC (Radix requires a 5V input). I mounted both the ESC and flight controller using blue M3 Flight Controller Vibration Dampeners from RDQ. The ESC was rotated 90 deg to simplify the path used to run the motor wires. The motor wires are located under the forward and aft decks (note the zip ties in the image were removed before the ESC was mounted). Rotating the ESC 90 degrees located the battery pads to the right side of the quad, which resulted in the XT60 connector and capacitor being located on the side of the quad. Rotating the ESC resulted in a lot of open space inside the frame. The 35V, 470 uF capacitor is located on the bottom side of the ESC’s battery pads.

Next, I laid each component out in the quad to make sure I had adequate cable length to wire each component to the Lumenier Lux F7 flight controller. The Lumenier Lux F7 is a nice flight controller that I will use again, I highly recommend this component. The 3D printed camera mounts that come with the Hyperlow CG frame allow an easy mount of the Foxeer Predator Mini V3 1000TVL 1.8mm FPV Camera.

The VIFLY Finder V2 FPV Drone Buzzer is mounted on the forward deck, behind the camera. The buzzer is rotated such that the disarm button is facing towards the forward hole in the top plate, thus the button on the buzzer is easily accessible after each flight.

The Team Blacksheep (TBS) Crossfire Nano Rx is mounted on the forward deck, next to the buzzer. The TBS Immortal T antenna is mounted at the front of the quad, on the bottom of the frame, underneath the FPV Camera using an blue 3D printed mount from Brain3D. A set of four blue motor bumpers were also purchased from Brain3D.

A TBS Unify Pro 5G8 HV SE with a MMCX connector is mounted behind the ESC on the aft deck. A 7cm SMA Female to 90deg MMCX Male cable runs to the Lumenier AXII Stubby 5.8 GHz RHCP VTX Antenna. The VTX antenna is mounted inside of a blue 3D printed AXII antenna support, purchased from Brain3D. The antenna support support also has locations to mount the 2 antennas coming from a FrSky reciever. I cut these off since I was using the Crossfire Nano Rx with an Immortal T antenna.

A Matek SAM-M8Q GPS Module was mounted on the back of the quad underneath the 3D printed VTX antenna mount. I do not have a direct line of site to the sky with my GPS antenna, but I still get sufficient satellite reception. I am only using my GPS module for a velocity indicator. I have the number of satellites to arm the quad set to zero and fail-safe return disabled in Betaflight. I recommend you mount your GPS antenna with a direct line of site to the sky if you intent to use GPS as a failsafe feature.

I am using a GoPro Hero 7 and Brain3D black 3D printed mount. The GroPro Hero 7 and warranty was purchased from BestBuy who will replace if damaged, no questions asked. You cannot beat BestBuy’s warranty; you should really consider purchasing your GoPro from BestBuy if you intend to mount it on a quad.

I'm running Tattu R-Line, 6s, 1050mah and 1300mah battery packs. I will run the 1050mah when I need a little extra speed/maneuverability and 1300mah when shooting HD video. Finally, I am using Gemfam WinDancer Blue 5042 3 Blade props that are mounted using blue M5 motor nuts.

Thanks to the folks in the Facebook group FPV Builders for sharing their knowledge throughout the build!

Right.... Im with this Zakre256 cat.... This is a great build and write up. I kinda feel bad I haven't done one to this length, and so I'm shooting piece by piece (ehh... or fairly close) on a mockup right now (oh yeah! that's what you do with those!). I like that you used the Pro II's... I have an old LX5 I refer to as "the tank"... it rides on the same, and I have to say that it still impresses me to this day.

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
