Frame Assembly

And here is the frames assembled with the custom TPU Gopro and DJI camera mounting. They are specifically designed for the DJI camera mounting and the DJI Air unit.
The FR7 is a purpose built for fast mid and long range cruising. Designed to pull clean HD footage without props in view.
The FR7 combines design features are:
• Modified arm geometry (deadcat-ish) keeps the large 7” props out of view in any video format - Project 399 SuperG+
• HD under FPV cam allows for a lower CG and allows for super low perspective HD footage - MB Epic
• Split bottom plate allows the HD cam to be as low as possible - Impulse RC Reverb (and SuperG+):
• Interlocking arms minimized arm movement/slop - Impulse RC Alien

Motors

I am using these motors:
4X Garila X2507 1500KV
Mounting the motors is pretty straightforward. I ensure I could used the longest screw to secure the motors without being too long.

ESC and FC

I used the iFlight SucceX-D F7 Stack (F7+60A ESC) on the Second FR7 7 Inch build. The SucceX-D F7 is designed to work seamlessly with DJI’s new HD FPV system. To make things even simpler, the DJI Air unit can just be plugged into the FC with the included wire harness. Before I start mounting I removed the flight controller from the 4-in-1 ESC to apply the conformal coating to all surfaces of the boards except where I am going to be soldering.

ESC Soldiering

Here I am soldering the motor wires to the iFlight SucceX-D F7 Stack (F7+60A ESC). What a beast of of a ESC!!

DJI Air Unit Installation

I am using custom TPU cages for the DJI air units. The rear holes were utilized from stand offs and the second set were drilled and M3 bolts used to secure the Air units to the frame. The hardware is stainless to reduce correction and the nuts were latter switched out with locking stainless nuts. Over all I am VERY happy how this custom DJI air units cage worked out. I am quite pleased how by installing the capacitor to the side provide the perfect amount of room for the DJI unit to be installed and all the harness reach their perspective sockets without being strained.

Antenna Installation

On the first and second FR7 7 Inch build, both the DJI units were secured in the same way as can be seen my the pictures. Also take note haw the attennas were mounted to rear custom TPU, 3D printed mounts.

Camera

Next we can add the camera. We utilize the custom TPU printed part which was designed to fit specifically for the DJI camera.

Finishing Up

Now it's time to wrap it up! Screw the aluminum standoffs to the bottom plate and mount the top plate. I also zip-tied the battery lead to the an aluminum standoff to reduce stress on your stack in the event of a battery ejection and zip-tied the motor wires to the arms to avoid snags.

Awesome build man! I'm considering using 4s for my long range build as well! What's the flight times you are getting with the 4s though?

First, this right hurr is some QUALITY kwerd porn. I have been looking at those Garila motors since 2206's were new, and I have always built 5" or micro, so I thought they were massivly overkill. I was afraid I would ruin my batteries, but you're probably in a safe place with those huge ass packs. How do you like them?

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
