DJI Cinepro

I have shoehorned in a DJI Air Unit into my Geprc Cinepro 4K.

While in pieces I have conformal coated the ESC and FC. I've had to stretch the top and bottom plate to fit in the Air Unit in by only using a single pair of screws on the front of the bottom plate and rear of the top plate. I've also been able to do away with the VTX from the stack.

I have tried to upgrade the FC to BF4.1, but because I'm not very good with tuning etc. I have re-flashed the shipped 3.5.7. With the added 3d prints to hold the Air Unit and cage protectors and a Caddx ND filter the dry weight is 165g. Adding a 4s 650mah takes it to 247g.

i am thinking of buiding one 2 inch for indoor use, with a full air unit. How tight is the Air unit inside the frame? is there space for a tbs nano receiver?

Woz86 Jul 22, 2020

yo man, sorry not been on the site for ages. I've had to print a bracket that raises the top plate and insert some 5mm brass standoffs. should be just about enough for the receiver.

what sort of flight times are you getting and is this the 2 inch frame or the 3 inch?

Woz86 Jan 08, 2020

2" frame i think. getting 4 minutes odd with a 650mah 4s

On paper this feels like a brave but misguided idea, and yet there it is! How is it flying?

The addition of the air unit, to my untalented fingers, hasn't adversely affected the flight characteristics. I think it's 14g heavier than the standard setup. I've only been cruising with it so far, but that's about all I plan on doing with it.

Yes, not really a racing rig, I have one with the Tarsier and it is indeed a great little cinematic cruiser.

Excellent work, this looks far from unskilled! 🙂

Well I'm about to wholesale plagiarise your XL8 DJI build. It looks really cool and I have a spare frame just sitting on my shelf. Just need to get another air unit and a Matek PDB that doesn't have a VTX built in.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
