Tubular 8inch LongRange 3D printed Quad

As an experienced long-range pilot who reached 100km in 2013, I decided to build a new 8" setup that would meet my mountain-surfing needs in the 5-10km range. I reached out to an old friend, Nic (eyefly), who is a genius at designing frames. He had previously been working on carbon fiber rod frames with 3D printed joints, and I was initially skeptical about their durability and stiffness for a larger 8" frame. However, I was pleasantly surprised when Nic provided me with his latest design, an 8" tubular quad using 10 and 8mm CFK tubes and 3D printed connectors in CF PETG and TPU mounting prints.

I received the tubes and cut them to length, then used two-component "UHU PLUS ENDFEST 300" to glue the base frame together. The end result was an extremely stiff and lightweight frame that exceeded my expectations. I continued to mount motors and components on the TPU mounting parts, which were fixed to the rods using zipties.

After flashing BF 4.4 with default settings, I took it for a test flight in calm wind conditions. The quad flew exceptionally well, but I could tell that after some fine-tuning, it would be an absolute beast.

Thank you Nic for helping me out on this one :)

just purchased the 3008 1155kv T-motors , you seem to be the only one with them. how do you like the feel of how they fly?

very powerful, and extremely efficient

flight time ?

maximilian_pircher   May 03, 2023 

above 20 minutes in high wind conditions. its not a long flight quad. its a long range quad that can cope with high winds and speed.

Ive started my 8" build. glad to see someone bringing back tube frames!
3D parts are complete, CF tubes arrive in a couple days.
looking forward to the build!

Even more impressive. i was really wondering why every photo was showing the build on a beach. i also have to solder outside,small apartment life with family of 4.
i was thinking of sharing your build on DroneNation. not sure if you've heard of it? its an only community of like minded pilots. well its an app for FPV pilots lol. i think a bunch of people would find your build interesting

sure feel free

Now I understand :D I've seen the pictures and I was like wtf, who brings a desk to the beach to build a drone, it's so funny :D :D

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..
