I made a OpenHD remix of dave_c‘s awesome #Microlongrange project.

My goal was to create a quadcopter with 10km+ video range while still being able to fly below 250g starting weight for legal reasons.

Very interesting build; thanks for sharing!
What range & flight time do you get with it?

@Slowy, any updates?

Edit: URLs for OpenHD forum changed, new working link is: forum.openhdfpv . org/t/microlongrange-openhd-edition/379 (had to put spaces in URL, I guess I'm too new to post links)

What did you use like wifi dongle for your Ground Sation ?

Sweet build! Could we get a video to get an idea of the video quality though?

I can record some when the weather gets better and I can fly again. unless then see this video from last year with the same camera and lens mounted on a plane:

please watch on YT in highest quality, not the embedded video.

Good looking build! Is that tpu at the bottom you have protecting the vtx/pie, piezero??

Slowy   May 06, 2021 

Hi and thanks !

the lower part (black) is PLA+ and thats a "Pi3 mini" -but if you follow the link there is a version for Pi0 too.
the white part holding the "VTX" is printed in PETG because of heat. The blue parts are TPU.

Great work getting it all in there!

This is a really cute build! I guess the video transmitting would also be possible over a 4G/LTE dongle?!

Slowy   May 06, 2021 

yes there is basic support for video over LTE in there. No telemetry and RC thought.

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..
