This my take on a 3" long range quad, the only thing I would really change as of now is the esc but it just won't die and the fc becasue of the lack of extra uarts.

Interresting vtx antenne mount. Not afraid the mmcx will break of the vtx?

emofes Jun 22, 2018

not really, this quad isn't meant t br bashed around a lot. The antenna is mounted to the arm which should relieve some strain when I do crash.

great looking build!

Quadlite Jun 20, 2018

Greaat looking build. That frame is really cool. The other day I saw someone on here put 4 inch props on that frame and it actually fits! BTW I've been curious about those superman motors for awhile but haven't seen any data on them. How do you like them? Is there anything you could compare them to?

emofes Jun 20, 2018

Yeah, it was designed to go up to 4", I owuld love to get some efficient 4" tmount props. I like the motors, they are low kv so not the fastest but still fun to fly, they can handle 5s though which is cool. On 4s they're not as fast as some higher kv 1106 but I think they are more efficient. rotorx does have some higher kv 1404's though.

Quadlite Jun 20, 2018

Thank you. Thats really good to know. As far as props id look into the rotorx 3044tx triblade props. They arent necesarily that efficient, but they should pair nicely with your motors and maybe give you a little speed. I'm about to use them with the rcinpower 1108 6800kv motors. They are absurdly powerful (500grams+ each), but NOT efficient at all. im really hoping they are still useable on a low mah pack.

I would look at the avan mini 3" props, from what ive seen they are resonably powerful and efficient.

q-ratz Jun 20, 2018

Now that is a beauty. Can please share a link to a Video taken with that quad? I am interested to see to what extent the props are in the picture. I have seen a video with 4inch props, where the props where really dominant in the picture.

I will when I get a chance, haven't had a chance to fly since its been raining here. There is a "hooded" canopy they designed that you can print to mount the cam on top to get the props out of view.

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..
