Mobula7 HD Aluminum Build

This is my mod of the Mobula7 HD. I replaced the frame with one made of aluminum because i destroyed the plastic frame :-) and made an upgrade of the VTX antenna and installed a Foxeer Lollipop FPV instead of the original one. On the ESCs i replaced the firmware with the jflight JESC firmware running on 48kHz.

Update:
I found an original aluminum frame from Happymodel called snapper8 but it's a 85mm version. (added link below)

Today i could fly some rounds in my garden and i have to say that i am a little disappointed from the aluminum frame. It bends very easy :-(
I was able to fix it and bend it back but compared to the original plastic frame it's very weak. Maybe the copter is too heavy for the frame...
But the flight performance is very smooth, i like it.

Does the Mobula 7 have a ufl socket for its vtx out of the box? I'm not upgrading the fpv camera, just the antenna.

Will a Lumenier Axiis Micro ufl antenna go in a Mobula 7's standard vtx? I'm planning to fit one inside when my quad gets here, and hopefully i won't have to solder anything for an antenna upgrade.

Hi, yes, the vtx has a ufl connector out of the box. I think you can use the lumenier antenna because it looks similar to the Foxeer i used in my build

Hey, nice look , i thought about the same frame in the past but then i found somethin better: i swapped my mob7HD to an 85mm frame (the one frome the eachine cinecan) and got about the same weight like your build but with the bigger 2" props (dalprop 2035), much better performance ! trust me, give it at try when your frame has bend to its end ;)

The pic below shows my 85 version with caddx beetle (only cam) and TBS unify pro nano vtx. just swapped it cause this thing flys awesome withjout the extra weight from the turtlev2, hd recording is now on one of my toothpicks..

Hi, thanks for your comment, that's an interesting version, i will give it a try as soon as my frame is broken :-).

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..
