TBS Oblivion LOS 6s

Although I have built quite a few quads now I though I would start to publish some of them starting with my latest build of the TBS Oblivion. This is a LOS build for the purposes of passing the national flying club tests. Although I could of used any frame I decided to go with the Oblivion purely because of the motor protection and LED placement. I was going to go with a Iflight VX5 Vertigo frame for the build but that didn’t have the motor protection....but I did a build with that frame anyways.

Unlike the pilots I've seen who can fly LOS without aids this build was going to require aid in the form of LED's. I had a good stock of LED's and started a dry fit around the frame. I originally thought that I would place a LED at each side of frame but then I thought about how I would address the colour.........after some thought I came up with using a mix of the betaflight LED and a LED controller however that would only give me three possible colour combinations which in the end would be ok as I would leave the rear of the quad alone.

The FC stack of choice would be the Ditatone F772S F50PRO which would provide me 6S power with the added bonus of a build in independent LED controller. I went with the Xing-E motors as I didn't really need premium motors but these motors had felt premium in the VX5 build so would go well with this build. I was aware that the holes for the motor would not fit so I used a file to create a wide enough hole for the motors to fit. I had change out the motor screws out for reduced height screws as the thickness of the Oblivion frame is lower than a typical carbon frame.

The next challenge was mounting the FC stack. Diatone give you the stack in a very well presented way but the the length of the screws would not give me enough length for the air gaps so I got some 55mm M3 bolts and cut them down to size to about 35mm to fit at least 30x30 mounting plate but also give room to at a VTX later.

I decided to replace the 35v Cap for a 50v cap which will help with filtering in the future and take the load from the 6s

So with the LED's I used a mix of Aurorarc 8 bit boards for the front and Matek 8 bit boards for the sides and I figured out that I would use the power from the Diatones in built LED controller to power the LEDS but then use the LED pad to control the LEDs for the front and one of the sides from beta flight. I connected the 2 Aurorarc boards together as clean as possible and drilled a 2mm hole to attempt to cleanly route the wires up to the board. I then used the signal out wire to connect to the one of the side Matek boards. For the other Matek board I used the inbuilt controller board and would be able to change the colour manually by pressing the button.

The canopy needed some customisation to fit the stack so I just used a Dremel with a sander attachment to give me the room it needed.

I would love to see the canopy hack. Any chance to send me the pics?

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..
