5" iFlight Lowrider 6S - High Cam Angle - 3D

Ever since I started flying 70° camera tilt and 3D, I noticed my first quad (4s) just wasn't cutting it. The battery would sag out within seconds, severely hampering my style. The quad also seemed a bit heavy for 70° tilt; while flying level, I was having a very hard time seeing the ground (in Liftoff I don't have this issue).

My solution was to build a much lighter quad that uses 6s. The lighter weight will increase the thrust/weight ratio and allow the quad to pitch forward more while maintaining a lower airspeed. The 6s battery and 1700 kv motors should minimize voltage sag.

To lower weight, I did a few things:

  1. I used the new Holybro 20mm Mini Stack which saved a lot of weight compared to the Matek FC/PDB combo that I had used in my previous build. This stack is SWEET. Not having the ESC's on the arms is much lighter and brings the COM inward.
  2. The Lowrider frame is a bit lighter than the iFlight IX5 I had been using and pulls the COM even further inward. The narrower arms should also be more efficient since they will obstruct less air.
  3. For the antenna, I used just the Axii MMCX, as opposed to the pagodas I had been using. I also ommitted any SMA connectors since they weigh a lot.
  4. The Caddx Tarsier is ligher than the Runcam Split I had been using, and also allows me to ommit the seperate FPV camera, saving even more weight.
  5. Used all Titanium hardware.

Total Weight: 538 g (compared to 592g for my starter quad)

This frame is designed for a 30.5x30.5mm stack, but it has 20x20mm holes that are designed to be used with the inner set of screws that secure the arms. Drilling the 30.5x30.5mm holes out of only the bottom plate with an 11/64 drill bit allowed me to move the press nuts to that set of holes, and for me to install the mini stack into the 20x20mm holes.

Until now I have been using Runcam Splits on most of my builds, so I am extremely excited about the new Caddx Tarsier. High camera angle means that use of a GoPro would be impractical, since it would have to be practically laying on it's back, and would likely be in view of the FPV camera. The camera pod I made on my starter quad worked well for me, so I threw one together for the Tarsier.

I've only been able to hover test, but so far it seems super smooth and responsive. I will update once I have made the maiden flight.

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
