Key Features

  • Radix LI F4 FC with Bosch Sensortec BMI160 gyro and Graphical OSD (Vector Artificial Horizon, Gyro spectrum analyzer)
  • Aikon AK32Pin 35A Blheli_32 ESC with DSHOT 1200
  • 3S-6S capable stack
  • Dry weight: 110g

Build Notes

  • The Aikon AK32Pin ESC does not quite fit - the rear posts obstruct slightly. Had to sand down the tab of the battery terminal very slightly (See picture)
  • The iFlight iX3 Lite v3.1 (Note v3.1 with the black posts, not the v3 with the red posts) has M2 stack mounting holes, had to drill to M3
  • The VTx is mounted on a WhiteNoiseFPV Nano mounting board, with the XM+ receiver sitting on top
  • The motors are the 3850KV variant of the AB1404
  • The standoffs are 5mm high, not 6mm. I found these quite hard to come by
  • Separate 5V BEC was used to power the Rx / VTx, as Radix do not recommend powering a 5V VTx from the LI FC. It is in the rear, next to the XT30
  • You can just about do the same build on an iX2 Lite v3 (2.5") frame, but that has 2mm less stack height (evilBee v1 was 2.5")

I am by no means an expert in quad building, any advice on how to improve part selection welcomed

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
