The mounting brackets that were designed last week have now been manufactured.

The bracket that holds the LiDAR to the top of the helicopter is pictured below, it was laser cut out of 0.7mm stainless steel.

The second bracket bolts on to the underneath of the helicopter and holds the battery, computer and power distribution board. Also made of 0.7mm stainless

Here is a photo of the computer stack without wiring. The brown board closest to the camera still has a few components that needs attaching. These components will allow the computer to control the heli.

 Both the LiDAR and the computer stack attached on the helicopter, still no wires (that is a job for next week).

Yesterday, some quick payload tests were carried out to see whether the helicopter could comfortably lift the planned sensor array (estimated to weigh around 700g).

Unfortunately the only thing we had in the office that we could easy to strap to the helicopter and weighed around a kilo was a carton of juice... Very scientific. 

The helicopter remained very controllable, stable and only needed about 60% throttle in the hover (so has some spare power left).
