I recently faced down assembling the Bluetooth data link. After a whole lot of fiddleass soldering and cussing I was somewhat relieved (and surprised) to discover they actually worked. Not only that, they worked out at the field too. I have not yet tested their distance limit (claimed to be 1 km) but 50-60 metres was sufficient to at least get some basic data back whilst airborne.
I was keen to know the in-flight BL Ctrl temperatures, particularly with the Canon 5D on board. Without the 5D the range of temperatures for the eight BL's was 61 - 81°C. With the Canon 5D the range was 68-95°C.
95°C !! Ye Gods. Is that normal?
And this is with the 16 heat sinks, the PDB sitting high on 20mm stand-offs AND the canopy sitting on 10mm stand-offs and a not-particularly-hot-day at 16°C.
For all the blah about the AD-8 HLE being aimed at carrying the Canon 5D I was completely unimpressed by the miserable six minute flight time. As Droidworx and AltiGator unwittingly conspired to screw up my 'brand new' AD-8 HLE order and sent me the 'old' model with 410mm booms I do not have the option of installing bigger props to create more lift. Of course, that may just increase the motor load and make the BL's run even hotter and wear out the batteries even faster.
The basic question here is what is a healthy/safe operating temperature for the BL v2.0?
