I just got a TDR, it's used but cared for and in practically new condition.
The motor installed is Scorpion HK 4530-540 LE which I think is overkill for me.
The ESC is Robbe Roxxy 120HV, which is specced at 150amp peak. WR Bec and VBar governor, headspeeds 1450-1850.
At the moment I am seriously thinking about swapping this motor for a pyro-52 or a lesser scorpion (HKIII4035-560), for a couple of reasons.
I have no plans to smack this TDR around, not really interested in beating speed records as well, also I think this ESC may not be up to the task in some extreme conditions, as this motor can draw 250amp for 2 seconds. I also don't want to put unnecessary stress on the heli power drive (I don't think it was designed to handle 10k power systems without accelerated tear and wear)
