You are slow close to eliminating that RX-18.
Big dreams I know, especially considering different hulls, but I'd love to see that all in a case that just plugged into a multi pin header. Kinda of like the B9 Robot's power pack. I know if you went all servo turret functions (which would make sense with HL or Mato), all you would need would be ESCs, right?
Hot hot does the amp get? The 6W got pretty warm, but this one seems to have a better sink.
