Nice videos, I wanted one of those motors back then, the word was those was the fastest brush 6 to 8 cell motor. Have you seen the leopard 2860 or the 2860 size motors perform, I don't think that motor would beat the 2860 size motors of a comparable kV. I can tell you from experience that the 2860 is some motor. I ran a Rio ep with the 5050kv on 2s spinning an octura m435 3 blade. The motor had the boat over powered I couldn't believe my eyes, well the power of that motor ring the 1/8 flex shaft in quick order.
