Cool, thank you. Also, are these rebuildable like the Novak Ballistic? Also, I haven't heard of the Tekin 13.5's being faster than the Duo2's or Ballistic's. Apart from trying all three, what's your take?
It would be great if manufacturers stepped up to the plate to provide consistent data, like the Nitro engine manufacturers, which provide RPM and HP.
Epic Duo2 13.5
RPM: 3402 RPM/1.0volt
Power: 7.62 watts/1.0volt
Torque: 116.8 Nmm
Novak Ballistic 13.5
RPM: 3300 RPM/1.0volt
