Systema gears?
Hello!
Im about to upgrade my G&P M4 (8mm gearbox)
The spring will be Guarder 120/130 , M160 motor, beaings spring guide and 11.1 1300mah 20C battery ,prommy barrel, Systema + scs and all the rest is stock.
Now I just wonder what gears should I get?
Systema Original ratio or Torque up? Im talking about the flat gears...
What is the hotest spring that the original ratio can handle?
Thanks
