I,ve a heng long tiger one and I,m waiting on a rb from Stevie welsh dragon does anyone know if it comes with an Ariel wire attached, also I'm planning to upgrade what I think is the recoil switch ,is it the one that comes off the left unit ,midway along the top line of the rx18 into the turret two wires red/black to a flimsy looking switch if so can I upgrade.it has already came off so I soldered it directly to the wee plates ,hope this makes sense.
