Iimodeli ze-GCM ikakhulu zeplate ye-radiu radriu charferng kunye nodidi lwe-Betarfer of Gemplering kunye nohlobo lwe-Auto ohambayo kwiplate i-4-80mm, ifumaneke ukwenza i-R2, i-R3, C3 radius. Ukuba ne-Possil GCM-R3T, GCM-R3TD, GCM-R3R yenketho kunye nokuguqula kunye nezisombululo ezenziwe ngokwesiko.
