Ubufakazi bokuqhuma kwe-Shenhai
I-IIB kanye ne-IIIC zombili zisebenza njengezigaba zamathuluzi kagesi angaqhumi ezindaweni ezinothuli, enezinga le-IIC ngaphezu kwe-IIIB.

Ezimweni ezihlukaniswe njenge-IIA, IIIB, noma IIIC, Izindawo ze-IIC zibeka engcupheni enkulu. Ama-servo motors angaqhumisi we-IIC afanele ukusetshenziswa ezindaweni zothuli ze-IIB, kuyilapho amamotho e-IIB engahloselwe ukusetshenziswa ezindaweni ezinegesi.
Wonke ama-servo motors angaqhumi ahlukaniswa njenge-IIIC, ukubenza bafanelekele uhla lwezimo ezinothuli.
