Igikorwa nyamukuru nugutwara umutwaro no gutanga ubuyobozi nyabwo bwo kuzenguruka hub. Ifite imitwaro ya axial hamwe nu mutwaro wa radiyo. Ni igice cyingenzi. Imodoka gakondo yimodoka igizwe nibice bibiri byerekana imashini cyangwa imipira. Kwishyiriraho, gusiga amavuta, gufunga no guhinduranya ibicuruzwa bikorerwa kumurongo wimodoka. Iyi miterere ituma bigorana guterana muruganda rwimodoka, igiciro kinini kandi kwizerwa nabi. Byongeye kandi, iyo ibinyabiziga bibungabunzwe aho bibungabungwa, ibyuma bigomba gusukurwa, gusiga amavuta no guhinduka. Igice cyo gutwara hub cyatejwe imbere hashingiwe kumpande zisanzwe zifatika zifata imipira. Ihuza ibice bibiri byerekana. Ifite ibyiza byo gukora neza guterana, kureka guhinduranya ibintu, uburemere bworoheje, imiterere yoroheje, ubushobozi bunini bwo gutwara ibintu, amavuta yo gupakira mbere yo gufunga ibintu, kureka gufunga hub hanze kandi nta kubungabunga. Yakoreshejwe cyane mumodoka, Ifite kandi uburyo bwo kwagura buhoro buhoro ikoreshwa ryamakamyo.
