He rereke te tohu whakaatu mai i te 800 ki te 2200 mo te huringa raina o te huringa mahi i roto i te awhe. Ko te huri i te potentiometer i runga i te kaiwhakahaere PWM ka piki, ka whakaheke ranei i te putanga PWM.
Hipanga 5: Hononga tauranga motopaika:
Tūhonohia ngā kāpeka motini ki te Wāhanga A, B, me C. Ma te raupapa e whakatau te ahunga o te hurihanga o te motini. Ko te hurihanga e hiahiatia ana o te Drone he karaka ka titiro ki roto i te motini kia kore ai e matara te poroporo. Na reira he mea nui ki te whakau i te ahunga hurihuri i mua i te whakapuru i nga matatahi. Homai he tohu tohutoro PWM ma te takawiri i te potentiometer i runga i te kaiwhakahaere PWM ka timata me te iti rawa o te tuunga whanui puihi (800). Ka timata te motini ki te hurihuri i te 7.87% huringa mahi (50Hz) me runga ake. Ko te whakaaturanga Waahanga 7 e whakaatu ana i te 1573 (7.87% huringa mahi) ki te 1931 (10.8% huringa mahi) ka huri te motuka. Whakaūhia te ahunga o te hurihanga he porotiti. Ki te kore e huri i nga hononga e rua ki nga kapeka motopaika. Whakahokia te potentiometer ki te tautuhinga tere iti rawa.
Hipanga 6: Whakapiki i te Propeller:
Momotu te mana pākahiko. Whakanuia te mata poroporoaki ma te wiri ki roto i te karaka motopaika ki te anga karaka. Kia mau ki te pupuri i te rakau/motoka me te totoro o te ringa me te noho matara mai i nga arai me nga tangata katoa i te wa e mahi ana. Honoa te hiko. Ka kaha te mahi a te poroporoaki ki te ringa i te wa e huri ana, na reira me kaha te pupuri kia kore ai e whara te tinana. Takawirihia te potentiometer hei huri i te tere (ko te whakaatu i waenga i te 1573 me te 1931) Ka oti te whakaaturanga.
Ko te pikitia i raro nei e whakaatu ana i te tatūnga waea katoa mo te whakaaturanga.
