Power System

80% corostick kwn da pun siap. in the process, sedikit sebanyak byk gak info berguna yg dpt kwn gather, not just tuk projek nih, tp jugak utk pengetahuan kwn. so kwn nak mention skali lagi pada flyer2 sumer, ‘sedar x yg kita dah terjerat ke dlm hobi yg cukup interesting?! its not all bout flying …’. kalau sebelum nih kita xpenah amik pusing camner heli copter operate, disbbkan hobi nih sedikit sebyk kita tau konsep disebaliknya (terigt dok dpn astro tgu rancangan ‘a chopper is born’ gara-gara tgh gila heli). kalau sebelum nih xpenah amik tau camner org wat kapal terbang, skg kita sendiri build kapal terbang rc ngan konsep2 yg serupa. what a lucky group of people we are to have found this great hobby …



so … berbalik pada last but not least of my requirement tuk corostick kwn nih. so far aper yg kwn nak, corostick kwn fly grace fully not fast with some extra power tuk pull corostick kwn tu in case of emergency (trust me extra power might save ur plane). kwn research tuk matchkan power plant yg akan powered corostick kwn ke angkasa raya. decided tuk stick to brushless n direct drive.

first thing yg kwn prasan tuk power up plane, kita kena tgk auw (all up weight) plane kita. so lepas congak2 sket, corostick kwn would weight bout 800g – 900g. with some simple straight forward understanding with electric motors (just ikut pemahaman n conclusion sendiri)

kv yg lebih tinggi berikan kelajuan tp xmampu push/pull model yg berat tanpa gearbox. kv rendah untuk slowflight dengan lebih kemampuan untuk push/pull model yg berat

kwn search around, motor dlm 1000kv ngan prop bersesuaian ble pull sampai 1000g (kalu tgk kat ohs yg bagus, depa akan bg maklumat motor ngan thrust, prop n amp drawn tuk particular prop). kwn dptkan satu then matchkan ngan elektronik kat bwh nih:

2 x servo

rx 6ch (da mmg ada)

esc 30a

tx futaba 7c

bty lipo 3s (15c 1550mah, 15c 1350mah)

and its flies … gracefully …

kwn mmg came thru some info yg lebih detail tentang cara2 nak pilih powerplant combination, cam power loading, prop select, etc. tp memandangkan kwn sendiri pun just baca tuk pengetahuan jer, dan kwn xpratik, so kwn rasa baik kwn citer this straight forward method yg kwn pakai. cause it works for my case. tuk further reading mungkin u guys berminat tuk gain knowledge, ble search rc electric power system/plant dlm net.
