Just A Reminder

Just a reminder for myself and who ever read this post. Accident happens! In this hobby its always there waiting to happen while we out on the field enjoying our rc time with friends if we forgot about safety or our mind is somewhere else when we suppose to concentrate on what we are doing.

Night Flying

Flying in the darkness of the night … how the **** we gonna see the plane? We have to see it to be able to control it don’t we?

Sonic Consideration of a Rotating Body

Kwn bukan trying nak hijack thread kat URC http://www.umranrc.com/forum/viewthread.php?thread_id=2726&rowstart=0. tapi considering this is one interesting topic, kwn decide tuk simpan info ni kat blog ni tuk rujukan masa hadapan.

Center of Pressure

Ini actually petikan thread kat umranrc. nak mengelakkan maklumat tu ilang. kwn nak rekod kat sini. Center of Gravity kwn tau, tapi ni Center of Presure. Ape mender tu?

How I Do Things

update 4/29/09 - TX STAND (see end of post)

here i'll share some of my experience and experiment on doing thing in scratch build. you can call it tips n tricks what so ever. my point is just to share what i know. related to depron n coroplast build. you're welcome to share some as well ... just put it in comment area.

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 …

Fuse n CoG

last but not least ... kwn perlukan fuse tuk corostick. so sebab nama pun stick, kwn pun pilih kayu frame tuk jadikan fuse. tapi nak pakai panjang mana ? wing nak letak kat mana? nnt cg dia kat mana? sumer pertanyaan tu kena kwn jwb sendiri. so belayar lagiii (alangkah bertuahnya idup dlm zaman internet nih .... ilmu dihujung jari ).

Control Surface

kwn dah dpt calculation tuk wing corostick. tapi terfikir plak, wing ikut calculation xkan part ekor main potong kot suka hati ja. so kwn make some more research. ni some basic consideration yg kwn dpt.

Dihedral

isu berat kat corostick dah sattle. camne nak tentukan berapa panjang dan lebar wing da sattle.

tapi kat wing stick bmnf kwn tgk ader angle ...  takkan main keapak jer wing tu. so mmg lama dah tau angle tu org panggil dihedral wing. tp kwn xpenah amik tau brapa or mcmana nak tentukan angle dihedral tu.

Wing Aspect Ratio

satu lg consideration bila org nak design plane. (comment kalu salah. please ...)

mende?

wing aspect ratio - nisbah panjang kepada lebar wing.

nisbah ni menentukan respon kapal kita pada roll axis. meaning pusing side to side. kalu slow stick xkan nak roll cam zagi kan?

Wing Loading

kwn idak ler tau banyak sgt pasal rc plane design nih. just basic consideration ja. n atas dasar apa yg kwn nak tau n perlu tau. so apa kwn jumpa masa reasearch tuk corostick rasa syg nak simpan sendiri. baik kongsi kat sini. untung2 ada yg sudi baca.

Adverse Yaw

my build, corostick have teach me a lot on rc plane, more than just flying. with lots of research and asking fellow rcers, is the best way to learn something. here something to share.
