HELICOPTER,over!!

pheewww...
realised I forgot to tell about my Heli
so,the 1st assessment was on Monday
the 2nd and the final flight testing was on Thursday
on Monday,our li'l heli didn't perform well
in fact,we kept working on it till sien liao
So we in fact named it "Poyoh Hitam"
(note: poyoh--informal which means lagak/sombong/banyak kerenah)
courtesy of my malay groupmates

til Wed nite,
it did even worse
the motors' efficiency dropped
coz maybe we keep testing with it
so perhaps it overheated etc..
Actually we overpowered it ler
Our battery supply is 12V (from motorbike wan)
our motor can only support up to 8V
then lazy use regulator--coz we already spent too much
but end up burning two motors..which is worse
Long story...
so on Wed,instead of thinkin how to improve it
Me and chanling beautified it instead
colored the whole damn heli into black
then towards the evening
since we've been doing it so long d
might as well go all the way
giving up is too late

So i retied the fuselage
looks like all the years in joining Girl Guides came in handy
apparently I was the only one who knew square lashing,ehe
coz' before that,the body is too wide
so the moment is too big,and made it too heavy,bla bla
all the theory stuff
then made it smaller
and we experimented till 2am
everytime we tested the motors
it heats up very fast
so we have to let them cool down about 10mins
of course, we entertain ourselves silly
luckily my groupmates all quite fun
ya,we changed its wiring to parallel,so the motors wont burn
before that it was series
but till 2am the heli like still gila-gila
so we really "mou ngan thai"
and closed session

the next morning
our group also quite demoralised
coz' we heard the other 6 groups' heli were superb
some can even go up to 2meters
ours barely made 30cm
our lecturer wanted to test on
Take-off,landing, hover, forward flight
ours was group 5
SURPRISINGLY, altho ours hovered very low
and its forward flight even lower
the lecturer seems to approve of it
even our avionics/vibration and control lecturer turned up
so he also became the judge lor

We also mulut ternganga
coz really first time see our heli fly so well
but as long as we can ngam ngam reach lecturer's requirement
also very the happy dee..
Maybe because ours couldn't go high
we didn't even have to control it with thread or rods
(which other groups use)
coz theirs is very imbalanced and unstable
they had to pull it down to hover,etc
ours just hovered nicely at the bottom
haha~
in our hearts we thought
"mampus ah kali ini, sial betul heli ni #%#*&^^& "

after that
the lecturer announced winners for two categories
"best architecture" and "best overall performance"
we actually placed 2nd for both categories
we were like, "HUHHH???"
we were subjected to glares of resentment by some groups
maybe they thought since ours could barely fly
but both lecturers says our hovering and forward flight very good wor
and maybe the heli in black looks good kua...
so the height didn't matter I guess
basically,our group's heli had the proper concept instead of flying blindly
the group that won both categories were very good though,
its design is very special
Haha..we were very happy
Celebrated with KFC that night
Yay...but now have to do the technical reports lo..
Wait la..I upload the pix later k
Long live Poyoh Hitam and Gagak Hitam!!!
(P/s: Gagak Hitam is us..or Gagak Merah la..
On monday our groupmates wore black,then on Thurs we wore red)
