i'm new to RC flying, and i would like to build a quadcopter for some learning and weekend flying

planning to build one that is expandable to octocopter so that when i get good with a quad i will move on and upgrade then mount my DSLR with a gimbal underneath it

planning to get some parts from Rotorbits in Hobby King site so roughly how much budget i should be looking at if let's say i would like to build a medium size quad, then later upgrade to hexa or octo hmm.gif

flight controller should be reusable with different programming and motor also can reuse right? hmm.gif

if u build a simple frame just for flying around ... it costs less than rm10 for the frame
just dump the old one and build a new one when u upgrade ... hahaha
most controllers that can fly a quad can handle an octo
motors and escs ... just get another 4 of the same ones when u upgrade to octo from quad
*
is there any local sellers/shops i can get those parts like motor, propeller flight controller etc etc?

shipment from Hobbyking is kinda expensive (EMS is around RM50 under 1KG) since i'm planning to build bit by bit

carbon fiber is extremely expensive
aluminium u will have to source around la ... google is your fren

yes ... even after accounting for shipping ... alot of stuff still cheaper to ship in yourself
*
i can find some carbon fiber tube from HobbyKing that is way lower than ebay and their weight is light so i think shipment still ok la

wanna ask if the rotor boom i use 12mm thick hollow carbon fiber tube for octocopter, 14" props will it be too much stress on it? hmm.gif

want to find those motor dataspec also very hard, not all motor got data, worry later i buy wrong icon_question.gif

lipo batteries are very hard to ship by air. some couriers ban them totally.

but the seller already mentioned free shipping with china airmail, the thing is do i need to do anything on my side? like settle the tax and so on?

any wire that handles 2 or 3a good enuff la ...
easiest to use the jst connectors ... light and secure connection

thank for the recommendation, for the connector i've decided to go for T style dean plug

it is really hard to get the ampere draw for those gimbal motors

gimbal motors draw so little ...
but nvm la ... deans works .. just add little more weight only .. LOL

weight not really a matter here, since i'm building a handheld gimbal only and the gimbal is already full carbon fiber, the only aluminium is the clamp, gonna abandoned my multirotor plan due to its cost and i think malaysia is not really a RC plane friendly place

to fly RC planes .. need big open space
if in klang valley then really not ez

multirotors are getting cheaper by the day
prolly coz no need big space like plane ... hahaha
*
quad is cheap, but hex or above starting to get more expensive, and lesser flight time, at first thought of building an octo that can carry a dslr to do some aerial photography but that is too far off from my budget

kinda hard to find workshop or factory that produce carbon fiber and custom cutting in malaysia, anyone know any carbon fiber maker in malaysia can recommend me, next time want get replacement part also easier tongue.gif

end up i have to source the carbon fiber from china which cost me around USD 150-160 for all the parts in the picture above, it is 3k carbon fiber, cutting is good so it is quite worth the price

anyone want a 6s1p battery? i tried to purchase a 4s1p battery from alibaba but the lousy supplier sent me a 6s1p battery instead vmad.gif , the battery is working fine

who need it can offer as i cant use 6s1p for my gimbal, i havent use it before, only plugged it to check the capacity and i store it in room temperature with lipo guard bag

and the thing is the stupid seller go stick the wrong label on the battery, so i dont know what is the actual mAh, but initially i ordered 4s1p 8000mAh, below is the picture

i need help on choosing a radio control to remote control my camera gimbal, it is a handheld gimbal so it will only be short range probably 50 meters

is there any 4ch radio control and receiver suitable for low budget people like me? hmm.gif

is there anyway i can dispose of my 2x 10000mah lipo battery?

i heard of discharging it using lipo charger or the messy salt water method.

but i want to know whether there is some kind of facilities/factories that accept disposal of lipo battery? hmm.gif

Fresh water oso can..  It just takes longer time only compared to salt water..
Soak in fresh water for a week compared to 1 or 2 days in Salt water..  Same effect..
*
but after that the salt water will be corrosive? so i must do that in a steel or glass container? since plastic is no good for corrosive liquid
