I'm a football enthusiast. Been following this thread albeit keeping a low profile. I must admit that I'm amazed by the intelligence and maturity displayed by members on here. Have decided to come out of my shell and become an active member here. Welcome me guys!

RCDIY:
So, like earlier mentioned, we need some parts to make this build happen.
I have decided to make a small quadcopter of 250mm size.

Lets discuss the various parts required.

Frame
The frame is the chassis of the quadcopter. On this chassis, every other component is installed (Motors, ESCs, Flight controller, etc).
There are many factors that can influence the choice of a frame. These includes
- Size of quad
- Purpose
- Payload
The choice of frame will determine what motors and propellers you'd use, what size of battery it'd run and the amount of gear it could carry.
Once you make up your mind on the frame to use, you can move onto the next thing; Propellers.

Propellers
Propellers are determined by frame size first before load/thrust care considered. This is because the frame span can only accommodate propellers of particular size to avoid them touching while spinning.
Other features to be considered while choosing props are diameter and pitch. We will discuss this better much later.
When you're done selecting the propellers based on frame size, you'd need to pick your motors.

Motors
Motors are the engines of the quadcopter, spinning the props with instructions from the flight controller to lift the craft.
Motors are classified based on Stator size and KV (KV refers to the rpm constant of a motor - the number of revolutions per minute that the motor will turn when 1V (one Volt) is applied to it with no load attached).
There are standardized charts available online showing motor types/sizes and propeller combination.

Electronic Speed Controller
ESCs interprets the PWM signals from the flight controller or radio receiver, and drives the brushless motor by providing the appropriate level of electrical power. They are rated in Amps (A).
Choice is determined by the estimated maximum current drawn by each motor at full throttle (measured in Amps)
The rule of the thumb here is to choose ESCs with ratings well above the maximum Amp draw of your motors, else failure becomes inevitable.

Flight Controller
A flight controller (FC) is the brain of the aircraft, which is basically a circuit board that has built-in sensors (Gyros, Accelerometers, barometers) that detects orientation changes. It also receives user commands from a Receiver paired to a Transmitter, and controls the motors in order to keep the quadcopter in the air.
FCs are of different kinds usually distiguished by features and capabilities. Cost is also a major maker; the more sophisticated, the more expensive.
While all good FCs can take a quadcopter into the air, the level of control achievable depends on the design of different FCs.
For instance, a NAZE32 FC acro has no kind of computer assited flight like self leveling. The pilot is essentially responsible for ALL control using inputs on the transmitter.
Other FCs like NAZE32 (10DOF), KK2 and Naza can do self level flights. The Naza, using GPS, can achieve amazing stability in the in 3D.

Transmitter and Receiver
These are as their names imply. The transmitter is used to send commands to the FC through the Receiver which is mounted on the Quadcopter and connected to the FC.
Common TX/RX use 2.4GHZ radio band.


In the next post, we will look at the components chosen for this build and possibly discuss them more.

Questions are welcome.

Good day Sir. Could you give me the estimated cost of building a 250mm size quodcopter (from ordering of parts to assemblying/completion)

Happy New Year

Most churches will relocate their headquarters from Lagos inorder to reduce tax burden. MFM, deeperlife, Synagogue, Trem...

But I'm curious, how will the income be determined, because churches won't disclose their income

estimated tax i suppose

I will die single.

Are you kidding Sir?

but they've not ended SARS.

Funny how this guy is gradually attaining that celebrity height effortlessly. If I should flag off a campaign against corrupt parastatals, I barely have followers to retweet them.

SuperSuave:
A very long way. Are you an atheist?

a Christian Sir

SuperSuave:
I always doze off whenever they're talking politics

not a political savvy per se but american movies that tend to portray american politics have a way of arousing curiosity in me. i see myself inadvertently trying to distinguish as well as making comparisons as it relates to the stomach infrastructural politics we witness here. we still have got a long way to go

shugacane. come and share

SuperSuave:
seriously? I've stopped watching it after seeing episode 1 of S02. The series is more of political talks than action, I miss Jack Bauer of 24

those political talks and puzzle intrigue me brother

Designated survivor. Godamn it. that movie is as lit as F**k

Richie0974:
Oh really!!! I'll prefer it to Nigeria still.

you've got a mail Sir

op. buy mycothen cream, apply morning and night after bath. share your testimony after three days

Funnicator:
5mp789L. please help me critique.

your games contain elements of upset in them. i wouldn't stake that high on such selections. not saying I'm a pro tho but punting wise, I would rather pass. best of luck should you decide to proceed with your tips brother

was this meant to be funny? ?

you obviously didnt get the gist

adobuz:
Na 10k I get

No Ma.

adobuz:
You go take 10k?

I've got one for sale. I'm selling 30k with the "follow come" acessories

pls guys,, it just started raining this evening and a match which i have relished watching has had its channel scrambled. endeavor to drop updates as i bid to keep abreast with live match actions. KTBFFH. optional1, i sight you blue baby

.....ik road is okay and close to school too.

oya mek we pack in go there

shugacane:
lol. even for this my side cultists dey disturb sometimes. this uyo boys that dont have hand work only to join cult that they know. i think u should relocate to relocate to somewhere far. maybe eket

, even your side? .... na him be say no where safe for uyo be that. i have friends who stay around IK road and according to them, it's safer there. aka road and abak road are also safe.


babe you like me one bit. you no even get little joy for me. you wan mek i relocate go eket. na him be say i go gradge for 900L

betis scores and its all over
