Sidajili: Any Nairalander out there building and flying RC rotary or fixed wing Aircraft models of any scale? Lets discuss and get this thread going.

That's nice. I am actually building an RC helicopter. With an onboard video camera,capable of remotely taking up to 100 pix,and 10mins of video length. Here's my project. www.nairaland.com/1307261/homebuilt-helicopter

CONTINUATION

SAWING OUT THE (SEESAW BLADEHOLDER) OUT FROM THE SHEET!

CHISELING OUT THE SEESAW HINGE

D Don1: It won't fly, u need a special motor, and the body must be light weight

i have done that experiment in 2012, and it lifted a weight of 900gms up. What dissuaded me was the fact that i used toy car remote control running at 100Mhz and a homebuilt servo,which i constructed using a wall clock innard. They happen to be very slow at response. I understand you need a special motor,ok. That's far-fetched i guess. But you can turn any useless motor into a special one,if you have the know-how,and that's no skin off my nose. What was real work enough was,constructing the rotor head system out of aluminium sheet,and make them symmetrical as can be.

CONTINUATION OF THE FABRICATION PROCESS

I have many quartz crystals lying around,but they are tiny tiny ones

Raymondenyi: Wen u done, let me know; by d way how can I help?

you can help me with any laptop battery brand. Thats what's going to power the heli. The one i have is deteriorated.

THE FABRICATION PROCESS

Here's the full documentation of the work so far on the homebuilt helicopter.

My name is Kingsley Obinna, Aka Pakingzzz.
A student of Michael Opkara University of Agriculture. Currently studying Mathematics.... Enough of the introduction about me...

[color=#110300]I am currently bulding a homebuilt radio control helicopter...]The helicopter weighs 950grams including the battery. [/color]

One problem most people often have,trying to building a pratical model helicopter is: the ability to get certain critical parts....
I want to show them how to bypass that.
If you want to bypass my method,then you must have some sound idea about design ideas,design theories,design problems,mechanics,fabrication and having an idea of material structural strength.

In my design,i am using a model Airhogs bluesky airplane Tx and Rx.
The Tx is a 2.4ghz,and has a micro camera embedded in the receiver.. According to the manual,it could take up to 100 pictures and a 5 minute length video.

---

The Tx functions just like a mode 2 Tx,where the throttle is on the left and aileron is on the right.
Each joystick has one axis of movement(an unusable feature for heli control). So i disoldered it and replaced it with a Playstation joystick. I did this that i can have a joystick with 2 axis .
This airhog Rx was built to drive a micro motor that ran at 3.2v,and drew 1amps.
I wanted it to drive a motor that draws about 15amps at 12v with it. I knew this impossible without destroying the mosfet in the Rx.
I simply built an amplifier to amplify the 3.2v to 12v,and the current as well.
I also buit a little Bec for the Rx.

---

At first,when i connected the Rx to the Bec,it wouldn't pair with the Tx. I suspected there where alot of interference coming from the main motor,and disturbing the reception. I soldered a diode to the output of the Bec and the problem was solved.

THE MAIN BLADES

---

I built the helicopter blades, from a strip of baton board or ceiling batton stick,(i dont know what you call yours).
It was hand carved. You have to have a ton of patience doing this,and love it as well.
Mind you,these batons are unsymmetrical in their dispersion of weight. You would have to balance your blades statically and dynamically,else your heli will never fly.

---

---

As with the blade, all other parts are mostly custom built.
The construction of the blade holder or rotor head,was done,using light aluminuim sheets.
