The main motor runs too hot. So a little fan was installed in between the rotor shaft and the motor. Notice the black fan and the suspended little motor in the middle......

The new remodification created room for many things to be installed. But one has to resist that temptation if you recall that,in heli world. You pay dearly for an ounce or some little grams introduced.....

Heli on a car....

Here's a video of the heli during the testing of the tail rotor....... It was real aggresive

It's like that tail rotor consumes some space and add extra weight. There is a homemade helicopter that does not have tail

@D Done1
what you see in that video is a tail rotor test,not a lift up test.
The tail rotor does not occupy any space there. It is just at it's home.
That is just the lightest i could shrink that tail rotor to,without having to compromise the structural strength(a vital factor when building air vehicles)..

@Pakingzzz

What size heli do you have (450, 500 or 600 class) and which parts are your major stumbling block? Take a look at the sites below to give you a better idea:

Nice link. Very technicaly educating.
Thanks though. Actualy i have here a 1kg heli size.
The parts that are my major stumbling blocks are as follows: A Tx/Rx,3 Servos,2 ESC,Lipolymer battery,1 Yaw rate gyr and a proper brushless motor.
Although Sidajili has promised to help out with all these listed items. He appears to be extremly busy. So the hope of getting them continues to get thinner. For he might as well have forgotten...
The Tx/Rx i am using to test the heli currently,has only 3 practical channels. And the least number of channels one needs to fly a fixed pitch heli is just 4 channels. So you see why this Tx/Rx aint going to be useful....

Look, if u really want to know if the helicopter is going to fly, connect it direct to a dc supply, maybe on the wall, if it flies, then u kw it's actually going to fly.

If i can recall corectly,there isn't anywhere on this thread where i hinted that i am unsure,if the heli will fly.
It does fly up,but i would have to be holding the tail,owin to the fact that there isn't any single servo there,to give it elevator and airleron control.
So i aint in doubt if the heli will fly. What i'm in doubt is:if Sidajili will keep his own end of his promise.

Suffice it to say that,when you push the throttle stick to around 75% and you hooked a 12v dc to the heli,it hops up and leaps into the air.
Note!! Running such a test would require some one holding the tail. Not unless you want to end up with a premature crash.

So i aint in doubt if the heli will fly or not. What i'm in doubt is:if Sidajili will keep his own end of his promise. He apparently seems non responsive.

Greets Brother! and I applaud you on your efforts! I am a Nigerian/Swede who spent my earlier years in Lagos and Ibadan (1974-1981).
I am an avid RC Helicopter pilot and was just sent this post by a friend who found it on the net! I have now joined the forum due to this! I feel I can perhaps help you in some small ways to get this project and maybe future projects in the air! I am unaware of the postage situation in Nigeria these days but it is worth a shot! Please let me know if there is anything I can do to help my Brother and fellow countryman!

@donskills

Thanks alot donskills... Actually,i would've maiden way back. But i have been set back by a couple of parts,which i couldn't scratch build,as had other parts. These are the parts; 6 channel Tx/Rx,3pcs of micro servos with this specifications(1.2kg torque),a brushless motor(11.1v, 200watt),ESC(11.1V,25Amps),1 yaw rate gyro,a pair of composite blades {(400mm radius)in case my home made wooden blades fails me,due to a crash)}.
Thanks alot,once more.

Greetings Kingsley! There is a fair amount of action on your behalf on HeliFreak if you havent seen it yourself! A bunch of us are working out a way to get you what I presume to end up being a bunch of useful stuff to continue your quest! Can you shop from say HobbyKing etc and be sure to receive the goods? My plan is to get the stuff to Lagos thru someone travelling and then perhaps some financial aid for you to make the trip to there to pick up. I am waiting for word from a fellow Nigerian in the US who travels back and forth to see if he perhaps can help. Any which way, help will get to you by the grace!
Keep up your fantastic work, Naija needs you!

I once contacted hobbyking's customer care. That was some 4 months ago,when i needed a Tx and Rx so badly. I hadn't a paypal so they told me to pay through western union. The enormity of the price has killed for good all hope i had,of succeeding.
I can shop in Hobbyking and be sure to receive it. I have seen their shipping options. It includes Fedex express and Ems express. All these couriers have a branch office in my state.

Thanks alot for your efforts.
Re: Homebuilt Radio controlled Helicopter by maclee(m): 4:57pm On Sep 16, 2013
bro i must really comment on your good work.... thumb ups, you are really good for you to design and build something like this with parts you have at home, you have really done well for urself. even if after building it doesn't work. for the few u have done u have done well. i went through ur pics and saw ur circuits the one u constructed. just in case u are finding it impossible to make it fly, don't be discourage. u can get every parts including the blade (and not the one that will cut u) from arduino stores or u can buy an Arduino UNO R3 board + starter kits. the beauty about it is wonderful things it can do. including programming. I just ordered mine yesterday from amazon at rate of N14,717.69 thats including shipping and handling.
they also sell parts for the heli and car.

check them out

@ Maclee

Thanks brother.
I've read a little about arduino in the past. However,i dont know much about them. But i do know they behave like a computer,by virtue of there programmability. And they stuffs like;taking a certain input/inputs and outputing a certain output/outputs and other stuffs,in respect to what you programmed it to do.
I'll take a pretty look at them.
Anyway,how did you order for the package? As in how did you made the payment. Paypal?

Kingsley, if you can register a paypal account, that will make it easy for us all over the globe to pitch in and help you progress. If you can't (for whatever reason) get a paypal account, I or someone else can order on your behalf and have the stuff delivered to you.
Stay blessed and start brain storming on future projects you might want to attempt too. We will help you make it happen!
