I have started building the heli right away!

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:27am On Oct 19, 2013
More to come

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 3:12pm On Oct 22, 2013
Am almost through with the heli.

Wow i managed to follow this thread from the begining and I'm so so impressed nd inspired.the most inspiring thing is Τ̅ђat U̶̲̥̅̊я̲̣̥ studying agriculture and this is coming from u.another thing is the donations from britain,those made me shocked.bro plss take this to U̶̲̥̅̊я̲̣̥ HOD I'm vry sure U̶̲̥̅̊я̲̣̥ skool and department would be so proud of u.nd we neva can tell this may be included in the skool library...#cheers



Plsss I'm so eager to see it fly! Try to post the video here cos people like me Τ̅ђat can't watch videos directly from youtube

@toms55,

I am not studying agriculture. I am studying mathematic. wink
Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:02pm On Oct 24, 2013
I needed a variable pitch tail rotor. But i hadn't the main parts. I decided to apply a system i call; combination... In this method,i try and combine different parts from different sources,so as to achieve my aim undecided
Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:07pm On Oct 24, 2013
First,i started with cutting an aluminium rail,used to hang curtains at home. Then i bent it to shape,and drill the required holes,as worked out by me

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:13pm On Oct 24, 2013
Next was the inclusion of the bearing bearing holder.. This was made by cutting in half,a Trex 450 flybar seesaw holder,and turning one half 180 degrees,to still face the other half.

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:19pm On Oct 24, 2013
You would wonder why the aluminium railing?? cry
Yeah... It is actually there,to connect the bearing holder to the tail boom. grin

Nice work. Hope this work of urs will lead to papers showing how to build inexpensive helicopters. Knowledge never dies when it's shared hommes. wink

The tail drive are bevel gears

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:47pm On Oct 25, 2013
To make the tail blade push rod,i had to modify a ball joint linkage rod...
My aim here was to convert one end of the ball joint into a bearing holder..
I started by enlargening the hole with a round file.

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:49pm On Oct 25, 2013
Here is the modified ball joint,housing a precision bearing

Re: Homebuilt Radio controlled Helicopter by Pakingzzz(m): 9:56pm On Oct 25, 2013
Below is the linkage rod,connected to the tail rotor blades. They move left or right,thus changing the pitch of both blades.

It was donated to me from Britain. Re-read the last page. I documented it there.

I just finished building and setting up my helicopter today,including programming the Transmitter.

I had my throttle curve at 0,25,50,60,60... The spool up was awesome.. Being my first time,i had to take it easy on the throttle stick.so i decided not to go over 60% throttle.... I am still trying to concentrate on the throttle and rudder..
Due to limited resources,i had to construct the shaft driven variable pitch tail rotor system from some local materials.. I ended up having a tail heavy helicopter... You won't believe this... To compensate for that tail heaviness,a 2200mah lipoly with ratings 3s 1p was placed on the nose,alongside the main lipoly that powers my heli.. It still had more power to lift off at 75% of stick input.. I shall post the videos shortly.

Here's a video of one of my spool up. I was a bit hard on the throttle,so the heli shot up into the air! In a frantic move,i hastily reduced the throttle,and the heli slammed down hard on the floor,bendind one of the aluminium struts holding the landing skids.
