first you will need to get all your electronic as follow

you will need

3 x motor 700kv to 850kv no bigger than 30mm" with prop mounting shaft
3 x gyro similar to the futaba gy401 or kk board
1 x gyro a good tail gyro of your choice for the ruder servo
3 x 12 to 18amp ESC or 30amp if you are going to put load on it
1 x futaba 9650 servo or any good tail servo,

a futaba radio is great choice because you can split the gain into different channel or the motor will fight each other if they all run in heading hold mode this'll make the craft unstable, If you a spectrum user you will need to get the kk board: because you will not have the advantage to separate the 3 gyro gain from the tail servo gyro gain, you can find a kk for $25 up to a $100 dollar

I'll upload some pic shortly and how to get started with the frame

Watch at YouTube

you will need 2 of these it plastic very strong like carbon fiber you can use electronic board- fiber glass material i got this from mcmastercar,com it sell by the foot/inches it less than 1mm thick

it can be circle square no matter i use a diamond shape
it 5 1/2" each side i make a half of a diamond mold first place the wood and then make the hole then use it to make the original frame

[url=]

this is the camera battery mount it's 7 1/2" LGH and 2" width

[url=]

This is the bottom frame mounted it to the camera/battery tray
i use 2 colegate cover as spacer as shown here

[url=]

[url=]

i buy a pice of wood from home depot 78" divided into 3 it doesn't have to be this big you can use 36"/3 no matter you can start small for your first built, the size wood is less than 1" wide so 3/8 of an inch all 4 side use a drill to make the hole in the wood no nail
use flat head screw 25mm LGH 3.30mm WGHT 6x40/3/8 the flat head screw
must be level with the frame use a special drill bit to widen the top of the frame and it will not make the bottom of the hole bigger i forgot the name of this drill bit

if the top of the screw is sticking out of the frame it will lock tight onto the wood you can see below

[url=]

the 4 hole in the back of the frame when you insert the the screw it must lock closely to the wood so the wood can't move side to side then fasten drill the wood for the front make hole even don't over tight because the arm need to fold for easy transport as shown below

[url=]

next upload will be motor mounting and electronic setup have to do a little at a time, just be patient with me,

Watch at YouTube

look how stable it is now,

The new copter much lighter than the on on the top

this the y-arm and motor mount

2 piece of rubber and zip tag is use to hold camera mount

A good gyro is needed for the tail

the is flybar taken from the mini titan 450 this will use for yawning
the motor is strap to it using zip tag the is a good and simple way
to get the tail done,

This how the gyro is laid out the 401 will control the tail servo
the other 3 gyro must set on there side with wire point toward the motor a gyro that sit on the bottom is to counter effect movement
left/right so since the motor are standing upward the gyro have to stay on there side to counter effect the falling of the y-arm;
the gyro detect an altitude change in the motor and increase or
decrease the RPM to keep the arm levle,

gyro setup
all limit set to 0 counter clock wise CCW
digital set to off
delay set to

separate all the gain wire for the 3 gyro and solder them together and plug them into the channel 7 on the RX then assign that channel to the nab on the TX all 3 motor need to run in rate mode
connect the tail gyro to channel 4/5 just like on the helicopter

[B]Any gyro can use
if the gyro stand on it side to fly a helicopter.
it have to lay down flat to fly the y-copter

ESC and motor connection and trouble shoot next i'll fly this one tomorrow if not too busy

I was waiting on some honey but there aren't no Queen bee,
