MJX F45 brushless at Dato Onn Flying Field

May i present for my youtube video section

 
is about my first try to fly the MJX F45 brushless setup at Dato Onn field , test her performance on wide open space..

FPV MJX F45 for the First Time

Finally i manage to build and make a simple FPV. which i will release  a simple review and tutorial how to connect and powered 5.8ghz Video ...

Right now after i attach simple keychain camera, i wish i had a live feed view from my MJX F45 helicopter so i buy a cheap 200mwatt video transmitter and receiver from my friend ..the question is can my MJXF45 can carried my camera?

After several searching for information how many weights do MJXF45 can carried . i read a forum post says that it can carry gopro camera weight about 100grams, so i buy a very light 3cell lipo 360mah ..and put all electronic including camera and battery...guesst what ? it weight same as GoPro Camera about 100gram also

Now i build casing for my VTx( Video Transmitter) put it at a below my helicopter and patch it fiber tape..and fly it first to see if my copter can carried it ..after all my heli is now brushless n lots of power.
After a while hover my heli with camera it seems no problem.

So i decided to bring my FPV equipment such as google, video receiver and FPV helicopter to field beside my house ...this is my first time to fly FPV style ...seems very odd  but feels gread ..i manage to hover it but seems quite difficult fly with limited view..i will try to fly it again soon 

My MJX F45 brushless conversion build

Finally after several weeks and days reading from RC Groups forum, i finally decided to convert my main motor to brushless one, i know its only fixed pitch helicopter but i just wanna  mod and try something

In RC Groups forum the suitable motor to convert brushless is EH 200 and for pinion is 10 teeth

this is the pic of the motor and link from hobbyking ]

 For list of other parts

Hex screw

Pinion 10 teeth
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=11198&aff=447355

ESC 18Amp
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=4312&aff=447355

for connection, just put the ESC servo connector to extra slot infront aileron n elevator servo slot in MJX F45 pcb board and for powered the esc, solder positive n negative esc to PCB board +/-wire

after done assemble, carefully reroute wire connection so it can fit canopy

now for hover test

How our GPS coordinate is determined

What is Trilateration?
The measurement of a series of distances between points on the surface of the earth, for the purpose of establishing relative positions of the points in surveying.
Trilateration is a method for determining the intersections of three sphere surfaces given the centers and radii of the three spheres. huerm....... my gps device so brilliant... math-power.....

See this diagram.....


We start with the equations for the three spheres





and



We need to find a point located at (x, y, z) that satisfies all three equations.

First we subtract the second equation from the first and solve for x:



Substituting this back into the formula for the first sphere produces the formula for a circle, the solution to the intersection of the first two spheres:



Substituting : into the formula for the third sphere and solving for y there results:



Now that we have the x- and y-coordinates of the solution point, we can simply rearrange the formula for the first sphere to find the z-coordinate:



All this calculation has been made and use by our GPS to do tracking
