hi guys, been flying and building for a good few years now.
i was out of the air for 2 years but now im back up and flying again, missed it alot, all of my previous builds were modded versions from bought frames,

i had a Hj H4 Folding carbon fibre Quadcopter frame from ebay and built ontop of that.

from a friend for a very cheap price. a fraction of what it retails for from

its a stable platform but i think i overloaded it with weight from fpv setup and gimble , it resulted in a crash on my last flight

This altitude play Ended VERY badly (4 min 23 sec)

whilst out flying the other afternoon , my h500 quad decided to go awal for no apparent reason , it switched itself to LAND , i had minimum stick input for roll pitch yaw, and had zero throttle control. using the telemetry link and mission planner i tried to get it out of LAND mode back to stab but no ended in a tree with broken arms, props, and landing gear,

so NOW ONTO THE REBUILD /UPGRADE ! >> more to follow after this post !

The Build Begins

ok so onto the build,

here I have the damaged h500 frame from droneshop that crashed,
it currently has 810kv rc timer motors, spinning a 1245 prop , these motors are designed for 1045 , but for some reason my friend used 1245 and it handled fine,

as you can see I have the 13 inch carbons going on ,
the NEW arms that are going on are 33cm long .
compared to what is currently on in this photo (17cm)

Description: width
measures in at 1000 size ,
or 850 if I trim the arms so the props only JUST fit without overhanging the frame

I don't want any overhang of the props/frame as I want it to be as efficient as possible.

oh look! heres the postie... brang me my new DJi E800s from buildYouOwnDrone

Multirotors are models too!
Just a curiosity for future builds. When using round tub arms, how do you make sure the motors are level, and how do you keep them level??

put the vehicle on a flat table,

install the props ,

get a set square [roofing square] lay it square to the table surface , measure the to the tip of the prop , spin the prop to the other tip of the prop , measure.. ajust motor until both measurements are equal,

put a bit of lock tite thread lock gel around the tube clamp edge and all over the tube clamp screws and bolt down checking constantly the measurements are perfectly matched when turning the props

once the threadlock dries it should keep it pretty stiff,

SHE measures in at a healty and SPOT on 850mm
thats around 1000mm with props on .

i am going to be replacing the STOCK legs with wither some Short aluminium Feet mounted to the corners of the frame that will just keep the gimbal and battery underneath clear of the floor.. as i dont like it to high up ..

OR depending on my flight time.. maybe some tarot RETRACTS

all up weight, loaded with gimbal , cameras, fpx tx , (basically everything) AND a 4s 5200mah battery

is only 2.39 KG

BUT this will run on a 6s 5200mah ,
and that will be my next update.. batterys !

i shall be breaking down 3 lipo batterys to bare bones ,

and creating 2x 5200mah 20c lipos
