Reptile Style 800 Size 6s Quad

photo73360081981384774

Recently I got myself a TBS clone quad frame kit from a friend so decided to try a 6s quad, I have a new Pixhawk from goodluckbuy at my disposal so might as well test it out

Specs!

– Frame TBS style with RCtimer S800 Arm
– Rctimer 5010/14 360KV Multicopter Brushless Motor (5.0mm Shaft)
– 14×5.5 Carbon Props
– 45A multistar ESC opto
– Pixhawk with neo7h
– 2200mAh 6s, it 2200mAh 3s in series will try 3000 later
– Rangelink LRS with FRSky Taranis
– 3D Printed Gimbal for SJ4000

S800 arm from rctimer are suck, if you plan to use it make some mod on it, I removed the brass stub that hold the screw and take a 3.5mm drill bit make a hole from top to the bottom (will post picture later), and take a M3 40mm screw to fasten the arm

Initial flight was fine but had a crash when trying autotune for first time, most probably my mid throttle are to high (500), the Quad only need around 30% to hover at 8A!

Turn out the issues with the motor and esc combination motor getting out of sync so I ordered myself 5x these

thanks to rcgroups for suggesting the esc to me

It almost crashed the second time but my good reflex save the quad from kissing the ground again

I get total 7min with 2200mAh 6s on this test will try 3300mAh next time and maybe 5000mAh 6s

Hopefully I can get the ESC before weekend so I can test it again with the new ESC

Hobbyking X550 Build log

This is my X550 from hobbyking build log, cheap frame made out of fiberglass plate with aluminum arm, to be honest all the part is cleanly cut as promoted the only this is lacking are “assembly manual” took some time for me to figure out how to assemble all the thing but still fairly easy to do so here is my pictorial build log

Source: www.hobbyking.com/hobbyking/store/__24151__Hobbyking_X550_Glass_Fiber_Quadcopter_Frame_550mm.html

This is all the part come with in the box not much :)

 

as i mention earlier there no assembly manual what you see what you got, i wonder what we going to do with this bunch of screw, oh ya you will need HEX for all the screw!

So let start with the Arm, straight forward procedure insert the screw to the hole :D

do it with all 4, remember do not fastened it to tight if you want to fold it, if you dont have any plan to fold it just tighten it as hard as you can :p,

Note: good thing is all the nut are nylock!

do the same for Arm sorry i forgot to get the picture for arm landing skid so I skipped to the finished build T_T

Test fitting my DT750 motor

frame folded

The frame can take prop size from 8 inch to 12 inch i think as I tested with 11 inch still have some space left

frame weight with out electronics

some few problem might to take note of when folding the frame

extra nut and bolts?

Battery strap come with the frame

 

UPDATE (20/05/2012)

As Peter request this is how I mount my DT750, I used stock mount I’m using M3 Screw for it, but you can’t use washer on top part you can only use at the bottom

PS: will not use DT750 for this frame to motor heavy I start sourcing for a new motors, not that this DT750 not good but I wont be doing any heavy lifting yet, for sport flying the motor is and overkill

so conclusion

PRO:

1. frame is cheap $19.99 usd

2. Arm can be replaced with any aluminum tube you can find that sold in those hardware store or you can also use wood

3. Easy to assembly even without any instruction

4. fiber glass plate are nicely CNC cut

5. It light!, my DJI F330 is heavier than this frame :p

6. can take props size up to 12 inch!

7. all mount hole for motor pre-drilled but does not quite fit my DT750 motor

 

CONS:

1. no instruction manual (it cheap can’t complain much) but would be nice to have one.

2. the fiber glass may wear out if you fold and unfold the frame to frequent.

Overall it a good frame to have especially for those looking for budget frame and don’t want to make your own frame :), still planning what to do with this frame maybe I’ll put DT750 motors or get a new smaller motor for this for now it will be join my others stuff in the cabinet
