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

Been testing the frame for a while now still can’t get APM2.6 to fly properly with the frame, need more flight time on it, my current setup as follow

– ATT-X4-16 650 Quad (Goodluckbuy)
– RCTimer 650kv motor with 12×4.5 carbon nylon props
– F30A simonk ESC
– Hobbyking Power Distributor board
– RCTIMER gorpo2 brushless gimbal combo
– 4200mAh 4S 40c Ty-MAX lipo

Pro:

– Big Size! can take up to 13″ props
– Double CF plate top/bottom for motor mount which X8 configuration posible
– Foldable! easy for transportation especially when you use big props!

Cons:

– Frame come with no build instruction
– landing gear are a joke so flimsy might as well get a sturdier one
– heavy frame 400g+
– Fiber glass rod, invest some money on CF rod 12mm for landing skid 16mm for arm

I used 12×12 aluminum for my Gimbal mounting as I have no way to mount my gimbal with the 12mm rod, everage flight time 5 min  probarly the tymax battery is going to die early, and I have not even put my FPV gear yet , will have to figure out most efficient setup and props combination with the motor
