GoodLuckBuy ATT-X4-16 650 Quad

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


– 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!


– 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

FX-61 Hobbyking Phantom FPV

Last year bought this plane for my fpv’ng but due to it large size it hard to bring this beast around, plane will be given away for free to anyone in malaysia if you are willing to pickup it up from me :)

Hobbyking does not seem to re-stock the plane anymore most probably it has been replaced by FX-71 buffalo or Go Discovery wing

My current setup of the wing are

– NTM 3536 1400KV 600Watt motor with 60A ESC

– 10×6 aeronaut carbon cam

– 4200mAh for short range and 10,000mAh battery 3S

– MG929 hobbyking 12g servo

– PV0420 640tvl with 200mw bevrc 1.3ghz video transmitter

– BEVRC RX with 5 turn Helical (10km record so far with 200mw)

– Dominator Goggle

– Storm OSD with RTH

Kits will include NOTHING only bare kits no servo or anything

some picture of it current condition


not pretty but still flyable :D, here was previously assemble with OSD

Hobbyking X550 Completed

I posted a short review on the X550, today I actually finished and with my AQ50D installed on it I maiden the quad!, I’m using HBK 800kv motors and SS 18A ESC (gonna flash it later with SimonK firmware)

My current setup for the quad:

– AQ50D

– Super Simple ESC 18A

– 2213N 800Kv Brushless Motor

– 10×4.5 propeller

– 2200mAh 25C

– 5.8ghz FPV VTX with clover leaf antenna (not installed yet)

– HBK E-OSD with CL-OSD Firmware

On average hover and some forward flight only getting max 6 minutes with the 2200mAh battery, maybe will upgrade it to 5000mAh or parallel 2 of those 2200mAh battery as after I’m use to the frame I will install my FPV equipment to the frame it probably gonna add more weight to it and even shorten my flight time.

Flight video will follow later :), I have high hope with this quad :p

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


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


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



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
