UPDATE for Alien 680 / 700 owners:The Alien wobbles a lot with the default Naza gain settings. To get vibe-free video on my 2.3kg big Alien quad which spins 15" props with 380kv sunnyskies on 6S, I had to use the below gain settings:Basic gain: 165 row 165 pitch 155 yaw 165 vertical Alti gain: 140 140 Do not be afraid to crank up the default basic gains to 150, then increase it by +5 at a time until it kills the wobble.
Thanks for watching, this is an interesting question. I would go with probably a custom built folding frame which is a hybrid of carbon plates (CNC cut) with some unbreakable 3D-printed parts (nylon filament). Then again, you could probably buy a cheapo drone from Banggood or GearBest which mimics the appearance of the Mavic. Dig out all the trash electronics inside and put in your own PixHawk /Naze32, mini OSD, mini GPS, etc. Will be a fun project!
Today in 2020 which machine would you recommend, I am a rc pilot been flying planes for many years... I wish to build a machine purely for making videos & long duration quad machine..
Among the 3 in the video , only the large folding Alien with 15” props could fly for 30mins, the other custom build drones could only fly for around 12 to 15mins. Hence you would need to choose that or an equivalent frame that spins 15” props. Also consider getting a DJI Mavic as it costs cheaper than DIY and could fly 25mins and produce descent quality videos for production
I got the h680 i want to know why fly for few minutes my ccw motors always got too hot when tourch as compared to my cw motors. Motor mounting are balanced.
I have that on one of the 3 drones. If you have calibrated all your ESCs end points and balanced your motor mountings, the only suspect are the blades of the prop. I noticed the cutting angle of one ccw prop is a tad lesser and this makes the ccw motor work harder. The other issue about my ccw prop is the uneven carbon fiber surface, I guess this has something to do with the manufacturing mold for the ccw. In the end, I sand the props, rebalance them and spray clear lacquer on them. This helps a bit only since nothing could be done about the pitch problem.
The alien450 is a 99usd carbon frame (without landing skids) from aliexpress.com The quality is really good, when compared to the hobby king alien 560. I used the landing skids from the Turnigy 345 quad frame
Sure. Alien 680 (biggest alien) is at www.goodluckbuy.com/h4-f660-fpv-carbon-fiber-folding-alien-quadcopter-frame-kit-w-folding-landing-gear.html and Alien 450 (smallest alien) is at www.goodluckbuy.com/h4-450mm-carbon-fiber-folding-fpv-alien-quadcopter-aircraft-frame-kit.html and the LS-480/ XJ470 (white one) from AliExpress/ Hobbyking is already discontinued.
True, but this video was 2 years old. Sadly, the Mavic turned this hobby into "Hey genius! I can have it all by parting with my salary!" kind of state. On a positive note, it makes the hobby more popular and easier than before.
Terence Chan well actually i dont use a mavic i biuld mu own drone using popsicles sticks it can fly morethan an hour and has a obstacle avoidance my goal is to have a drone that what a dji drone can perform in a much lower price
It is a Quanum XJ 470 (hobbyking) and a Lisam LS-470 (aliexpress). Both are identical but they are discontinued. The replacement model is this: www.aliexpress.com/item/32770447311.html

Nice summary. I was just thinking about building up that butterfly frame. Keep in mind that you can turn your Naza into Naza v2 now...
great vid, yours is the only one i could find on the gf 450. nice build with all your quadcopters.
+Rain L Thanks!the motors on the gf 450 are the gold Turnigy 1450kv aerodrive from Hobbyking. Due to the high kv, 8" props are used.
How can we be sure that GPS signal is connected properly during flight in pixhawk with out using telemetry?
You could set the arming check to include GPS, this means the motors will never arm until a gps satellite lock is established.
Nice setups :)
Thanks for sharing and happy friday
Thanks, hope u have a pleasant weekend too
Thanks for sharing this vid.
If you were to do it again today, a couple years after you posted this vid. Any thoughts on what you would go with?

Great vid man, I gotta clear my bench off and review my quad designs and failures. LOL!
Hey mate, it would be great to see all your setups. :)

@@terence79chan Hi, at present I do not have a budget for the Mavic, but I already have a radio, action camera

do you think a pixhawk would fit? what are the dimensions of the area for the FC?
The pixhawk will only fit well into the Alien 700.
what would be the best prop size for 650 sized frame with 920kv motors and 3s?
I would go for 12”
hi! what is the model/brand of the first foldable drone?
It's the quanum 480 on hobbyking. it is also called Alien 470 in aliexpress and butterfly 470 on other china sites
What type and manufacturer is the second frame, please?
The alien450 is a 99usd carbon frame (without landing skids) from aliexpress.com
The quality is really good, when compared to the hobby king alien 560. I used the landing skids from the Turnigy 345 quad frame
Hi. any link for the frames ?
Thank you!

sir ublox neo-6m GPS how to configur FOR CC3D step by step
soundtrack is?
Hey Huynh, I live in Singapore. Sound track is Korean instrumental piece.
Can you maybe make a alien 560 mm/ 680 mm ???, that could be nice !!! :-)
I like black quadcopter , im a kid
country?
singapore
Surely you could tell byTerrance's accent.....😁
Zero marks for camera work, not really useful showing us something that's out of the shot lol
nice but too heavy frames 360kv on 6s must have a flight time close or more than an hour not below 30 mins i rather buy a mavic same flight time
