Awesome Youbi XV-130 -- Full Review
I know there are already a couple threads on this one, but since my sample came from a different vendor, I think it should be enough cause for another thread, and even though it's never as popular as other threads :( I like posting my own threads :)
Anyways onward>>>>> The Youbi arrives in a nice looking, high quality box made of thick cardboard. It reminds me of an iphone box where it's difficult to remove because of the suction that's created when the box is closed. Inside, the contents are neatly arranged and the quad is safely encased in foam protecting it against the harsh journey.

Electronics are encased inside a plastic canopy and consists of a 4in1, 20amp Blheli-S, ESC setup -it also acts as the PDB with contact pads for a buzzer and LED's. Residing on top of the ESC's, is the F3 flight controller with an integrated 5.8ghz, 40 channel VTX. The youbi's frame is a 2mm thick carbon fiber plate ...that's pretty much it lol. Of course there is the canopy too, which acts as protection for the hardware tower inside. The Youbi is powered by 1306 motors @3600kv with a max thrust of 265 grams per motor -it's definitely a screamer!

Push the canopy forward slightly and a little wiggle and it comes right off. http://i1224.photobucket.com/albums/...IMG_6723-1.jpg Here you can see the F3 flight controller, which has an integrated VTX. I've already connected my receiver here, but with the canopy off you have access to the hardware tower, and the microUSB port! http://i1224.photobucket.com/albums/...IMG_6719-1.jpg bottom of the FC, here is the VTX module. There are also pads to solder on a buzzer or LEDS. Just below the FC/VTX is the 4in1 ESC board. These ESC's are 20amp blheli-S, so Dshot capable! Also on the bottom of this picture are contact pads that you can solder an XT60 pigtail to. http://i1224.photobucket.com/albums/...IMG_6727-1.jpg Bottom view of the ESC board with a view of the XT30 connector. You can easily keep this on, even if you choose to solder on an XT60 http://i1224.photobucket.com/albums/...IMG_6722-1.jpg Here is the Youbi's 600tvl camera. It has a 100 degree field of view, and is set in place at a 25 degree angle. Unfortunately the mount holding the camera does not allow for adjust ability.

Flight Testing
2S 700mah ??C So far I have tested the youbi using 2S 700mah and 3S 1300mah Lipos. Not the most preferable sizes by a long shot -for me anyways. I actually think 2S would be perfect for those making the switch over to brushless, or someone that has some experience flying quads. Once the motors spin up to the right speed, the quad does feel zippy, but there is slight delay from when you throttle up. Testing the 2S outdoors using FPV, the Youbi really felt underpowered. In order to keep the momentum up, I had to fly at 80-100% throttle the whole flight. As seen in the "FPV Flight test" video in post 1, this made it difficult for me to control the quad. 3S 1300mah 65C The 3S had a ton more power over the 2S, but due to it's size, handling characteristics was pretty bad -made it feel like a bus. I think this could be improved with a better tune, but the best thing to do is to use the correct size battery. Somewhere between a 600-800mah would be the best size for a 3-4S lipo. With the 3S I did notice some oscilation on higher throttle usage, another item that should be alleviated with a better tune. 4S 1000mah 70C https://static.rcgroups.net/forums/a...g?d=1480914291 This time a ton more power over 3S, I still have not messed with the tune, ever since I slightly raised the PIDS and rates when I first got the youbi. With the 4S I felt much more in control, flips and rolls were easier to achieve due to the increased power. It was also more stable, but I was still getting oscilations, as well as instances where the youbi would dive. I can't tell right now if this is due to a heavy 1000mah lipo, or if it simply needs a better tune. I will hopefully be able to find this out my next test flight with the youbi, or when I get some new smaller packs. Pros -Adjustable VTX Power (25mw - 200mw - 400mw) -Durable silicon wiring -Light weight and does NOT require registering with FAA (in USA) -2S-4S capable -Zippy even on a 2 cell LiPo -flown indoors its a quick one, but after flying it in a more open area, 2S just didnt cut it for me: I wanted more -Blheli-S ESC's are DSHOT capable -Comes loaded with betaflight 3.0.1 -tuning not required, but is recommended ... Cons -Dipole antenna -Camera angle NOT adjustable -Camera- not the best camera -Access to microUSB port- must remove canopy -No place for receiver antenna- you can either drill a hole in the canopy, or tuck it inside, I haven't found a good place yet ... Final Thoughts ... Modifications/DIY XT60 pigtail- The youbi uses an XT30 connector which is quite restrictive as much as it is uncommon. From what I have been reading in the other threads, It seems like most people actually had to purchase new batteries just for this quad. So... imo, it is a good idea to solder on a pigtail connected to an XT60 connector. There are actually contacts on the ESC/PDB board allowing you to simply solder the pigtail to - seen here: https://static.rcgroups.net/forums/a...g?d=1480542899https://static.rcgroups.net/forums/a...g?d=1480542901https://static.rcgroups.net/forums/a...g?d=1480542971https://static.rcgroups.net/forums/a...g?d=1480543558 The canopy fits snug, so if you plan on keeping the xt30 connector on there as I did -you will have to cut out a hole for the pigtail. I used an exacto knife to cut out roughly 6mm Betaflight Settings ... |
