Hi Alberto,the GPS port on the f/c has a sda and scl pins so should be o/k

4s 3000 mah lion will fit
May I ask: will the Flight Controller / BEC provide enough current on the DJI plug for an O3 air unit (9v 2a or better)?
JumperTechnology Store Vs UUUDrone Store
I purchased two of these aircraft. I ordered the one from UUUDrone on November 9. I also ordered one from JumperTechnology on November 10.
After shipping, they both cost about $314. (JumperTech’s total was sixty cents less than UUUDrone’s total.)
The JumperTech shipment arrived Nov. 23. The UUUDrone shipment arrived today (Nov. 28). The JumperTech package had an outer cardboard shipping box. The UUUDrone package had a layer of bubble wrap between the packaging paper and the foam storage box. Neither package appeared to be damaged during shipping.
The flight controller detached from the aircraft during the shipment from UUUDrone. My guess is the Idaho cold was too much for the gummy adhesive used. Here’s a photo showing the cleanly detached flight controller.
Without knowing how the flight controller was attached, I made a mess of some of the foam in the first aircraft’s flight controller.
Yes, I bought two. This allows me to feel more adventurous in testing/modifying one.

I have two O3 on order. Once I receive one, I’ll test it out with this aircraft.
I’m almost positive the 9V BEC is on the power distribution board. If the included BEC can’t provide enough current for the O3, it shouldn’t be too hard to add a more powerful version.
I’m seriously considering removing the power management board from one of my aircraft. The way the wires connect to the board severely limits the battery size which will fit the battery bay.
I’ll post separate comment on some battery ideas.

As I mentioned earlier, I didn’t have any 4S packs the right size to fit in the battery bay.
I decided I wanted try a variety of batteries. (I also purchased a few servos.)
I’m not sure all the packs are suitable for the Xiake. I’m not sure if all the LiIon packs can safely provide enough current.
I don’t know what sort of testing strategy I’ll use but I’m open to suggestions. Also let me know if there are certain packs I should test first.
FWIW, I have other aircraft which can use these packs. The packs will likely be used in more than just this new aircraft. I had been using a pair of 2S packs (in series) in some aircraft. It will be convenient to have proper 4S packs.
Edit: Apparently I can’t add another reply until someone else comments. Well here’s a post which I intended to add. Personally I think it belongs in a separate reply but I’m sure (at least hope) there’s a good reason for the “three sequential post limit.”
Wire Colors on ELRS Receiver
As I try to figure out the electronics on this aircraft I noticed the wires on the ELRS receiver didn’t match conventional color use.
It appears Jumper just used whichever colors were convenient (for them not us). This isn’t the first time I’ve seen red wire used on the ground connection but it’s still disappointing.
Here’s the pinout from the Jumper Aion section of the ELRS Receiver Wiring page.
Here are a couple photos of the receiver included with my aircraft.
Here’s the top(?) of the PCB:
Here’s the other side of the PCB:
As long as you use the provided flight controller and the provided wiring harness, you don’t have to worry about the wire colors.
I’m personally going to add some sort of label to warn me about the wire colors in case I swap receivers in the future.
This is another reminder not to assume the red wire is power and the black wire is ground. Double check the pinouts. It’s irritating that Jumper didn’t make the effort to use normal wire colors.

Daune thank you for this,it will help many,I am very very serious about getting a Xiake 800,as I have recently built a Heewing T1 VTOL and love it,I am kinda use to ardupilot,but what I love is autonomous flights they tick all the boxes for me,and I feel the Xiake 800 has a lot to offer as may take bigger batteries so will be watching very closely

If you’re not in a hurry, it would probably be a good idea to wait until Banggood (or similar) carries it in a local warehouse. As it is now, you’ll likely pay as much for shipping as you do the aircraft.
Of course there are no guarantees in this crazy world do it’s possible the deals available now are the best they will be. Personally, I think the aircraft will be available with more reasonably priced shipping in the future.

I’m currently designing a 3d printed canopy for it & the DJI O3 air unit Jumper Xiake 800 Canape by maro0016 - Thingiverse

Very cool!
Is there a reason you want the camera on top of the aircraft? It might take a bit of modification, but I’d think the O3 should be able to fit inside. Having the hot O3 inside the aircraft will likely require additional ventilation to allow for proper cooling.
Do you have an O3 yet? I’m still waiting on mine.
Hopefully you will share some photos of your progress. I’d really like to see what you come up with.
Thanks for sharing the link to your design.

I have my O3 already. I designed it so that the air unit is sitting on top, the antenna can be mounted and the camera is placed inside. That provides probably the best cooling. I might also add a mount for a additional BEC (@ 9V are 2A required)

Did you guys get in touch with MiniHawk VTOL | Hackaday.io for some kind of credit for the commercialization of their work??

Hi! Here is the canopy file.
Yes, I recently tried to contact him on youtube comments and leave my email, but my comment keeps disappearing. Could anyone please share his email address? Thank you!

Here is the link of the project page, which i think you know, inside you can find Steve Carlson and send a private message to him. I also contacted him and sent him a link to this page.

wow you guys did copy his product. Its very unfortunate that you have not mentioned him originally when you released this.

It has not the right size, they made it wider. But the length matches …
I understand it from a tactical standpoint - jumper wanted to offer the first cheap rtf VTOL. Now it’s the right thing to properly support the open source project…

I really hope that Stephen gets rewarded,but more important that he continues his great work as he is a very talented person,regarding Jumper they saw an opportunity and developed it,going by the post on you tube 5hrs ago they seem pretty serious about this,I hope so as the Xiake 800 has so much potential to get people into the hobby and into ardupilot.I intend ordering one in next 10 days or so as I see hugh potential for it and more important a lot of fun to be had

There are nine data connections between the flight controller’s PWM OUT port and the power distribution board.
I checked continuity to see where these connections lead.
Channels
#1 Leads to two pads on the back of the PCB labeled “LED.”
#2 The tail ESC (on the bottom of the PCB). For some reason this is labeled “S1.”
#3 Starboard ESC
#4 Starboard aileron servo.
#5 Starboard tilt servo.
#6 Solder pad on the back of the PCB labeled “S6.”
#7 Port aileron servo.
#8 Port tilt servo.
#9 Port ESC.
Here’s a photo of the top of the power distribution board with some of these connections labeled.
Here’s the bottom of the PCB.
It seems odd to me the silkscreen “S6” corresponds with position 6 on the connector yet “S1” corresponds with the position 2.
Another oddity is how the order of the wing channels are not consistent. The starboard wing channels are ESC, aileron, then tilt. The port channels are aileron, tilt and ESC.
None of this information is needed to use the aircraft but I thought I’d share this in case anyone else was interested in which channel did what. These are channel numbers according to the pinout on the flight controller PWM OUT connector (earlier post with pinouts). I don’t know how these channels correspond with the pins on the microcontroller.
