Title: Skywalker X6
Post by: Miles on November 22, 2015, 08:02:01 PM
I've been looking around for a wing a bit smaller than my X8, but bigger than my 80mm Z84, so I picked up an X6 from the HK Cyber sale from the EU Warehouse for £31 :)

Should be here in the next few days, but for now, this is how I plan to fit it out:

OSD Pro + Guardian IMU + GPS + Airspeed
OpenLRS 100mw - HK had the TX units on sale for £2, given that they can be made into PPMsum output RX units, I'm repackaging one and fitting it to the wing
5.8gHz VTx with CP antennas
Hitec HS-82 MG with metal arms
Gopro Hero 3 + WDR700 Flight cam on pan & tilt - Thinking about ordering a video feed switcher
60A ESC OPTO
XYH-3548 1100KV motor
11x5 CF Prop
3300-5000mAh 4s Lipo
8A BEC for all 5V systems

In the long run, I want to fit a PixHawk, so after seeing Coyotes Twinstar, I'm going to try and fit a 1/4 wavelength 433mhz antenna in the vertical stabilizer on the central pod for a 3DR Telemetry module. Also looking at fitting either flaps, airbrakes or an under-fus. speedbrake, and a "Harrier" style landing gear.

Pictures to follow, though having a fight with HK so looks like they won't be here for a few weeks :/

gutted I missed the x6 at £31 though :(
Title: Re: Skywalker X6
Post by: Miles on November 22, 2015, 08:18:55 PM
I ordered some Fatshark 700TVL cams from them in the same order. At about midday today the status changed to backorder, as their system got clogged up with all the cyber sales orders.
They've now held the entire order, and although I can cancel the cams, its a total discount of £80....
Asked them to split the order and offered to pay extra postage, but they aren't a very flexible organisation.
I think I'm just gonna wait it out, hopefully it won't be too long until more cameras arrive....

Title: Re: Skywalker X6

Should be :)
Saw a good thread on RCGroups about them with Bignose's one on it, I like the idea of the ply plates in the base.

The only thing I'm not sold on are the RS232 connectors used to interface with the wings. I like the idea, but alot of people have pointed out that if wing wobbles or slides, I could lose the connection :/

Anyone had any experience with these?
Title: Re: Skywalker X6
Post by: Miles on November 22, 2015, 11:01:21 PM
These are said connectors. Might try and detach from the plastic mount and add bolts?

I'm not going to be using them in my X6.....Servo connectors for me, with keeper hooks... :D

I like the idea of a single connector, just not the idea of losing control in a spin that could be recovered from :)

Forget the d sub connectors, waste of time, if you can transport the wing in one piece then it's a no brainier, you'll get a locking screw to hold the wings on and mine ain't never come loose

I'd like to keep the wings detachable so I can carry it around in its box :) But good to know that the mount is secure, vs the terrible ply wood and screw on the X8...
Title: Re: Skywalker X6
Post by: Miles on November 30, 2015, 08:44:13 PM
So, the wing arrived today :)

Very happy with it, though there are a couple of little dings on the corners of the wings, nothing major. Also a little disappointed with the motor mount, so will be ideally 3D printing a replacement. My HS82 servos are a little shallow for the recesses on the wing, so I'm going to cut some depron inserts, bringing the outermost surface of the servo into line with the wing.

However looking inside the Fus, there are great options for mounting removable plates for components etc :) Also has some good grips for hand launching (Though the internal area behind is a little thin), a recess that looks like its designed for mounting a plate for a launching hook. There is a recess in the leading edge of wing, maybe for a Pitot or LED "Landing lights". The final recess is in the nose, for a gopro, though it doesnt seem to leave enough space for housing, but I've got some aluminium housings which I should be able to embed :)


Will be making a start on the wings tonight, pics to follow :)

Good luck, if you go on campilots web site you can download a dxf for the plates I had stef cut on his laser cnc machine, fit perfect, you could always print them
I found the motor mount to be fine mate, no worries
Title: Re: Skywalker X6
Post by: Miles on November 30, 2015, 10:04:53 PM
Tried to shine a torch through the frame, shows the thin area. Not sure how I will, but I intend to try and bulk it up a little bit.

Also, still not the sure about the mouldings in the front edge, but should be fairly easy to fit a pitot :) Not sure how exactly I want to mount the GoPro, angle seems very downward facing.

I have a copy, planning to making a few small changes :)

I want to be able to change the motor, and have it internal. Due to the length of the motor I have atm, I can't fit it without cutting into the foam, which is something I want to avoid :)

I'm going to modify /add to the plastic mount, so you can remove / change the motor later if you want to.....

Reasons:

1 This model has a tendency to come out nose heavy.
2. An external mounted motor will run cooler.
3. The plastic mount has a lot of gluing area.

The motor mount in mine looks fairly substantial to me, mine is black, made from a different material to all the other orange stuff. I can't see there being a problem... hope I'm not in for a nasty shock
Title: Re: Skywalker X6
Post by: BlueFlyer on December 01, 2015, 12:24:21 AM
Also, I will be using MPX connectors to bring everything from the wings into the fuselage.... I've just done this on my skywalker, so much easier and quicker now to put the wings on at the field with only 2 x plugs to connect, compared to the 4 servo connectors previously
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 12:25:02 AM
I don't have an issue with its strength :) It just doesn't meet the requirements I have for it.

Saying all that, this is all way better than my Gen 1 X8 :)
Title: Re: Skywalker X6
Post by: BlueFlyer on December 01, 2015, 12:37:38 AM
I also just noticed the recess in the leading edge and a wire/cable channel leading to/from it... my first thought was pitot tube, but I'll not be using one on this.

My setup will be:
Eagle Tree Vector
35mm 1200kv motor
80A ESC
10x6 Prop
5000mah 4S
1.3GHz video
EzUHF rx

I already have a long range/endurance platform so this will be a mid-close range speed demon.

wings will be perma-glued AND fibre taped over the seams to keep them on :)

Sounds good BF :) I'd like to of been able to bond it all, but also want to be able to take it apart and put it in the box and carry it on bike.

Also going to make a new spar - Not a fan of this extruded stuff, but I think I have some roll wrapped stuff that's the right diameter :)

Post by: iwan_canobi on December 01, 2015, 09:40:56 AM
Mine should arrive today, I'll be transplanting the bits from my old flyingwings falcon/Z3 style mashup as it's pretty beat up now!

I'm thinking this would be good for a pan setup, any of you guys doing similar?

Mine will have -

910kV Motor
10x5 prop
Have a 30A ESC just now but may need more. This setup only draws about 18A WOT with a 9x6 so may be ok.
4S 3000mah
Tornado OSD
Mobius / Runcam HD2 when it comes out

You guys going to laminate it at all? It's nice to have a few others building at the same time, good to bounce ideas off each other!
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 12:21:08 PM
Sounds good :) I have thought about laminating mine, but not planning to crash it.... May revisit it later :)

This morning I had a mess around with the Laser, and have cut out some little 6mm depron insert for the servo bays. They fit nice and snug, and I've superglued them into the servo well.

Also cut out a set of the plates designed by CamPilot out of 3mm mdf (Not ideal, but had some lying around). I want to see how well they fit, then will probably make a few small changes to better suit my needs.

Will post some photos up when I get back to the Lab :)

I'll also upload all the CAD for any changes I make to the campilot files if anyone wants them, and the CAD for the servo inserts (I have a lot of depron, if anybody wants a set, whack me a PM :) )

Here is what the insert looks like:
Title: Re: Skywalker X6

Attached is the solidworks file, and a DXF file for the servo inserts.
They are Zipped as the forum doesn't allow .dxf or .sldprt....
Title: Re: Skywalker X6
Post by: iwan_canobi on December 01, 2015, 02:19:09 PM
Yeah I was more thinking just to strengthen a bit and make the foam less susceptible to dirt and dings! Could you share a pdf version of the plates? I may give it a go just using some plywood and a stanley knife! :D
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 02:21:59 PM
Will do - Just making a few changes, as the rear plate seems to be a little narrow, falls between the supports in the rear section.

If any of you need nice 900kv motor I got it cheap to use with 9x6 prop. I was using this on my SW.Motor is from BEVRC for skywalker, really nice one.

Is there a manual online anywhere with details such as recommended CG and control throws etc?
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 03:37:35 PM
Campilot talks about both on his build log, tbh, I've not even looked for a manual yet.

Will upload the photos for where he reckons it should be.
Title: Re: Skywalker X6
Post by: Loopdreams on December 01, 2015, 03:43:07 PM
Yeah, I just like to get info like that from designers because for some reason a lot of people seem to set up their wings nose heavy with loads of reflex and massive control throws.
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 03:45:48 PM
Yeah - Though I have a few ideas about battery configs that may help with CoG issues :)
I always do first flight with throws on a 3 pos switch, so I can reduce / increase in flight :)
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 07:15:36 PM
Spent most of today in the Lab, and have sorted out the servo mounts, and had a look at the battery bays and battery configuration.

First few photos are without the insert, last 3 are with. The insert is made from 6mm depron thick, and is just glued into the bottom and sides.

Outermost face of the servo now sits about a mm below the face of the wing. I've got some alloy servo arms coming from the HK EU warehouse, hoping they'll arrive soon so I can finish that part of the wings.
Title: Re: Skywalker X6
Post by: Miles on December 01, 2015, 11:38:54 PM
Other thing I worked on today was part of the battery mount. I've looked and modified the plates by Campilot, and layered some depron underneath to bring it flush with the base of the fuselage. It (will....) attach using 2 ply plates. One will be glued into the base of the depron, and the second glued to the out side of the aircraft in the little recess on the bottom of the nose. This is where I'm going to be mounting the launch hook for bungees.

I started by cutting out the campilot plates. On the whole, their fairly good. My only real issue is with the plate that was designed for the rear electronics bay is a bit too narrow.

I've heard alot of reviews saying it's very easy to get the CoG too far back. I still want to get a fair amount of batteries in this, so I want to try and get one under what will be the electronics tray.

Just for reference, the 3 6mm depron layers bring the 3mm mdf plate up nicely :)

I'll write up a bit a more about the battery mount later, and I'll upload the CAD soon.

I honestly think you won't be able to get CG correct if you have that battery in the back bay.
Title: Re: Skywalker X6
Post by: Miles on December 02, 2015, 12:06:05 AM
I'll have a mess around - will see how it works out. It seems the issue is that it goes too far forward. With the all the bits wedged in the front, looks like its worth a shot :)
Title: Re: Skywalker X6
Post by: bignose13 on December 02, 2015, 01:07:58 AM
When I tried to get a 5000 mah 4 cell turnigy in the battery bay, I had to have the battery all the way back in the bay AND another 3000 mah 3 cell in the rear compartment just to get it to balance
Honestly you ain't getting anything other than a 4000 4 cell turnigy max in the battery bay, unless major surgery to the middle foam partition which I don't recommend
Good luck if you do though
Cheers

Ta :)

Attached are the CAD files for the 3 6mm depron and 3mm plywood/mdf plates. They are a pretty good fit, but I think there's a few more changes to make to them yet. Credit to Campilot for providing the initial dimensions.

Next up will be doing something similar for the electronics plates in the rear bay, and the shelf of the front bay. Again, I'm going to use depron to increase the height, with cutouts in the depron layer to help conceal cables without needing to cut into the airframe.

Title: Re: Skywalker X6
Post by: BlueFlyer on December 03, 2015, 01:24:52 AM
are you using a ply shelf at the back?

I can see some ridges on either side of the inside of the fuselage in the rear compartment, I'm assuming they're for a shelf of some description but I don't think the X6 comes with one.

Yes I am, and it doesn't. Campilot has made one, but it seems a bit narrow, and on mine, it only gives a mm of contact on each side.

Because I want to get a lipo in the back, his plate is too long to allow that.

Should.have time to design a replacement in the next few days :)

Looking at campilot's build video, it's clear that I have a different version of this aircraft.

His has the recesses for the servos on the underside of the wings and an orange motor mount

My wings have the holes for the servos on top of the wings, and a black motor mount
Title: Re: Skywalker X6
Post by: Miles on December 03, 2015, 10:34:47 PM
I didn't watch his video that carefully - I presumed he covered over the servo holes.

I think I have the same version as you.

This may in part explain why the rear plate as designed by campilot is too narrow.
Title: Re: Skywalker X6
Post by: Miles on December 03, 2015, 10:40:46 PM
Attached are a revised version of my battery bay mount. I've redone the depron layers to give a larger gluing area between them, removed the rearmost battery strap hole (Was inaccessible when in the aircraft), and increased the size of the cutout in the lower depron layer, allowing for a larger plate to be glued in to secure through the airframe to a launch hook.

I've also uploaded the files in STL and IGES :)

I haven't cut these ones yet, but the external dimensions haven't changed, and the last one fitted great, so they should be fine.

Have done a quick design of a electronics bay for the rear of the X6. This one's designed to fit an ET Vector.

Just watched the Team Legit build video... that too has the servo holes on the underside of the wings...

I thought I might have been going a bit mental, so I just popped down to the garage to check... lo and behold I confirmed my thoughts... I have different wings compared to campilot and team legit. I doubt it will cause any issues though

On the up side... my fuselage halves are now glued together :)

I guess HK are selling a newer version? There's at least 2 versions of the X8 going around.

The Team Legit and Campilot kits also come with the ply motor mount.... mine (and I suspect this whole batch of £32 X6s) does not have this ply mount.

I think this is a good thing though... from what people are saying about it being nose heavy, having the motor further back should help with that

Oh, and Miles.... have you figured out which way to angle the motor mount yet? notice it's not flat, so the motor will be either pointing down or up

I think I'll be pointing mine up, just from prior experience with flying wing aircraft

I'm probably going to angle it up, though I am still planning to make my own mount. I'm not sure what angle that'll be at though.

planning any paint job?

I tend to paint my wingtips black... just because it's the only colour paint I've got around lol

other than that... because of how cheap this kit was, I'm not planning any aesthetically pleasing features.... there'll be plenty of reinforcing tape in key areas... may paint the tops of the hatches too... just for gits and shiggles

Nothing fancy - Front canopy cover in black, and maybe the winglets too. I am going to try and lasercut some vinyl stickers though :)

I recut my depron inserts today, can now access both of the battery straps :) Will also be cutting the plywood insert for the base to secure the bungee hook too.

If you want to 3D print, I can merge the multiple layers if that'd help.

go for it il see how it comes out

I Lasercut the first version of the motor mount the other day, it consists of 4 parts; 2 firewalls bolted together and aligned using the ply spacer, and a raised motor mounting plate designed to be bolted onto by the X mount.

I've machined off the outer face on the plastic mount, which will sit around this assembly. The rear plate fits inside it :)

The ply spacer was a little too short, as it turns out that the internal face on the back isn't flat....
I also made the hole to pass the connectors through a little small, and found that I can't use the larger plate with X plate as it's too big for the inner diameter of the plastic housing.

I've just designed a new version, will cut it this afternoon :)

I've modified my TS800 5.8GHZ VTX, removing its cooling fan. Because of how I'm mounting it, the heatsink will be nicely in the airflow. I'm going to be fitting a temperature probe, as I don't want it to overheat when I'm on the ground. This will go into the OSD, with warnings based on values deemed acceptable from testing with the fan reconnected.

I've had to cut away at the foam a little - The bays are more designed for the long rectangular Lawmate type VTX units, whereas this has a central antenna output. This afternoon I'll cut some inserts to hold it in place :)

Done quite alot of work over the last few days. I've glued together the fuselage, and made cuts in the rear bay, and cut a space for the gopro.

I decided that the best place for the ESC to get some good airflow was to mount it on the outside, and have mounted it in the recess (For an undercarriage?).

Cables come out nicely in the area by the wing spar, and the motor cables toward the tail.

I've cut out the mount for the Gopro. The alloy housing has a detachable backing, but will be fixed to a tilt servo so I can have it pointing forwards or downwards.

(http://s3.postimg.org/3y2p2mxov/WP_20151210_22_42_28_Pro.jpg) (http://postimg.org/image/3y2p2mxov/) (http://s3.postimg.org/61d4aaxhr/WP_20151210_23_17_32_Pro.jpg) (http://postimg.org/image/61d4aaxhr/)

I'm also going to be mounting a flight cam on the canopy. I've ordered a little video switcher, but I need to make sure that it all plays nice with the OSD pro.

looking good Miles, that alloy case looks really nice.

I get really lazy when it comes to taking pics during my builds, I'll end up putting up a thread once mine's complete :)

Cheers :) They were £3 in the HK sale, I'm going to lasercut a "faceplate" for it when I get back to Uni.

Last post of today.

I've installed the high strength mounting for the battery bay. I will be replacing the zip tie with some bolts ASAP though, as the zip tie covers the hole that's there to allow me to screw in a hook.
(http://s18.postimg.org/ifxjrr0l1/WP_20151211_00_18_50_Pro.jpg) (http://postimg.org/image/ifxjrr0l1/) (http://s18.postimg.org/o1fdi2bw5/WP_20151211_00_18_56_Pro.jpg) (http://postimg.org/image/o1fdi2bw5/)

I've finalised the design I'm using for the rear mount, and I've made a slight cutaway on the edges. This allows me to get the plate in and remove it now that the fuselage is glued together, and makes it easier to mount another plate for a battery in the back :) There's also space in each of the slots on the sides for 7 Servo connectors. There should've been 8, but I couldn't find my calipers so measured with a ruler, which wasn't accurate enough....

I've also modified my OpenLRS RX into a "Low profile" setup, have replaced the pins with 90 degree ones, and added a servo connector to the telemetry pins.

I just need the rear shelf... a sheet of G10 is going to cost me £10 from ebay, but it's going to look like a toddler's cut it out... ideally i'd need someone with a cnc or laser cutter to cut it for me, but I've got a few other things I'll want cutting too, so I'll be trying to draw something in either sketchup or inkscape... I don't have fancy software :(

After a slight delay in the project, the Skywalker X6 flew yesterday!

https://vimeo.com/168617020

It's had a few changes to the spec:

Frsky X8R RX (Temp, still using OpenLRS)
200mW 5.8GHz VTx (Temp, have a ImmersionRC 2.4GHz to fit)
10x6e APC Prop
5200mAh 4 s Multistar (Will be looking into fitting a second, but need to fit the GoPro in the nose to resolve weight issues.)
85A ESC.

This thing is nuts, the vertical performance is unreal. It did have my OSD pro equipment fitted (No FPV, but it did log the flight). There was a GPS glitch, the actual true top speed was 87.2 MpH - Still pretty fast, and with FPV, I know I can get it faster. The Multistar pack isn't enough for sustained WoT - I could hear the low voltage alarm in the glide after while the voltage crept back up.
