Some of the components could be burried in the wing, so I would not be too worried about folding. I just think a flying wing like Xeno is not the most stable platform for FPV (same reason why the XB-49 was not a good platform for a bomber ).

I am, as wing loading and air speed go up, hence higher g-forces are generated in dives and turns.

Cheers,

See the FPV pods developed by various people for Slinger.
Modding Xeno for such pod would imply massive changes though, at least the two internal spars.
Still possible to disassemble it, but not foldable.
Also, especially for FPV, I would still consider the Mars Ares Eagle mod.
The presence of a tail would make it more stable and less CG sensitive.

The Xeno does not have ailerons, but elevons. Aileron controlled models usually need coordinated inputs of aileron and elevator to turn. A rudder controlled model like the EasyStar might be easier to set up.

I seem to remember one of the top FPV guys over on the Easystar thread fitted Easy Glider wings to his EZ* (an easy mod) ..... runs the kit on two 4,000 mAh lipos and is famous for a video he made flying out to an off-shore light house (10km out in the ocean) .......

Hi Renatoa, thanks for the info - can you post some links so I can see what you are referring to?

IMHO you could burry the autopilot and additional batteries in the wing root with a little careful though to some additional reinforcement with carbon fibre rods/strips but I would like to keep the ability to fold the wings (a great feature of the Xeno IMO) and just bolt on a small underbelly pod containing all the extra gear. Anyone with decent CAD skills out there that could do a mock-up and give me some ideas?

I have flown my Xeno pretty hard already - no problems. I would not expect an FPV model to be flown that way. Moving components into the wing reduces wing bending forces even more.

If the guy that is building this pod has good plastic processing skills, it can even replicate the Xeno belly hinge, and keep the folding feature.

you can make a decent fpv setup within 30gr, just go with that, i garantee you that wont fold anything.. you don't need to have 50 ezXX components 3 HD cameras and 3 spare 5000mah lipos onboard!


light camera, uncased ~10gr or less (cx161 is like 6gr uncased, the 555 isnt a lot more if you'd rather have 550 lines)
light tx ~6gr (airwave uncased, like the 2.4Ghz 500mW)
small OSD (whatever suits you, approx 15gr with GPS and zero additional crap)
small LC filter or driver (1 to 5gr DYI)
wiring (solder most stuff to avoid heavy plugs, use light wires) 1-2gr
DYI antenna: <1gr
shared 2200mah battery with the engine
total ~30 to 40gr ..

i use something like that on other planes, except its a 5.8Ghz 25mW airwave. you've some hand work to do as usual yes.. but so many times lighter!

of course if you go the "regular way" with extra lipo, cased 130gr cam, zillion osd-f16-ultra-whatever components it will weight 3-400gr which is too much.

But as long as you dont care about "real air speed and alt", "horizon", "current sensor", "auto pilot", "giro", "pan&tilt" and things like that, you'd getting nearly the same result, except 10 times lighter.
i suppose you could add some of the above options and/or make them lighter so that your total added weight doesnt go too high.

I will make my own engine holder so I drew the back of the plane in ACAD 09. There is so much new in 09 to 06 so it isn`t really well, but here is the picture with datas in mm Milimeter



I hope i could help

that is great looking! the paint! please do post flight times in dead air when you give her a go! do you think you may do any sal's with it? side are launches?

You probably meant "Side-Arm-Launch". Typical SAL models are much more efficient for this type of flying.
