FlyingWings Genesis

So...  I've been looking for a tough flying wing that would be nimble and shoot the gaps while being able to survive the odd brush with a tree/hedge. 

There aren't many options available in the uk other than a Yeti or Zagi.  Money no object I'd get a Ritewing HC wing but its just too costly to import to the UK.

FlyingWings have the Falcon and Venturi Evo for FPV but I think of these more as cruisers.  For me the centre section is a weak point so I thought I'd try the Genesis instead.  Yes there is the Shadow but again I think this has a centre section so it limits how you can strengthen the middle section of the wing.

I added extra carbon top and bottom on each side going all the way out to the tips. I would have done the same top and bottom across the middle but this was a little difficult to plan out with the ply motor mount as well.  I was also not sure where I wanted to put the ESC so wanted to leave an area in the middle where I could hopefully embed this once final motor/camera config was decided on.  Other than that I added a strip of carbon along the top in front of the motor mount and a piece either side of the battery bay to try and avoid that being ripped off in a crash.

I've still not decided on the final motor to use.  A Sunnysky 2216 1250kv works quite well but top speed could be better.  I'm currently trying a DYS 3530 1700kv. I need to get a 6" prop to try though as on 4s it gets hot even if I stay below 50% throttle.

Lastly I added a little mount on the front for my fpv and hd camera. (Hacked from an unused Mini Talon Pod).  This added a little more weight than I would have liked so really I need a bigger motor on the back to balance it out  ;D

The wing has proved tough so far and very acrobatic youtu.be/fs7Ji_n6JrE

I wanted to test the durability so crashed in to a hedge on purpose (obviously)  youtu.be/4eIsx0HbdWs

That really does handle well, can turn on a tuppence ! :)
Education and schoolin is good, but FPV is gooder :)

I think building it light helps.  Only running a 2200 4s battery so flight times aren't incredibly long but I wasn't intending this to be an endurance ship

  Unlike some of their other designs, it doesnt suffer from nodding dog syndrome either...Plus its cheap because you have to cut apertures in to fit your bits in..
  I rather like it because its also big enough to be a bit of a cruiser with the right motor / prop combo...is t it also cut from EPO Sir Dave..?

The wing is made out of EPP so it should be pretty durable.  So far I've crashed straight into a hedge and clipped the top of a tree.  The true test will be if I hit something more solid...

I did wonder about putting inav just to have rth.  I would want to embed it though which might prove difficult. I thought it might be better to solder servo cables direct to the board rather than use the pins.  This would make it a much thinner form factor to bury in the wing.  I'd only really want it for rth and the osd, I've not found the auto-level modes to work that well.

Hi m8,
             Or, you could use some 90 degree header pinouts?...If you are going to bury it, then I would suggest the V2 F4 version as the V1 I have gets a bit hot...even with its heat sink.
   Yes, you may have seen I just test flew my Falcon with iNAV....What I did notice before I flew it was something a bit peculiar.
If you switch it into Horizon without the motor engaged, the self level function seem more active than if you start the motor running, even if it's just slowly, which is rather weird I thought..?

  It would be good to hear your analysis of this to see if mine is reacting "normally" as it were..? I know you guys have tested iNAV to death of late....Tell me what you think please..?

  Im using the Z84 PIDS preset on my Falcon, which may be a little tame for a bigger, smoother wings like mine and your Genesis?
Not that Im an expert in PIDs by the way..lol

Be interested to hear what your findings are....:)

I'm afraid its Matt that's been doing all the testing. So far I only have it in a Skywalker Sirius. The Sirius flies so slow it's not really the best test bed for it. I haven't touched the pids, just went with the default plane profile.  That's certainly strange that the motor affects its responsiveness.  I wanted to use the Sirius to try some thermal fpv'ing but find it drops the nose loads when I come off the throttle so that doesnt really work either.

I'll probably leave it out of the Genesis as all I really want from this wing is something fast(ish) and maneuverable to chase around the trees.  Want to see if I can build more loops or rolls into a flight but so they seem more in the flow of the flight rather than just a random roll

  Ok, I suppose the most obvious candidate would be the Mini Talon to see what the F4 and iNAV can really do...I take your point though, my Falcon is pretty docile so in Horizon Mode its not having to work very hard at all....I need to fly it some more to get a feel for it...I just dont understand enough about PIDs yet to have confidence in playing with them...:)
  I need to research that now...
Ask Matt if he has the same happening with his next time you go fly...its a simple test.

A set of iNAV presets would be brilliant for a Mini Talon dont you think...?

So I did manage to put the motor back in the Sirius to test the stabiliser.. I couldn't see it moving any more or less with the motor on. What did happen which was strange was with the motor on it would immediately try and bank the plane?!  Seems very weird, I'll have to double check my mode switch I think to make sure it was just in auto level.

While my wing build so far seems to be pretty solid having survived a crash in to a hedge, a tree and swiping a bale today, my camera pod is not doing so well.  Any ideas or suggestions on a tougher one or how I can repair this one?  I think I may have used E6000 to glue it in so not sure how easily I'll remove it!

I've just ordered one of these, been toying with a few different options but this looks like it flies great and is UK made which is a plus. I'll be going with a 1250kv NTM V2 I have with an 8x6 prop probably. I've got 2200 4S but loads of 3000's as well, do you think they would fit ok?

I'll probably put iNav in it as well, will need to have a look at mounting. I like the look of Matt's 3D printed nose so will probably stick one of them on in a semi flex filament which makes it near indestructible.

I'm sure the wing could take it but it may not fly as great.  My AUW including HD cam is 940g.  If you look at some of my videos at that weight it is acrobatic and glides really well - last landing I glided straight in to the Tree of Doom  :)  A friend added Vinyl and a heavy camera nose to his and was weighing 1.2kg.  The endless glide was gone and battery consumption increased significantly.

I've got the same nose on mine now, the adapted Talon nose didn't last long.  I used some of the foam from the battery bay to fill the gaps, feels strong but time will tell..

For me this wing is suited for closer range fpv dodging trees and obstacles.  I don't want it for a long range cruiser.  If I did, the Falcon would be a better option.  Matt has proved that iNav will fit and done a neat build, (although the hatch hides a birds nest of wires  :) ).
