I'm currently in the process of building an 8 foot wingspan flying wing to be used with ArduPilot, anybody have suggestions? DIY Drones seems to have no sections dedicated to flying wings.
Edit: That was pretty open-ended. I'm looking for info on what brushless motors have been used successfuly, and what kind of sensors I should get. (Pitot tubes, altimeters, IR sensors?). I'm also curious whether the purple APM2 still takes 4 weeks to ship (Would it be faster if I ordered the unsoldered version? I can solder.) , or if it is worth getting the old ArduPilot Mega. I've attached the rough plan, I'll put up the full plans in a couple days.
Are you building from scratch or are you using something like the X-8 Wing?
Curious as to why you want one that large? Seems like the RiteWing Zepher II is plenty big w/ a 56" wing span. http://www.ritewingrc.com/buy-cores/wing-cores/
He has already done all the R & D. Very stable platform.
I'm also building a variant of a "mothership" flying wing drone. This got put on hold for a few years while I remodeled my house, so I'm needing to get back to it. And all my parts are probably out of date, so not much help if you're sourcing parts now. I'm planning on building a center section for it via 3D printing, but I haven't started that process quite yet (need to build my chops on CAD). I got the original ardupilot for it, but now will punt that to another robot or drone and use the APM2 for my Dronewing.
What sort of response are you looking for? Are you looking for tips on designing the plane, or on usage of APM? Maybe the electronic paraphernalia required, or which construction method to use? My point is that yours is a very open ended question, and that you might get a faster response if you specified what you're looking for.
In the UK the Large Model Association would deal with this sort of size model. In the US, I don't know who deals with that, but most model clubs have huge models so someone would be able to point you in the right direction. Have you tried http://www.rcuniverse.com/?
two about 700watt motors, I think static thrust should equal total weight or little bit more,
low kv motors.
I have a 8 ft wingspan cub, with a OS .91 Engine. Is it ok to use the nitro powered engines or is it a bad Idea.
Cheers, it's covered in Oracover film, it's a bit scratched on the underside due to landing in brambles a few times, I am working out the best power system for this thing, its going to need something quite tasty to get it flying nicely...!
My advice for drilling the holes would be to use the wing tubes themselves as drills: heat them up considerably with a heat gun or other appliance, and once they are fully heated, push them through the material where you want them to go. Keep in mind, there are other methods which will provide for much better accuracy of placement. However, this will get the job done with relatively minimal effort.
there are build videos for these Hercules there very similar to your plane !
I'm already building one based on same idea as yours. My center section is built from CNC plywood, wings are MaxiSwift. I'm only few hours of work before maiden.From what I know, "empty" center section seem much more practical than solid foam for installation of electronics. When you cut too much, it's bad for rigidity.
It is 1.6m wingspan, powered by 6S 2.2Ah and 560kV outrunner.

Very similar design is already flying in austria.
I will post CAD files after maiden
