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.
you need to go look at the build log for trappy on his new flying wing.
here is the kink. really nice write up and lots of info.
I have build a couple of 8 foot wings. Maby my experience can help.
I do not have any build logs. I just threw the wing together over a weekend.
I would be more than happy to answer any questions about the building process.
here is flying video of before AMP install(these videos were taken durring initial testing). It took me about 3 flights to get the PID's tweeked, Other than minor pid tweeking, AMP is handling the larger airframe GREAT!!!
Motor is eflight 160. Or a exceed monstorpower 160..
ESC Castle 120 HV.
Castle ubec HV 25 amp.
Servos s9156 futaba.
10000 mah 10-12s. or 5000 mah 10-12s
This set up provides PLENTY of power. and gives me a solid 30 mins of flight.
I've had a fair bit of experience with flying wings, biggest was 2.6m (100in) span, here's some pics, have some video of it too somewhere:
Later cut it apart & converted it to zagi-style swept wing with 2 vertical stabs on the wing tips and retracts. It flew on ridiculously little power, I think it was about 400W with a 3S LiPo, motor was a Dualsky PR40 with a 13x6.5 prop and it flew easily on 50% throttle. Can't remember the weight but think it was about 3.5kg (7.7lbs).
Normally planes need about 100W/kg (50W/lb) to fly, just watch that CG (I seem to recall the CG at +/-17% or less).
This was before I got into autopilots (although I did fly an APM1 equipped wing this morning but it's not nearly as big)
