I'll add to this first post as the project progresses. Not sure yet if this will make it off the pc, a couple of stability/pitch/cg/thrustline issues might prevent me from actually building it. I'm finished with drawing all the parts and now I'm creating assembly instructions (like spacing) for myself.
The P1078C is a Flying Wing project from Heinkel that never made it off the drawing board. (how fitting)
wing loading at 2300g: 69g/dm^2 / 23oz/ft^2
Propulsion: 90mm Changesun 12 Blade EDF on 6s or 8s. (possibly 4s)
Weight: I'm aiming for 2300g but everything under 3000g would still be ok.
Materials: Balsa 2mm/1mm, Plywood 2mm, Depron 6mm/2mm and CF-Spars.
Dollystart and bellylanding.
FSA=5286mm^2, outlet=4757mm^2 (~90%FSA), Inlet=5093mm^2+1000mm^2 from the rounded inlet area.
I'm using a model I found on the internet as a starting base and modified it to fit the thrust tube etc.
currently I'm drawing up plans in sketchup. I'm trying to put the work into into the plans upfront so the assembly will be quick and painless.
Very large elevons to allow for a noseheavy CG. Similar projects encountered problems with elevator-control.
Two battery compartments under the cockpit and above the impeller to stay flexible CG-wise.
Assembly should happen without a rig. The two square carbon wingspars are supposed to provide as a leveling horizon for the construction of the wings. This has worked quite well before on another project
