Hello I am getting back into RC planes and apparently I've missed a lot. I used to fly the big gas powered RC planes with 27 MHz transmitters and no autopilot features.
I want to build a flying wing fpv under 250 g. I would like it to have a long flight time. I need efficient motors but they have been hard to find. I'm hoping to do a 2s or 1s to save on weight. But I'm having trouble finding parts. So I guess my first question is can anyone point me in the direction of a 1-2 s electronic setup for a flying wing? Or store that would have what I'm looking for? 40 location where I can find more information on efficient motors? A lot of the motors I look at don't have any thrust data. Are there any brands that are known for having very efficient motors? I found a couple that have a 10g/w rating at 1-2 s but I'm sure there has to be more. And those motors are designed for quadcopters not planes. But they should be fine?
Hoping to have a receiver plus ESC
I found some efficient motors that run at 11500KV but haven't found any esc's that can push that speed.
I would like the ESC to use field orientated control but not all producers are publishing control scheme information. Might just make my own... It can't be that hard.
Is wing warping a good idea? I was going to reinforce the wings with a carbon fiber rod so I could just apply a torque to that and that should warp the wing. Would definitely help reduce drag does. anyone tried this approach before?
I would like to power it with lithium ion batteries that are flat and normally used in laptops. Should be able to tuck them into the wings pretty nicely. They should offer double the energy density of lipo. The only issue is maximum current draw with them be limited to roughly 5 amps. But from my calculations that should be pretty easy to achieve. I will say I'm not the best with Reynolds numbers and drag coefficients.
I also have the idea in my head that I'm going to 3D print the body of the plane. I have some pla plus which offers just enough rigidity and flexibility. And I have been able to print spars and ribs into the solid model. That was not really a question I'm just looking for opinions.
There's also the question of fpv which I have not started researching yet.
It also be really cool if it had a pix hawk for autonomous missions. but I haven't been able to find any ones that are lightweight enough. I guess I would also need a gps
Sorry if this is in the wrong spot. First post. I have a million more questions so
