Hello all,I'm new to aerial photography and I'm trying to develop a solution similar to some commercially available products wherein the data is sent to a cloud for post processing. I'd like to use a raspberry pi to send all the pictures to the…

Hello all,I'm trying to design a delivery drone with a maximum payload of 2 kg and a range of around 13km. I want to ask if these constraints are feasible ? If yes, can you link me to some of the designs that have already achieved this or somewhere…

"Hey Philippe,
I think I used the incorrect term for the kind of controller. Yes, that's what I plan to do. I'll be using this dynamic model while designing my autopilot which shall take care of all the three modes i.e. hover,transition and cruise.…"

"@Philippe Hey thanks for the reply. No, I haven't seen that I'll check it out. I haven't designed the controller yet, but I'm planning to find the trim states for cruise flight and then as I transition from hover to cruise I'll slowly change my…"

Hello all ! It's been a while since I last posted, it's mostly because I've been busy brushing up on Aircraft controls and dynamics so that I can create an autopilot for the VTOL design. We re-iterated our previous design which was a flying wing to…

I came across this design on kickstarter. Any idea why the motors are tilted at such peculiar angles ? Is it supposed to improve dynamic stability or something ?

"@Richard Burd Thank you for the elaborate reply. That was really helpful. That's true, these softwares just churn up loads of data without giving the designed a feel of how the plane is going to fly and behave. I'll start working on the drawings as…"

"@Gary True that but I still feel VTOL are the future. I took this up because I wanted to work on something challenging. Sure I'll trying adding a tip underneath and post the results soon.

@Hyperguy It's barely anything. The Cd value changes by…"

"@David Torres Thank you for your reply. The current CG position is what it would have been, had it just been a flying wing and I plan to place the motors,payload/electronics in such a way that it comes to the required cg position. As for the change…"

Karan Chawla commented on Karan Chawla's blog post Flying Wing for Search and Rescue
"Okay so correct me if I'm wrong, stability is entirely dependent on CG location and only performance is dependent on the airfoils used.
So for Stephen his elevons would be slightly deflected upwards(say 1/8th inch) in level flight, is this what he…"

"@Stephen That's true we'll never get the exact profile. I have read about aerodynamic twist. Thanks for the link. Are you getting a better performance by using conventional airfoils ?
From what I've read they've a lot of negative pitching moment and…"
