Not a bad idea Spaceclam, but I'm actually trying to avoid as many mechanical parts as possible. The idea is, it will be a light-weight tail-sitter setup (i.e. a quad rotor plan that takes off vertically, thus can also hover). When coming time to design (maybe build, pending sponsorship) the final VTOL, I plan to incorporate ducted electric rotors, most likely in a squished x-formation, with wing(s) parrallel to the horizon of the x. I'm not ruling out a + formation, however I have a gut feeling about greater stability with the x in horizontal flight. Will all be revealed in the maths! Also, because I am using a microcontroller, and making my own feedback, the x system isn't too hard to implement in code.

Possible layout looking down while hovering (or its flying towards you [X(]):

(X)\ /(X)
====================
(X)/ \(X)


or maybe:

=======(X)==(X)=======
|| ||
===(X)==(X)===

Won't know until I start the aerodynamic modelling.

Could even go the + layout like this:

(X)
=======(X)==(X)=======
(X)

By avoiding mechanical rudders, it significantly decreases weight. I must admit though, the control algorithm, the aerodynamics, and the transition between modes are going to be a challenge, but that’s what makes it fun!

To start with, I am going to make a Dragonflyer, no ducts and no wings, to get familiar with the gyroscopic control.

Anyways, I'm going to try avoid spending too much time her until exams are finished… so much work… so little time!

Catcha guys!
