there is the first draft of a quad design i want to build this summer. It's a  project made with the coloboration  Maxime Carrier.

The objective is only to make a high performance wierd looking quadcopter XD.

2 low speed big fan for stationary fly and 2 rotary high speed smaller fan for stabilisation and high speed thrust.

Now de fun part is to design it for real. XD

leave your comment about this  design XD .

p.s. sorry for my bad grammar

Your grammar is already horrible in french anyway :P

How do you control roll... on that thing?

Nice use of Inventor.  

I've had a similar idea but also different:  mine involves a quad with the "endcaps", as I call them (the end of each arm of a typical quad which holds the motor/ prop combo) to be on a swivel, that way the quad can be dropped in a vertical orientation and it can slowly ease itself into horizontal orientation over time.  Or at least to have 1 prop (The relative top one in the vertical storage orientation) do that to still provide some thrust while the quad is falling from a high altitude deployment.

Seems like roll would be a issue... humm

Side EDF can tilt, but I'm not sure about pitch in flight (airplane mode)
Comment by Xavier Simard-Lecours on March 4, 2013 at 2:52pm
My bad i probably should draw the 2 smaller fan at different angle to show they can rotate on 180 .Te roll is control by tilting independatly the 2 smaller fan. It's produce that way a momentum to stabilise the design on stationary fly

Have toi post some draft of your design Ray k :D ? It's look interesting

Is it doing a Knife edge maneuver? What keeps it from falling out of the Sky? ( don't worry about your grammar  I am sure if we went  your home town we would nearly all sound  bad!)  it looks  it is from outer space or a hoover craft on it;s side ! Good Job! Have a Great Day! Bon Soir

We prefer the 'drop the anchor maneuver :D everything could fly with enough power, I think Xavier want to stay it in air using fuselage to generate lift, maybe I could be better to add small wing on each side so he make it to go really fast but still able to land safely vertically (we are flying no where, we have no decent runway unfortunatelly :( )

@Carl La france :the idea is from stationary to apromatly 80kph it's only the big fan trust stabilized with the smaller tilting fan. at 80 kph the aerodynamic shape start produce a mesurable lift and over 140 kph the lift only make it stay in the air and in my dream it's could fly at 200 kph XD. It's the objective XD now i have a couple of hours of modeling and calculus before i can achieved it but .... challenge is always fun :D. I'ts a really raw draft it's not actualy the final form. but the final one Can't take off or land like a conventional aircraft the minimum lift speed is too high.

have a nice day you too ;)
