Hi there welcome back, 

Here is a little picture of the first version of my quad hybrid projet

It's a version to allow "Maxime carrier" to crash it 1 or 2 time before it's broke XD.

The design of the 2 rotating propeler is pending until i got the missing part. beteween 2 and 3 week. and if we can make it flight straight the next step is amovible airfoil aérodynamic design for high speed flight. it' a really tuff design ready to get strong impact of aproximatly 9G before major repair.

That's a short post to get you informed 

Have a nice day

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 .
