450 Quad Kit (no flight control board): http://rctimer.com/index.php?gOo=goods_ ... oodsid=786

Assembly is pretty straight forward (very little instructions are included, but not really needed). The mounting of the flight control board is accomplished using nylon stand-offs for vibration isolation (purchased through RCTimer also). These quads can be a little tricky in assembly and most particularly "tuning". There are flight control parameters on the MultiWii board which you can tweak/tune to adjust the flight characteristics of the quad. To change these paramaters, a neat PC program is used and you simply connect the MultiWii board to your computer using a simple USB cable.
One of the better tuning guides I could find on the web is here:

My curent 450 quad has been tweaked to the max and flies unreal! I'm still not a good heli pilot so I still get messed up with orientation, etc... I'll get better, I just need more stick time... and most likely a few mishaps...

If you plan to build one, let me know and I'll try to help... 4 spinning blades has to be 4 times more fun,... right?
