Formula 550 (Stretched Quad)

Here is a complete quad design that I have done. The quad has very wide arms and is ideal for mounting a gimbal and camera. It also maintains the X layout for perfect stability and has a diagonal motor to motor size of 560mm making it more stable in windy flights. The top is designed to be sleek and aerodynamic for fast forward flying. I have included a gimbal mount that fits between the front arms and on my quad does not suffer from jello even though it is hard mounted.

I designed the chassis to easily hold a 20c 4S 5000mah battery for long flight times, and there is also room infront of the battery to mount fpv video tx and telemetry radio between the battery and the gimbal mount.

Here is a video of mine flying FPV. http://youtu.be/gogIP8V3nAY

I have included two chassis designs. One is for arms with M3 holes and the other is for arms with M2.5 holes.

There is also a flight controller mount that I use the blue anti vibration mounts from hobby king and also add 10 - 20
