Design Brief

Building on the success of the SLIPSTREAM 5 and taking the lessons learned from the design of the SLIPSTREAM HD 6, we present to you, the SLIPSTREAM HD 5 for the Connex Prosight. 

When looking at the Connex components, I've always been impressed at the build quality and precision of the parts. HD FPV has been the dream since I started working on drones in late 2011 and Connex has finally delivered on the dream of people in the industry like myself, and the expectations of the general public who experience HD on the norm. 

The design concept came down to one decision. A top mounted VTX vs a bottom mounted VTX. There are clear advantages to both. Top mounting is better for a sporty CG and for cooling, while bottom mounting allows for a smaller top-plate and a protected VTX. 

What ultimately swayed me was aero and handling. In the field of aero, the equation is simple: the larger the top-plate, the greater the drag. The significant demands we put on our frames in terms of speed and aerodynamics means that drag is becoming a greater concern. With motors available today 100mph is easy with such a setup. A larger top plate acts as an air-brake, slowing you down and limiting your acceleration and top speed.  

The down-side to a bottom mount VTX is that it drops the battery several millimeters, and therefore the CG, below the center of thrust. The impact of this is slightly slower, softer responsiveness to the frame. In terms of drawbacks, this could be a serious one. However, I realized that given the torque and power being generated by today's motors this would largely be mitigated by running a 2206 motor (or equivalent 2205 like the EMAX RS-S) or a 2207. Given the trend towards constantly more powerful motors, I saw this as a minimal trade in terms of design over worse aerodynamic tendencies.  

Built upon the Slipstream geometry, this should prove to be a very fast HD quad.
