Catalyst Machineworks SPEED ADDICT 210-R (V2) Quadcopter Frame

The Speed Addict 210-R (V2) is the successor to their original design that they brought to the market back in 2015. The original 210-R quickly become one of the most popular racing and freestyle frames in the industry. They did not let the popularity of the V1 throttle their desire for perfection. The new ‘V2’ is the result of customer feedback, team pilot testing/input, and additional experience gained from development of other designs. The goal with this new design is the ultimate uber delicious freestyle machine. Much Uber. Much delicious. Many of the same design principles that contribute to great flight characteristics for a racing specific drone also translate over to freestyle. Catalyst Machineworks was the first in the industry to use centralized battery placement and a “low profile” top deck. Their new V2 continues with that same design philosophy:

1. Place as much mass as possible close to the axes of roll and pitch rotation. 
2. Keep AUW “all up weight” low as possible while allowing for high power output. Dry frame weight is just over 100 grams. 
3. Place the center of gravity at the middle of the craft and sitting ON the same plane as the props.

Why are these three goals important and how do they work to improve the speed and agility of a freestyle/racing drone?

1. More force is required to rotate an object if that object’s mass concentration is located some distance from the axis of rotation. Conversely, less force is required to rotate said object the closer you bring the object’s mass toward the axis of rotation.  In other words, think of an ice skater spinning. As she brings her arms in tight towards her body she spins faster. As she moves her arms away from her body she spins slower. This technique of mass placement is used by engineers of full scale aerobatic craft looking to optimize maneuverability. This principle also applies to freestyle/racing drones. To accomplish this we locate the fuselage top deck as low as possible. This super low profile deck is one of the hallmarks of our design and keeps the largest contributor to overall craft weight (the lipo) as close as possible to the axis of roll and pitch rotation.
2. With any aircraft speed and agility are directly linked to power/weight ratio. The lighter the craft is compared to it’s overall power output the faster it will go. Additionally, it’s ability to make directional changes improves (a.k.a. agility). To keep weight down we employ a unibody “X” design. Unibody keeps overall frame weight low because less fasteners and carbon fiber are needed to join the frame together. In addition our use of carbon fiber is very efficient throughout the frame. Carbon fiber is located where it needs to be, with any unnecessary material removed. However, durability is not compromised.
3. A craft that is symmetric about it’s center of gravity has better flight characteristics than a front heavy or tail heavy design. In addition, its imperative to line up the center of gravity as close to the propeller plane as possible. When the two exist on the same plane there is a smaller moment to overcome during maneuvers resulting in more rapid directional changes. We accomplished this by the use of 3D Computer Aided Design. We assembled everything together in the CAD model. The program is used to calculate where the true center of gravity exists in 3D space. This information allowed us to alter the frame design and location of all the electronics and gear to move the center of gravity to the optimum location. This was an iterative process and required extensive design work.
