210-R Assembly and Electronics Install Tutorial


The Speed Addict 250-R continues on with the same proven design as the 210-R/180-R but this time we go BIG! Fuselage geometry is exactly the same as our 210-R but the arms are longer to allow for 6" props. In addition we include optional arm braces in your kit to give you added toughness for freestyle and bashing applications. These optional arm braces use existing screws and can be added or removed at any time. The 250-R is a no compromise racer. It is designed for serious FPV pilots looking to compete at the highest level of drone racing competition. This is the Formula 1 equivalent of racing drones. When we set out to design this frame our focus was to make it faster and more agile than anything else currently available.  Before we started design work we set three primary design goals. 

  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 132 grams without arm braces. With arm braces frame weigh is 143 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 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 racing drones. To accomplish this we locate the power distribution board below the main frame plate. Bringing the PDB down in this way allows everything else above the PDB to be brought down as well. Including the flight controller, top fuselage deck plate, and most importantly the lithium battery. 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, its 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. But, durability is not compromised. The Speed Addict 250-R will accept very high power motor and prop combos. This is the ideal frame for 2206 or 2208 motors. 
  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 work. After months of work we finally accomplished our goal.
