"As the inventor of the deep H-block and pioneer of the freestyle frame concept, Ground Control decided to take the concept to a whole new level: Center piece of the Formula 1 frame is an oversized H-Block which extends almost over 80 % of the frame and provides a true cost efficient solution to replace it when worn down. This concept was made possible by a patented 3-point attachment system which secures the h-block all the way through the base of the frame and the sole of the boot. This creates a frame which is unmatched in stiffness, strength and durability. Special sichel shaped axle bolt heads increase the crucial material thickness below the axle holes and allow convenient one and operation.".
