90 mm brushless quad, 20mm stack

thingiverse

This is a compact 90 mm frame designed around a 20 mm core with an all-in-one (AIO) electronic speed controller (ESC) and 56 mm propellers. It also features a battery mount for a Turnigy nano-tech 300mah 2S 45-90C Lipo Pack, which fits perfectly within its design. The frame accommodates eleven-sized motors with 8.5 mm mounting holes. https://hobbyking.com/en_us/turnigy-nano-tech-300mah-2s-45-90c-lipo-pack.html Assembly is straightforward: First, insert the receiver into the bottom of the frame; there's a designated hole for the antenna to protrude. Next, place the ESC on top of the receiver and route the motor wires through the arms. The rest of the assembly follows naturally. https://www.youtube.com/watch?v=EkA2KNzaaaA Updates have been made to improve the design: Work continues on a camera mount for added functionality. New batteries arrived, which proved to be taller than anticipated; as a result, the battery holder has been enlarged. The OrangerX was initially too large, so the arms were reinforced with additional thickness to provide more space for the receiver and enhance structural integrity. Motor mounts have been modified. A camera mount (compatible with VM2751) has been added. Maiden flight took place; tuning efforts are ongoing due to subpar stock PIDs. Motor mounts have been strengthened further. A hole has been drilled in the base to accommodate power cables. Efforts are being made to resolve scaling issues.
