XLR-4 Design Specs:

XLR-4 is lightweight, 185mm stretched X layout, racing quad! It is designed to use most standard size FPV components and electronics, but is specifically designed for T-Motor F30 (1806 size) 2800kv motors and 4" props. The lightweight design also incorporates a minimalistic arm approach intended for use with a central mounted 4in1 ESC. The XLR-4 Prototype frame weighs a scant 65g, and can be easily built up to less than 250g without battery. My personal prototype was 240g using standard components and retaining all steel hardware. Using an 1806 power system also allows for the use of smaller capacity batteries, to create an even lighter overall setup. A typical 850-1000mAh high C rating 4S battery will be adequate for most racing situations (2-2:30min heats). When everything is combined, this creates an agile 4" racer that is roughly 350g all up with battery.
