The AVANT LEGGERO S4L is a 4" lightweight Stretched X designed for extreme performance.   This little 4" racer is incredibily fast  with excellent flight characteristics and ultra fast acceleration.  It features a solid "Chamfered" 3.5mm unibody 3K twill weave carbon fiber main plate, 1.5mm top plate and 1.5mm camera mounting plate for simple construction and durability. The Stretched X layout gives you an extremely quick roll rate and stability during fast foward flight. The top plate cutout is larger enough to use any lenses with up to 18mm in diameter.  Plenty of room to install all the standard size components. Bare frame + hardware weighs only 48g.
