The " TWIG XL" is a larger version of our original "Speed Racer TWIG". This enlarged design has a frame size of 140mm at 3mm and comes in around 20 grams. Typical completed builds (depending on components) come in around 100-115 grams before your battery of choice. We have (3) frame choices available. The original TRUE, STRETCH-X design preferred by Racers, and even a WIDE-X for you Freestylers and you guys that prefer HD cameras with no props in view.
