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.
The " TWIG MUTANT 4" is our mutated TWIG frame that has been enlarged to accommodate 4" props. The frame is 160mm by 3mm thick and comes in at only 22 grams. Typical completed builds (depending on components) come in around 130-150g before your battery of choice. The new HQ T4X2.5 bi-blade propellers are highly recommended since they are so light, smooth, and efficient.
