With the new release of the HQ T4x2.5 and BetaFPV 20A Toothpick aio, BetaFPV and HQ provided us with these products to help them test prior to their release. We designed the TWIG MUTANT 4 around these two new exciting new products. The TWIG MUTANT 4 is a mutated TWIG frame that we have made some exciting new changes to as we did the new TWIG XL line up of frames . The frame is premium 3mm thick high grade T700 carbon cut along the weave and chamfered on both sides interior and exterior edges at .7mm. The frame is 160mm motor post to motor post and swing up to 4” props. The motor mounting is for 4-hole 9x9 or 12x12 motor mounts. The frame can accommodate a 20x20 stack or a whoop toothpick aio. With the 20A 2-4S whoop toothpick aio now available from BetaFPV it allows us to swing larger 4’ props as well as even use larger amp draw motors such as 1408 that we installed on our first prototype.
