Yokomo FA-19017S FANTOM HELIX RS SPEC Edition 17.5T

The new series of FANTOM motors is increasing the number of users at circuits all over the country and is gaining acclaim for its overwhelming speed! The HELIX RS SPEC edition complies with the ROAR standard, but is even more powerful with improvements in rotor balance, changes in case design, and a new design. There is little sense of stalling in corners, and it has achieved good results not only in the speed category but also in off-road stock races. We are currently applying for approval from JMRCA and plan to use it in races in the 2023 season. Please try it!
