Electronics
Gyros correct RWD snap oversteer. A standalone ESC upgrade unlocks brushless compatibility and faster response.
Why it matters
At 1/27 scale, electronics are where handling becomes manageable. A gyro on an MR-03 or MR-04 is essentially mandatory above casual use. It corrects snap oversteer before you can react. A brushless-compatible ESC opens up the full motor upgrade path.
