TRF421Xの付属２種類トップデッキ走り比べ。ハンドリングが激変しました！(Verification of TRF421X top deck two types.)

[Film No. 459] The TRF421X is becoming more and more impressive the more I drive it. Just like with the 421, I compared the two included top decks and measured the lap times. It seems like it could be a powerful weapon if used strategically depending on the circuit size and surface grip. #rccar #trf #421x
