Finally, I got the Tamiya TRF 421 kit and completed building the kit.
TBH, the quality of the kit is excellent as always but it is hard to say it's better than other brands' racing kits.
One thing I was impressed by about the TRF 421 is the pre-included optional parts such as aluminum diff housing, aluminum motor fan mount, one-piece and separate top decks, etc.
You just need to purchase other brands' spring sets.
I am planning to roll out this thing of beauty in my local track, 360 Fordham Hobbies soon, and can't wait to see that!
Stay tuned and see you next video!
