After months of reading and learning from you guys, I’ve finally completed my X4 '26 for the 13.5T class. Just wanted to say a massive thank you for all the tips and inspiration that made this build possible.
Can’t wait for the first shakedown at the track!
Hi everyone,
I'm completely new to 1/10 touring cars and I'm currently building my first kit, an Xray X4 '26. I'm planning to race in the 13.5T Pro Stock (Blinky) class on asphalt/carpet.
I quickly realized that the kit's stock 110T spur gear is mostly for Modified and won't work for 13.5T. I know the X4 chassis has a strict "total tooth count" limit for the motor slide.
I need to buy a new 64P spur gear and a set of 3 pinions to cover different track layouts, but I'm completely lost on what sizes to get to ensure everything fits physically and keeps the motor temps safe.
Could you recommend a specific Spur Gear size (64P) and 3 Pinion sizes to get me started? I'm looking for:
1 "Neutral" pinion: An all-around gear for medium/club tracks.
1 "Short" pinion: For tight, twisty, and technical tracks.
1 "Long" pinion: For fast, open tracks with long straights.
Also, do I strictly need to buy "narrow" pinions?
Any exact tooth count combinations or brand recommendations would be hugely appreciated. Thanks in advance!
