I've had a hard time finding current official myself. If I had to describe them from my understanding, the large bullet points were:
•*70T motor
• Autoscale body (no pan or lexan)
• Normal rubber tires, no sauce.
• Minimum 3 people in heats/races.
I recall almost everything else was acceptable. I don't remember any restrictions on parts, from double A-arm, ball diffs, disc and oil spring dampers, FETs, etc.
I have a PDF copy downloaded on my phone for season 23. I tried to attach the file, but it didn't work. It might be beyond the size limit. A couple other things:
You also must use NIMH batteries.
you are allowed to use brushless motors as long as they are 5600 kv or lower.
You are also allowed to use the stock Kyosho brushed motors.
No oversized wings or major body mods (you may grind off air dams to prevent it from catching on RCP
