One thing I hate about 1:8th scale is the maintenance. There comes a point when everything is old and worn out enough to where the car just doesn’t feel right, and I can’t find my groove. I can’t reach that level required where you are in the zone, feeling the flow. It just doesn’t happen. When the engine is worn out, doesn’t idle right, powerband sucks, car is all worn out, you aren’t really going to make any progress!
Time to get a fresh engine, rebuild the car, and get back to work! 5 gallons in the last 3 weeks leaves it’s mark. This is one of the “work” parts of my job. I can think of a lot more fun things to do than wrenching past midnight.

the car still works great with worn parts, one good thing about the car, unlike others where your always adjusting something after the car takes a spill.
Switch to electric 😛
