Who has experience building fast PWD cars? I just finished building some cars for my boys but I’m wondering what go-fast tips might be out there besides the usual.
I know the basics:
Get the weight up to 5 oz, put most of the weight over the rear axle
File, sand, and polish the axles to make them as smooth as possible
Lightly sand the wheels with a drill and a wheel turning mandrel thing. (our pack’s rules prohibit any wheel mods besides light sanding)
Lots of graphite lube in the hubs, axles should be smooth and lubed enough so wheels spin for 25-30 seconds.
What other tips do you have that maybe aren’t widely known? I read up on rail riding a bit, but it seems like one of those things that will hurt you more than it helps unless the car is setup perfectly, so I just try to get it aligned so it will roll perfectly straight.
Oh, I also left the axle area unpainted and sanded it and rubbed graphite into the wood.
What did I miss? Please help! Race on Saturday.
