Starting to get a little frustrated with the TT02 I'm setting up for my 8-year old. The problem is we are making this a waterproof rain car because we have so many cars (mostly Tamiya) that we wanted to try something different.

I replaced the stock servo saver and thought that would cure the car's tendency to not go straight.

But, I had the car out yesterday in the driveway testing it for my son and it still veers off course unexpectedly.

The problem is I want to KEEP the nylon and plastic parts! Maybe I'm asking for the impossible. I'll update if I can find some solutions. Maybe ball bearings that are really sealed from water. Or what about ceramic? Are they waterproof?
