DT-03 build, mildly hopped up for fun driving and resilience to future ill-treatment.  This is, aside from a stock kit built with my son just the other week (same kit), a first return to rc for me since childhood (80s), so I'm clearly not blazing a trail here but I am making a few changes to stock, generally for functional (or perhaps pedantic and making no real life functional difference, depending on your outlook) rather than blingy reasons. And so I can learn from trying/changing stuff.
