My dad just gave me his Traxxas Rustler 2.5
Set in his garage for 5 or 6 years.
Had to buy new drive shaft yokes, wire harness/power switch, and both servos... Put around $100 into it with fuel and little things...(which seems dumb now but it's got some sentimental value)
Put it all back together, got it set up and it started on the first try.
(Still have the old antenna control...gotta upgrade lol )
