RE: What are some must have rc's.
To the powerplant, maybe(clutch, basically - mostly bearings and the occasional replacement of shoes/springs, and the occasional needle adjustment.. But tuning is a learning curve, the mastering of which makes the hobby more rewarding.. Once you know what you're doing, it's not high maintenance..) But there's a hell of lot of maintenance with electric to the power source - the batteries.. - and peripheral stuff. Talking mostly about soldering.. (another learning curve I have ahead of me, but don't feel like bothering with just now..)
