Well as I'm finding out, electric brushless has been a pain too.
The number of different connector types, deans, xt, tamiya, the size of connectors, 3.5mm, 4mm, 5mm, 6.5mm.
"Oh yeah just buy a soldering iron its a necessity"
Esc melted within 10mins of running the car (around my lounge no less) .
Programming esc, lipo storage, discharge and protection etc.
Electric is a pain to learn from new. I have a nitro car due to arrive today, I wonder if I'll experience this amount of issues!
