John I have been Mr Grumpy this morning, no particular reason,
But I burst out laughing when you said you wanted to get your head around a few basics,
I and I humbly suggest most of us on this Forum are still waiting for that bolt of lightning from the heavens that finally shows us how to get an R/C Tank up and running first time every time without first having for no good reason to pretty much rebuild it, even though it was running just fine the last time it was shut down.
Welcome to the Forum
Enjoy this place and please ask all the questions you want especially ones about basics coz there are a lot of us would like the answers to those questions
Shaun.
