Do as Tom mentioned, there is probably someone close to you that can tell what condition your new stuff is in. Example would be the starter you got. The engines could be a bit stiff from hardening castor or the battery for the starter isn't up to snuff? Just simple little things.
A lot of clubs also have a club trainer and a buddy box system to train you, that way you don't need to buy anything and after you solo and get some stick time you may fit right into the Extras without too much trouble.
Wish I had a little .48fs, I'm reverting in my old age and getting back into the smaller planes, I could use that engine.
