Take a look in the vintage section for a thread about RC memories (can't post a link to it due to a very slow 3G connection here in Menorca) as your comments are mirrored by many other posts.
I never had a Brat, but did have a frog fro a while. My friend had a Brat and it always amazed me that the screw on shell weighed more than the car did!! Talk about top heavy, but "oh, what fun"
My introduction to RC was a tamiya grasshopper also with a 380 and until my bmax2 last year, the frog was my last 2wd drive car - is it any wonder I can't set a car up!!
