Not a problem
I have broken one rear plate. I hit hard enough that some thing had to break. I found checking all screws once a week helps keep from breaking things too. Two weeks ago I hit a board hard enough to break my rear wheel and bend the left clamp on hub. Gotta love those graphite axles!
I use steel countersunk Allan head screws in my chasis.
Old school and new front ends are discussed here a lot. Basicly the old one is more solid, cheaper lighter, and simpler. I run the new one right now, but might try the old one too. New front end is supposed to have more steering IN the corner. Maybe a little more agressive.
