In a nutshell.. Not much of anything.. Stuff like generic/aftermarket engines, bodies, tires, wheels, wheel nuts, bearings,screws, etc. will pretty much work no problem, but as far as dog bones and suspension arms, there pretty much sized specifically for Redcat/Himoto/Exceed/Acme vehicles.. I dont know where ya get your parts, but if you look at some of the aftermarket Redcatvendors on this site, for instance, www.urchobby.com you'll find that they have much better prices than dealing withRedcat directly, and they get the stuff shipped out in a hurry, and for not much S/H cost.. I've found I usually get my parts within 5 days of ordering, and the savings over the LSH cover the shipping fee's in most cases.. Welcome to the site!! There's alot of good guys and good vendors on this site!They'll take care of ya!
