Does anybody here run there 5b with no shell, to me the design is just awful for collecting crap and directing it in to places you just don't want it, and it just holds heat aswell, especially the bottom part around and under the engine, i was thinking off getting the fully sealed chassis, tr v2 full clutch set up (sealed), and sealed pullstart, mesh mod on flywheel and custom made windows that are longer in length and a custom plate over the steering servo, i no your never stop it all but i think that will improve the issue drasticly, i no some people will say why bother, but i don't like it anyways, i love to custom parts and i think it will look and hopfully perform better
