i bent another stock front hinge pin and nearly broke another rpm arm and almost broke my bulkhead again. i like the stock hinge pins because they have no slop but they seem to get bent easy causing stress and causing my rpm arms to bend and break along with my stock bulkhead. i know i can get an aluminum bulkhead which i will probably do but will i need new screws? will i need some type of locktight for them and can i get the locktight at my local hobby shop? and is there a good aftermarket upgrade for my hinge pins that fit like stock but are stronger?
