SHOULD YOU UP­GRADE THAT PART TO ALU­MINUM?

RC Car Action - - HOW TO -

If you break the same part more than once, it’s only nat­u­ral to won­der if there isn’t a stronger ver­sion avail­able. Many brands of­fer alu­minum ver­sions of cer­tain plas­tic parts, and if they don’t, chances are the af­ter­mar­ket does. The most com­mon can­di­dates for alu­minum up­grades are arm mounts, C-hubs, rear hub car­ri­ers, and steer­ing knuck­les. If you’re break­ing these, con­sider mak­ing the alu­minum up­grade.

You may also find alu­minum arms for your model, but use cau­tion with these; un­like plas­tic arms that flex and re­turn to shape, alu­minum bends and stays bent. That’s not a prob­lem for items such as arm mounts and hub car­ri­ers, which don’t re­ally see bend­ing forces. But for sus­pen­sion arms, alu­minum is not the best choice. If you want them for style and you don’t crash into stuff, great. But if you’re out there break­ing plas­tic arms, you’ll bend alu­minum arms. Or that strong alu­minum arm will trans­fer crash loads to other parts, and they’ll break.

If you you’re hav­ing trou­ble with arms break­ing, see if RPM of­fers arms for your model. RPM uses an ex­tra-tough plas­tic, and the parts are gen­er­ally thicker and more flex­i­ble than stock, so they don’t break—and they don’t cause other parts to break, ei­ther.

Ready for ac­tion. RPM of­fers arms for tons of dif­fer­ent mod­els, and many come in col­ors. Here’s a com­plete set of RPM arms for the Traxxas T-maxx and E-maxx.
