There are ways to make plastic RC parts last longer as well. Reinforcing them with aluminum can help, though you should read our warning from earlier. Using hardier plastics helps. Sometimes, what helps most is avoidance. Vehicles consisting mostly or entirely of plastic parts should stay out of contests where they might get knocked around a lot. Speaking of contests: some people choose parts and materials intending to make their cars less vulnerable to damage. Other people make their choices based on what would make their vehicles lighter. Lower weight allows for higher speed, and reducing weight by just a fraction of an ounce can make the difference between winning and losing. Put simply, aluminum is heavier than plastic — by a wide margin. In a race between two cars, one with plastic parts, and one with aluminum parts, both otherwise identical, the former is more likely to win. Anyone interested in competitions that rely on speed may want to steer toward plastic.
No RC vehicle needs to consist solely of plastic or aluminum RC parts. You can mix the two in creative ways that minimize the weaknesses and maximize the strengths of the respective materials. Different RC veterans will have different opinions, but aluminum is advisable for bulkheads and caster blocks. Meanwhile, plastic is popular for shock towers and arms. We should repeat our warning from earlier that aluminum can transfer force from an impact to plastic, potentially damaging it in the process. Getting good strong plastic can help with that. Another piece of advice from our experience: if you expect to replace it often, you might as well get the metal. Finally, it is worth mentioning that
RC parts made of other materials are available as well.
