The Simple Answer
The answer depends on who you are and what do you want your RC car to do. However, one thing we need to keep in mind is that aluminium parts are usually better than plastic parts. I will discuss the reasons for the improved performance they can bring to an RC car.
Why Do You Want Premium RC Parts?
Usually, RC parts made of aluminium, graphite and carbon fibre are more expensive than the ones made of plastic materials. The reason for the higher prices is valid. These premium parts can increase value of an RC car in general. With these parts, its performance can go up and total weight can go down. These parts can also make a car more durable and can give a more scaled look of it.
Aluminium Parts are stronger
Aluminium parts are always stronger than plastic parts so they are more expensive than the ones made of plastic. Both can be combined with other compounds to form stronger materials. However, aluminium is still the stronger among the two. In the RC industry, we usually use two types of aluminium for making premium option parts. They are 6061 and 7075. They are also important elements for making our modern full-size vehicles, ships and aeroplanes. One thing we should remember is that Aluminum 7075 is more expensive than aluminium 6061 as 7075 is strongest available in the market.
Which Parts Should You Use Aluminium?
Using aluminium alloy can always increase our RC car strength. That is important as we drift, bash and crawl with our RC car. Our RC cars will wear out eventually. Even the most skilful drivers will once in a while hit his RC car against the walls or some solid objects. Aluminium parts can extend the RC car’s durability by at least 4 times more than plastic. You should consider replacing the plastic bulkhead, the chassis brace, the servo mounts with something made of aluminium. These parts receive the stress the most. Having these aluminium parts, everything will stay in place even you have a serious crash.
To Achieve Repeatability of Performance
As a professional driver, you will want your RC car always in its peak performance. An unnoticed damaged plastic part in the wheels can negatively affect your car’s chance for winning in a race. Thus, upgrading your RC car with aluminium parts are inevitable. You have to use your experience to judge how many aluminium parts to use in your car as plastic parts have higher elasticity and less expensive than its aluminium counterparts.
Aluminum Parts Give More Precise Turnings
When you have shocks made of aluminium, your car will run on the road more efficiently due to its harder springs. Also, the aluminium shock towers with different tuning holes can allow for a better angle when turning. This feature usually comes only with aluminium shocks.
As an RC hobbyist, we always want our RC car at its peak performance, so that we can enjoy this excitement as much as possible. For this reason, if we have the budget, we should consider upgrading our car with aluminium parts; the aluminium parts offer many advantages over its plastic counterparts.
