THECAR WHITE EDITION 25 HOUR TEST

THECAR WHITE EDITION 25 HOUR TEST

Last year I performed a durability test on THECar White Edition. I built a new car for the Nitro Challenge 2014 in February in USA, and then documented each time I drove the car. I only replaced parts that broke, in order to see how the wear rate is on the car, and if anything breaks due to stress and the rigours of racing. I practiced and raced on a variety of different tracks in various different conditions, from hot South Africa, to mild Michigan, and cool Finland. Here is a list of the races I did, of the option parts I fitted my car as new. Please read the article below!

Conclusion

Overall the car held up really well. If there is one area where JQRacing is amongst the very best, it is the durability of the car, specially the drivetrain parts. The gears are like new! When I first started, I actually used the same set of crown and pinion gears for two years! And they still looked like new. The gears have got to be the most durable part of the car.

Shocks also last forever it seems, I didn’t even replace shock bushings or o-rings. However, for best performance, the o-rings would need replacing as they swell.

The bearings are also very durable, and will not cause problems, or even require maintenance, unless you want to make sure you have the most free drivetrain possible. Just make sure you shim the wheel bearings properly so you eliminate slop, but do not stress the bearings.

Many people definitely over think and over work.

Many people definitely over think and over work. MY goal with the car is produce one which maximises your time spent driving and racing, and minimises the time spent maintaining it. So I want it to be easy to work on, and for it to require minimal maintenance, designing it in a way where the components last a long time.

There is no need to strip the car down at every race. Normally a well built car will last for many gallons. It will definitely last for a race meeting. At a race, it makes sense to keep the car clean, and check all hingepins and shock shafts to make sure they are straight, and of course check to make sure the critical screws are tight. There is no need to dissassemble every single nut and bolt. That actually INCREASES the risk of failure.

So my advice to you, build your cars with care one time, and do minor maintenance and checks at races.

As an example, after I have built a car, I never take apart the centre diff mount or the steering, and never remove the centre mount or engine mount from the chassis. I do it properly one time, and that lasts the car’s lifetime!

Maintenance Checklist

If you check the list of parts here, you will get a good idea of what parts are needed, and what parts are replaced every few gallons. You don’t HAVE to do this. You can just keep on running, but this guide shows what you need to do to keep the car in top shape! Remember that driving (crashing) style, and the tracks you run on could have a significant impact on some of the parts, such as chassis, arms, links and clutch for example. They may last a lot longer, but should not wear out any faster than this list.

    JQRacing - THEDriver Funding

    There is something that bothers me in this ranking, does it bother you? It stings my eyes .... This ranking shows the 25 best drivers in the world, but only car brands that can afford these drivers, and those brands are always the same. If it is only a question of money now, why don't we, the JQ customers, team drivers, and supporters, help to pay a driver for this list?
