What is RC crawling
RC crawling needs you to have patience as these buggies run very slowly, but steadily. If you are an off-roader car driver, you are used to driving your RC buggy to go through rocky paths at a high speed. On the other hand, RC crawling is in a totally different world; it is an extreme form of RC off-road driving. With these crawlers, you will need to go through deep slopes at a very slow speed as steady speed is necessary when they try to cross the gaps between deep rocks; otherwise, they will fall to the ground and fail a competition.
Power vs speed
You will have a different setup for your crawlers as RC crawling value power over speed. In fact, hobbyists usually use a brushed motor instead of a brushless motor as the brushed motors are cheap and powerful enough to handle the road conditions. For a brushed motor, a turn count between 27T and 55T is the popular choice for this type of activity. Any turn count above 55T will be very powerful, but extremely slow. Thus, finding the ultimate balance between speed and torque (the power to climb) is essential as you do want your crawler to have at least human walking speed. Then, you can follow your crawler comfortably while driving. On the other hand, if you do want to use a brushless motor, remember to use the sensored ones so that your truck can get enough torque from the 0 RPM and smoother transition from the low speed. Indeed, for RC crawling, a sensored motor/ESC is mandatory.
The main purpose of crawling is to drive these crawlers to go to where has a regular off-road car never gone before. When you compare a crawler with any Tamiya’s off-road car, you will think a crawler is a durable beast in the wild while Tamiya’s off-road cars are only toy cars.
A flexible suspension system enables a crawler to perform well in harsh roads. It increases the ability to move easily in tight corners. If you have any idea how to set up your RC crawler, please share in my forums.
