Understanding and Maximizing the AE-5 ESC

blog_ae52

Wouldn’t it be great if ease of use didn’t mean a sacrifice in sophistication and performance? When it comes to electronics, there is often an unfortunate connection there. Axial purposely made the AE-5 ESC an exception. It is waterproof–a huge plus–and features two must have adjustments: LiPo cutoff and drag brake. An addition plus is that the AE-5 retails for only $45.

The AE-5 is a brushed motor electronic speed control, or ESC. It can only control brushed motors. While intended for crawling applications mainly, it is not limited to high-turn motors. When paired with a 2S LiPo battery, it can handle as much as a 12-turn motor. On 3S, 18-turn is the maximum. Note that the lower the number of turns, the more amps a motor draws and the faster it is. Vehicles built for climbing and crawling generally need more torque or power than speed and go with higher turn motors such as Axial’s 55-turn motor (AX24007). As indicated, the AE-5 can handle 2S and 3S LiPo batteries. It can also be used with NiMH batteries. It’s worth noting that the AE-5 can handle up to a 9-cell NiMH (10.8 volts). Since NiMH packs are heavier than LiPo, if this was matched with the above mentioned 55-turn motor, the truck it was installed in would be a very capable puller.

We have all heard that water and electronics don’t mix, so the fact that the AE-5 is waterproof from the factory is an obviously huge benefit. This feature will allow you to tackle a wide variety of terrain and obstacles with confidence. Always make sure the rest of your electronics (and the vehicle) are well protected. You can learn more about waterproofing in this post.

The LiPo cutoff feature allows you to safely run LiPo cells. LiPo batteries absolutely must be run in this mode. This feature can also be switch to NiMH to allow maximum power out of those cells. This isn’t new to Axial ESCs, but what is new is how incredibly easy it is to program the AE-5. Instead of a series of steps performed via the transmitter or a computer, the AE-5 is adjusted via simple plugs, called jumpers. It literally takes seconds and is just about foolproof. To switch from the default LiPo mode, remove the plug and move it over slightly and reinstall. It couldn’t be easier.

While correctly matching a setting for the type of battery you are using is pretty straightforward, the drag brake feature might be a little bit more enigmatic. Drag brake is the opposite of coasting. If you have no drag brake, when you went to neutral (no throttle or brake inout via the transmitter’s trigger), the vehicle would coast or free roll and slow to a stop. Drag brake automatically applies braking force at neutral. When rock crawling, this is essential for control on hills and around gates or technical sections where precision is required. Without drag brakes, a crawler would be next to impossible to control at slow speeds. It would roll on hills, off ledges, and into gates. The AE-5 comes with 100% drag brakes as the default setting. There is an optional 50% drag brake setting on the AE-5. This is just as easy to adjust as the LiPo setting. Just move the plug and the setting is changed. So, if drag brakes are so good, why would you want only 50% strength? High speed applications such as rock racing will benefit from lower strength drag brakes. Lower strength drake brakes will allow to coast through turns faster. A far more noticeable difference will be when jumping. This is because drag brakes in the air will cause the nose of the vehicle to drop. Review this post on jumping to better understand this concept. So, if you’re rock racing and may encounter jumps, try reducing the drag brakes setting to 50%. And since rock racing is more about speed than finesse, you won’t have to worry about precise control around gates or on hills.

Axial – The Official R/C vehicles of Ultra4 Racing – King of the Hammers 2015

blog_axialg6koh

FOR IMMEDIATE RELEASE:
(Mission Viejo, CA) January 14, 2015.

Axial R/C Inc., A subsidiary of Hobbico Inc., is proud to announce Axial as the Official R/C Vehicles of Ultra4 / King of the Hammers for 2015.

Ultra4 Racing is the latest and greatest off road motorsport event on earth. This style of racing challenges man to a duel with the elements. Unlike standard off road racing in a stadium or in the wide open desert, Ultra4 vehicles face challenges that no other motorsport demands. Competitors are not only made to cross vast areas of open desert, they also travel up boulder strewn canyons and negotiate terrain that appears impassable. To compete in such a demanding environment, competitors build custom four wheel drive vehicles that are made to crawl over the harshest terrain, then conquer the wide open desert at exhilarating triple digit speeds. This element of automotive enthusiasm is precisely what Axial R/C has set out to deliver in 1:10 scale, so the relationship between Axial R/C and Ultra4 is a very natural fit.

Axial’s roots are directly tied to motorsports, especially competitive rock crawling. As full size competitive rock crawling transcended into what is now rock racing, the sport became globally recognized in a short five years, most notably the King of the Hammers [KOH] held annually in Johnson Valley, California. Axial followed suit with its own version of vehicles that translated well within this segment of the off road community. Axial has been very offroad lifestyle driven and fits perfectly with Ultra4 and the King of the Hammers event which is the mecca of enthusiasts pushing the boundaries of rock racing. Axial will be on site at the 2015 King of the Hammers offering enthusiasts an opportunity to experience the endless fun that these rock racing and trail navigating R/Cs have to offer.

On the Saturday following KOH [Feb 7th], there will be a radio controlled version of King of the Hammers as Axial hosts the RECON Ultra4 G6 at King of the Hammers.

About Ultra4
Ultra4 Racing is the official website of Hammerking Productions. The founders of Hammerking are the force behind the toughest one-day off-road race on the planet: King of The Hammers. King of the Hammers takes place each year in February, on public lands in Johnson Valley, CA. The race has evolved from 12 teams racing for bragging rights and a case of beer, to more than 150 teams competing before thousands of fans both live and online. Due to the incredible success of King of the Hammers, Hammerking has created an equally difficult off-road endurance race called The Stampede which occurs annually in Reno, NV.

In addition to these races, Hammerking has established a racing class known as the Ultra4 class. The defining characteristic of this class is that all cars must be capable of 4-wheel drive. Beyond that, the class is unlimited, which means these cars come in all shapes and sizes and are capable of speeds over 100+ MPH and still contain gear ratios as low as 100 to 1 for technical rock crawling.

To give these cars and their drivers a chance to showcase their unique capabilities, Hammerking has formed the Ultra4 Racing series. The series challenges drivers to compete in a wide variety of terrain from endurance desert racing to competition-style rock crawls to short course racing. Hammerking currently produces five of the six races in the series on their own. The races take place on both public lands and in private motorsports parks across the country including: Exit 28 Motorsports Park in Nevada, Rausch Creek in Pennsylvania and Miller Motorsports Park in Utah.

Hammerking Productions has also produced three full-length feature films chronicling the first three King of the Hammers races. These award winning movies have helped shine a spotlight on this new form of racing throughout the world. Currently, fans are eagerly awaiting the release of Hammerking’s fourth production which will be coming to theaters and DVD by mid 2011.
