The Mamba Monster is finally here!
Long rumored, occasionally seen at trade shows, Castle’s elusive 1/8th scale Mamba Monster Brushless ESC is finally available to the public. Castle has used all of their tricks to deliver stunning power for monster trucks and 1/8th buggy conversions.
The Mamba Monster handles up to 6S LIPO input (25.2 Volts MAX). It has a switching BEC circuit onboard to provide plenty of power for your receiver and servos. Don’t worry about the amp rating, nothing even comes close to the real world performance of the Castle controllers, and Mamba Monster is no exception. We’ve hit 60 mph with RC vehicles that have absolutely no business doing 60 mph. (And we were doing it in a 20 mph zone!).
Mamba Monster is designed to keep its cool while it pounds your truck. Castle refused to cut corners on the design or the components, the electronic and thermodynamic fundamentals are right to begin with. Castle then wrings a bit more power out by using a high efficiency heat sink PLUS an integrated cooling fan to make sure you finish the race. Thermals are for the other guys.
Mamba Monster ESCs come with huge 6.5mm gold plated bullet connectors for reliable power transfer and simple installation. We’ve even thrown in a Castle Link USB adapter* so you can tame the Monster by adjusting the really useful settings using your Windows PC.
*USB cable not included.
Two incredible motor choices!
Based on Steve Neu’s awesome 15 series motor, the Neu-Castle 2200 and 2650 are works of mechanical art. They both feature high quality oversized bearings, sintered Neodymium magnets, superior electromagnetic design, and rigorous engineering control in our own factory resulting in a Monster motor we can put our name on.
Neu-Castle 2650 KV – Intended for 4S (16.8 Volt) operation. Ideal for 1/8th buggy conversions. The 2650 is 68mm long.
Neu-Castle 2200 KV – Intended for up to 6S (25.2 Volt) operation. Incredible in monster trucks with up to 6S lipo packs (4s lipo is the sweet spot), and works great in 1/8 Truggies as well. The 2200 is 75mm long making it capable of handling more power than the 2650. This one is the bad boy!
The efficiency of a motor determines its quality. Higher efficiency means better design and high quality components. The higher the efficiency of the motor the more power it can produce before it overheats. Here’s a little math, we promise it won’t hurt. Say you are laying down 1,000 watts, (about 1 ¼ horsepower), and your motor is 70% efficient. That means you are turning 300 watts into heat. Ever grab a 300 watt light bulb? If the motor is 85% efficient it only burns 150 watts as heat. More power goes to the wheels and the motor runs cooler and able to put out even more power when needed.
Mamba Monster systems typically pull 4,000-5,000 watts (5 to 6 horsepower) under acceleration. The Neu-Castle motors are some of the highest efficiency motors that we have ever tested; they are up to 85%+ efficient on our test rig. The more common Asian motors tend to show in the mid to high 70’s. At those power levels, one single point equals about 50 watts of heat! You know that soldering iron on your workbench? It’s maxed out at 50 watts. That’s a lot of heat; now consider wasting several times that much heat inside your vehicle. Neu-Castle motors can therefore put out significantly more power for longer periods than less efficient motors. Go ahead, run the motor you have on the shelf, we have a feeling you will find its heat limits quickly.
It’s always better to reduce the heat generated in an electric power system is by better engineering than to try and cool things with fans and other gimmicks. Sure, a fan can get you a few degrees, but it is much better to have a superior design to begin with.
