Sometimes there are questions you have about RC you’ve always wondered, but for one reason or another, never asked.  Whether you’re a seasoned veteran or brand new, we’re going to bring you up to speed. Have a question you’ve been wanting to ask? Let us know in the comments! Often mentioned, but rarely easily explained, is the great Brushed vs. Brushless Motor question. In the hopes of keeping you from saying “forget this…just give me a bottle of nitro and an engine”, we want to shed some light on this topic. This can have a big impact on which truck you choose, and while conversion kits are able to take you from one to the other, it’s cheaper and easier to pick the one you want from the beginning. So let’s start with the basics… A brushed motor has been around for a few centuries and is one of the simplest types of motors. Performance is often expressed in ‘Turns’ (number of times the wire is wrapped around the armature core – e.g. “19T”) and ‘Winds’ (number of strands in the wire, typically 1-4).

The number of turns you want depends on your needs: lower turns means higher top speed but less torque, while higher turns means lower top speed but increased torque. Two permanent/stationary magnets sit inside the ‘Can’ (outer case) of the motor. The battery is connected to two ‘Brushes’ which make contact with the copper ‘Commutator’. The ‘Armature’ is connected to the commutator and consists of a core that is wrapped multiple times with wires.parrot ar drone pinion gear Electricity is transferred from the battery, to the commutator, and then to the wrapped wires. macdev drone dx vs geoAs power flows through this electromagnet, the ends of the armature become ‘Poles’.  ar drone gps kaufen

It is the attraction and repulsion between these poles and the permanent magnets on the edge of the can that turn the axle. This polarization of the wires flips as the armature turns and the two halves of the commutator make contact with either of the brushes, beginning the cycle all over again (and move your truck). While cheaper, there are drawbacks with brushed motors (and why many use conversion kits to take their trucks from brushed to brushless) mostly due to friction between the brushes and the commutator. parrot ar drone unboxingWhere you have friction, you have heat and degradation, which means frequent maintenance. parrot ar drone portataAs motor-wear increases, imperfections on the commutator develop and periodically break contact with the brushes, which means momentary loss of power. ar drone 2 hull template

In a backyard bash, this may be unnoticeable, but in a race this can mean the difference between winning or losing. This can be solved by ripping open your motor and retooling/replacing components on a regular basis, but can get expensive and labor-intensive when you’re in between races. Enter the solution: brushless motors. A brushless motor is the inverse of the brushed motor and performance is expressed in ‘Kv’, indicating how many volts are required for a certain RPM (2200Kv motor x 3V = 6600RPM). Instead of stationary magnets and spinning wires, you have stationary wires and a spinning magnet, with the key benefit of no friction. Electricity is fed from the battery and controlled by the Electronic Speed Control (ESC) to create the electromagnetic attraction/repulsion, the wires being polarized at different times (as determined by the ESC) to drive the field magnet and axle. Make sure you choose the right Motor / ESC combination if you’re putting in new brushless parts.

Some motors have sensors to communicate the position of rotation for improved precision, though many companies like HPI have chosen to go sensorless in their Flux series since the small increase in performance often won’t be needed compared to the increased cost.At RPM, we pride ourselves on offering the best selection of tools, wheels, and vehicle performance parts. This section of our web site includes our complete product catalog. You will find our products categorized by "type of product" below and to the right. We have three easy ways to find what you're looking for. First, if you know exactly what you're looking for, simply choose the category you're interested in to go right to it. Alternately, we have a "Make / Model" search to the right as well. Choose the manufacturer of your vehicle, followed by the specific model and everything you see from that point forward will be specifically for your ride! Click the "reset vehicle" link to reset the "Make / Model" search to "everything".

Lastly, above and to the right, we have a very powerful search feature. Simply type in a few key words to list everything that fits within your search query. This works great if you want a listing of everything for your specific vehicle as well! Most product listings include at least one or more photos and description of the item as well as part numbers and suggested retail pricing. By clicking on each photo, you can access a high-resolution photo of the product, allowing you to fully appreciate the attention to detail we place in designing and manufacturing each and every part. Our goal at High Spirits is to provide everything needed to make the learning experience fun and enjoyable. For this reason, we have created the Center for Instruction! This valuable resource includes hundreds of free tutorial videos, fingering charts, sound samples for each of our flutes, instructions regarding the care of the flute, and general support materials.
