    Regarding The Dynam V2 Retracts

    Posted by Motion RC on |

  • Category: Electronics
  • It's important for customers to note that the new Dynam V2 retracts have the same 10-12 second delay as the V1 retracts.  Although the internal mechanism has been upgraded and improved, the delay is the same.  Once you plug in your retracts, wait 10-12 seconds and then you should hear a "click".  Once you hear the click the retracts are ready for cycling and should work perfectly. This delay appears to apply to digital radios only.  Using a non-computer radio (like the Gavin 6A as example) causes no delay with the V2 retracts.   We recommend that you test your Dynam V2 retracts...

    LiPo Charger Wattage vs Amperage - max charging rates explained

  • Charger Wattage vs Amperage - max charging rates explained Many chargers are rated with a max wattage and amperage but these maximums cannot be realized in all situations with batteries of all sizes. How can you decipher the specifications to find the maximum amperage capability of a charger for various battery sizes? AMPS = WATTS / VOLTS Using this formula allows us to figure out a charger’s maximum amperage capability for batteries of different sizes. First, recall the voltages of various size LiPo batteries: 2 cell LiPo = 8.4V max 3 cell LiPo = 12.6V max 4 cell LiPo =...

    Gyros: Clearing Up The Stigma

    Posted by Todd Breda on |

  • Category: Electronics
  • One of the most unfortunate things to happen in this modern era of high tech in our R/C hobby is the misconception surrounding gyros, especially from some of the older generations. The prevailing narrative is that gyros "control" your model, somehow removing you as the Pilot In Command.  Or that a gyro is recommended because your stick skills might be lacking.   Neither of these narratives are true.  A gyro in its simplest form is a device that helps counter the effects of variable wind/weather by making slight adjustments to the control surfaces.  These adjustments in no way hamper or override...

    Are You Initializing Your ESC?

    Posted by Todd Breda on |

  • Category: Electronics
  • A very common reason a customer might call us is because they can't get their ESC to work.  They bought a new airplane from us, receive the shipping package, excitedly put it together, following the instructions, charging the battery, binding the airplane to their radio, checking their control surfaces that are working, then they add some power to the throttle to check the motor and... Nothing. Many assume they have a faulty ESC.  They call up and in 99.9% of the cases, one of our Customer Support Team Members kindly explains the problem, which is that the ESC has not been...

    Understanding Brushless RC Motor Specifications

    Posted by Motion RC on |

  • Category: Electronics
  • Brushless motors use a standard numbering scheme to describe their physical size and kV rating. For example: let's assume we have a 5055-3000kV Brushless Outrunner Motor. We break the numbers out as follows:  [50] [55] - [3000] [50] The first two numbers represent the diameter of the motor's housing in millimeters; in this example 50mm [55] The second two numbers represent the length of the motor housing in millimeters; in this example 55mm [3000] The numbers after the dash represent the kV rating of the motor; in this example 3000kV. The kV rating (not to be confused with kilo-volt) is the...
