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 =...

We get a good amount of customers asking questions regarding the modification of their models.  Modifying your model is a common practice in this hobby and can be rewarding and even in some cases (mainly models that have been on the market for years), necessary.  However, there's a few things you should know before considering modifying a model you have purchased from us. The models we sell have specifically been designed for the components they come with.  This includes the power system, servos and landing gear.  Especially the more current models from Freewing and FlightLine RC where we have worked with them...

There's just something about a scale military jet in R/C form that excites the senses.  We have all fantasized about strapping in to the real thing but alas, outside of some media members and VIPs, that honor is bestowed only to a very select few in the world. So the next best thing is strapping on your radio and flying the model version!   Freewing has been delivering fantastic semi-scale military jets in the foam class for years, and their recent releases just keep getting better and better with modern day amenities like 9-to-12-blade EDF fans that offer a much more...

We've all watched the ubiquitous YouTube videos of First Person View (FPV) flights where a small camera is mounted to an R/C model taking the viewer along for the ride. I've been recording and publishing some of my flights for several years now.  It's quite easy and often rewarding, especially when I go back and watch videos from years ago, bringing back many a fond (and sometimes not so fond) memory.  Here are some tips and tricks I've learned along the way that hopefully you find helpful. Camera  When I first started filming my flights I was using the really...

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...

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...
