If anyone wants one of these receiver setups, let me know and I'll add them to my order. Anthony, these will work with your Spektrum Radio from your Blade MCX<br><br><div class="gmail_quote">On Fri, Jun 3, 2011 at 12:47 PM, Corey McGuire <span dir="ltr"><<a href="mailto:coreyfro@coreyfro.com">coreyfro@coreyfro.com</a>></span> wrote:<br>

<br><br>New product from hobby king.<br><a href="http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13418" target="_blank">http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13418</a><br><br>
The
concept of a "Satellite receiver" (meaning secondary receiver to feed
data to the primary receiver) is not new. They are used in the quite
likely event that your RC aircraft is flipping around and it's main
antenna's polarity no longer matches your transmitter's, thus making
your effective range drop sharply in an instant. Add a "Satellite
receiver" oriented on another axis/plane and this problem is lessened.<br>
<br>Unlike primary receivers, these satellite receivers do not drive
servos or speak PWM. Instead of 2 to 10 PWM streams as output, they
have one PPM stream that contains all the information of all the
channels on one data line.<br>
<br>This means, if you want to control a robot using a pro/hobby grade
wireless protocol, instead of trying to capture up to 10 different PWM
signals simultaneously, you only need to capture one PPM signal.<br><br>PPM
is standard. All radios output it through their Trainer/DSC ports.
There are dozens of Arduino projects that speak PPM. Now that we have a
cheap wireless way to deliver PPM, we can start controlling just about
any micro-controller with time tested, proven, low latency, highly
redundant, highly interference resistant, totally brainless,
off-the-shelf 2.4GHz hobby transmitters.<br>
<br>In other words, Radio Controlled robots just got a whole lot easier, cheaper, and more reliable.<br>
