"@Jose, you can use any firmware you want but with ULRS firmware you get RC + Bi-directional Telemetry. For video downlink, you need to use a video transmitter.  For detail, you my have a look at my post @RCGroups"

"Most of the RF Power MOSFET's of different manufacturers of same package (PW-X) used in RFM23BP, are rated 10-12V and have maximum of 4Watt output.  So it is not recommended to give more than 10V to the RF power…"

The most powerful RC + Telemetry system on the market "Ultimate LRS 2000mW, 433MHz"

Posted on February 5, 2016 at 8:00pm 21 Comments

I have a great news for the RC community that you can DIY the most powerful RC + Telemetry system on the market "ULRS 2000mW" using OrangeRX 433MHz 1W module and my 2W power mode. You need to have a magnifying lens and a small tip knife to do this mod. My greatest gratitude to FlipFlap…

XBee Pro 50mW RPSMA - Series 2 (ZigBee Mesh) - Sparkfun part: sku: WRL-10419, can not be used for Two-Way telemetry

Posted on May 10, 2012 at 6:00pm 27 Comments

XBee Pro 50mW RPSMA - Series 2 (ZigBee Mesh) - Sparkfun part: sku: WRL-10419, can not be used for Two-Way telemetry.

If you are looking for two way telemetry using a pair of this module “XBee XBP24BZ7”, then better do not buy it at all, I purchased one pair and suggesting, based on my findings.

For transparent serial communication between the airplane…
