EDIT (18th January 2023): IMORTANT PSA -> For anyone who has one of either the RadioMaster Ranger Micro or Nano modules (not the 2W flagship OLED module), please be sure to read the PSA that has been posted in another thread HERE.


RadioMaster have just released (for pre-order) a new ExpressLRS module which is capable of outputting 2W of power. From the factory it comes marketed as and locked to 1W for legal reasons but with a built in "hack" you can unlock it for 2W (see Wezley Varty's video after the product images in this post for how to do that). Orders will start shipping in December 2022.

EDIT: Due to Wezley Varty being investigated by CASA (see another post HERE), he's unfortunately taken down most of his videos including the one showing how to perform the 2W hack. To apply the hack you need access the web interface of the module by connecting to http://10.0.0.1/hardware.html. You then need to set High Power to 2000mw, Max Power to 2000mw, and set the last zero of Level Values to 2.

As well as the full size module with the OLED display on it, there are also smaller Micro and Nano versions available with no OLED display.

Any related videos are all linked to at the end of this post.

Description:

The RadioMaster Ranger is the pinnacle of ExpressLRS module design. Built not only to look great but to last with its rugged CNC machined aluminum case that aids the high-efficiency cooling system as a heat sink. The Ranger is up to any task and provides all the power and functionality you need.

Featuring an OLED display, a directional menu key, and two assignable shortcut keys the Ranger can be adjusted on the fly and personalized to your needs.

The Ranger includes a T Antenna for general use and a RadioMaster Moxon antenna for long-range directional applications. A micro module and nano module adapter are included to ensure the Ranger is compatible with most radios on the market today. A cable has also been included for use with Futaba radios that are CRSF capable.

Except for the Ranger, we also provide the Ranger Micro and Ranger Nano for your choice.

Oscar's review of the new RadioMaster Ranger 2.4GHz ExpressLRS module line-up is now also published at the link below...

So I just saw an ad on this full size ranger and I am contemplating leaving crossfire behind.

My questions are: what’s the range on the micro module vs full sized module? And what’s the price on the receivers? I see the t antennas can be smaller. So would I want the 900 or 2.4 module?

  I’d suggest using 2.4 because it’ll give more range at lower power settings.
 
  This video will explain better than I can.

 
  

I was always under the impression that lower frequencies cut through things better. That's why they use ELF for communicating with submarines.

Yeah I’m pretty sure the 900mhz is less packets more penetration and range by physics. But the 2.4ghz is supposed to have 30km range and the likely hood of going anywhere near that is slim to none for myself.

Yes, 100% correct. This is just on the carrier freq though. What I mean is that RF has so many things going on with multiphase, multiplexing and other attributes that the higher frequencies use of greater bandwidth allows them to bend some traditional rules with physics of RF frequencies. That's why 2.4Ghz is so popular, it's got the smaller form factor and all the RF tech behind it.

Unfortunately Wezley had to take down all his videos that featured him doing any long range flying after getting investigated and fined by CASA. Details about that are in the thread linked to below...

Here is a telemetry log from a "hypothetical" 100km flight showing LQ, SNR, and TX power. The arrow is pointing to a spot about 80km out where dynamic power dropped to 100mW for some time. The LQ then drops due to interference from a hypothetical town, and TX power increases to try to maintain maximum LQ. Hypothetically.
