FlySky FRM302 and FTR16S AFHDS3 receiver = 2.4GHz Long-Range radio system

ImmersionRC Ghost is the new long-range 2.4GHz radio system that is getting the most traction in the media in the last few days. However, IRC Ghost is not the first 2.4GHz SX1280/SX1281 LoRa based radio system that has hit the market. FlySky FRM302 TX module and FlySky FTR16S AFHDS3 receiver are available since May 2020, and underneath, they are the same technology as Ghost.

Today I will not go into the details of FlySky FRM302, only show you some pictures of it. And yes, the heatsink on the Power Amplifier and radio section is huge! This is because energy conversion on 2.4GHz is not very efficient, and a lot of energy is wasted as heat. After all, this module has 500mW max output and can produce a lot of heat in the process!

One thought to “FlySky FRM302 and FTR16S AFHDS3 receiver = 2.4GHz Long-Range radio system”

  1. As far as I could find it’s max power is 2W and unfortunately it’s only PPM or IBUS. No OpenTX with SBUS. That means a no no to me.
