If you fly RC planes by FPV then the use of a UHF RC system to obtain greater range is an option many will consider and this review looks at the RMILEC system.
Here are the pro's and con's observed in part 1 of this review:
Pro's:
- easy to set up (binding, module installation etc)
- build quality (excluding the TX antenna) is good
- reasonably priced
Con's:
- transmitter antenna is poorly designed and built
- no output filtering means it is very "noisy" on 2nd, 3rd and even 4th harmonic frequencies which could well cause problems with video links on 1.2/1.3GHz
- transmitter module runs very very hot which could cause premature failure
- no obvious method for updating firmware
- the use of only 3 frequencies
From a technical perspective, this system has some significant issues but I will reserve my final judgement until after the flight tests. Stay tuned for part 2.
