MICROBEAST / MICROBEAST PLUS with single SPEKTRUM remote satellite on large helis

Why is using a single SPEKTRUM remote satellite only recommended for helis equal or smaller than 450 size?

We say it is not safe to use a single remote satellite on anything bigger than TRex 450 size as the chassis on larger helis may hide the satellite in different flight situations. So you will loose direct sight between TX and RX more easily on larger helis. Additionally with large helis you fly further away than with small helis, so this doubles the risk of loosing the RF link when the satelite antenna is hidden. Using an EU Version of the SPEKTRUM TX even more it is very likely the RF link may get disturbed in such situations as these radios do not have so much RF power output. If using an US version of the SPEKTRUM radio with 300mW output power this can be different though. But also here we can't give a general rule, as the quality of RF link depends on many other factors like such mentioned above (Where is the satellite placed? Is direct sight to the TX in any flight condition guaranteed? How far do you fly away? Are there obstacles in your flying field like tress or houses? ...). So it's hard to give a definitive limit and we only recommend to use this setup on small helis as this can be considered as safe application.
