Re: FR-Sky Dual frequency setup and redundancy

Post by Cliff Evans »

Frsky makes a redundancy bus system that utilizes two batteries and two receivers. There are two units RB10, https://www.t9hobbysport.com/frsky-redundancy-bus-10 and RB20 https://www.t9hobbysport.com/frsky-rb20-redundancy-bus. I use the RB10 in my 1/3 scale T21 and have been for the last three years. They have new system coming soon to replace these two systems. The RB30 https://www.frsky-rc.com/product/rb30/ and the RB40 https://www.frsky-rc.com/product/rb40/

With the Access system you can have up to three receivers bound to one model, each can have their own power supply. Only one will have a direct connection to the servos, the other two receivers are connected to the main one via Sbus which in the event of loss of signal even if the battery goes the servos are always connected to the other two receivers so redundancy is pretty good.


In the not too distant future, there is a new transmitter planned that has both 2.4 and 900mhz on board that can be used together to transmit to two separate frequencies simultaneously.
