Advanced Radio Systems Smart Bus?
 

Anybody using these products in there jet? Looking for user opinions specifically with spectrum DX 20 radio. Running out of Channels with my F-18 and looking for options for expansion. Thanks

Right now you'll be limited on how many channels can run at 2048 resolution with a 22ms latency on the DX20 with the 20 channel PowerSafe rx's. There is a new AS3X module for the PowerSafe rx's which along with gyro functions, allows for port mapping on the rx, forward programming and all 20 channels fully functional. We've been promised the thing for just over a year now and the folks at Horizon are just about swearing on a stack of Bibles that it'll be here next month.

I've got a DX20 and four 20 channel PoweSafe rx's just waiting..... lol

Here's the AS3X module;

Couple simple ways how to go around DX20 system limitations. The Emcotec DPSI 2018 can provide almost unlimited number of connected servos and accepts XBus, EXbus, SBus, UDI..... I use Jeti bus system.
