Thanks for the link. Couple of things not clear in my mind; it seems the whole SS system is enclosed in one Tx and 2 (or 4 for that matter) Rx's so fine. As it doesn't look like it operates on 2 different freqencies (be it simmultaneoulsy like the ACT system or by switching from one freqency to another like the Emcotec DPSI-TWIN) what is exactely the added value of this system ? Do I understand well that each SS TX will only emit once it finds a free frequency and thus will not let anybody interfere with you if you are using a channel already ? So the system would be "other's users" safe but what does the system provide in case of an interference with "something" else than a SS R/C user ? There are plenty of radio noise out there, so is this SS system interference proof like the ACT is or no ?

Thanks
