EFM is being worked on, Wags doesn't say it's coming anytime soon.
Personally i already have the C-101 and the Hawk, waiting on both for the AFM/EFM.
I was considering buying the Mirage right away because i thought it would had the EFM right away as well, considering that the price was also a little higher than the usual modules.
But if this is the case, i think i will wait a little more =/
