KO receivers and questions

[qatmix]

Hi All

I have an Esprit Vantage 2 (not the type-r). I currently use the 40mhz 297f receivers in my cars but need another one to go in my new buggy.

The question I have is would a 302f one work well? or does that need to have the digital transmitter?

Also If I buy a 27mhz module for the KO, would it just work with my acoms receivers / crystals in my vintage cars? or would it need me to get the narrowband 27mhz receivers they make?

Cheers
