I have done a search through 'electrics' but cant find the answer
Basically i am looking to buy a 2nd hand Ko esprit 3 radio, i am looking to change the 40meg module to Spektrum 2.4
I have been on the Spektrum web site but nothing comes up under the heading 'surface modules'

Could someone tell me which module i would need to fit the esprit 3 please,if i do end up picking up a 2nd hand module too i dont want to pick up one suitable for aircraft etc
Thanks
