good to all,Pardon my English but I am Spanish......Need help..I want to put on my radio hitec agressor srx 40mhz a module spektrum ,,,But not where. model spm 1014 for futaba Is recommended?Or that I model applies??
spm 1004,1012??

Model 1014 Is the spektrum pro series system ( module and receiver) for futaba and Hitec.

Model 1004 Is the older system for the futaba and hitec radio both of these are compatable with the Hitec SRX radio.

the spektrum 1012 is the spektrum pro-system for the Airtronics M8/m11 which will not work. Hope this helps

I have an aggressor SRX with the 1004 in it

I have Hitec Lynx3D with SPM1014 no problems.
Relocated antenna to Lynx3D original antenna place. Still works
Go for SPM1014 !
