I think going El-mod is a no brainer. There iare somany options with that setup in aint funny. plus you can use the 2.4 radio system and only need one radio for either tank. Just need seperate recievers. i would use 2 seperate recievers that are 2.4 though. that way you dont have to crack the tanks open everytime you want too use one or the other. Bilitz and the boys are comming out with some amazing things with the El-mod. i'm know i'm saving my pennies for one.
