Here.. from all the reasearch i have done for the eco.. since the eco has the machanical mixer thing.. u only need 4-5 channel to work for cp...(not sure if it 5 or more... or 4-5... but arround there...no special radio is need for this eco.. as you know.. when they sell u package... most of the stuff come with it suck...

I would recamend..

1. Futaba gy-240
2. Brushlless motor with brushless esc.. and u can usually get this for 150 both.... believe it.. u will upgrade anyway.. why spend money on the **** motor now and throw it away later..
3. a simple radio...

Well.... but sinc said money is not an issue to you... then you can waste it all you want.. but to me... money is an issue.. but good quality stuff that can satisfy u and don't regret later on is a bigger issue
