Do you have to buy an IBEC at all?
I have done range checks with no IBEC, DSM2 equipment passed the ground range checks, but I have not been brave enough to fly anything set up this way, I did add a large rectifier diode in line for the ignition module power, just for dropping the voltage a little.
I fly with the Wike RC IBEC, I love those things!
