Keep in mind that 5-6 volt supply to the RCexl CDI is the sweet spot. Supplying the production SAP IBEC with a supply of 6 volts means the IBE will supply around 5.4-5.5 volts to the CDI at full revs.

CH said using more than a 4 sell pack is a waste of energy and the ignition will work fine to below 4v.
The Tech Aero designs IBE also drops voltage to the CDI (they all do BTW)
Isn't that the point of the voltage regulator in the circuit, to reduce the voltage below the 6 volt max threshold?
Low V-drop filter pots are designed in.
Opto-isolation, capacitors and or chokes filter noise.
The point is that Ed Alt the designer of the Syssa IBEC knows what he is doing. He has optimized voltage output and EMI-RFI filtering/shielding for a trouble free unit. Just drop in and play. FWIW2U
Ed Alt himself said the unit sold by Todd is only for use with 2.4ghz equipment, a new version with better filtering is in the works.
Each unit made by Wike is set up for a different input voltage range.
This switching unit from TI is almost ready recieve a signal to turn them on and off and shut off the regulator if the input voltage drops to below 4.5 volts which would save the receiver/servo voltage so you could land dead stick rather than loosing total control and only need the addition of a resistor, a few capacitors, servo leads, an led, some shrink wrap and possibly a pic:

Or a little overkill:

BTW,
Wike uses diodes to drop the voltage as previously stated.
