ElyQ has released their new Voltage Regulators to the public, and are available over the pond currently through Fast Lad Performance, and Midland Helicopters in the United Kingdom. You can pre order your regulator at Fast Lad Here.
It is compatible with Ni-Cd, Ni-Mh, Li-Po, Li-Io batterys, and has a selectable output for the desired servos plugged into the regulator of 5V,6V, 7.2V, or by pass mode. Anything plugged into the regulator will receive the voltage the user sets, everything else thats plugged into the receiver will receive 5V. It weighs around 20g, and is roughly the size of a AR9000 receiver.
looks good. seen one in action. holds up real well and can be used in many different setups.
