As i posted last weekend my brand new regulator wasn't working to support the 5v needed for the gyro, under load the 4.38v it was producing wasn't enough for an 8900g 
(and interesting to find out on a Maiden)
So, knowing a little to be dangerous about electronics i determined that the method used to drop to 5v from the 7.2 i'm running is nothing more than a couple of resistors and a 3-terminal regulator (i'm not saying theres anything wrong with this method because theres not).
But i decided to build my own.
I had lying around a 8a Flightech regulator, it had had all its wires cut down to a minimum as it has far too many inputs and outputs as standard. However it does have adjustable voltage from 4.8v upto 6.5 so i'll future proof any gyro\servo combo that goes in, unless its proper HV.
So, using a voltmeter i set the output to 5V fixed. Then i set about re-soldering the wires inside. As i'm using a JR servo i used a JR servo ext lead. I soldered the male input wire from the rx to the regulator and the output from the regulator to a female connector. The regulator sits inbetween the Receiver and the JR7000T amplifier. It drops the voltage down outside the receiver.
One really important step is the yellow "data" lead is just looped internally and bypassed by the regulator.
So there you have it, an 8A regulator for the Gyro.
I know its probably overkill but i enjoyed making it none the less.
