There have been many threads on this so I will be breif as I am sure there are going to be lots of long replies here.


My setup and some reasons why.

2 4000 MAH Lipos, Lipos will deliver more current thus less voltage fluxuation under load.

2 Fromeco adjustable regs set to 6.5V, These are built very well and have a huge heatsink very easy to adjust.

1 Smart Fly Batt Share, This will balance the batteries and keeps one regulator from becoming the domiat power conduit. My batteries are never more than .01V different after 6 flights.

1 Smart Fly Power Expander. Provides a robust power buss, allows me to set regs to 6.5V that the servos get but still regulates RX power to 5V. Filters the power to RX so if the servo leads pick up any RF it dosen't get to the RX.

1 RX, Actual receiver failure is very rare. There are a great many things that are put into the catagory of RX failure. Crystal popping out, using the RX as a 20 amp buss, not properly mounting, no service loops on wires. Stuff that can be prevented thus is not the root cause of a RX going south.

2 JR charge switches, I have been using these on every gian scale airplane with zero failures, They handle the power day in and day out.


There are going to be lots of guys saying that my setup is too complex, has a single point of failure ( RX )and adds unnessesary weigh. Well.........bottom line is that it works and works well. Can't argue with success.
