0 LiFe battery in a 4x2x2 battery compartment

 Somebody on RCGroups was asking about how LiFe batteries fit into receivers with a 4x2x2 battery compartment, similar to what's on a Turnigy 9x.  Here's some pictures of how it fits (summary: just right!).  There's no stress on the battery compartment cover when snapping it on, and just enough room for the wires.  Use the power connector that looks like a servo connector.

It fits nicely in this configuration, but the 9x power connector is blocked.  This may or may not affect you depending on your receiver's connector configuration.

0 3.3V PSU Update

I've configured the PSU I got a while back.  This is needed for the  5.8GHz video transmitter from Range Video.

It was pretty straightforward to assemble.  I put a JST connector on the input and output, desoldered the 12V pad, and soldered the 3.3V pad.  I wrapped the whole thing in a 3/4'' shrinktube, but a 1/2'' would have been better.

I'm not sure what the signal line is for.

Ordered this from hobbyic.com and stashing the docs, such as they are, here.  They note: "Do not power 1W video transmitter"
