RE: Sr batteries x250??
I am trying to update a used and abused X250, but still haven't figured all the new brushless stuff yet.
From doing several searches on the web, almost everything I find is old (before 2007) and only talks about brushed stuff, or the older 9but at the time new) brushless items.
I tried going through hobby king for a replacement, and while cheap, got a headache trying to figure out prop adapters would fit and which ESC's came with which connectors vs. no connectors at all...
For now its put aside while I redo an Avistar (cut the wing in half and removed all the dihedral, tail dragger conversion, and more) and an old GP Patriot 40 ARF.
