RE: Sites for gas setup advice.
I am not as familiar with the other setup you're asking about, but here's a possible scenario: Fromeco Wolverine switch(battshare dual switch, highly regarded) with 2 smaller LiFe packs. [link=http://www.fromeco.org/products/04frcwo-430b/]Wolverine[/link] One side of switch/pack to rx; second side of switch/pack to ignition power lead. Regular optikill from rx to ignition. There are many arguments over possible interference of the various setups, but the TechAero has been acknowledged to be fairly safe here, and I've had no issues with the RcEXL BEC kill I've been using either...
