RE: Sites for gas setup advice.
Sounds good to me. Simple but effective. I do like a switch between the IBEC and Rx so the Rx can be turned on seperately without powering the ignition.
There is one thing you need not to forget. No matter which way you end up with when useing LiFe batteries you need to do a timed flight, recharge the batteries and use the amount of mah replaced to estimate your total flight time available from your battery. LiFe batteries can not be measured like we do the others for available usage left.
