I am going through this again due to the sheer frustration of not being able to fly this weekend again due to problems with my local field.
Again two questions[&o]
1) Can LiFe battries be used with electric motors? For eg, the GP Extra 330SC foamy recommends a 11.1V battery for outdoor flying. However, LiFe battries are only available in 6.6V. How then dou you use with that plane? Also what ESC to use?
2) Again a airplane selection. Though I am good at glow, electric I am new to. I can probably hover, waterfall, flat spin but everything else in 3D in need to learn. Should I go for Foamy (Such as GP Extra 330SC, GP UCD 3D EP or go for the XLC like Yak54 EP or Edge540 E-performance? The XLC s are a bit larger an I dont know how much space they will require to fly, considering the local ground is about half a football stadium

You can use lipo, life, lion, A-123, etc batteries to power your plane. Which ever battery type you decide to use
MAKE SURE YOUR CHARGER WILL HANDLE THAT TYPE OF BATTERY. These battery types have different max voltages per cell and over charging them will most likely damage the battery.
MOST intelligent chargers can handle these types of batteries.
As for the ESC - the ESC is used to regulate the amount of power (amps) to the motor, and should be based/sized according to the motor specifications (amps)
AND the number of cells (volts). Your LHS can provide specific amp/volt specs/ratings of the ESC based on the motor/prop/gearbox (if any) used and number and type of cells (volts).
I am not certain about LIFE batteries, however the various brands of ESC's I have used will all handle LiPo, Lion, and A-123 batteries. If you are using a separate BEC for your servos you
MAY need a voltage regulator in line with the BEC to insure that the servos do not get excessive voltage if you are not using LiPo, NiMh or NiCD batteries.
I would suggest a "foamie" for the plane. They are light weight, can handle a fair amount of abuse and are
USUALLY easy to repair using foam safe CA or epoxy.
