I'm in the process of building my first nitro (RC8B3.1) and I have a question regarding receiver batteries.
I'm planning on running LiFe batteries, and I have a few brand new ones that I misbought a few months ago, but they are only 1450 mah.

How much runtime am I looking at with a 1450mah receiver pack? I don't mind changing out packs throughout the day, but I need them to last at least 45 minutes + warm up, so pretty much an hour straight. Would this be doable?
