Waldopepperaxel, you probably hesitated between a 700mah and a 1300mah... is it a 2 cell or 3 cell? that also makes a huge difference... (11.1V nominal versus 7.4V)

the esc; if it's a castle creations you are good for the 12amps wot on 3 cells because it takes bursts of 15 with ease, and your loads won't stay at 12A for very long periods of time as airspeed increases.

If you got a 3 cell 700mah it might or might not work, packs have c ratings. If your pack is good for 15C you're allright (15c means you can discharge @ 15x the capacity rating of the pack. in other words if it has a 0.7A storage capacity you get 0.7Ax15c=10.5Ams continuous discharge rating. If it's a 10c lipo at 700mah you only get 7A continuous, a bit weak though they usually have margin for bursts... 10c 1300 would be fine but much too heavy for a flatout :/ So, basically if you run a 700mah 10c pack i suggest you prop no higher than an 8x4 and go easy on the throttle.

packs have 2 ratings, continuous and bursts. some go up to 20c continuous and 30c bursts. Doesn't your brand new pack have a lable with this information?
