Your not getting much for hits because you posted it in the wrong area. I would copy it to the air plane threads as those guys will help you quick. As far as your question i would look up what the capabilities of that esc and also how consistent the discharge is for the packs that you are using. some packs are inconsistent which needs to be considered. I always go bigger on the esc than necessary just to make sure i dont have issues with heat/fire/puffing but with the weight restrictions on planes i know that isn't always an option.
