[NSRCA-discussion] Going Electric - Battery Questions

That setup will work great. You wont be able to get through it more than once though. Thats just part of flying electric. 30c is more than enough. 20-25 will work also. Should use around 2500-3000mah per flight so you could get away with 4400mah packs or so.
