C ratings have nothing to do with runtime... WHoever told you to run 3s was an idiot... You should try 4-6s 5000mah for a 20 minute runtime(or at least close). For the price zippies are the best you can get and worth the wait if thats all you can afford.

If you have cash to burn go with anything with enerland cells. Enerland, Polyquest, flightpower, and rc-monster are all good brands.

Stay away from maxamps tho.
