If you plan to run the motors on straight 5s battery voltage then you are going to be way down on power using a 420Kv motor. I'd estimate about 350W per motor, 700W total... Not enough to get a model...

I agree, if they used to balance quickly and now they take hours then i'd be concerned that something was amiss. Try flying them and see if it's the same story next time.
