Adding power adds weight every time, if you want to maintain the same flight duration.
Carrying that weight requires more power for minimum airspeed to maintain controlled flight. The increased minimum airspeed needed is directly related to weight. The power needed has a CUBIC relationship to the increased airspeed.
You have to have 8X power to double airspeed, before you get there you can easily be too heavy to fly.
The 4S Dynam 70mm fans are pretty decent. The 60 amp ESCs Dynam supplied previously were marginal for the fans. They work much better with Castle ESCs.
