Thank you for the replies. This set up I am using is not for stunt. I testing the arrowwind ef-1 motor which is a high rpm pylon racing motor . prop is 8x8 thin electric battery is 2200 4s 30 c speed control 60 amp and I am running it with a transmitter for throttle on a gold ber cosmic wind. It draws 48 amps with the trhottle at 80% rpm 13,800 i ran it for less than a minute maybe a minute and battery went down to 36% about 3.8 volts so I did not hurt the battery or the esc or the motor. I am only going to fly level for not very many laps I assume I would need to go to a 3200 mah battery but it is way heavier. i want the plane to go fast for a few laps and then land. I think the 3200 battery is 4 0zs heavier. I dont know if that is a good idea for the weight. I could recheck the stats with throttle at halfway to see what it does? I was hoping to get maybe 10 or 15 laps?
Here's something to understand. C rating is achieved by increasing the size of the internal conductors and the physical chemistry. A battery having a total amount of electrolyte, anode and cathode are capable of a specific amount of energy delivery. Watt x seconds or Watt hours. For a given weight you can parse that out in many ways depending on the internal conductors. Often times you'll see the same cell in two different batteries with two different capacity and C ratings. When you take them and do the energy calculation you'll see they have the same Watt second capacity. What this means is that you will more than likely have to increase the battery size. No way around it. What you need to determine is how much battery you need in terms of Watt Hours. To do this you need to determine the power required on your next test. The current is only half the equation. It only tells you if the wires are gonna get hot including the ones inside the battery.
So you are trying to achieve a run of a given amount energy expenditure. You can calculate your Watt usage and time of flight to determine the energy capacity you need in Watt Seconds. Then from that you can determine how much storage you need and the C rating required. The specific energy of LiPo batteries very from 100 Wh/kg to 265 Wh/kg. Not knowing how long a lap is it's hard to say how big the battery must be.
So static power for that prop running 14 k is about 0.9 Hp which is 671 Watts. In flight at 100 MPH that power is going to drop down to 0.54 Hp and 402 Watts. Lets say the laps will take 5 minutes
and the energy it takes to get up to speed is equivalent to one minute operation 6 minutes total or 0.1 hours. This means you need a minimum of 402 W x 0.1 hr = 40.2 Watt hours. Your battery and motor are matched for the 4s battery? It's important as the efficiency of the system will bite your effort if they aren't. Given that W= I x V and then current rating for you battery will be determined Icap = Whr / V. Since the previous calculation is solely what is required for the flight a 20% - 30% margin should to be added resulting in 1.2 x 40.2 = 48.2 W*hr. Then the capacity Icap = 48.2 Whr / 14.8 V = 3.2 AH. Looks to me like you're gonna need that bigger battery.
Here's a useful data link to the 8 x 8 propeller in order to do some analysis yourself.
