I posted this in the Electric forum, but they do not seem to get the traffic that is over here, so maybe one of you guys knows that answer to my question.

So I am trying to learn all about electric flight. I have been flying glow for a little while and I want to get into electric park flyers.

I am looking at getting a Parkzone T-28 Trojan PNP and I am trying to figure out what battery to get to put in it. I am looking at a 2200mah 3S1P 11.1V 15C battery for it. Now, I know that to get the discharge amps you take 15*2.2, which is 33Amps. The ESC that comes with the T-28 is a 25Amp ESC. Does this mean that the battery could blow out the ESC or does that mean that it is a good battery for the plane?

If there is a chance of blowing the ESC with this battery, would the fix be replacing the ESC with a higher rated one? Or should I keep shopping for batteries?

Any help you can give I would appreciate, I am just trying to figure all this electric stuff out. Thank you.

The battery doesn't push the amps, the electric motor pulls the amps. You want a battery that is rated the same or higher than your motor and ESC or your power system will cut out at full throttle as the battery struggles to provide the juice that the motor and ESC are trying to pull.

The battery you described should work just fine. I run 1800mAh 15c's and 2200mAh 15c's in my T-28. Like biged point out, it is the motor and prop combo that will determine how much current is pulled out of the battery.

Just make sure that the battery you get fits snug in the plane. It has a pocket that the battery slides into. Basically friction holds the battery in place. Having the battery in this spot usually sets the CG right on the money.

You'll love the T-28. I wouldn't necessarily recommend it as a first plane but for a second plane or even a 100th plane, it is great.

That is exactly what I wanted to know. Thanks guys!

The way it works is you get a motor that has the ability to carry around the weight of the plane you are going to fly with, depending on the type of flying you wish to do. So, there will be a 'wattage' rating for a weight category, basic flight, sport flight, all out 3D flight, for instance. Then, you match the three (motor, ESC, battery) to the numbers you select. It's always good to select a pair (motor/esc that will be slightly more than you need, then match the battery capacity and delivery capabilities to your motor and esc combination. That should get you pretty good performance.

Basically: The usual rule-of-thumb for "normal-sized" (read: .10 to .60-sized aircraft) model aircraft is 75 watts per pound for trainer-type handling, 100 watts per pound for aerobatics, and 150 watts per pound for 3D.

For watts: multiply voltage times current. Power = Voltage X Current 3 Cell = 11.1 volts. So, 11.1(volts) X 25(amps) = 277.5 Watts. (just an example.. do yours yourself to see what you come up with).

There is a web site that can give you all that information and you can select from there. I don't have it right at hand, but a google search for something on the order of what you are looking for (motor and ESC for instance) will eventually find what you need.

However, based on what you said, though, this sounds like a pretty good combination for you.
