Sorry Storm. Didn't answer that question, because I don't know. It's also *not* an easy question to answer, and may not be answerable with just the info you have.
The motor/EDF you picked is strongly lacking in specs. While they give a torque and speed at 4.8v, that's the very top of 1S battery(probably not what you'll use), and doesn't tell anything about what current it will draw at 4.8, nor what the max current/voltages it will tolerate.
To then size the motor to the battery (ignoring mAh capacity for now) you need to know
- rough final weight of the airplane
- maximum thrust for a for each suggested cell rating (you don't have and usualy won't)
- maximum current draw at each suggested cell rating (you don't have almost always will)
most people cheat on the second one by multiplying the voltage by the maximum current to get watts, then using the rule of thumb W/lb of aircraft. Depending on the style of flying you want this RoT number changes, but 100W/lb should give you a fair balance of flying, and set your target for maximum weight.
Subtract out the weights for the things you know (motor, rx, servos) and you have the remainder left for the things you don't (airframe, battery). if you've got an idea for your airframe weight, you should know how much weight you have left for your battery for 100W/lb.
On the duration side, this is a difficult balance of adding more weight vs. adding more capacity. more weight means higher throttle setting, and shorter flights. more capacity means you can run the throttle longer at a given setting. this is coupled together by motor efficiency, which is something that is never speced. if your motor is still running efficiently, flight time can increase with added capacity/weight. if it's not, added capacity and weight will actually reduce your flight time.
To calculate *minimum* duration, take your selected battery capacity, then divide the maximum current draw. you should get decimal hours -- will probably land in the 3-10 min range. less is a bad fit, more is hard to do. keep in mind this is a full throttle, the whole flight -- we put wings on these planes so they don't have to run full throttle.
Looks like a nasty mess of things to calculate, doesn't it? It's why most people follow other's plans for sizing things, and either tweaking in ways they understand or trying things out with parts on hand.
Don't let this discourage you, but you might want to take an easier step for your first scratch build.
*My recommendation to you* either:
- if you haven't bought this EDF *and* you can't find the specs for it, find another one. you won't know if you can use it until you've bought and tested it -- rarely a good deal. Contact LT -- they may be able to scrounge up the specs. If so, then run the numbers above. Otherwise, start looking at other EDF setups where the info is available
or
- Look at plans others have published and see their recommended setups. Most will publish some sizing info and suggest the battery that worked for them. By all means pick a plan you like, but choose one with plenty of info to build on.
