I am having trouble knowing which planes are better then others. Like which ones are better at turning, and which ones are better at climbing. So that I know what to do when I get into a dog fight. Is there any way I can look at a list of planes with there strengths and weaknesses? Or is there an easy way to find this stuff out?
There is nice program called "Il-2 Compare" which lists all the planes in the game with a bunch of performance figures. It's important to note that raw numbers like "top speed" and "best turn rate" should be taken with a grain of salt.
For instance, the P-51 has the same Merlin engine as the Spitfire and is 1.5 times as heavy but still manages to have a faster top speed. However, don't expect it to accelerate like a Spitfire or to pull energy-sapping maneuvers and still be able to survive a fight. If a Spit and P-51 start co-alt and fairly close together traveling at 200 mph, the Spit will easily catch the Mustang....something to consider before yelling "It's porked!".
You can find Il-2 Compare (along with the 4.11 update) here:
The figures aren't wrong as such, they just don't tell the whole story. Taking the P-51 / Spitfire example above:
The have (roughly) the same power
The Spitfire weighs less, so it accelerates better in level flight at low speed
However the P-51 has less drag at high speed so it has a higher top speed and better acceleration at high speeds.
So you have to consider not only the figures, but also the situation.
Another hypothetical example, consider two aircraft A and B. A has a low top speed but good power to weight ratio and low wing loading. It can climb at 2500 feet per minute at best climb speed of 140mph and top speed 300mph.
Aircraft B best climb is 2100 feet per minute at 155mph and top speed 360mph.
At first glance it would appear that aircraft A can outclimb aircraft B, however at any speed over 300mph and less than top speed, aircraft B can both gain distance and altitude over aircraft A. At speeds down to not far over 200mph, aircraft B's rate of climb is higher than A's for the same speed. If aircraft B slows down to outclimb, A will be out of sight in very short order. If B tries to keep up, A will be able gain an altitude advantage as long as he doesn't slow down too much.
Similar comparisons apply to best turn, roll rates and so on. You need to consider not just the figures, but also the situation in which it is possible to achieve those figures, how long they can be sustained and techniques that may be available to the pilot of the "inferior" aircraft to overcome its apparent deficiency for just long enough to either get away or kill you.
