no, im not bored, it was pretty much fun. i learned batch last thursday and i gotta say its fairly easy and you can do a lot of stuff with it.
and then... well when you calculate something it will return a rounded number...

full version
single engine calculation tool

i know its not great, but maybe it will help someone calculating the needed engine power or make searhing for a mp Server easier.

when you start the file, it will ask for a command. you can type:
mps: checks if mp-servers are on and lists them
mps-: lists mp Servers without checking if they are on. runs a Little faster.
x: (or start) will start simpleplanes.com and opens the files of simpleplanes
cls: clear log
col: Change color
cs: Show cheatsheet
shdwn: ask you to set a timer, and shuts down your Computer after the time is over. closing the batch file will not Abort this.
a: abourt shutdown (shdwn)
eng: engine power calculation tool.
enter the mass of your plane, the engine type you are using and the wanted Multiplier (can be used o make engine more efficient).
it will return the whole calculation and some other stuff.
valid engine types are j25, j50, j90, bfe150, bfe300, vtol.

as i have already said it was pretty much fun, i hope you will enjoy it too!
feel free to modify and think about learning batch, you can do so much cool stuff with it!

how to run:
save a empty file on your Desktop
name it SimplePlanes.bat
start it
