When you are on map view - 0deg is north
When you look out the scope - 0deg is from the bow

also, i have tried your 90 degree angle TDC but im using real navigation and so things are not adding up to me or am i just completly stupid and dumbfounded...math isnt my strong point lol...at all lol like i beleive your speed in knots was 7 knots as he travelled 2700M or something...mine...well mine was way higher as i didnt really know where to measure to as i dont got map contacts either really so how would i know where to measure to get targets speed and such?

The fast90 tut is for use with map contacts on.
Instead of using the map - try finding the speed with the u-jagd
