Yes, rudder is supposed to make diagonally opposite motors (which spin in the same direction) spin faster. Left rudder should make the CCW motors (M2 and M4) spin faster.

So your Tx is mode1 ?
Well, there is no problem in interchanging the aileron and rudder channels if it is comfortable for you.
Bu which is your radio ?

you meant aileron and rudder, ain't you Huh?
What you are trying to do is changing your transmitter to work as mode3 . But most programmable transmitters have built in mode settings, to chose different modes - if your Tx has such a function, you can avoid interchanging receiver connections Smiley

@VTOLKarthik, default PI values are enough for starting, after stabilizing your quad with transmitter expo, sub trims and trims, you can get to PI tuning , for the response you need Smiley

250 is way too high. What are the new values you set it to? This link will also help you tune the quad: http://oddcopter.com/2013/01/06/easy-diy-quadcopter-build-part-4-tuning/ The initial values given in this link should be OK. BTW, what are your self-level gains?

I think you should first try flying with self level on and then once you are used to it move on to flying in acro mode. Self level helped me a lot when I first started flying my quad and now I am confident flying with self level turned off. Set the PI gains to:
Roll/Pitch P-gain: 30 (This is pretty low, you could even start around 40-50)
Roll/Pitch P-limit: 100
Roll/Pitch I-gain: 0
Roll/Pitch I-limit: 20
 
Yaw P-gain: 50
Yaw P-limit: 20
Yaw I-gain: 0
Yaw I-limit: 10

Self level P Gain should be around 40-100 (max). Newer firmware versions have improved self level feature so an update may help your flight performance. just to check, you have loaded the correct motor configuration right?
