So redid an old pending project, bought some stuff from quadkopters.com(great service)
got IMMENSE help from jaspreet and others here

Using my old Kk2.0 board with new LCD replacement.
NO THANKS TO RIBZ for making me feel cheated after not replacing the faulty board I purchased from him!

Will add new stuff to it-
1. variable CG landing legs
2.More tuning to be done.
3.Adding other cool stuff.
4.FPV later

Clean wiring, What Mr.Ribz says ?

" It doesnt say 'Sensor Not OK' so there is no problem with the board."

W-T-F

What can I do now ?

I've given up on my board. For next time, new people dealing with him, please let them know what happened with me.

Well, if there is no o/p from sensors, then it won't say sensors not ok !

Force that guy for a replacement - if he think this board is still fine.

i've tried. He is actually here on RCindia. Perhaps someone with more persuasive power can help me
