u need to master keyboard+mouse combo...if u turn using only mouse sure slow one....heres one good way to train to be GODLIKE when using keyboard+mouse for chopper; dl bf1942, install desert combat mod (if u hv bf2 alrdy installed, then dl desert conflict mod)...if u master the chopper then u will hv no problem with bc2 AND most likely bf3, evading those tracers, rpgs and at4 will be a snap.
