If one is different angle to other - that is definitely wrong.
The paddles are usually screwed onto flybar shaft ends ... When I fit mine - I always count the turns so I get both paddles on same amount and also same distance from head centre.
The angle of the paddle should be dead horizontal in line with main rotor blade holders ... at all throttle / pitch settings ...
Watch "Finless Bob" set-up videos on Youtube ... or do as I did ... download them to your PC and save for future reference.
You need a straight edge or best a pitch-gauge ... place on paddle .. by pressing down on OPPOSITE side flybar shaft you can lift shaft / paddle to then sight along to rotor holders. If it is anything but zero pitch / inline with holders .. then simply turn paddle while holding shaft ..
