Is it me being a grumpy old rotor head !! Why cannot engineers or designers actually make windscreen wipers for a Heli that work!!! Mind you having done some time (penance) on fixed wing they were not much better. So far I have seen the ones which clear about two inches in front of your face ( if your at cruise speed) and the ones which do a spastic dance all over the place ? anyone got a Helicopter with a good set of wipers that work ? when you need them in the hover!!
