| Subject: | Re: reverse prop rotation at shut down |
Dick,
I know a guy who has been flying a Kolb Slingshot w/ 912UL for a long time. For
several years he complained about what he called a "Rum Rum Rum" sound that he
could never cure. Sort of like the harmonics sound you get with a twin engine
recip airplane when the two engines are not quite in synch. Or tuning a guitar
with a tuning fork and the guitar is not quite in tune. He did everything everyone
suggested to no avail. Finally, he sent his gearbox to Lockwood (I think)
and it took a changing of the gear set to rid it of that sound. My memory
of the details could be off.
He may be on this Rotax List, if not, I know he is on the Kolb Matronics list.
It might be worth contacting him if the "vibration at cruise" you friend is having
is similar to what he had. His name is Ted Cowan.
