The aircraft has a total of 150 hours. Today two of us made the first flights since purchase. All went well until we got up to about 125 IAS and encountered some light turbulence. At that point we started getting a low frequency, high amplitude flutter in the elevator. This lasted for 3-4 seconds. Each time we hit a thermal it would happen again. It does not occure below 90 IAS. This bird has "feathers" on the underside of the horizontal stabilizer. Could thesecause this condition? Has anyone encountered or heard of some one that has? Any info would be appreciated. We suspect an out of balance elevator. Thanks in advance, Ralph Lerch lerch268@bellsouth.net cell 828-266-2064 ________________________________ Message 2 _____________________________________ Time: 09:18:56 PM PST US Subject: Lightning-List: Re: 2010 Arion Lightning for sale From: "ple190" Interesting discussion about props and speeds, keep the numbers coming !! I am still testing my Lightning and with a WC62FK58 I'm only getting about 120kias at 2900rpm at low level on a std day which is a little less than I had expected now that I have the wheel fairings on. Has there been any know issues with these props and how can you check the pitch ? Also dose anyone know if these props are balanced at the factory ? I am using the supplied composite spinner and i'm getting some vibration through the rudder pedals especially at 2700-2800rpm. Looking at getting a dynamic balance :? Any other tips for squeesing some more kts out appreciated!
