There have been a number of discussions about this in the past few months, and at least one of Van's documents discusses it, too. Here is one of the VAF discussions.

Yes TAS
Bill - this has been addressed many times here on VAF and in Van’s docs. I’m sure someone will cite the exact references. But, yes VNE for the 7 is TAS, NOT indicated airspeed.

Rudder flutter
 Fourth owner, 20 year old Oregon built airplane, no builder logs. Hard to read builders mind, but our A&P thinks that builder failed to trim fuselage skin so that empennage could contact rear bulkhead. Photo shows three and four 1/4 inch spacers used to attach to fuselage. Need help uploading pictures. Recovery just requires slowing down. No visible damage. Oscillation felt in rudder pedals and yaw fishtailing.

To add a picture just select the paperclip icon on the top row of the message box, browse for the picture you want to load from your computer, select upload. That's it.
New feature here, I had the same problem at first.

It might be prudent to NOT fly that airplane again, until you figure this out. I’m trying to visualize the 3 & 4, 1/4” spacers and why/where they are attached. Structural deficiencies in this area is not to be ignored. Original RV4 & 6 elevator and rudder skins were .016 thick. Newer ones are .020.
