It is easy to make and install while constructing the tank. I believe it can be easily retrofitted to an existing tank with minimal effort, but you will have to remove the flop tube from the 90 bulkhead elbow. Photos are posted on my website ExperimenalAero.com http://www.experimentalaero.com/flop_tube_anti_rotation.htm Paul ----- Original Message ----- From: rwtrwtau To: RV7and7A@yahoogroups.com Sent: Thursday, January 13, 2005 12:56 AM Subject: [RV7Yahoo] Re: Flop tube problems For those that are interested, I was told by Vans that flop tubes should be fitted with anti-rotation brackets as well. This makes sense to me but is not depicted on the drawings or described in the instructions. It will be fun installing them now... Another kind person pointed me to the Standard Aircraft Handbook, where the torque figures are in fact listed.

Selling my cherokee and the kit is next. I know, I know. But, I gotta do what I gotta do. My Harley is calling. RV-9A: QB fuselage, 95% complete wings, 70% complete empennage, fully primed, dual lights, brakes and steps, AOA installed in wing. Cost around $22,000 to buy equivalent new now, cost around $16,500 for all the parts to me. Will look for around $15,000. Curt Hoffman Cincinnati area contact at choffman9@cinci.rr.com
