Barrie" Subject: Re: RV7-List: RV-7 engine/prop options I haven't read all of the posts on this but I wanted to comment on this thread. This is my experience with the good and bad and 100% honest. I have a RV7 with ECI IO 360, dual Pmag set up with Precision FI system. Nothing hopped up or fancy on the engine. My prop is the Whirlwind 200RV. I purchased mine from Whirlwind before they were sold to Titan aircraft. As has been noted, the 200 RV was designed for RV airframe. Specifically I cannot say what type of testing or research was done, but from the performance it clearly works. On initial flights I was getting significant surging with the prop. If the throttle was applied slowly there was no issues. If applied quickly there was a lag then the prop would grab. The best analogy I can give you, it was like driving a manual transmission car and after getting rolling you just suddenly let out the last little bit of clutch to get a little jolt. At 55 hours and on my last flight before breaking down for paint, a seal went out in the hub. I initially got a little oil on the windshield. After landing and shutting down I noticed oil pouring out of the front of the hub. I took the prop off and boxed it and sent to the new WW. Greg called me and let me know a seal was apparently installed improperly during the hub manufacture. He said the seal was most likely causing the surging. No coverups but an honest evaluation of the problem and the fix. The other known problem with the WW has been with the spinner backplate brackets. I to has this problem but this to was taken care of with minimal discomfort and down time. Now the performance. Another 7 is based at my airport with the same engine. His weighs probably 50lbs less. He has the Hartzell BA prop. At the same power settings my plane will run away from his. I had the prop dynamically balanced a couple of weeks ago and the balancer got it to 0.00. He said he has never got one perfect. He also noted the blades track better than anything he has seen. Another performance story. Robbie Attaway, (Attawayair.com) has a 6 with considerably worked ECI IO 360 with the ECI cold air sump and their FI system. He initially had a Hartzel BA on it. He wanted more speed and spent ton of money on an Aerocomposites prop. He did not get the performance he thought he would couple with a couple of structural issues so he returned it and ordered another Hartzel. The Hartzel lead time was 4-5 months. One of my neighbors has a WW 200RV for his plane as was not going to be using for a while. Robbie put it on his plane and using his words, "the airplane came to life." He said the plane is considerably faster and smoother. After only a few hours, he ordered a WW 200RV. Within a few weeks he had the prop and couldn't be happier. Many will continue to go with the Hartzel because it seems like "the standard." If you want a superior prop in performance and smoothness consider the WW. The company is great to work with. There availability and service is excellent. This is a big company that isn't going anywhere. Give them a look. Robbie will be happy to talk to you about his experiences.

I built an RV-7! 8^) You're talkin' about an RV-9 wing on the RV-7 list. Give Van's a call and I suspect they'll authorize use of a blind rivet there (I won't pretend I know which type they'll recommend). )_( Dan ----- Original Message ----- From: Smitty To: rv7-list@matronics.com Sent: Thursday, April 26, 2007 3:12 AM Subject: RV7-List: Flap Bracket Question I'm trying to rivet the top angle piece on to the flap bracket and rib and my offset rivet set and rivet gun won't fit between the ribs for the center flap bracket.
