Dave Anders 244MPH RV-4

[pierre smith]

I recently read where California dentist Dave Anders has a CAFE record that beat an HR11 by a bunch!! Do any of you guys know of the mods he did and could you detail them? I'd like to incorporate some of them into my 6A.
Thanks, Pierre Smith

Every time that I see his airplane it has something different. I have photographed it at various stages through its life. But I have not seen it for a couple of years now. He has put the sheared wingtips on, the turtledeck fuselage mod, and a carbon fiber cowl with round inlets and (I'm pretty sure) a plenum for engine cooling. I am sure he has many other mods too. Last rumor I heard was that he had made the trailing edges of some controls with the RV-9 style double flush riveting. I am sure others that are more familiar with the airplane could tell us more.

Where can I find a link to the turtledeck mod? Our fuselage is arriving in a week or two and if it looks good, I might like to consider it.

Here's a link to the only site I could find on the topic.

This page has an RV-4 (white/green) with a turtledeck. Click on the "Pictures" link on the Left.

I think this RV-4 is homed in Bakersfield CA. But don't quote me.

There is a story of his mods on the net somewhere, I have read through it and it is very intertesting. This guy even lost weight, just to go faster. I will try to remember where I found it, which was by accident. It's out there somewhere.

Cheers, Pete

Correy, I moved this site. http://fastback-4.wheelsup.org

Unfortunately, I have little info on Dave Anders plane. I was reading this post hoping I could make my IO-320 fastback rv-4 burn a significant amount less fuel in cruise vs. stock. 20% is my mark, that's 6gph @ 140 KTAS or 7gph@160 KTAS. I suspect Dave's mods are a step in that direction.

Among other things, that airplane has:

Aerodynamic Mod's:

- Lamb wheels and tires and correspondingly smaller pressure recovery (Sam James?) wheel pants.
- Wide chord gear leg fairings.
- Circular cooling air inlets.
- Cooling plenum
- Fairings on virtually every drag producing item such as aileron hinges, fuel drains, etc.
- Fastback modification.
- Tailwheel steering chains removed for speed runs. Also, stock tailwheel replaced with tiny little wheel from a roller skate.

Engine Mod's:

- Severely tweaked O-360 running at 2,900-3,000 RPM. Prop to match.

There is a PDF file on the SacRvators web site with information on the mods from a talk Dave Anders gave at a meeting. here is a link
