My RV-8 has the strakes as well. I don't know any different, but my airplane is capable of being three-pointed. My friends who've flown my airplane, as well as their own without the strakes have noted quite a difference in the flare.

Generally, aerodynamically, for everything you get, you often give up something else. Those strakes are small enough to not be a weight issue, but perhaps a slight speed loss? Clearly, if they assist in three-pointing, they help with higher AOA and slower speeds. How are they when you're tail-chasing your buddy at higher than landing speeds? Has anyone modified their upper intersection fairings in any way to work with the strakes?

If they were without a downside, everyone would have them.

When I was flying with Bruce Bohannon back in October, we accidentally figured out that the tiniest touch of power in the flare seems to break up these vortices. You get a smooth 3 point and no tail wiggle.

Thanks for posting this!

Mmm? Lots of drag in cruise?

Does anybody have another supplier for strakes, I called micraero and they told me they only sell the strakes as part of a kit that includes vortex generators for $395. I only want to try the strakes.

Default Roll Your Own Strakes?

Question: If I try to create a RV8 specific wing leading edge strakes, can I create from a mold of the leading edge? Is there any consideration if I plan to roll my own version? The strakes in the pictures don't follow the leading edge profile but I suppose there is a reason for that. Any online reference I should look into?

Thanks.

Unable to provide any advice on the creating your own, shape or placement - I'm sure the company that sells them tested the fluid mechanics to some degree for safety reasons. They also don't need to be the shape of the leading edge as it serves a different purpose.

I searched ebay for the part number and found these results - they seem to be similar to the ones on the RV-8. https://www.ebay.com/sch/i.html?_fro...trake&_sacat=0

The strakes came factory installed on the Cessna T303, would not take much effort to reproduce a set by tracing a paper template.
Bend a 90 on a piece of Aluminum and stretch the small edge to form the shape.
