stall warning
Got my RV=7 QB a while back and noticed it came with a stall warning system which requires some modifications on the wing. My RV-6 has done great for years without a stall warning system so I'm wondering if I actually want to install it. Is there something I'm missing?

I'm in the "It cant hurt" camp.

Vans is serious about getting people to install and use the device.
I had the same feeling about it and had about decided to go without it until I noticed the wing skin is punched for it. It took all of 5 minutes to complete the prep work to get the bracket installed. It may take some time to get it wire and calibrated, but it is going in.

I went the opposite route and closed up the pre-punched holes. That and riveting up the access cover means more work for those QBers who don't use the system, but I guess it saves time for more people, those who do install it.
I'm going to use AOA for stall warning instead.

They must be. Still, I would have liked to have had the choice of not having the holes pre-punched in the leading edge. Maybe instead of pre-punching the holes, provide a template to use to cut/drill them. If you go with an AOA system, isn't the stall warning redundant?

I believe that in one recent year about 24% of the RV fatalities were due to stall and/or spin situations. Better to have it (or AOA type system) and never need it than the other way around.

I've flown my Cessna 180 some many years that I'm accustomed to the stall warning sound. So I bought the stall warning kit and will install it on my RV-3B.
If you think about it, it's a single-point AOA indicator.

It's amazing how many good pilots stall or spin in. It takes about an hour total to hook up. It's your plane so it's your choice.

IMHO, it certainly can't hurt to have it. Since it will be indicating an imminent stall condition, react accordingly. Of coures, I'm biased, since I've never flown a plane that didn't have stall warning indicator!
