Vans RV-10 vs Sling TSi. Comparing two popular home build kit aircraft options. 

Ahhhh - good memories of me making my first "why I am building Sling".. Nice overview!

Nice job! I considered making a comparison video like this, but didn't want to get bogged down in arguments with RV owners in the comments. 😆 Bottom line, they're both fine airplanes, as you say. Here's a few points I might add, for anyone else deciding between these two planes: Build and cost: While it's true (or at least WAS true) that the basic Vans kit is cheaper, it takes more hours to complete. If one wanted to compare apples-to-apples, the Vans "quick build" kit takes the same number of build hours to complete as the Sling "slow build" kit. So, if you compared the Vans quick build kit price to the Sling slow build kit price, their cost advantage disappears. And for those going with build-assist, those extra hours the RV-10 build takes will translate into extra dollars. Plus, as you mentioned, the Sling kit is more complete. Once you buy popular third-party interior kits (seats, sidewall upholstery, center throttle quadrant, overhead, etc.) and other options that most RV-10 builders buy to modernize the look of their plane (wing tips, cowling, etc.), you're spending far more on the Vans. And finally, with their recent 30% increase of kit prices, there's no longer any way anyone can say an RV-10 will be cheaper, even without the third-party options. Performance: RV-10 owners will remind you that they can decrease their fuel burn down to 10 - 11gph by running LOP. That's true, but then their cruise speed will be more in the 155 KTAS range, pretty close to the Sling TSi at ECO power. Conversely, a Sling TSi pilot can run at max continuous power and cruise at 165 - 170 KTAS (in the high teens) while still burning only 10.5 - 11gph . So, pretty darn close in terms of cruise performance. Also, while the RV-10 shows a higher initial ROC on a SL standard day, the Sling TSi's turbo means we'll do better in hot & high conditions, and will retain our ROC better as we go up in altitude. So again, in real-world, pretty much a wash. At the end of the day, you'll end up with an awesome airplane whichever way you go. Happy building!

I'm curious to know the difference between the aluminum you speak of between the two and how you got this information. Mostly Kaiser 2024-T3 aluminum in both kit types. Why is one better than the other? Corrosion is usually an issue in bonding different types of material together. Such as aluminum against steel. It's not the quality of aluminum.

Lower quality aluminum???? They use mostly 2024-T3 with Alclad, which is a much higher quality aircraft aluminum than is used on some other manufactures' models -- and is far LESS likely to corrode without any additional protection. Where did you get your misinformation from?

After comparing the two aircraft, despite the higher initial cost, I'm purchasing the Sling TSI first!
