Sling tsi or rv10
Mojogrip did a comparison between the two planes, ( check it out on YouTube)when I saw it I thought it was like comparing apples to oranges. The two planes are simply different in so many ways. The claim of the two being the same at higher altitudes, I don’t believe. I have yet to go for a flight, but one day I’ll go.
Vans and TAF are both great folks, Jean at Torrance, the chief test pilot and demonstrator is a fantastic person with so much knowledge of the plane. Make sure to do that demo flight, and talk to him at Osh; but keep in mind the kits come from South Africa, shipped to Torrance and is than shipped to each customer. We are talking months from order to delivery, Vans is in Oregon and if your missing a part or need a replacement it’s far less expensive and time turnaround.
I will end with this, the sling tsi is a fantastic plane but if you want performance the RV-10 is the plane, the sling tsi is easier to build, as it’s all pop rivets versus rivets for the RV and hence can be built faster than the RV. And this is important, the plans for the sling are lacking in so many ways. If your experienced it’s easier to get through, but it’s nothing close to the instructions and detail Vans has mastered in their manuals.
