You’re right. CubCrafters really surprised me this year throwing a 916 iS on a Carbon Cub. I never thought I’d see the day!

VANS RV-4 915 iS. “How brilliant is this Van's RV-4 built to meet the German 600kg UL requirements, powered by a Rotax 915iS? The RV-4/600R has been created by Robert Haag, who runs PlaneWorx.de. Cruise is 160kts (85% @9,000ft) with a 1,800fpm climb rate.”...

Lightning fast and efficient. This is the definition of optimizing form drag.

There are actually several manufacturers using the 915 in faster designs. Take a look at the Blackwing 635RG and the Risen. Those are two of the most efficient airplanes that I know of hitting 185 knots on 6GPH with the 915. Fixed pitch works fine as well but makes more sense on an aircraft...

I was hoping for electric retractable slats and double slotted flaps to really push the envelope forward but oh well. The design is growing on me but I really don’t like the looks of the stubby nose when viewed from the side. A PBS TP100 would fix that nicely. :)

Tecnam P2008. Not the best visibility as the support structure will block your view out the left or right window but holy cow there’s a ton of leg room with the adjustable seats. My Dad is 6’2” with very long legs and he had tons of legroom.

VL3 is quite a different animal being all composite but BRM just dropped photos of their turbine Bristell utilizing the same Turbotech engine.

You can already buy a VL3 as an SLSA, it’ll just have to be fixed gear and propeller. But you can still get respectable speeds with the 915 fixed pitch propeller combination as Bristell has already shown hitting 145 knots true at altitude and still staying within ASTM consensus standards.

The two turbines installed in the Velocity are PBS. 35GPH between the two engines. Twin Turbotech’s on a smaller platform could yield 240HP at 18GPH.

Rotax 915 installed is 200 pounds on average.

Haha man you’re hard to impress, if you want efficiency you have to add weight via the heat exchanger. I’d say its a great tradeoff as you’re still looking at 40 pounds less installed vs the 915. Vaporware means no sign of the actual product. These will be shown at AERO in ten days with...

Every time I post excited about a new product or development it’s either lame because it’s too new or I’m being paid to say these things haha. In aviation three positives and one constructive comment would go a long ways. Peace out y’all.

Well you should be impressed because small turbine design won’t get any better than this. That’s the PBS TP100 until Turbotech releases a larger version. $150K FADEC 241SHP and weighs 157 pounds installed.

This small turboprop has the best shot no question. Check out the link I shared earlier starting on page 64 to learn more about the company’s origins.

Yes, no one has until now hence this thread. It’s not marketing hype with 6 months to develop the engine installation and with 20 hours in 8 days I’d say they have a pretty good idea it’s going to be popular. Yes it will be slower than the 915, but at a fuel burn close to Rotax what else more...

First of all, the engine on the RV-10 turboprop was called the PBS TP100 and BPS is very much alive. Data I’ve seen that includes all components needed to run the Turbotech TP-R90 engine show the weight at 163 pounds, so about the same as a 914 turbo or 912 iS with a max of 135HP. The...

I saw a price tag of $50K floating around for the TP-R90 but I’d guess it’s more like $70K now. But with a 3000 hour TBO that’s almost 3X as long as the $41K 915 and at a close fuel burn.

Yes most people is the keyword here, hence my creating this thread. If I had the money now I’d be ready to buy it ASAP.

Haha y’all are funny, you can buy the Experimental Exhibition 915 VL3 right now and fly it in the US. There are already two here and flying. https://youtu.be/3opHsGsI1j0 120HP at less than 9.0GPH is the official spec, which is amazing! I can’t wait to see it in person. I’d also like to see this...

Anybody else excited about this? The Turbotech TP-R90 seems very promising! https://www.fliegermagazin.de/wp-content/uploads/2022/04/turbine-boden-1455x970.jpg https://generalaviationnews.com/2022/04/14/turbine-teaser/
