Ruh-roh.
Everyone who purchases an aircraft will be required to spend a 2 week period at a construction center to perform the close-outs on their aircraft in order to fulfill the 51% rule for construction of an experimental kit aircraft.
Double ruh-roh. I'm thinking the FAA is going to scotch this.
Almost certainly vaporware.
But to be fair, belt drive is a proven technology, as is water cooling.
300 KTAS on 300 HP while providing pressurization is not going to happen. Here's 250 KTAS on 400 HP.

At least they have their cost break down listed now. 176K just for parts but yet I get it complete (with my 2 weeks) for only 130K???

The interesting thing about that project is that it got me looking at getting a PPL. I'm getting signed up at the local college to get Ground School done this spring (company pays tuition there), and then start the flight training (simultaneously). Mrs. thequick is interested, mainly because she doesn't like long car trips, and the one she hates the most is the 12 hour ones between (essentially) KPAE and 2S6 the day before Thanksgiving.https://m.youtube.com/watch?v=Q1IeNwhsv8g
I knew that original canard wasn't going to cut it. Just too small. Haven't seen a spec update with a bigger, higher lift canard.
I joke about the thing but I honestly hope they succeed. This would actually be on my future aircraft list if they can pull it off. They're based right down the road from me so I'll be watching with interest.
Can't say the landing inspired confidence.

In fairness, that is an RC airplane with an undersized canard with full elevator, flown by someone on the ground with no flight deck perspective.Can't say the landing inspired confidence.
Everyone wants to **** on innovation. Maybe they'll fail, but I commend them for trying.

(I show her on X-Plane that it can be done in about an hour in a 172.)

It was when we did that in 2012. We left at noon and got there at midnight. 9 hours were just getting out of the Everett-Seattle-Tacoma-JBLM-Olympia I-5 nightmare. (Actually did 405-167-512 past Seattle/Tacoma)I'm always lamenting that personal air travel is never the fastest choice for places I actually want to go, so I had to lookup your locations to see where you live that it's such a big difference. Google Maps suggests 3:37 to drive the 220 miles between those two airports -- is it really 12 hours on busy travel days?? Wow, definitely get a plane!

I guess this conversation won't end with anything other than me admitting that you're right, soIn fairness, I'd be more comfortable flying a design that is capable of being flown by someone on the ground with no flight deck perspective.

I ride snowmobiles with belt drives... yeah they work but snowmobiles all have spots onboard to carry a spare belt and they can all be changed with either no tools or something small onboard. Why? Because they break fairly often, I usually replace one between our two snowmobiles every season.
I thought about that as well, and I went to be escrow.com site and they have all kinds of other partners like eBay and autotrader.com (which makes sense) as partners. Having a third party makes sense, as it does give credence to what they're doing.I'll commend them for trying, but not for collecting money from rubes.
It's not like anyone is EVER going to see the "refundable" deposit again.
That's also a good point. I'm trying to figure out how they make money on an "at cost" airplane, unless they get the first 1000 out there at cost, then turn up the profit, but they show it costing $173,000 and selling it for $130K. There is some wording on the site about getting discounts, and that's fair, but we're back to the shaving $43K off of it to break even, and then there's that whole "keeping the lights on" part of the enterprise.They are also presenting that thing as though it works, which is dishonest. How can they possibly know a price when they don't even have a complete design?
I'm hoping to do a trip to Cherokee County next summer. Maybe I can stop by the office and see what they are up to. With my background I may have a slight idea of how they are coming along.
I'm hoping they did a scale wind tunnel test before going to an RC model to verify their stability calculations. With CNC and rapid prototyping, it can now be VERY quick to make a wind tunnel model.
In airplanes? How about with 200+ HP engines?
I've seen nice belt drives in 80 HP snowmobiles. Nothing bigger.
Water cooling has been done in airplanes, but it is another part to fail. And automotive hoses really suck, and disable the vehicle when they fail. An unpressurized cooling system would probably fail better. I've only seen this in really old twin radials. Maybe it's been done elsewhere, but the twin thing would seem rather important.
Isn't there a guy on this very forum running a 400+hp water cooled Ford V8 through a belt drive on his experimental? I know I've watched the videos of him taking off in like 20'
Belt drives are really common in the piston rotorcraft world. The 300C, R22, and R44 all use belts to serve as a clutch between the engine and the rotor system.
I've never heard of one breaking in flight.

Interesting reading all these posts. I'm one of those "idiots" who gladly (still) put down money to make a reservation. The escrow.com account where the money is placed is there until either the project is completed and I can pick up the aircraft or I decide to get out. If I decide to get out - I'm out $100. I've lost worse than that on less.
If you compare the Raptor to the Velocity - which they are VERY similar in design, then add in the fact that the Velocity used design and materials from 30 years ago, update that to the latest materials and technology I can definitely see getting close to 300kts. I have personally spoken with owners of Velocity's who get 275kts in their aircraft. So speed is definitely achievable.
With computer modeling many of the traditional physical tasks can be done much more efficiently and faster at less of a cost. So I don't doubt many of the items put forth in this aircraft.
Let's discuss costs. The point of doing it the way he's proposing is a bulk-purchase to get the maximum discount and then passing it along. yes, there is the factor of you still have to pay someone to do the work to get the plane to the point of being build - or finished. O.k. - so, let's say he's off by a factor of 2. So if the plane was $260k instead of a $130k. Would you buy a plane for $260k that goes nearly 300kts on 7gph Jet A, pressurized 5 seater? I think most anyone would if they were looking for a plane with range and speed. The top-end Velocity is $450k, so even if the costs TRIPLE to $390k he'll still come in less than what the Velocity does and it beats the Velocity in gph and range.
Could it blow up in his face and come crashing down to earth? Sure. But I'm pretty sure the people who watched the Wright brothers tolling away in their bike shop said that thing would never fly either. If it fails, I'm out a $100 and I'll move on from there.
