I’ve practised it at height enough to know that I can do it pretty well …. at height when I’m practising.
-
It's on the to-do list.

Some of you have probably already seen this, but for those that haven't it's an interview with Rian Johnson, Vans CEO and chief designer about the thinking and development of the RV-15. It's clear that the current aircraft is about testing their ideas rather than a pre-production aircraft. Also interesting that they've been mulling over the idea of building a high wing for about 20 years now. They are putting some solid engineering and marketing thought into this plane, and I think it's going to be successful aircraft for a variety of customers, although probably not me unfortunately. They are also planning to develop a trainer version which may mean they intend building it themselves as they do the RV-12. Homebuilt aircraft have come a long way in the last 50 years.

I averaged A$1.00 to US$99c. Friends did really well and bought their full RV-12 kit just as the rate hit A$1.00 = US$1.10, but today A$1.00 will get you just US$0.69. The exchange rate has a big effect on your build cost.

I suspect it will be up there with the RV10 in cost, but I don't think RV's are overpriced for what you get in terms of kit quality and aircraft performance. You can also add a lot of extra cost to the basic kit by your own decisions. For example, most RV10 builders seem put enough avionics in their panels to pay for a decent used Cessna. A US$40-$60k panel is pretty average. What really hurts builders over here is the exchange rate and freight. My RV-12 cost $96k finished and flying in 2015. Today it would cost me at least $140k.

Here's a pretty comprehensive Kitplanes article on the design that should answer a lot of questions: https://www.kitplanes.com/vans-rv-15-on-top/

Link to RV-15 prototype photos for those interested. https://dougreeves.smugmug.com/RV-15-Engineering-Prototype/ They flew it to Oshkosh, although haven't released any performance details yet. Wingspan is about 35' and it has a 215hp engine, so a pretty decent sized plane for a homebuild. Should be a successful plane for Vans, but you will probably need deep pockets to build one.

Methusala, I object to your claim that Bob Dylan can sing.
-
Methusala, I think your research into the ‘facts’ is leading you down a lot of rabbit holes. The bottom line is the Ukrainians want Putin to mind his own business and get out of their country.
-
I'm surprised they said as much as they did in front of a camera. Most even called it a war.
-
Just guessing, but I think they will design it to be as versatile as possible, so at one end it may be a Cessna with 180 hp fixed pitch for those who just want a reasonably fast high wing tourer that's easy to get in and out of, with good carrying capacity and maybe 2+2 seating, while others will want a 250hp bush plane with a constant speed prop, tundra tyres or floats, perspex doors and able to fit a moose or grizzly in the back. They may even come out with a tri-gear version -15A. Whatever they do, it's likely to be a couple of years before the first builder gets one flying. They can't even keep up with the orders they already have due mainly to supply chain issues.
-
Nobody would argue that the first casualty of war is truth and that there are two sides to every story, but are you saying that the west is ultimately responsible for the current special military operation because it left Putin with no other choice but to invade a neighbouring country?
-
Vans use 2024-T3 Alclad aluminium alloy for wing and fuselage skins. This has a pure aluminium coating on both sides which oxidises and provides corrosion protection. It needs to be scuffed and cleaned before priming and painting. Some builders like to polish it (hard work) but most paint their aircraft. As a prototype there isn’t much point painting this particular RV.
-
Also has a stabilator and articulated main gear. Not many details released yet, but will be interesting to see how it compares with similar aircraft. Should do well, but won't be cheap - especially with our current exchange rate.
-
Just a prototype at this stage.

Makes me think back to a takeoff I once did in a C152 as a solo student doing circuits. I had just started my takeoff run when a yellow rescue helicopter on an emergency call lifted off and crossed the runway climbing left to right about two thirds of the way down the strip, cutting across other aircraft in the circuit as it left the area. I continued my takeoff not even thinking about wake turbulence and fortunately without incident, other than being surprised by the sudden appearance of the helicopter crossing my path. Must have been lucky enough to have either passed under or climbed over the wake by the time I reached the spot. We have Ericson Aircranes and other fire fighting helicopters based at out airfield every summer, and we're repeatedly warned about wake turbulence when they are operating.

So what do people do these days when making a flight plan?

What aircraft do you fly? -
Good, but when?
-
Maybe the owner was a seat of the pants flyer.

OME, the wings don’t know which way the wind is blowing when the plane is in the air. It does when the plane is stationary on the ground. Thats why you take off into the wind - to take advantage of the air flowing over the wings in order to reduce the length of your ground run. Same with landing. But once you’re off the ground the airspeed is the the speed of the plane through the air, or the speed of the air over the wings if you prefer. Your example of a glider being stationary while flying into the wind just illustrates the difference between ground speed and airspeed. As far as the glider is concerned it is flying at a speed that happens to match the wind speed over the ground.
-
Except that you will lose height making the turn so you need to factor that in.
-
Good video but the narrator's style and background sound is pretty woeful.
-
It depends. You should know if there are suitable places to put down in the country you’ve just flown over. If so and they are within gliding distance that may be the better option especially if yo can turn back into wind on final. On the other hand if you’re over tiger country your best bet may be to continue and find the most survivable spot you can.

Emergency landing and inversion 13/06/2022

Matching colours? -
Mine cost $6500 by an auto shop with previous aircraft painting experience in 2014. Three colours, no heavy coats. That included all prep including finishing all the fibreglass. I thought it was good value. Another builder just had his RV12 painted by a well known local aircraft painter - also three colours and I think he paid $16,000.
