All of us dream of reaching a point in life where we have the knowledge, skills, energy and resources to pull off builds that match our wildest dreams. [Mike Patey] is living that dream and with a passion for engineering and aviation that is absolutely infectious, he built Draco, the world’s most badass bush plane.
Draco started life as a PZL-104MA Wilga 2000, which already had impressive short take off and landing (STOL) capabilities for a 4 seater. Its original 300 hp Lycoming piston engine failed catastrophically in 2017, very nearly dumping [Mike] in Lake Utah. He decided it was a good excuse to start building his dream plane, and replaced the motor with a Pratt & Whitney PT6 turboprop engine, putting out a massive 680 hp.
Almost the entire plane was upgraded, and the engineering that went into it is awe-inspiring, especially considering that [Mike] did most of it himself. This includes a redesigned fuel system, enlarged wing and control surfaces, new avionics, oxygen system, upgraded landing gear and an array of lights. The wing tip landing lights are actually from a Boeing 737. [Mike] estimates that the upgrades cost somewhere in the region of a million US dollars. All the highlights of the build is documented in series of videos on [Mike]’s YouTube channel. What we would give for a personal workshop like that…
Try not to let your jaw hit the floor when watching the video after the break.

In a 1999 movie (Pushing Tin), a flight controller is a passenger on a plane and tells the flight attendant that he needs to speak to the person controlling the plane. The flight attendant tells him the pilot is very busy to which the controller responds, “…you really think the pilot is controlling this plane? That would really scare me.” We wonder what that fictional character would think flying into Loveland Colorado. Their Colorado Remote Tower Project. While there’s still a human flight controller, they aren’t physically located at the airport and rely on remote cameras and radar so the controller can be located elsewhere.
The subject airport is the Northern Colorado Regional Airport and is the state’s busiest airport that has no tower. While the concept — generically known as Remote and Virtual Tower or RVT — dates back to 2002, its adoption is only now starting to pick up steam. An airport in Sweden was the first to go live for normal use in April of 2015, but the Colorado installation is the first approved in the United States. If the official site is a little too dry for you, there’s a CBS report with a video that gives you a quick overview of what’s happening. Or dive in with the demonstration video you can see below.

SpaceX just concluded 2017 by launching 10 Iridium NEXT satellites. A footnote on the launch was the “hosted payload” on board each of the satellites: a small box of equipment from Aireon. They will track every aircraft around the world in real-time, something that has been technically possible but nobody claimed they could do it economically until now.
Challenge one: avoid adding cost to aircraft. Instead of using expensive satcom or adding dedicated gear, Aireon listen to ADS-B equipment already installed as part of international air traffic control modernization. But since ADS-B was designed for aircraft-to-aircraft and aircraft-to-ground, Aireon had some challenges to overcome. Like the fact ADS-B antenna is commonly mounted on the belly of an aircraft blocking direct path to satellite.
Challenge two: hear ADS-B everywhere and do it for less. Today we can track aircraft when they are flying over land, but out in the middle of the ocean, there are no receivers in range except possibly other aircraft. Aireon needed a lot of low-orbit satellites to ensure you are in range no matter where you are. Piggybacking on Iridium gives them coverage at a fraction of the cost of building their own satellites.

Anyone who’s into retro aviation gear falls in love with those mysterious displays, dials, keypads, banks of knife switches. There’s a lot of sexy in those devices, built with high standards in a time when a lot of it was assembled by hand.
[Jeremy Gilbert] bought a 747-200’s Control Display Unit (CDU)– the interface with the late ’70s in-flight computer–and is bringing it back to life in a Hackaday.io project. His goal is to get it to light up and operate just as if it were installed in a 747.
Of particular interest is the display, which turned out to consist of a series of 5×7 matrices (seen on the right) controlled by chips no one uses any more. However, [Jeremy] found a blog post where someone had hacked out Arduino code for a cousin of the chip, saving him a lot of time. However, he’s got a lot more sleuthing yet to do.
If you’re into retro displays, we’ve mentioned a number of good ones, including the legendary Apollo DSKY and an awesome retrocomputer.
Parts, tools, and components for aviation and aerospace are sold in ‘Aviation Monetary Units’ (AMU). Right now, the conversion factor from USD to AMU is about 1000 to 1. This stuff is expensive, but there is a small portion of the flying community that prides itself on not breaking the bank every time something needs to be replaced. Theses are often the microlight, ultralight, and experimental aircraft enthusiasts. Steam gauges are becoming obsolete and expensive to repair, and you’re not going to throw a 15 AMU Garmin G500 in an ultralight that only costs 10 AMU.
To solve this problem, [Rene] is turning to sensors, displays, and microcontrollers that are cheap and readily available to build modular aviation instruments.
As with all aviation gear, the first question that springs to mind is, ‘what will the FAA think about this?’. [Rene] is in South Africa, so the answer is, ‘nothing’. If a few American pilots decide to build one of these, that’ll fly too; these are instruments designed for non-type-certified aircraft. That’s not to say there are no rules for what goes into these aircraft, but the paperwork is much easier.
Right now, the design goals for [Rene]’s instruments is under 0.1 AMU per module, robust, RF shielded, with engine monitoring, fuel management, heading, air and ground speed, altitude, attitude, and all the other gauges that make flying easy. He’s using a CAN bus for all of these modules, and in the process slowly dragging the state of the art of ultralight aviation into the 1990s. It’s fantastic work, and we can’t wait to see some of these modules in the air.
The history of aviation is a fascinating one, spanning more than two thousand years starting from kites and tower jumping. Many hackers are also aviation fans, and the name of Alberto Santos Dumont may be familiar, but if not, here we talk about his role and accomplishments in the field. Santos Dumont is one of the few aviation pioneers that made contributions in both balloons, airships and heavier-than-air aircraft.

Every hobby needs to have a few people who take it just a little too far. In particular, the aviation hobbies – Radio control flying, FPV multicopter racing, and the like – seem to inspire more than their fair share of hard-core builds. In witness whereof we present this over-the-top home-brew flight simulator.
His wife and friends think he’s crazy, and we agree. But [XPilotSimPro] is that special kind of crazy that it takes to advance the state of the art, and we applaud him for that. A long-time fan of flight simulator games, he was lucky enough to log some time in a real 737 simulator. That seems to be where he caught the DIY bug. The video after the break is a whirlwind tour of the main part of his build, which does not seek to faithfully reproduce any particular cockpit as much as create a plausibly awesome one. Built on a PVC pipe frame with plywood panels, the cockpit is bristling with LCD panels, flight instruments, and bays of avionics that look like they came out of a cockpit. The simulator sits facing a wall with an overhead LCD projector providing views of the outside world. An overhead panel sporting yet more LCD panels and instruments was a recent addition. The whole thing is powered by a hefty looking gaming rig running X-Plane, allowing [XPilotSimPro] to take on any aviation challenge, including landing an Embraer 109 on the deck of the USS Nimitz Aircraft Carrier.
What could be next for [XPilotSimPro]’s simulator? How about adding a little motion control with pneumatics? Or better still, how about using a real 737 cockpit as a simulator?
