Internal Power Milestone—EarthX Battery for the F1 Rocket Project - KITPLANES

1 week ago | kitplanes.com | Paul Dye

“The ship is now on internal power!”That’s always great to hear when launching a spacecraft—it means you’ve cleared the preflight checklist and are nearly free of all ground support equipment.
KitFlight Modernizes the Aircraft Builder’s Log

1 week ago | kitplanes.com | Omar Filipovic

Keeping a builder’s log is an important part of constructing an Experimental aircraft—but it’s rarely anyone’s favorite task. The KitFlight app aims to change that, offering a modern, mobile-first approach that turns documentation into a streamlined and insightful part of the build process. KitFlight runs on iPhone, iPad, and Mac computers and is designed specifically for Experimental aircraft builders.
USB-Powered CO Monitor from Radiant

1 week ago | kitplanes.com | Paul Dye

Radiant Technologies (www.radiantinstruments.com) has a penchant for using new and innovative technology to build inexpensive instrumentation for experimental and ultralight aviation. We’ve flown with their solid-state altimeters, airspeed indicators, angle of attack indicators, and turn-and-bank instruments—just to name a few. Their latest product is a compact, USB-powered carbon monoxide (CO) monitor that plugs into any powered USB-A port in your airplane.
BARC Gets Ready To Bite

2 weeks ago | kitplanes.com | Thomas Wilson

While biplanes have been racing for many decades, the class essentially dissolved in 2023 and has been re-invented for 2025. This all-new organization is called the Biplane Air Racing Class, or BARC for short. The first outing for the new class just concluded with their participation in the Pylon Racing School in Roswell, New Mexico. They’ll return to Roswell for racing in September.
600 MPH Jet Racing?

2 weeks ago | kitplanes.com | Thomas Wilson

We caught these interesting green dots on a course map for the Roswell air races. They’re well outside the already 10+-mile Unlimited/Sport course—something like 14 miles per lap. Now that looks like some he-man sport!Turns out they mark a concept floating around for a 600 mph course—meant for jets that are “more capable” than the L-39 trainers making up the current crop of Jet A burners. We fondly remember the first demonstration jet race at Reno ages ago.
New Course, Familiar Winds: PRS Lands in Roswell

2 weeks ago | kitplanes.com | Thomas Wilson

Air racing fans have been anticipating this week’s Pylon Racing School at Roswell, New Mexico, with various levels of hope and curiosity. It’s everyone’s first opportunity to see or run on the new pylon course—plus, anyone wanting to race in September must run on the course prior to racing, says the FAA. So you’d think the turnout by the end of the week would be large—as in, an entire field of seven classes.
Mack Daddy Cassutt

2 weeks ago | kitplanes.com | Thomas Wilson

It didn’t take long for Justin Phillipson to sell one of his three Formula 1 racing planes at the last Reno Air Races in 2023. He had barely hung a “For Sale” sign on #82—a relatively stock Cassutt—when Andy Mack bought it. It took a little egging on by fiancée Leah Sanfillipo, but not too much. The wonder is, when did Andy and Leah have time to prep their new race plane? Both are aerospace engineers with impressive experience.
Canopy Done—For Now: F1 Project Progresses - KITPLANES

2 weeks ago | kitplanes.com | Paul Dye

It’s been a while since we provided an update on the big picture of our F1 project—mostly because we’ve been heads-down, working on the many details of fitting and assembling the canopy and its skirts. To bring those following along up to speed: The fuselage is at the point where we’re nearly ready to put it on the gear and hang the engine, so we can start the firewall-forward work—engine systems, baffles, and cowling.
Oshkosh 2025 NOTAM Includes Key Updates for Pilots Flying In

2 weeks ago | kitplanes.com | Omar Filipovic

Planning to fly to EAA AirVenture Oshkosh 2025? Be sure to download the updated Oshkosh Notice (commonly known as the NOTAM), which outlines FAA-approved arrival and departure procedures for this year’s fly-in, set for July 21–27 at Wittman Regional Airport. The 2025 Notice is effective from noon CDT on Thursday, July 17, through noon CDT on Monday, July 28, and applies to aircraft arriving at both Oshkosh and surrounding airports.
Aircraft Modification Choices

2 weeks ago | kitplanes.com | Vic Syracuse

One of the reasons certain amateur-built aircraft models have been so popular is because there is a whole cottage industry of aftermarket items available for them. Initially this effort was focused on tools to facilitate the build process. We saw improvements in dimple dies, fiberglass cloth cutters and complete “starter” tool kits being marketed to first-time builders.
