Sonex-B First Flight: Leroy Brandt

Congratulations to Leroy Brandt of Dane, Wisconsin, whose Sonex-B Conversion (S/N 0393B) Flew for the first time on November 28th! Leroy's UL 260iS Powered, Tri-Gear aircraft is the first customer B-Model example to fly!

" flew very well," writes Leroy. "Thanks to my ground crew Jerry, cal and Hallis. This is going to be a fun airplane again." Gold Wings are on the way!

Special Note: Customer already had a UL Power engine available for this project, but it did not have the prop hub length specified for a Sonex Aircraft B-Model, which is the reason for the top cowling modifications shown. With the Sonex-specified prop hub length, no modifications are required to the B-Model cowling for UL Power engines.

At AirVenture, Bob Carlton told Aero-News that the jet is everything one might expect in a Very, Very Light Jet. Isn't it about time you checked that item off of your bucket list? It's time to Get Your Jet!

SubSonex Update: Builders Enjoying Their Jets!

Tom Larkin flying with Sonex airshow pilot Bob Carlton in New Mexico.

We've received quite a bit of correspondence over the past couple months from SubSonex builders who are enjoying the heck out of their jets!

Tom Larkin of Brighton, CO and owner of JSX0003 recently made a trip to Moriarty, NM with his SubSonex to do some flying with SubSonex test pilot and airshow pilot Bob Carlton, and managed to get an air-to-air photo shoot by Mark Mocho: the first two-ship formation SubSonex photo mission ever!

Andrew San Marco of Fairfield, CT and owner of JSX0007 had his very meticulously built SubSonex painted to match his Valmet/Aermacchi RediGO turboprop. Professional photographer Andy Zink had a great time making some great pictures with Andrew and the SubSonex.

John Corneal of Petersburg, PA and owner of JSX0006 wins the award for having the most fun in his SubSonex, having brought it to EAA AirVenture Oshkosh 2017 as the first customer-built SubSonex to appear at the show. As we reported in August, John took home a Kit Champion Bronze Lindy Award for his SubSonex and did an air-to-air photo shoot with the EAA team, along with several interviews. Look for a feature story about John Corneal's SubSonex to appear in the February, 2018 issue of EAA Sport Aviation Magazine. John was also featured at the beginning of a new EAA video spot released just this week (see below). "Holy Grail- a vessel with miraculous powers that provide happiness, eternal youth or sustenance in infinite abundance. Yes, that's what I'm talking about!" writes John.

Congratulations to Tim Mobbs of Seething, Norfolk, England, whose AeroVee Powered, Standard-Gear Sonex (S/N 1555) flew for the first time on November 9th! "The test programme is continuing well," writes Tim. "From 1943, Seething was the base of the 448th Bomb Group of the USAAF and their 'assembly ship' was a yellow and black chequered B24 called 'You Cawn't Miss It.' So my Sonex (registered G-YCMI) is also chequered in part, and we have incorporated the black letter 'I' on a white circle born by all the Seething based Liberators." Gold Wings are on the way!
