The video is a walk around my ONEX aircraft that I built from a Sonex Kit. It powered by a UL Power UL350IS 130 hp direct drive fuel injected engine spinning a 56 X 66 Prince Carbon Prop.
The ONEX has a climb rate of 1,500 fpm at sea level 110 mph. Flying the ONEX: Take off is a challenge due to the high P-factor, lots of right rudder and attention to keep on the runway. Landing is easy, one of the easiest taildragger to land I have ever flown!! Aerobatics: roll rate, full roll 3 seconds with a Red line Never exceed speed of 216 mph!
Thanks Mike, A Paint shop in Texas, Top Gun Aircraft Paint from Mason, Tx did the paint. A really talented guy, PPG base coat clear coat. I have really enjoyed the comments while at Oshkosh and Sun and Fun. The inspiration for the paint was, the top stripes on a black and white Skunk, a cool appearance for Nature itself!
Thank you! I have enjoyed the little bird for 4 years now and have almost 200 hours of flight time. Sonex really did a great job designing the airframe and folding wings......congrats to their engineering staff!!
Thank you, Stephen. I have enjoyed the little ONEX and the construction was very simple, all pop rivets and great assembly manual. Build time was 12 months Started in November completed in November and flown in January.
If you are pilot and love to fly you can not go wrong with the ONEX, small light and fast. If you want to take a passenger consider the Sonex. If you get started and need a little advice or encouragement let me know .......I would be happy to help.
Carl, that is a very well maintained machine with a lot of attention to detail. Would you mind elaborating a bit more about how you embed the brake line and how you reinforced the wing? Thanks!
The trailing edge of the landing gear is were you glue the plastic 1/4 inch brake using hot melt glue. Then epoxy micro ballon putty is applied and left to cure,then is sanded to cover and hide the brake line in an aerodynamic trailing edge. This is then over laid with a single ply of fiber glass for protection then painted. A very trouble free an beautiful solution.
Ok, the fuel burn is 6 GPH so if you do the math that's a 2 hour endurance on the 16 gallon tank. so at 165 mph the range comes out to 300 mile with reserve. You gotta look for a fuel stop every two hours....
Yes, I did not show the baggage compartment rated at 30 lb The floor of the baggage compartment is actually a nylon window net required by SCCA and Nascar racing, a great way to keep the weight off of the fuselage bottom a really light as a bonus. When I went to Oshkosh I took a sleeping bag and travel bag, no problem.
The vortex generator is by Stolspeed, the spacing is 2.5 inches and located 3.5 inches back at 7% of the cord of the wing. They seem to have no effect on cruise speed. They lowered the stall speed from 54 mph to 49 mph. The biggest benefit was the landing characteristic change. When you raised the nose for the landing flare, the ONEX would drop hard to the runway before the installation of the VG's , after the VG's were install the ONEX now very gently settles onto the runway smoothly. This was an unexpected flight performance improvement!!
The UL 350is is the 130 hp @3,300 Rpm. The Prince Prop is a carbon over maple P-tip with 54 inch dia and 64 inch pitch which really hooks up in climd and indicates 3150 rpm for a quick and short take-off. The rudder had to be extended by 3 inches to handle the big P-factor, right rudder on take off is big!
Sorry for not getting back to you sooner. The Dynon panel was $10 K and the Ul Power Engine was a very costly $24 k Prop by Prince $1,500 dual Lithium Ion batteries $700 Actually lost count of the total expense during construction and then did a $4,500 paint job....yep airplanes are not cheap....
I am retired and am an experience builder having built 6 Van's Aircraft Types, so I was taxi testing at 12 months and flying in 13 months. Pop rivets are easy and the kit is very well designed and complete.
You Lucky Duck! That's The Nicest Onex I've Ever Seen.

Beautiful plane. Very nice job on the details. 👍
Glad to finally see a walk around of this plane .
Beautiful plane and awesome upgrades!
Solid walkaround Carl, Thanks
Nicely done plane.

Bro 👌 this is the most Ulta coolest Sonex I've ever seen bravo 👏🏻✌🏻 not just because I love yellow and white and black lol 😂 all the best 🏆🥇🛫🛩️🇺🇸

Very nice aircraft

THanks for the walk around! Im retiring in the spring and going to build a Onex. I hope to use the UL Power engine as you have done.
If you are pilot and love to fly you can not go wrong with the ONEX, small light and fast. If you want to take a passenger consider the Sonex. If you get started and need a little advice or encouragement let me know .......I would be happy to help.
Good job.
Thanks Don. I appreciate your comment. It's been a fun experience.
Nice...
Thank you, Carl

I've always wanted to see the wingfold demonstration. Which direction you push-pull and how the wing actually moves.
Here’s a video with a demonstration of the wing hold towards the end;

Your airplane is very nice. May I ask how you like it as a long cross-country airplane, say flights of 3-4 hours duration? Thanks.

I love these Onex's Yours is beautiful! Is there a spot to put a small backpack or a duffel bag?

Where did you get the vortex generators and how did you decide on the number and spacing? Also do they affect your cruise speed?

@@carleldridge8317 Thanks for the information.
Nice airplane, Carl. Which model of UL engine did you install?

How much extra did you spend for the extras.

How long did it take to build?
