- I built this Sonex Model ONEX in 2016. It is powered by a UL Power UL350is direct drive 130 HP engine with a Prince Prop. I have been asked many times what the top speed is. To answer that question once and for all, I did this speed run at Wharton Municipal airport KARM at sea level in Texas.
Nice!
Nice. Better than i expected. What engine are you using?
Ul Power UL350is 130 HP at 3,300 rpm. Prince Carbon/ Maple prop, 4 into 1 tuned exhaust no muffler burning 100 LL.............aircarft weight is 670 so power to weight ration5 lb per horsepower
Wow.
200mph, wow. What do you normally cruise at though?
I'm thinking of getting one of these and folding up the wings and trailering back and forth to the airport to save on hanger cost. Is there any reason that would be too much of a pain in the ass to do?
Do a lot of people do the UL350is engine?
You have to love to build aircraft, have the special skills to pull it off and the funds to buy the kit, motor, prop and electronics..................total cost for the project was $65,000 and 2 years of construction. It was my 6th aircraft after building an RV-4, RV-6, -7, -7A and another -7A. The engine is the UL Power 130 hp UL350is, fuel injected direct drive 3.5 liter 4 cylinder with a Prince Carbon fiber prop. the aircraft weighs in at a very light 645 pounds.
1:47 I think I saw 200 on there at 1:47
Dam….
sorry about the bad focus. The motor is light and powerful...perfect for an aircraft.....
@@carleldridge8317 impressive speed!
vne 216 mph
Yep, when I saw that rating I was sold and built the aircraft in 12 months, an easy build and flies like a little fighter plane..................fun stuff!
I thought VMax was 174kts...
174kts is 200mph
Multiply by 1.15 to covert to Mile per hour. We often use mph instead of knots
Impressive…. So it’s no longer light sport?
lol
@@FingerJam12What's so funny? It's a valid question.
@@la_old_salt2241 nothing i replied to wrong comment
Nope technically No...........way too fast. One reason I bought the ONEX was the aircraft has a never exceed of 215 mph, that is the engineering rating by Sonex Aircraft.. still can't believe that little thing has that rating
