My grandfather, Bob Frownfelter served and flew in 2 wars. Shot down behind enemy lines and was able to make his way to a station where eventually the nurse that saved him became my grandmother Edith Frownfelter. He was a well known gentleman of the Aor Force. RIP .....Sadly I never flew. Never got the chance. Since youtube has been a thing I've watched so many flight shows, but this little craft is so amazing. Great job gentleman. Way to Go Bob!
"Take it to the break...such as it is" I am so deeply smitten by this little bird I can't tell ya. Given the advancements in microturbine technology recently I hope we start seeing a lot more of these 1 and 2 place jets
I've seen a few that were converted from piston engine props to these microturbines. Absolutely amazing. Of course, in that case, CG is a concern. But it's doable!
INCREDIBLE! Sonex has REALLY come a long way... I've never wanted one more than I do right now... haha. I've always loved the cool, sporty, sleek lines of a Sonex. Man, I miss flying so badly, combat PTSD can suck it.... Semper FI!
I extracted my shopvac motor assembly and mounted it to my homebuilt plane all while my wife watched.......I was able to takeoff within 75 miles of runway!!! It was awesome......😂😂😂😂
Power by hair dryer. ABs by Hair Spray. Each plane comes with shoe horn and can opener for entry/egress. FAA does not recommend for claustrophobic pilots. For everyone else, just make sure you bring lots and lots of hair spray. All kidding aside, nice looking little (*LITTLE*) plane. I would measure shoulder width before trying to climb inside. Short people, have fun.
11:49 I don't think you are supposed to retract the gear until you see positive rate. Flaps to x (usually the same degree as full aileron down deflection), positive rate, gear up, x speed, flaps up, configuration check. I like the entire video, but this is my favorite segment: 17:01 0:00 Meaningless chatter. 1:39 Checklist, engine start, taxi. 3:14 Rejected take off on ground. 4:53 Normal take off. 6:06 Slow flight and stalls. 12:12 Return to airport for simulated flame out approach. 14:16 Go around. 15:38 No flap approach and landing. 17:01 High speed pass. 17:13 Normal landing.
Very nicely done ride sir. It does appear that perhaps a little more of an overhang from the glare shield would help. I noticed in several other videos as well as this one the pilot having to take a hand off the controls in order to shade the PFD in order to read it.
A thrust reverser would be a nice option to save those tiny brakes. Perhaps an afterburner to get out of smaller strips too. Id like to see a little more angle on the departure stall and some deep incipient spins too. Guaranteed, someone is going to do it inadvertently one day.
Very interesting & informative check ride ops for that Jet. Gives a very good perspective of expectations for basic skills to operated this aircraft. Of course, high altitude descents and instrument ops will be essential as well.
+southnc63 Optimum altitudes are from 10,000 to 18,000 feet so high altitude operations are not really a factor. As far as approaches and instrument procedures are concerned, the aircraft is not really equipped for IFR and those ops would come under emergency procedures
An I think of the R/C modeler that build those huge models and I say "look for a little more you can build something YOU can get into and fly! And you can go somewhere!" That's what a homebuilt is all about, freedom!
What a beautiful ride! And an amazing little plane. Ahem,.. good pilot too! :o) It still makes me laugh to see that teeny tiny jet engine on the back. Modern tech absolutely amazes me,..but i'm always thinking "what's next? 900+ MPH planes with no sonic BOOM?" When is the next big leap in aviation? It's ALWAYS right around the corner.
Superb pilot. Fantastic handling little jet. Very impressive. I have one question: Let's say I have a quick job to do in Iowa @DSM. No, that's not an ideal thing, so I want to fly my jet, but is there enough room for a well-packed "carry on" back there with the BRS and fuel somewhere?
I saw another video with a Sonex pilot he said there's enough room for your toothbrush and your credit card, and that between the himself and full tank, he's 5 pounds under max... and he wasn't a large man, so I guess that answers your question.
@@garrykennedy5484 he mentioned airspeed first time after he landed and was leaving the runway. Only other time was at 10k altitude in a decending turn. IAS should be his primary instrument to be aware of and mentioning it. Scary pilot!
This aircraft reminds me of something I'd make in X-Plane's PlaneMaker. except that it has excellent stall characteristics and low-speed handling in general. I wish I could pass FAA medical, cuz I'd find a way to get one.
1. Do you know for sure you cannot get one? 2. If you really want to fly you do NOT require a FAA medical for some planes/operations 3. Are you just using the non-medical as an excuse to not fly?
I can’t believe that little beer can on top of that plane can actually move that thing at all! What, is that fan about 8 inches across, if that???? That is INSANE!
Sonex Aircraft LLC: check at FAA Aircraft Certification.com. The Amateur built Operating Limitations. I believe your remarks about its spin behaviour and absolutely love your fantastic aircraft.
interesting video. I was expecting more commentary like take-off speed attained, altitude is, airspeed is, any buffet when approaching stall, fuel state, climb rate is, etc etc especially as it is a 'check ride'
Hello from Spain, I really bob that plane. I've seen the cri cri videos with double tj40 and I find it interesting. What price do you have in Spain? Thank you
On the landing approaches, what does he keep turning off/on as he nears the ground? It sounds like he's saying FDD? Googling indicates it might be Fault Detection & Diagnostics if that's it, why off/on during landing?
It’s “PDB”. The engine has a protection system in which the computer will shut the engine down if it reads a certain temperature or other variables. Turning on the PDB disables that protection system, and is used for take-off and landing.
Considering this little guy burns around 20 gallons an hour. I'm betting a Bonanza with a jet would cost as much as a private jet. Probably more viable to go and buy a Premier
I’m not a pilot and have zero knowledge of these things. Noticing some yaw when rolling at speed - is that just because of the closely couple gear geometry? Or something else?
For a very, very, specific commuter demographic, this little "Point-A" to "Point-B" jet makes some sense if flying from one home to another. Cruise: 210 kn (240 mph, 390 km/h), VNE: 249 kn (287 mph, 462 km/h), Range: 420 nmi (480 mi, 770 km) with 30 minute reserve. For nearly everyone else on the planet, not so much. Don't get me wrong, I appreciate it for what it is... a 250 MPH jet, for one, but hampered by virtually no usable storage.
The speeds seem excessively high. I am guessing the airspeed is in MPH since if it was knots it would be really high. The factory stall shows 58mph and it was shaking and stalling over 72mph. I kinda thought this was just "another" Sonex. What am I not seeing?
@@SonexLLC , Interesting. I would like to see an "aggravated" stall where you pull the nose up and let it "fall". How about spins? I know on my own Sonex the "dirty" stall is nothing more than buffeting and a 1500fpm descent. The clean stall is a little break. The power on stall is suddenly upside down and looking at the ground!
Okay, I made a smart-assed comment, but here's the deal. Jim Bede made some pretty interesting airplanes, but I think the BD-5 and BD-5J were a bit too much for him. The kits, when you could get them, were often missing parts, had alignment issues and were overall, poorly made. Furthermore, there were very few of them available. Jim's company was not doing well at the time, and he never really fully recovered from quality issues. If you took the drawings and made an airplane directly from the drawings, you might be able to cobble something together that would be close to what it was intended to be from the start. The aircraft could be done again today, with today's standards and builder assist, and you'd have a great airplane, but no one wants to take on the old design. It could easily be made into a composite design, but either the plans, the trademark, or the design rights aren't available, or, more likely, no one wants to take on the project. It WOULD be interesting to see a slightly scaled up model with a P&W 600 series turbofan in it, and I think it could be done, maybe a two seat version. An inbetween of the BD-5 and the BD-10. might be interesting. Infor on the BD5 series of aircraft: en.wikipedia.org/wiki/Bede_BD-5
I hope that cockpit isnt that quiet. If it is I would never fly this thing. That white noise would make me real sleepy real quick....hehe...plus the flight looks smooth as glass.
***** Absolutely serious, Thank you for the information, I will get together with my wife later this evening and discuss this with her before i make any moves, Again thank you.
I enjoyed this very skilled and extremely professional pilot as much as the aircraft. I'd feel secure with him at the controls anytime. I'm wondering how many hours he has under his belt? And what other ratings he has, to have a man be so adept?
+discerningmind I've got about 18000 hours in various airplanes, rotorcraft and gliders but this little bird with the Hershey bar wing is a pussycat to fly. If you remember that you are in a TJet powered aircraft and use the checklist, you won't have any problems at all. Basic flying skills apply
@@robertohaver9116 . Why did I see you only use a checklist when starting the engine? In my few hours of training, I always used a checklist on landing. It would seem especially important on an aircraft with retractable gear!
In this case (a small fast mover) there are only three items to do on the checklist in the pattern. Remember that the checklist is not a "do list". Speed to 120 kts or less, flaps, and gear down as a memory item. I always vocally "check three green" on final. The critical stuff is engine start and pre-departure issues. Once you're airborne, there is very little to do
Just found this video. Bob gave me my private checkride. What a freakin legend.

Nah , just kidding...It's for " Pitch Trim "....
Never heard the pilot even mention it, but to me the three most important things flying any aircraft is: airspeed, airspeed, and airspeed. :-)
He says it a few times. It's when he puts the throttle back on.
@@garrykennedy5484

All I wanna know is did the visiting DPE still charge his checkride fee? :)-
Seems like it needs brighter landing gear indicators, and a slightly bigger glare shield.
Would it be feasible to fit a ten gallon drop tank under each wing? Thus increasing range.
I can’t believe that little beer can on top of that plane can actually move that thing at all! What, is that fan about 8 inches across, if that???? That is INSANE!
Shouldn't a spin be a part of the complete flight testing of any new GA aircraft?

I am a little confused when it comes to the JSX-2, is it still a prototype or is the one that is currently available for sale?
And is the airplane in the video JSX-1 or 2? I guess this is 1 because of the instruments layout?
the movement of the stick looks like it would be too sensitive particularly at high speeds
It's at high speeds that it needs to be sensitive.
You got it backwards bro but thank you for trying to contribute to the conversation.

So how do you learn to fly one of these to get good enough for the checkride if it’s a single seat aircraft?

Considering this little guy burns around 20 gallons an hour. I'm betting a Bonanza with a jet would cost as much as a private jet. Probably more viable to go and buy a Premier
There's a bit of a difference in weight.

I’m not a pilot and have zero knowledge of these things. Noticing some yaw when rolling at speed - is that just because of the closely couple gear geometry? Or something else?
hmm what location was this filmed at?? looks like wyoming
I feel like a noob asking this question, but why was the plane so wobbly on the touch and goes? Is it THAT light or was it windy?
Plane starts moving then he releases parking brakes, I think they're not adjusted correctly.
That little beauty reminds me of the Bede BD-5J, only prettier.
considerably safer, too. The BD-5 is notoriously difficult to fly.
Lucky it never gets to high speed
Why can't they manufacture a Cessna 172 with those stall characteristics!
That fisheye lens started to give me a headache
How much time can you cycle the gear before it ran out of air pressure?
thats an awesome little jet, kinda looks like a drone
What are the guidelines flying this state to state?
