Quite an accomplishment with no pressurization. It had to be pretty chilly up there. Great visuals though. You should consider changing the music and dropping the volume for a better viewer experience. Have you published any technical details of the flight? How long do you think you could have stayed up there if you had an RVSM ticket and clearance? Congrats on FL 300.

[@GaryLaaks1]

Congratulations guys. So proud to see such a fantastic success story out of South Africa. Greetings from Port Elizabeth.

[@joycethomas8868]

It would have been nice to see the engine, turbo combo and any additional info on prop and power source. Nice video...congrats. What power settings and airspeed were you getting at 29,000’?

[@USA-GreedyMenOfNoIntegrity]

From my rough calculations 143 KTAS. Most likely WOT. Rotax 915 Turbocharged! It’s all in their videos.

[@flyboycpa]

Not sure how much high altitude experience you guys have, but you're required to set your altimeters to 29.92" upon passing 18,000' (FL180). Thankfully, with them set to 29.89" you weren't too far off, but that could get ugly with a/c separation had there been a really high [or low] baro upon your departure at KTOA.

[@Captndarty]

Amateur hour. Not exactly sure how they got into RVSM either ....

[@Van-tastic]

ATC can allow local altimeter and path clearance for approved test aircraft.

[@pilotavery]

You can operate an RVSM airspace if you want to, as long as your experimental aircraft is capable of maintaining 200 ft accuracy. If you've already done engineering analysis, which in today's time, means checking with GPS and making sure that your GPS calibrated altitude and your indicated altitude are within 100 ft of each other, You are fine. With modern technology it's easy to meet these minimum requirements. However, should there be a separation issue, and an investigation is done that shows your aircraft has never been capable of RVSM standards, You may be subject to penalty. Can an operator, in an experimental aircraft, operate in RVSM airspace (1000’ separation standard) if equipped with ADS-B Out? An operator may file a “w” in field 10 of the ICAO flight plan and operate in U.S. RVSM airspace with 1000’ separation if they meet the appropriate provisions of Part 91 Appendix G including Section 9, regardless of the airworthiness certificate they hold (Standard or Special such as for experimental operations). Appendix G, section 3 authorizes specific operators to operate aircraft with FAA certified designs that meet the specifications of Appendix G section 2 to operate filing /W. Appendix G section 9 authorizes operators of aircraft equipped with ADS-B OUT systems capable of maintaining an altimetry system error performance standard of not to exceed 200’ to operate filing “w”. It is important to note that ADS-B out provides continual ASE monitoring of an aircraft but does nothing to assure required ASE performance. An operator of a properly equipped and maintained aircraft with a certified RVSM design has reasonable assurance their aircraft ASE will not exceed 200’. An operator of a properly equipped and maintained aircraft that does not hold a RVSM certified design will need to complete appropriate engineering analysis and testing to assure their aircraft ASE will not exceed 200’. An aircraft operated as RVSM compliant (filing /W) under section 9 that exceeds 200’ ASE will be out-of-compliance with the rule and could also lead to investigation for reckless and or unsafe operations.

Does the G3X not flash the altimeter setting for STD Baro after passing FL180? At 12:07 is looks like the setting is 29.89, not 29.92

[@4n6iscool]

Awesome! Thanks for the vid. It would have been dry and boring without some background music. I had no problems hearing all the radio calls with the music volume.

[@EJWash57]

Why dub in music so LOUD when folks are speaking? Hard enough to hear them as it is! Especially ATC.

[@Vspeeds]

You need to make the title “flying a Sling TSI to 30,000 ft” if you want to see these views fly as high as your airplane does.

[@ryanadventureeverything8758]

29,000 to 41,000 ft is RVSM airspace. Requires special aircraft and pilot requirements.

I'm obsessing over this damn plane. The Rotax 915is is listed for a service ceiling of 23k feet. I'm curious if the team collaborated with Rotax beforehand and/or shared performance data after the flight?

[@SlingPilotAcademy]

Yes - we spoke with the Rotax engineers from Austria at Oshkosh last year. They have had drones over 30,000 ft as well.

Could you tell us where to get the connection piece attached to your headset for your GoPro?

[@SlingPilotAcademy]

We made it using mounting parts we bought on Amazon

[@Digital-Dan]

Music of any kind never improves videos like this for me. Ascending and descending arpeggios are in particular kind of inappropriate for a flight that intends to go only one direction. :-)

[@thomasmiller1650]

Agreed, aviation people seem compelled to use music to muffle the sounds we really want to hear.

[@ahmadbijarchi5384]

high is good and is proud . fly in CB turbulence please. tank you

[@ilikeplanes]

Congrats, great video. At time 12.20 why did you edit out the left turn? I am curious as to how the altitude effects he performance in non level flight

[@mlehky]

Same question, aileron control must have been pretty mushy.

[@mlehky]

Did you switch the prop to manual or use auto climb all the way?

[@mlehky]

What was the actual time to climb to FL300? Also why evening? Wouldn’t have been cooler out first thing in the morning?

just trying to make video a little shorter

[@SlingPilotAcademy]

Just used auto. We tried manual on a previous ceiling test and found auto to work just as well.

[@robolt71]

How did you get away the requirement and approval with RVSM at FL 290 and above?

[@coolhari2000]

I was wondering the same, guess they're allowing experimentals everywhere. I fully support it as they usually have better equipment these days.

[@wylesjs]

How effective is the heater at altitude?

[@romeodelta9484]

Nice. I flew sling 2 only to 6000 feet 😂

[@LTVoyager]

How well was the intake air temp controlled during the climb? I understand this is an issue with the 915 in many installations given the very low limit Rotax has set.

[@SlingPilotAcademy]

not a problem for us :)

[@LTVoyager]

Sling Pilot Academy Do you have data plots that show the intake temp during a range of operations? I am curious what you see on a hot day, say 90 degrees, during climb.

[@Captndarty]

@@LTVoyager nope because they know there’s an issue and they don’t want to talk about it

[@LTVoyager]

@@Captndarty Yes, I am sure they did not meet the initial intake air temp specification and just ignored it as did many others. However, the good news is that Rotax just released a new manual and this value has been dramatically increased from 120 to something like 180 so it should be easy to hit now. I suspect the initial value was a mistake, but who knows what Rotax was doing or thinking.

[@Skepilot]

@@Captndarty There's no issue. Max manifold temp is 80 °C (176 °F). Never comes close to that.

[@rcktpilot]

I know at 9500ft it does 145kts...the 915 critical altitude is 15000...what will it cruise at near that altitude?

[@SlingPilotAcademy]

You'll be cruising at around 150 to 155 KTAS at 15,000.

[@wstafco]

Are you frigging kidding me? The Sling can fly as high as 30k feet? Curious, how long could it maintain that ceiling?

[@coolhari2000]

If that's the ceiling, it can maintain it till it runs out of gas. I.e. If it can climb to am altitude it can stay there.

[@wstafco]

@@coolhari2000 thanks for the response. I am really impressed that it can fly that high. I guess it also would depend on turbulence at that level as well, since I presume it might not be able to deal with much of that.

@@MrMinefeld Thanks

[@thonatim5321]

DOWNVOTE: No Music

[@cloudstreets1396]

Somehow I doubt the Sling is RVSM compliant.

[@pilotavery]

RVSM compliant just guarantees you access to RVSM airspace. Controllers can still at their discretion allow any traffic into RVSM airspace. It's very rare that they did not access, but if they are extremely busy sometimes they will deny access to uncertified aircraft.

It’s a package deal. You can have lots of power, but it’s not much good without aerodynamic controls that are effective at that altitude.

[@SlingPilotAcademy]

You're right: Airframe, Prop' and Engine all have and impact. 915 does crush all previous models due to turbo, intercooler and injection!
