NO WAY! Unpressurized Sling TSi Airplane gets to 27,000'? (PART 2)

[@tonym3675]

27000 =5.1 MILES UP THERE. WoW! And they did it heavy (indicated in part 1 on take off) and all VFR rules. . Do not try this in a sling TSI unless you are a VERY VERY experienced Pilot. Even then, don't try it alone. Have someone with you. Preferably another experienced pilot. But a great video to show and prove what a Sling TSI can do it. Great job guys. It's not the norm. Listed ceiling for a TSI with the Rotex 915is is 18,000 ft (3.4mi}. That should be high enough for most, in a plane such of the likes of the Sling and others in it's class. Now if I wasn't 63 years old and had the money, I'd be right there buying a sling. But as it is for sooooo many. Money is the issue and not so much age.

Wow -- 15 minutes in, you caught Kevin Thornton on the radio (N771BC -- "310 Pilot"). Way to Go!

[@gtm624]

That was not 310 pilot call sign. Listen carefully to the first call which reads the full call sign. But to even have caught the last 3 you must be a huge fan of his channel. Lol.

[@andrewstoakes1365]

Thats a significant pair of ball, taking the SLI to 27000...Well done gents!

[@maesc2001]

You were a little nervous? I was a little nervous; damn!

[@pilotjim4595]

I got light-headed just watching.

[@worldaviationnetwork]

Such an amazing machine!!

[@funpilot2]

Do you have performance numbers for 17,500, 25,000, and 27,000? Indicated, true, fuel burn, etc? I own a TTx and Tecnam LSA and I've been on the verge of building a Sling since the 915. Mojogrip, I'd love to talk with you one day. PM me.

[@pilotavery]

At 25,000 ft it burns 6 gallons per hour at 154 knots true airspeed and climbs at 405 ft per minute

[@Captndarty]

I sure hope that the pilot was instrument rated because it sounds like when they re-cleared you direct to Oshkosh and FL 230 that was an IFR clearance. That being said if you were instrument rated why in the hell wouldn’t you have done it from the beginning negating all the trouble you gave the controller and yourself for the VFR transition.

[@gtm624]

The did not file a flight plan. There is no vfr above 18,000.

[@cw2818]

The 915IS is an impressive engine. The Sling TSI performance is equally impressive. Do you think the only endurance issues for flights between FL18 to 25 are human physiology?

[@sactu1]

Well done guys!

[@mindrelic]

*checks oxygen levels* "am i meant to be breathing?" lmao

[@aircraftpartner2695]

What engine type? How was the temps with the thinner air and long climb? What was your TAS after leveling off?

[@arjunsinghyadav4273]

It’s 915is, TAS I think they said 120knots, since it’s liquid cooled thinner air is not a problem

[@flywithandee]

Wow!!

[@mdkrapf]

Is there a anti icing system compatible with the Sling TSI?

[@pilotavery]

Therm-x but you'd need to do it custom.

[@johndonald3566]

Cool experiment but let's leave it at that. No place for an aerie like that.

[@Rico11b]

WHY, WHY, WHY are airplane designers and builders continuing to build copy cat aircraft designs. This design is almost identical to dozens of other planes that are just copies themselves. WHY, WHY, WHY do you continue to seat the pilot on top of or behind the wings. Seat them in front of the leading edge for a much cleaner all around view. And don't say it can't be done, because I can point to many designs where it is done, and also with the engine mounted to the front. Cessnas are perfect for viewing below while flying but you can't see upward at all. Pipers and Mooneys are perfect for viewing upward and outward, but you can't see downward because the wings block most of the downward views. Put the pilot in front of the wing and you have both. The Diamond DA-40 comes the closest that I've seen so far.

[@gtm624]

What do you fly? What have you built? Armchair……..

[@pilotavery]

Because airplanes have been optimized over the years. If you put the pilot in front of the wing then that means that the weight of the pilot and how many pilots severely affects your weight and balance. This means that the more weight you put up front you have to get extra weights to mount in the back every time you change how many pilots you have. So the pilots need to be as close to the wing as possible for balance reasons. The airplanes have already been designed to be as stable as possible over the years and have been perfected. Any change they make just makes it worse.

[@pilotavery]

The DA-40 actually has the wing in the same position relative to the pilots, the difference is that it's a smaller and lighter plane and has a higher aspect ratio wing. It also costs a lot more.
