microlight world altitude record 2

[@mainairmark]

Oh I'm so sorry about the quality of the video, but then again I did it for me and not you :-)

[@mainairmark]

Hi, The official height was 24,262 ft which was a new world altitude record in a 2 seat flex wing microlight.

[@gliderfs621]

Serge Zin set an altitude record of 9720 meters at Saint Aubin, 1994, and this record is official.

[@mainairmark]

@@gliderfs621 maybe, but this was, as I said above a "2 seat flexwing microlight' record, and if you check it was an official world record. The record you will be referring to will be a solo "single seat' record.

Beautiful view of Mt. Kilimanjaro! Thanks for the ride. Well done!

[@markjackson700]

Cheers

[@mainairmark]

The person in the back is Eve Jackson, SHE was the first person to fly a microlight from the UK to Australia in the 80's. She also flew her microlight to Tanzania where she lives and works now.

[@cjgreen3836]

Well done chaps. I thoroughly enjoyed watching your glory :)

[@markjackson700]

Thank you :-)

[@darrellcook8253]

Someone needs a pressure suit with heat. That made my fingers cold just watching this. Phenomenal. Outstanding and a little bit of crazy. Well done! Ignore negative comments.

[@paullee0123]

“If you kiss me I’ll punch you” lol. A very well done and you’ve raised the bar in the Microlighting world.

[@AVMamfortas]

Great photography. Great achievement.

[@penmaker1968]

Fabulous video, Sir, well done! Thanks for sharing it with us.

[@markjackson700]

Thank you

[@michaelbailey8729]

Eve bless her. What a hero. Quietly putting up with a frozen mask.

[@deplorabledave1048]

I didnt know down suits that thick existed. Not much in the way of HAND protection, though... Did look VERY cold!

[@markjackson700]

They are standard mountaineering suits. The orange one is North Face. Because the air was dry, it didn't feel too bad. It was about -10c

[@Leyenda1]

I ask because I love all things aircraft or flying. It is similar in the way that the aircraft you both flew aren't conventional. BTW how did you change the fuel mixture or can you on a ultralight?

[@mainairmark]

I did think of it, but I just seem to be too busy. I am an instructor and if Im not flying Im fixing or doing something else.

[@mainairmark]

The engine is a Rotax 914 which is a Turbo charged engine. The carbs were set for altitude and so it under performed at low level and as we climbed it produced more power. Obviously as we get higher still it starts loosing power again until we can't climb anymore.

[@Leyenda1]

A remarkable achievement! Have you considered getting Red Bull to sponsor you to fly over the world's mountains? Something to consider...

[@markjackson700]

[@GotGame4me]

Did you have any problems with ice?

[@mainairmark]

No problems with carb ice or airframe ice. The temp was about -15C but the air is very dry.

[@AndreLuiz-ip3fh]

Yeah, I think, the turbo keeps the carb from freezing. Am I right?

[@itsjavaman]

That 5 degrees F. So not terribly cold but there's no oxygen and the air is thin. Pretty darn Amazing. Bravo!

[@markjackson700]

@@itsjavaman Thankyou

3:25 deflating fart marks new world record

[@sailboatbob3969]

what type of engine was used? to go up to 34,000 ft? and I'm surprised the wing didn't stall that high.

[@markjackson700]

The engine used at 34,000ft was a 3 cylinder 2 stroke Robin or Hirth engine.

[@ConvairDart106]

Would have been nice to share some of the view, instead of focusing on yourself 100% of the time.

[@sammey1919]

Which one of you is the most insane?

[@itsjavaman]

Would love to see this from start to finish

[@markjackson700]

All 3 videos are on here.

[@Leyenda1]

Didn't Bear Grylls do something similar to this over Mt. Everest?

[@derekwall200]

how high up did they go? did they actually reach 20,000ft? if so what kind of engine was on the trike?

[@droceretik]

+derek wall 24,262

[@derekwall200]

droceretik whoa. I never thought a trike can reach that altitude, was the engine they had on that thing modified? if so how?

[@droceretik]

+derek wall A Rotax 914 aircraft engine. I don't think it was modified apart from carburetor jetting. It is a horizontally opposed, 4 cylinder, turbocharged, 4 stroke, petrol engine commonly used in ultralights. According to the pilot the dual carburetors were re-jetted for high altitude so the engine was producing less power than usual on take off (mixture lean). It's capacity is a little over 1200 cc and it's power output is 73 kw continuous with bursts of 84 kw at 5,800 rpm for a maximum of five minutes. It is designed to run continuously at around 5,000 rpm I guess to produce 73 kw which maximises efficiency and minimise fuel consumption. It wouldn't have been producing anywhere near this power at 24,000 ft due to the air density of about 35% of sea level. Anyway, probably less than half take off power despite re-jetting. Without re-jetting this ultralight probably wouldn't have gone beyond 20,000 ft. It is a relatively unsophisticated engine with over head valves and push rods but it is built for reliability and to produce high specific torque and power within the intended rpm and thrust of the propeller. There is an integrated reduction gear ratio of about 1:2.7 according to Rotax specs. As is usual light aircraft practice, it has twin ignition systems (electronic) for fail safe. it uses low octane gasoline. I wonder if it can use e10 or higher ethanol percentage fuels.

[@derekwall200]

droceretik nice, after all a stock trike engine wouldn't be able to breath or provide the thrust needed when you're almost 5 or 6 miles high

[@derekwall200]

what altitude does the air start to get cold? I know you need O2 past 10,000-12,000 feet and I know at 24,262 feet air temp is around -20 to -35 degrees F

[@MrThundermouth]

A few screws some pipes....some bedsheets. Im gonna build myself a flying trike

[@johnnybumpous6484]

the engine has to be EFI don't you think ?

[@markjackson700]

It is a twin carb, turbo charged engine. No fuel injection.

[@markjackson700]

The engine is a Rotax 914, which is a 115hp turbo charged engine with carburettors, not EFI.

[@Leyenda1]

He did ...but it was in a power glider.

[@gaberth]

Im impressed... A QuicK Right ? Actually what is the Altitude Record in a TRIKE ?

[@gliderfs621]

9720 meters by Serge Zin in 1994, at Saint Aubin.

[@GotGame4me]

WOW!

[@mainairmark]

Well then that is not similar to what we did, unless the connection is we both flew near a mountain. Why do you ask?

[@jasosmurray137]

I know that has to be cold

[@carlhopkinson]

I wouldn't be so cavalier if I were them....they are in the death zone, after all.

[@markjackson700]

Cavalier? Death zone?

[@goodkarma33]

Not a word on the altitude. What was it?

[@markjackson700]

After calibration it was officially 24,262 ft

[@rathwije1579]

24,262Ft.Well done.

[@tumba35]

god job gents..congratilatons..

[@GregorioBarros]

A QUE ALTITUDE FOI

Errrrrrrrrrrrrr no.
