Just a fun, non-scientific comparison between the Prestige 2PK and the GCM Vertigo. Not using the motor at all and looking at the turning and landing characteristics of each model.
Both of these models are about 41 oz or 1170 grams. Both have same 4 meter wingspan and similar wing area.

Never saw such seemingly easy glides. Forget the heavy radio it could be called a sort of art. A school for perfection. .. Real birds may be jealous !
Thanks for sharing.
What Is Islam?
Islam is not just another religion.
It is the same message preached by Moses, Jesus and Abraham.
Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
It reminds us that since God created us, no one should be worshipped except God alone.
It also teaches that God is nothing like a human being or like anything that we can imagine.
The concept of God is summarized in the Quran as:
{ “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)
Becoming a Muslim is not turning your back to Jesus.
Rather it’s going back to the original teachings of Jesus and obeying him
@@ahmdabdallah5811 I disagree about almost every points but I will answer more longly later.
Evangiles, life of Jesus, is worthy ('rather'). Isaïe too. God beeing one has been very well told by very old hindu vedas, 5 000 years ago.
Regarding laws and teaches did you read «The Prophet» by Khalil Gibran ?
@@ahmdabdallah5811 I respect your desire of divine, mystic life, truth, justice, love...
I've never flown RC anything, but those look like great fun. They are really beautiful to watch.
Talk about a dream bird. Those are beautiful good sir, amazing looking workmanship.
You don't build a competition bird like that, you buy it. Upwards of $2K

awesome gliders, these wingspans stretch globally, cant say the same with my micro gliders. well done and love the color scheme

Nice Flying Ali on Hand Toss flying. Thanks
nice video, with a very detailed comparison.
Concerning the ease of spiralling the Vertigo, maybe it's because of the wing joiners that have too much dihedral (if you use 7 degrees). Indeed, I have done tests with f3j gliders and found that gliders with too high dihedral turn less well than the same glider with a lower dihedral. Of course this depends on the wing profile etc.
P.S: The Vertigo climbs faster in thermals because its wing profile is thicker. However, it will need more ballast in the wind (this is a theoretical study, therefore not necessarily true but it is based on well-founded physics principles).
Марк Дрела конечно известный и заслуженный ученый , но общая геометрия мне не нравится ни на первом , ни втором самолете . Опыт мне подсказывает что в ближайшее время этот класс моделей будет выглядеть совсем по другому
@@vsn-po7zq I don't know if I understood your message very well. Sorry my Russian is not as good as my English or French.
If I understood correctly you didn't like the 2 gliders? If yes, why? They both have advantages and disadvantages.
For my part I don't think the future f5j gliders will change drastically. Indeed, we are already at the limits of the weight/strength ratio so the construction will not be much improved. For the design, the physics limits the possibilities a lot and I think that the current wing profiles are already at the maximum of the possibilities. The various improvements that could be made are the addition of BEC as on the el nino but this adds a lot of drag to the model.
I hope I understood your message.
we can contact by e-mail or messangers , please write
@@gaderyfr8485 ok, i will contact you

Wish I could fly like you! Awesome and thanks. Good time to be flying

Winches are for wimps! Is this how good technology has gotten? Being able to speck a plane that size from handlaunch! Impressed with both planes and the pilot.
From a hand launch if I didn't see it I would not have believed it. No wonder they cost so much. Nice thermal detection though.
Incredibly light for the size.
Cool! Flying with a Handlaunch.....
To be honest - this comparison relies too much on the availability of thermals at the time of launch and in the direction the model was thrown. As mentioned it would show the difference in ease of handling though, as mentioned.
Was just looking, these high end planes sell for over $2,200! each
Thats amazing bro, but may i know what changed when fly mode changed to "thermal 1" or "thermal 2" ?
Increased wing camber. Dropping the ailerons and flaps.
@@flightcomp how to increase the altitude of the plane?, And do you have social media?
with a very detailed comparison. 💯👋👋👍🤙
It would be great if you could talk through you launch and flight modes and narrate the flying a bit.
Interesting, I can try that.
Great plane but im still addicted to powered flight, i like to fly in more than circles lol
I dabble with power and heli's fairly often.
the first one was using the hill for lift.?
The Vertigo looks like it’s more coordinated in a turn. You might be able to muscle the prestige around more but it didn’t look as coordinated and that’s more “draggy”
Very nice comparison Ali, thanks for sharing. Curious what Vertigo joiners you were using. 5 or 7 degrees?
I use the highest angle joiners 99% of the time.
Nice Video, Ali ;-)
Thanks for your videos , are these gliders good to start with for beginner?
Beautiful planes and flying. Why are you afraid to hand catch the Vertigo but not the Prestige?
What if you launched from a place with some tarmac, like a parking lot nearby... Wouldn't the tarmac generate enough heat to create the thermal lift you are seeking?

Prestige have better turning and overal handling for me by video. maybe it help to use more rudder in turning for Vertigo.
I noticed the Vertigo was a little quieter on the fly by. Were you in the same flight mode during the pass for both gliders?
i would like to see vertigo vs prestige vs optimus sport bf
Insane models, mind blown 👍
Great!
My highly subjective observation is that based on the audible difference in the speed passes, the Vertigo is either cleaner aerodynamically or better sealed.
Is the term camber essentially a flap setting? Landing the Vertigo, it appeared there was a generous amount of landing flap, perhaps 25 degrees? I wonder if the Vertigo perhaps gives up some amount of positive dynamic stability relative to the Prestige, thereby accounting for the handling differences you observed.
First generation 15m SH Ventuses had neutral dynamic stability, but were superior in performance to ASW-20’s which were more stable. SH corrected this in the V2. Schleicher has stuck with simple dihedral whereas SH and others have adopted more complex polyhedral configurations.

3 minute flight from a handlaunch????
how is this possible? anti matter infused carbon fibre weave?

Thermal
flat field thermals brother.....its the preferred method for the thinking man /woman.... The fly fishing of the gliding world. :)
Hey, just interested in what controls you use low level like this to 1. Establish the bank/turn and then 2. To maintain the turn. I guess I'm trying to find out if you are mostly using rudder or aileron in these low level thermal turns.
I have about 40% rudder mixed to ailerons. However I use the rudder stick a great deal. Initial bank is with ailerons then I use the rudder stick to try and keep the fuselage level through the turns.
@@flightcomp thanks for that! So once you're in the turn you are using inward rudder to maintain the turn and outward aileron to stop over banking?
Very nice! 👏👏👏 F3K-X 😅
how would these birds compare to the Pulsar gliders from esprit tech?
I have Prestige 2PK and Vertigo F5j Poland. Honestly Vertigo is better 👍.
Just on a hand launch can you get it on a ridge and asscend?
No ridge, thermal lift.
magico
What was the breeze direction here?
Very light breeze, shifting directions constantly. Most likely due to thermal activity.
I tell u you were throwin them hailmarys tho.
я нихрена не понимаю как оно так долго летит и без мотора!! но это впечатляет! хочу такой же.

Oooooooooooooo Yeeeeeeeeeeeeeeeeee 🤘 beautiful birds, I wish I could buy it once or maybe someone give it as a gift 😊🤞🤷♀️😜
I just so bad would like to build a real motorglider and ride ridges.
DONT FLY THAT NARROW CIRCLES - - -OMG - -- - AND ONLY 2 min FLYING - TIME ? - - -ARE YOU REALLY A GLIDER - PILOT ?
OMG...no I'm not, I'm a terrible pilot.
@@flightcomp Hahahahahaha.... NOT SO!!
Oh, relax, Micha. He's having a huge amount of fun mucking about with hand-launches and hardly killing anybody at all. He's over-flying because this is a comparison video, not a competition. He's landing early to keep the video moving. Judging by the conditions he could just as easily have been flying a speck in the sky for 45 minutes.
Would you still have been watching?
I would. I love to 'see' the air at work.
