XXL EXTRA 330S Wankel Engine 

That engine sounds amazing! It's like a mini Merlin when heard from head on, but then when heard from the rear, it sounds like a two-stroke!

Absolutely FANTASTIC. What a plane, what an engine, amazing job from the owner, big respect. Love it! Thanks for the video!

Merry Christmas. Thank you for all the nice videos you share with us :-)

A beautiful plane that sounds delicious. Excellent work on the camera Horst, *thumbs up!* 👍 👍 Cheers, Bob

It looks so real! you could have people standing far enough back on the background to adjust their relative size and have some really convincing photos

Totally beautiful plane wow amazing flying too Excellent job..thank you..

Couple more of them and you could have a RED BULL air race! Beautiful 330, and an excellent demonstration of talent in flying. Thanks for sharing Horst! Merry Christmas!

Grazie David and Horst, almost as full-size !!!

Amazing! Nice flying and Amazing Extra300

You can always tell the sound of a wankel engine. Plenty of power, torque, and noise. Great video.

So COOL. Best looking RC airplane I've ever had the pleasure to see and hear. Thank You for your excellence. Very well done. The paint job is awesome too, as well all the rest of it.

WOW, what an AWESOME bird, thanks for the great video!!!

Beautiful looking plane! You should be proud..

Such a cool sounding engine. Well flown too.

Such an amazing plane and sound. Just lovely

Best camera work if seen for awhile! Good job

It's so smooth and precise

That is one superb plane - BIG! Plenty of power... very nice flight. Season's greetings Horst and thanks for all your great videos.

OMG! What a BEAUTIFUL aircraft! The only negative thing I can come up with , it isn't mine!! FANTASTIC FLYING and a magnificent c

That thing starts so easily .. nice sound too

That was spacial good job!,

that sounds brilliant!!!!! like half a mazda 13B twinrotor

Great plane, thanks for sharing :)

In the 1960ties... you'd expect 30Hp in a car... smal or pré war... Very nice plane! Well flown!

Beautiful prop 😮😍

Bonjour Horst, The sound is also XXL, wonderful ! We were spoiled by your quality videos this year, hoping that continuous. Nice Christmas time cheers Horst, Christian.

Great Aircraft with beautiful sound 😎😎👍

Beautiful paint scheme and very nice build

I like the scale looking Prop, holy moly. excactly what i like on the ground

Excellent, Bravo!

Nice colour scheme, looks the part.

Nice landing

Merry Christmas & Happy New 2018! Horst!

Oh she sounds so sweet! very nice!

Beautifull, i would love to see the engine please?

Super ! un joli modèle et d'un vol vraiment très réaliste, bravo pour cette réalisation, et joyeux Noël...

Flown with a great deal of skill and confidence. You have both my respect and envy. AMA 8855

Это классно!Пилотаж как у настоящего,правдоподобный,а не как у 3д.Приятно смотреть.Браво пилоту мастеру!

Hi Horst, Thks!! BIGGER!!

It almost starts itself. That is a beautiful setup.

My ... My ... My ... ! What a great and fantastic aerial flight display and maneuvers on this extra large RC piston driven aircraft and really looking forward for more of this aerial flight displays doo on your next channel on RU-vid soon again. Thanks so much. Regards. From The Flight Deck

I was like. "a Wankel" wtf Then I was like. Damn "a Wankel" No shortage of power in that plane. Beautiful flight!

so smooth

Ciao ragazzi molto bene ho amato quel piano molte congratulazioni e un grande saluto a tutti da Buenos Aires 😃👍👍.

You know I have a question. Often with the giant scale videos the pilots take off on the paved portion but land in the grass. Is there any particular reason for that.

Wow, must be some process to scratch build and certify such a beast! Big thumbs up!

very beautiful friend

Would like to see the engine on it

those knife edges, that engine was dialed in and running pretty good....

Absolutely flawless build, but I agree with Justin (see below)-the way he prop starts the engine without any obvious means of preventing the plane from moving forward is really alarming. Beautiful landing, not sure why some are criticizing his flying.

Very Cool Plain

SUPER reales..FANTASTICOS!!!!

Tolles Modell, tolle Kamera Führung. Da macht Video sehen Spaß

Great flight...but all the popping, banging and misfire?? sounds would have me worried. I hope it’s ok,

great performcae big like

O som deste motor é fantástico!..👍👍😵

Gorgeous plane

Beautiful!

Amazing build. How was it shaped? 3D printed molds? Slightly different shape and a person could fit in it. Wouldn't need to be bigger. Something to think about.

Nice sound

Beautiful job on the build! It looks about the same size as my Godfrey 40% Extra300. 😉👍🏼 Sounds like the engine is missing on a cylinder or something at times. 😬 GREAT job behind the camera as ALWAYS my friend!!! Merry CHRISTmas to ya my friend!!!

What a sound.

Grat build and flight. But way the engines sound like misfire some times?

ROTARY!! Nice!!!! Now the RX-7 wants to fly, too!!

Bravo!

I come from that Moki fired historically-correct-fraction but this thing kicks ass

A nice small model!!!😜

Шикарная раскраска.👍

Boah... der Sound ist ja mal außerirdisch.. nicht dieses Einheits-Boxer-Geplärre, sondern mal echt was exotisches.. ich war überrascht, wie schnell sich das Ding anwerfen lies.. Riesenvogel mit Exo-Antrieb.. Vielen Dank Horst, das war das erste Highlight am ersten Urlaubstag :-)

Wow, Wankel engine, where did he finds that? Old NSU car?

Awesome 👏👏👏👏

What Wankel engine are you using?

Deffinatly different sound. It likes to run.quite responsive

Eat your heart out, Waldo Pepper! This guy is a true hot dog pilot!

That engine needs to be a warbird, say a Bearcat, sounds great!

That would be me... if I had money. : P I started out, and learned on large scale. First heli was a HK600. First plane was a 1300mm mustang. In my opinion, large scale is far easier to fly.

Any bigger and the pilot could get in it himself. Impressive, very impressive.

Wonder why these builders don't try their hand at building full size aircraft?

Thumbs up bro :-)

sounds like its sputtering every once in a awhile ??

Good thing that nothing happened when he started the engine. Otherwise, it would've messed him up. Always have someone standing on the tail.

75 kg???

holy! 1/2 scale wow

hope it plows in!!

Fagagna (UD) Italia. Grazie per la condivisione!

That thing has near vertical take-off!!

Could you hover this plane under this power?

super!!!

Hallo lieber Horst, das Beste ist wie immer Deine exzellente Kameraführung! An den Sound des Motors kann ich mich nicht gewöhnen, egal. Geschmacksache. An den Startvorgang des Kollegen aber nicht. Echt leichtsinnig. Gut, dass nichts passiert ist, sonst wäre Dein schönes Video als Beweisaufnahme bei der Versicherung gelandet. Wünsche Dir eine schöne Weihnachtszeit und freue mich auch im neuen Jahr auf Deine Videos. Viele Grüße, Markus

Nice backfire

Two rotors or just one?

Excellent video it almost seems like the engine was loading up a little bit on the dive at first but after a couple of passes it started ringing out and then I thought THIS sounds ALMOST like the full size extra lol definitely a beast

*RX7 VIBES ON*

What engine is that??

wich the price of this model? +-

I want one! Now!!!!!

That's the trouble with Wankels,, they're so hard to start. :*)

Impressiv plane and building!!!!
