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!

[@RCScaleAirplanes]

_Thank you for your kind comment, which I really appreciate._ 👍😉

[@mr.y1965]

Exactly

[@jumpingjacks5558]

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

[@RCScaleAirplanes]

Thank you for the compliment which I really appreciate. Glad you enjoyed it!

[@abcdef-cf2uk]

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

very beautiful friend

[@1980VINZ]

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

[@bobdyer422]

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!

[@ferdorski]

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

[@stacyp4534]

It almost starts itself. That is a beautiful setup.

_Thank you for your kind comment._ Yes ... that engine is awesome! 👍😉

Is that an actual RC engine or is it like a snowmobile or motorcycle engine

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

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

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 KZbin soon again. Thanks so much. Regards. From The Flight Deck

[@RCScaleAirplanes]

_Thank you for your great comment!_ 👍 Since the pilot lives in another country, which is 500 miles away from me, it will be difficult to catch him again for another video. *Here is another flight from 2018 >>>* kzbin.info/www/bejne/oImueYJ3dsZkfqc

Such an amazing plane and sound. Just lovely

[@lateuerjackson]

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

[@islander4986]

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.

[@RCScaleAirplanes]

Thank you for your kind comment. Much appreciated !!! 👍 I fully agree about how he started the engine ... it's an absolute *NO GO*

[@joeadame1069]

Amazing! Nice flying and Amazing Extra300

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

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 :-)

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

[@frankmoser6251]

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

[@FlyingAce39]

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

[@jonkje]

Justin Owen my first thought as well...

[@benjaminlann]

Agree with you. He appears to be a novice. Pretty nervous flier, engine doesn't sound like it is tuned either.

[@loud_n_lowtaco200]

[@ferrarikingdom]

at this scale I imagine the brakes are pretty significant

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!!!

[@DailyWarbird]

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

[@RCScaleAirplanes]

Speedfreak NZ _Good idea. That would be awesome._ Thank you for watching and commenting.

[@psygn0sis]

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.

Because they don’t have to worry about all the FAA crap.........oh wait...

Scratch build full size guys doing that over on www.biplaneforum.com/ lot of them are 10 year or longer projects. Or this skybolt first flight kzbin.info/www/bejne/o2axkJyHerx9qsU

[@markgamble8377]

Deffinatly different sound. It likes to run.quite responsive

[@maxmorgan2297]

The only reason all cars don't have Wankel , is the fuel consumption and a "small" motor renovation around each 40.000-50.000 Km. (Mazda rx-7) The power and ""all the way" moment is really strong.

[@JoeSmith-zg7in]

What a sound.

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

[@jamesbonde4470]

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

[@darrendix5163]

Oh WOW! Only thing I would say to do better is put a Moki 400cc 5 cyl. in that.... I can only imagine how awesome 1/2 scale must be, though! I used to fly a 1/4 scale P-40 with a Genoah G-38 in it, and that thing was just as reliable as the real thing. I fly a friend's P-40, it wasn't mine, but he trusted me not to crash it. It was a piece of cake to fly compared to tiny 48" wingspan models with glow engines, although I had those down also at the time, only ever having incidences with radio interference at the time with an AM radio. I'm sure today's radios are much better... (this was in the late 80's mind you....) AWESOME plane!
