When a maiden flight comes back in one piece, that is a Big success ! great job.

Bravo! A V12 model aero engine is finally with us. Don't let the nitpicking gigadorks bother you. You've achieved something amazing.

Some people are really hard-working men. Such a super cool engine and such a lot of work! Respect!

Wow wow wow , i knew someone would do it eventually , I've dreamed of seeing this since a little boy , This is ground breaking in the scale warbird arena . Absolutely buzzing thanks for sharing this .

that V12 sounds so good. sweet test flight.

Beautiful engine...no doubt! Just a friendly criticism: that landing approach was way, way, too steep! Your beautiful plane was building E on it's descent; not shedding it, hence the wild porpoising as you tried to flair. I'm a old timer RC flyer and real general aviation (single engine) pilot; your landing approach should really be at a much shallower angle to the threshold/runway and by all means, take your time to get out your flaps and gear and bleed off that speed!! I suggest you get gear out and flaps down as you turn down-wind from up-wind of the runway, pulling your power back to about 25% and maintaining a shallow descent on the down-wind approach. When you turn-to-base (L-turn to runway), make sure your throttle is only slightly open (~ 20%), coordinate rudder/aileron turn to final, and maintain a long, shallow approach to the field with power on. I see so many beautiful models pushing their gear through the wings, or worse, due to poor landing approach technique which manifests itself in porpoising, crashing through ground effect, etc. Let's keep you and that lovely plane flying for many day's to come!! Love to have one of those engines in my old 1/5th scale Pony as well..! Happy skies :)

That engine would be cool in a R/C boat or car too!

When it first started up I was thinking that sounds worse than my 3 cylinder Daihatsu van. But when it's going.... Holy guacamole, sounds great 👍👍 Well done, thanks for sharing.

Unbelievable! What a fine art of craftsmanship! That is so cool.

My all time favorite. Such a beautiful job. And a nice flight. So now before its.too late hang that beauty up. You and others will then enjoy it for many years to come.

Bruce from down under, demonstrating to, Bruce and Bruce the lovely v12 powered rc mustang. Gday.🤠👍

Too cool! I will be waiting to see it with the prop grabbing more air! It sounds so cool!

Wow! That really is something. Even the sound is scale. And it (the V 12) could power a multitude of types. Imagine a 1/4 scale Lancaster with 4 of those amazing V 12's overhead?

Beautiful plane and a successful flight well done 👏

Amazing. The miniature V-12 and the effort.

God,...some people have tooooo much time on their hands. Wow! I choose to live vicariously through you :)

Wonderful! I wish you'd do another video on just that amazing engine.

Wonderful! Well done 👍🏻

Incredible! Looking forward to more footage!

Awesome set up and maiden! Congrats!!!

Wonderful from Northern Utah 🇺🇸!!! Love It can't wait for more and one on the Engine Please!❤😊

Amazing work!

Lovely little engine.Just like a Swiss watch.looks beautiful❤👍!

What a beautiful model

Congratulations on that maiden flight!!!

Awesome! This scale model is even better than the real plane. The engine is gorgeous.

WOW! Holy bleep! that is spectacular! Subbed here.

You won't run out of power with a low pitch. Looked real scale speed too. Good job mate.

Well made , well done - well maiden flight! Enjoy your P51 ! The pitch is a good sign then you have made the motor right 😂

THAT is AMAZING!!! OH WAUW =) Congratz, it's a beatiful bird.

Love it, well done.

Not the sound i was expecting. Sounds like a regular weed eater engine. Extremely cool none the less.

Nicely done Sir

Thats amazing....super cool work gents

Well done!

How in the world could 4 people dislike this? It is fantastic!

Wow, you really BANGED that in didn't you fella???? .....Surprised you had ANY wheels left after that!

Wow, I would be way too intimidated to fly that work of art. Beautiful

Good on ya ! Thanks for sharing!

cool! keep us posted on the next flight with more pitch !

Congratulations for a successful maiden ❤😎🤙🏼

puuuh...that looked like a tailhavy fight ... good job

incredible!

Elegant maiden flight, no doubt

One of the most interesting set-up in Aeromodel I've seen in the past 10 years ! You could be very proud ! Definitely need a microphone to improve our pleasure in your video Cheers from France 🇨🇵

Thank you that was really nice 👍

What a plane! P51s are a favourite. Can you do an episode just on the motor?

A magnificent achievement. Well done to all.

Awesome sound 👍🏻🤗👍🏻🇺🇸🇺🇸

That's so awesome

How freakin' cool is that?!! A real scale model Merlin V-12 right where it should be in the P-51 warbird!! ..and it actually runs and flies! Can't wait to see it swinging a little bigger prop, better suited for the power curve of the engine.😄👍👍 *EDIT:* If you download the video and drop it into your favorite video player and drop the playback speed by 3X, that little Leslie V12 sounds identical to the RR Merlin at speed!🛩

You had me at "liquid cooled"

That is just straight up bad ass.

😮 awesome!

WOW AWESOME !!!!

A fat chunk of awesome.

Great work! Lovely noise too. Greetz from Holland.

Sounds awesome

sounds pretty dam real

I have the plans for an air-cooled V12 about that size in my files from a company out of Germany. After they completed that, they went on to do a liquid-cooled version.

Finally someone has done it what I have dreamed of doing, have partially machined crankcase and crank with rods on my shelf just to make a V12 on a rc mustang. Is there a build blog or something to get more details of this amazing build?

Impressive.

Fantastic 💪🏼💪🏼💪🏼💪🏼😎😎

Wonderful ❤

Fantastic.

That's a slick unit. Doubt I'd have the nerve to actually fly it considering the hours and money it represents. I think the most amazing feat of precision measuring and machining I have ever laid eyes on was at an RC and ultralight fly in I attended about 10 years ago with my Rotorway Scorpion 133 project (a sadly incomplete project). Anyway, I happened upon an old timer that always had something cool to show off every year. This year he had a huge BV 138 flying boat in gorgeous luftwaffe maritime patrol livery that be designed and built in his shop over a few years. looked to be about 1:10 scale and everything was accurate right down to the hand made rivets in the hull. It had a functional searchlight, turrets and retractable gear but that's not even the coolest part... This guy hand designed (no computer because he didn't know how to use one..) and built not 1, not 2 but 3 scale Junkers Jumo diesel aero engines! complete with hand built turbo's, gearboxes and props. And he did it the old fashioned way with lathe's, saws, drills, files, lost wax casting etc. Apparently he even built a mini drop hammer forge to make the rods, crank and studs. I was so amazed I forgot to ask the obvious.. What the hell does it run on?? At that scale I'd expect diesel to have a viscosity like motor oil, so I doubt it can be atomized through a teeny little injector.. They all ran great though, and it sounded amazing!

Cool.. gotta keep throttle a bit when landing.. never shut all the way down

That was awesome. The plane is beautiful. I love the sound of the engine. Do you have plans of adding more stickers to the plane body?

freaking wicked

Beautiful plane in building a P51B

Nice

Nice. Tell us more about the engine

Did not see whole video but thumbs up! Would be cool to see how they are cooling it. Total loss system?

I was expecting a more exotic sound from the engine

Will you ever fly it at warrnambool? Would be awesome to see fly.

Where is that amazing engine from???

right rudder, right rudder :)

Doesn’t quite have that Merlin sound but still sounds pretty awesome. Nice work!

That sound bravo

16kg for a top flite p51 is a lot a lot. Does the engine really need the additional weight of an onboard starter?

Wow, even Rolls-Royce would be impressed!

Where can you get that motor

Are these beautiful engines reliable? What kind of hours can you get out of one? Or can they self destruct at any time?😁

MINI MOTOR V12 👍👍 🇧🇷

Wow.

🤘

Sounds like it’s turning too many R’s. Definitely needs a hotter pitch prop as mentioned and possibly more gearing? Not sure what the optimum torque/hp spec is. Just the sound of it being v12 seems like it’s stretched waaaay out

Is that a 2 stroke or 4 stroke engine? Incredibly small components, if it's 4 stroke!

very cool, is that a real v12 engine?

Next project a Hawker Tempest with a scale Napier Sabre?!

Wow, great achievement. But Sadly, this sounds like my lawnmower .

are these engines available to purchase? I need one!

Beautiful but sound was disappointing

damn...

Sir, Do you sell these engines? If so, please give me contact info. Thanks

At that size and performance, a TBS long range FPV system might be a wise choice, that model could get too small to orient by visual aquity alone very very quickly.

BRAVO- wonderful model ! Sadly, here in Canada, I would not be able to fly such an aircraft - reason being, the Canadian Government has decided that ALL RC Aircraft models over 200g are potential, weaponized drones! All such RC models, need to get an aircraft REGISTRATION, have a TRANSPONDER, have the SAME log books as a real aircraft (engine log, airframe log etc), and the operator have a 'Drone Operator License'! It is now illegal for me to fly my B25 Mitchell Bomber (Royal Kit). That effectively has killed this hobby.

Yeah right a 12 cylinder micro engine.

Gorgeous engine........but put that on gasoline and get away from the glow fuel!!!!!

V12 Or Not These Engines Are Not Strong Enough! Check The German Record "The Galloping Ghost P-51" They Used A Self Made Inline 4 With Breathtaking Power Speed And Sound....
