Leslie V12 liquid cooled 108cc Model Aero Engine

World First - Test Flight V12 Model Aero Engine - 1/5th scale Top Flite P51 ARF

[@crypkrazee]

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

[@biomechanique6874]

It also means the pilot is aware of the wing loading and didn't try a slow scale-like fly by. I have seen many fine looking scale planes stalled and destroyed that way.

[@monsieurcommissaire1628]

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

[@dr.wilfriedhitzler1885]

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

[@ThomasDoubting5]

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 .

[@malcolmcarter1726]

Me too! And its every bit as good as I always thought it would be. Now we need to genetically engineer a 1/4 scale pilot to fly it!

[@hartsfire5706]

that V12 sounds so good. sweet test flight.

[@bobsbillets]

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

[@mathiasderichbin2027]

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

[@LungsMcGee]

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.

[@glennandrews7689]

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 :)

[@alfabethev2.074]

Wonderful! Well done 👍🏻

[@rcs3030]

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.

[@hugejohnson5011]

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

[@michaelgay5541]

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

[@jonquinn11]

Definitely didn’t have that beautiful Merlin sound.

[@ThomasDoubting5]

The small model V12s don't sound particularly good the cylinders are tiny , It doesn't sound like a weed eater though ? and it's really under proped so it's much faster than when it's properly loaded with a decent propeller .

[@danw1955]

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!😉 (The speed control in YT won't do it, because it tries to maintain the original pitch)🙄

[@malcolmcarter1726]

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?

[@sunblock50plus999]

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

[@MJPilote]

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?

[@TheJustinJ]

Purchase an engine simulation software and start modeling, or just copy another basic cylinder and valves from a properly sized engine.

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

This toy if not respected will rip your hand off.

[@cal-native]

@@flightforensics4523 this aircraft is not a "toy" - it is the result of hundreds of hours of engineering and construction, and one of the first examples of an actual flying miniature V-12 that I'm aware of. The thought of a full scale, historic, multi-million dollar P-51 in the hands of someone with your childish attitude and arrogance is frightening, if true.

[@RCScaleAirplanes]

12 cylinder for 108cc can't make any good sound. 🤷🏻☹️

[@ThomasDoubting5]

​@@RCScaleAirplanes it's cylinders are 9 cc , to get a better sound I'd say you would need 25 to 100cc cylinders . I'm just buzzing a water cooled V12 has flown in war bird it's incredible and very exciting .

[@wyattboothby5285]

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!

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.

At around 1 1/4 miles range I think the standard gear will be fine.

​​​@@futabaproshopIt's not going to last long in that Airframe. I've watched it fly. The Airframe is too small for the engine. The risk of tip stalling is very high. The short test flight was very risky in itself..Is the small fuel tank a header tank from the main tank?...Or is this why the test flight was so short?...🤔😳😳. That's a WW2 fighter btw.

[@paulmoffat9306]

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.

[@superpela1]

No if you fly in your airfield club and is registered as a flying field for rc models

Can Canada effectively police their entire wilderness area? IIRC Wolverine came from a black project there.

In France, if you don't fly in a model club, you have to take an exam and register your plane, then add a 2.4GHz beacon. There are also areas where flying is prohibited, but there are still plenty of places where you can fly.
