Only one way to describe this plane. BADASS.

[@RCPLANEVIDEOS]

😅👍 many thanks

[@lyallrobertson9761]

That's a fabulous model!! What a sound.. One of the best I've seen

[@RCPLANEVIDEOS]

many many thanks!

[@rcdogmanduh4440]

Wow didnt think it could have gotten any better! Great job.

[@RCPLANEVIDEOS]

many thanks ;-)

[@herbertmayerle6704]

Wow,toller Sound und schön geflogen :-)

[@RCPLANEVIDEOS]

vielen Dank ;-)

[@mrvoyagerm]

Perfect! I think the pilot was breathing better this time as well!

[@RCPLANEVIDEOS]

thank you ;-)

[@mrvoyagerm]

I know, I have been chasing gremlins in my new spitfire for the past 3 flights. All ended in a dead stick. I am hoping that I have the problem solved (tank vent squashed) and we can get on with just flying for a change. The farmer will soon run out of corn field for me to land on so I hope that was it! :)

[@RCPLANEVIDEOS]

oh my god --- wish you good luck and good flights

[@gabriele2108]

Nice piace of work! And good pilot too!!!

Outstanding sound! ...made that beautiful Spit even better, nicely done!

thank you very much 👍🤗

I needed this video to get me motivated

[@RCPLANEVIDEOS]

good luck ☺️😅👍👍

[@heliharris69]

Fantastic... But very loud even with a muffler.

[@RCPLANEVIDEOS]

thanks, and not loud, 76dB (-25m) is super 👍👍👍

Some day they will put a real Miniaturized Merlin V12 in oneof these giant scale RC's, it's comming!

[@johnbenson8372]

have followed previous videos of this plane. Some class fabrication work well done,electric start woube the next progression if room permits inside the cowl excellenent work all told

[@RCPLANEVIDEOS]

Thank you - i think, the engine sounds now really good ;-) Electric starter I would not, that would be again ~500g in the model and I have also no more space. He jumps but very well, 2-3x turn and he runs!

[@MrPowerup2010]

Omg That sound!!! Like those F3As

[@iggi70]

What are your temperature before and after? I see you installed temp sensors on the cylinders.

[@RCPLANEVIDEOS]

without sensors, it is not because you have no control over the engine. I have 4 sensores on the engine. basically it is the same, 125-135° on the inlet side and 150-160 ° on the outlet side from the cylinder. On the day it had 31° and I flew with a lot of full throttle.

[@iggi70]

Wow, temps looking good. Ever think of putting in water cooling? Maybe invent something very small like cpu water cooling? That would be the next stage in Big RC airplanes.

[@RCPLANEVIDEOS]

no, these are air-cooled engines and it works. Water would be too expensive. Then you have more weight and electronics ... no one needs that ;-)

[@brycekat]

What material was used to manufacture the exhaust system? Silver solder, brazing rod?

[@RCPLANEVIDEOS]

yes, with silver solder ...

[@brycekat]

Thanks! Nice setup👍🏻👍🏻

[@malakiblunt]

I was worried when I read muffler. But it sounds sweet

[@RCPLANEVIDEOS]

@@malakiblunt There had to be a muffler, without it it's just too loud 🙄😬

[@RupertatNutwood]

What prop is it, please? What rpm range do you get?

[@RCPLANEVIDEOS]

all infos find you in the KZbin video description 😉

[@charliem.9998]

bekommt so ein Teil einen Eintrag in den Lärmpass? :-)

[@RCPLANEVIDEOS]

Ja, warum nicht? Entscheidung ist ja auch mit was der Flugplatz für Lärmwerte haben darf, auf einen wo nur 70dB oder so hat wirds natürlich nix. Wennst dir die Videobeschreibung ansiehst findest sogar meine Lärmwerte 😉

[@leinadtoorg]

Toller sound! Hast du mit dem Setup einen Lärmpass bekommen? Wir dürfen nicht mehr wie 82db am Platz fliegen! Gruß Daniel

[@RCPLANEVIDEOS]

Vielen Dank. Lärmpass bekommst immer in erster Linie, is dann nur eine Frage für welche Plätze es reicht. Zum Spaß haben wir das hier nicht gemacht, es war schon gefühlt echt zu laut und dieses geplatsche von den Flammrohren kannst ja auf dauer nicht anhören. In der Video Beschreibung stehen die dB Werte, wir messen auf 25m. Jetzt hab ich umgestellt auf 26,9" Blätter und kann mehr Steigung fliegen, geht richtig gut. Das schreien vom Prop. ist jetzt weg und sie hört sich noch angenehmer an.

[@plumtube01]

Amazing aircraft, and very beautifully built, but are the gloves going to do much haha?

[@RCPLANEVIDEOS]

Thank you - and yes, the gloves cut into the fingers, these blades are very sharp 😉

[@galdramadur1]

@@RCPLANEVIDEOS Leckoboll, ja dran ist der schon.😂 Wenn du mt der Kiste auf unserem Platz starten würdest, dann hätten die Altvorderen unseres Vereins mind. 1 Std. Schnappatmung. Trotzdem super gemacht. Hört sich vor allem auf dem Boden richtig scale an und in der Luft hat der Kolm ganz schön Dampf. Hast du kein Problem mit der Kühlung des hinteren Zylinders?

[@RCPLANEVIDEOS]

die hat jetzt 76dB auf 25m mit dem Dämpfer, seit letzten Jahr flieg ich einen SEP Prop, da pendelt sie bei 75-76dB, also alles im grünen Bereich auf unseren Plätzen (teilweise bis 83dB Zulassung). Muss aber sagen, die flieg ich relativ selten bzw. mehr auf Flugtagen. Etwas mit Hirn fliegen, wie bei großen Turbinen, da muss man auch ned Sonntag früh starten. Kühlung funktioniert perfekt nach einigen Nachbesserungen, da kannst auch bei über 30° fliegen und rumheizen 😊

[@galdramadur1]

@@RCPLANEVIDEOS 76 db ist ja völlig in Ordnung. Hört sich halt im Video viel lauter an. Wir haben leider nur ein Zulassung bis 81 db aber da kommen die Wenigsten dran. Die meisten Maschinen mit Benzinmotoren liegen bei uns auch so zwischen 74 und 78db Dann viel Spass, wird langsam Zeit, dass das Wetter besser wird und es endlich wieder losgehen kann.

[@RCPLANEVIDEOS]

Ja, wird Zeit das es wieder los geht ... Pause war wieder lang genug ☺️😅

Una pregunta cuanto tiene de largo la pista 👍

[@vicyboy12]

Do you recommend this engine? For Cy model P47 96"

[@RCPLANEVIDEOS]

No, P47 has a round hood, so you also need a round engine 😂😎😎 (SaitoFG90, Moki180 🤔)

[@vicyboy12]

@@RCPLANEVIDEOS but I would this sound on p47 hahaha. I want to try inline engine this time

[@russcole5685]

@@vicyboy12 if you were to make a belt drive gear reduction to lift centre line of engine up, I can't see it being a problem

[@didierneeferc]

I bet its still way over the 90 db's would be cool to see someone make a muffler / dampener that can make those engines go under 90 db's

[@RCPLANEVIDEOS]

Hello, we make the noise measure always with 25m distance. We measure 3 positions which give an average value. The engine had without muffler 79-80dB on 25m (kzbin.info/www/bejne/mni0aGSYgbikqtU) Now with the muffler he has 76dB on 25m ;-)

[@didierneeferc]

COOL but i think they measure it here (at my club) from way closer if i am correct

[@brycekat]

The loud noise high frequency you heard is the propeller tips approaching the speed of sound. A loud unmuffled engine sounds like nascar, larger volume deeper pitch

[@didierneeferc]

@@brycekat i know what i said lol not talking about the high pitch noise of the props. talking pure engine noise. we measure at 7m distance ...
