Myles ~ Does not sound like the real thing! Has really hollow pipe sound. Should have rocker covers also.

Has a beautiful exhaust note. sound like an American v8 at idle. bet the neighbors love you when you get into those higher revs.

That's a nice little motor

Why am I envisioning this on some crazy little motorcycle! I know it’s only 257cc and that would make a great little dirt scooter but my goodness I would make myself a small Hardtail and have the coolest little chopper in town!

Glorious...love the open rockers...🤔🤔😎

This is beautiful!!!

STUNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNING.

I would love to see two of these engines on a Cri Cri Ultralight aircraft. That would be cool!

holy ....damn.....yea.....love the idle rumble

I need two of those, I wood put it on a little plane. and fly fly fly, thanks for showing nice motor see ya next time see ya bye.

Those engines are incredible! How many hours of use can they withstand before needing to be serviced?

even a pushrod :), great

Lovely engine, would love one just to set up and static run it to enjoy the sound. I would not be game to fly it though as I would most likely end up crashing it!

That thing can power one that you get in and fly with out the R/C.

Hello What is the type and name of grease used for the gearbox pinions of the Moki S400cc engine?

What do you get when you cross a Moki 257, a pusher prop and a Smartcar? One heck of a cool skateboard :-)

Nice vid!! Thanks for making it! But one question on the details? it is 250 cc but how much horsepower does it put out? tanks again!!

Hi, engine hava exactly 252cc and Moki say output approx. 14.5 HP but it is about settings, height above sea, petrol and rpm´s. So around 14 HP it can be.

Burt Ratan's quickie went 235 mph on an 18 horse motor. This thing has to be putting out a bit more than 18 hp.

Moki 257 makes 14.5hp peak

It actually sounds like a big inline 6 at idle. Then gets into more of a flat plane V8 like sound at higher RPMs.

You can see the mount bending forward. You need to weld some supports onto the top corners back to the rear of the frame. That mount will eventually break.

Hi Jay, bending isn´t in mount construction but all mount with engine want to go fowrard. I must add next bricks, if I will not put my leg on it and will go to full gas, mount with engine will fall over. Same situation is with ZDZ 180cc 2cylinder at full gas.

Love it. Pure audio porn. Fantastic throttle response, too. Thanks for uploading!

Would be a perfectly detailed design feature.

A number of questions about this engine: Is the prop running at full engine RPM? What is the estimated horsepower? Is torque, or torque application a problem with an engine this size? How heavy an air frame is this designed for? Thanks

@Dzordzikk

Hi, yes, I'm using it on full rpm too, no problem. This is scale prop designed for this engine. Engine may have around 13 HP or so. This engine is usable for scale models up to 40kg.

@@Dzordzikk It's an impressive scale engine. Makes you think about scaled up versions.

What propeller and hub is that? It looks like something off a small manned aircraft, not a model. Beautiful engine by the way, making me envious :) PS also wondering, does the exhaust ring muffle the noise effectively? Considering getting a Saito 5-cylinder myself and wondering if it's worth getting an exhaust like this

Hi Bernard, this is scale prop for my new project in 1/3 scale - Czech agricultural aircraft Z-37 Čmelák (bumblebee). Propeller (from Mario Seidel - Germany) have very scale sound, especially in windy conditions and pulls very hard because big area. You can look to real scale aircraft, engine and propeller here (use headphones): kzread.info/dash/bejne/fY6azcGhdJrdiKQ.html

@bernardw4842

Thanks for the link, that's an interesting project and a plane I wasn't aware of before. It would make a great model, most agricultural aircraft do, especially withy such a great engine. No headphones but my computer is connected to a nice sound system with external DAC and that video sounds great. I love that radial sound. I worked out a design for a constant speed or variable pitch prop hub but don't have the resources to develop it, I thought the market would mostly be for UAV's with advanced scale RC secondary. That would really work well with this type of engine and plane. The prop is very important to the scale sound of an aircraft as it is such a large part of what we hear - with larger models the engine RPM isn't really so different from the original. Of course it's higher, but usually not by a large factor, and with the right prop and especially as the model passes you hear the Doppler effect, THAT sounds impressive! Good luck with your project, and again I envy your engine :) Hope you're enjoying it - you certainly seem to enjoy the sound! Model radials are such beautiful pieces of machinery anyway but the sound makes them magical. I'm glad you'll be flying it and not just admiring it on a shelf! Best of luck with it.

Hi, it highly depends on used prop. This one have very big area and special profile for maximum efectivity around speed 80-100 km per hour and have very big static thrust. Haven´t measured but I think it will be somewhere between 25-30 kg of static thrust at max RPM.

No pump?

4 more inches in diameter might have a good experimental engine😊😊

how much thrust does it generate (if that's even the correct terminology)?

Hi, sorry, it is some time I have run that engine, so dont know, but it will be somewhere around 3600 ca on ground. Look on my other videos, maybe it can be in one of them visible. But my prop is created for my engine and my flying style specifically, it isnt standard prop,so cannot compare it with different Seidel props.

how much

How much this price sir please

Man these engines sure do remind me of a Detroit Diesel a lot!
