Without choke it cannot be started by hand. the carburetor has to be flooded until it makes a smacking noise, then it starts immediately. I own and fly this engine since three years.

Exactly, obviously dry at the beginning, then a typical RCist grinding away with a electric starter, eventually it suck up enough fuel to pop.

it has often been said that the difference between man's and boy's toys is the price

I agree

Bill, that is a work of art, sounds bloody awesome

Super elegant piece of machinery! Wow!

Cool....I love radial engines . Flipping awesome.

Will love to hear it in the air. I was worried it was going to pull the Workmate over!

Sounds really smooth. Well worth the wait!

5 minute video,....one minute of engine running.

It was being stubborn at first but you showed it who is boss! lol! Sounds awesome!

A piece of beauty I wish I had one.

Beautiful, what a lovely engine. 👍

What a sound! Best 115 cc I've ever heard. Or 250 or 500 etc etc...

Absolutely beautiful thing, such a great sound.

Superb videography. Incredible engine. Hats off to you

Wow , listen to that thing , sounds beautiful 🤩

Looks like a perfect engine for the bicycle

Beautiful little radial engine 👍

You may just convince me there is more to life than Watts. That is awesome. Please post when she is flying, that will be one big bird and worth the investment!

Beautiful engine and so quiet...

Thanks for keeping film running. And you asked for smile. Nice.

So bad ass wow 👌 I only wish that 1 day I will have this much skills!!

Beautifully engineered and crafted!

Cool engine. It'd be a pain in the butt to have four of those in a plane to start.

A thing of beauty!

Incredible job!

All I saw at the beginning was that thing starting and pulling itself into this man at full speed. Very cool engine, wobbly stand, though.

That's a lovely little engine

Amazing. Beautiful piece of work.

same every time they were near the spinning prop

I like it, I like it a lot. Cracking piece of engineering.

Vultee Vengeance Nashville Tennessee production. This radial reminds me of that aircraft.

that's a powerful engine, look how it bent the prop.

Beautiful! ...If it's half as powerful as it looks, that frame to which it is bolted should be secured via cables to spikes anchored to the ground some distance away aft.

Wow.. impressive 👌

Wow!What a sound!

Beautiful. 👍🏻

That is a lovely work of art.

brilliant engineering

Well done Bill!

Well done! Glad you didn’t go the electric route for the engine as well.

Great sound. Would love to see two of them in a RC Grumman S2 Tracker.

TRUE BEAUTY OF ENGINEERING!!!!

Perfect Work!!!! .....

Actually it is a lack of contact that you have to have to start an aircraft engine since contact of the magneto is never broken but shorted out to keep it from firing.

I'm a woosse, I hated seeing your bare hand flipping the prop, but, I love the result:)

When I was 10 I built and flew model planes, we started them same way.

A beautiful thing...

magnifico!

Hello my new friend this is an awesome video I really like this video.

Awesome 👍 Someone should make an airplane to go along with it.

Every time you have an opportunity to be friends such a person then you should take advantage of that and treat them with lots of kindness and respect because these are the type of people who teach you lots of things about life.

So smooth:)

Bill's famous quote I don't know if it will start by hand in between eating through a straw. Animatronics at this present moment are developing robotic fingers for Bill. Friends and loved ones attended the funeral for Bill's fingers 3 months ago it was a beautiful service

Nicely done

You need to prime the motor, like the full scale version. Then it will start easy.

A couple of guy ropes wouldn’t go amiss😀😀😀 Amazing workmanship.

I don’t know which is more pleasing to the ear, Bills accent (Welsh?) or the engine😀

Magnificent engine👍👍

WOW! Spelled W.O.W. Very COoL.

Awesome engine👌🏻

Very cool! I used to beat hell out of my fingers trying to state my little .049. This thing would tear your arm off. Haha.

I imagine if he'd just wanted something to just make a prop go round he would have done what you do. But nobody would watch a video of what you do. This is a guy with great skills and dedication at the point of bringing something amazing to fruition, and that's what you got. You must have a hard time keeping up with the dinner party invitations.

i would wear leather gloves for starting as this motor will take all your fingers off and still be running. what a complicated piece of kit....well done for getting it started...scary stuff when in a plane i would only have electric start for this one....at least all you have to do is push a button on the tx and it will start.

SUPER COOL!

What a sound from such a small engine, that prop could have your hand off!

Alright I need four of these for my B17 model

Very nice engine

Fantastic!Would be perfect in a motorcycle.

Bravo.perfect

Little boys never grow up!!! Only thing changes is their toys and how they play!!!!!

That's awesome it would be perfect in a motorcycle.

Is it a bought off the shelf engine or home built? The prop shapes are due to the “Rolling” shutter of the camera sensor, where the pixel rows are read out in sequence, unlike a more expensive design that uses a “Global” shutter where all pixels are read out simultaneously. Thanks for sharing very nice engine. Greetings from Tasmania Australia.🇦🇺🦘👍

Off the shelf from UMS they so a range of 7 and 9 Cyl engines. Nice to see someone who understands global shutter - hard to do with CMOS sensors but can be done. Simple to do with CCD sensors as they have masked off storage areas - a bit like winding on film - CCDs used to be more sensitive than MOS years ago but MOS sensors had billions of deveopment money thrown at them for mobile phones. I spent my life in imaging :). Was UK CCTV prodoct manager for Bosch before I retired. Just saw 4K introduced into CCTV :).

Sweet i want one

I fell asleep, but woke up when it finally fired.

4:20, Finally!!!! Sounds good.

It would be great if it had an on board electric starter motor.

Шар земной мы вращаем винтами, от себя, от себя

Every radial engine iv ever seen large or small has always seem to be hard to start ,,why is that so ??

One would surely think that using an electric starter would be worth it here. One backfire can cause a lot of pain.

Be on the lookout for flying fingers.
