[@timchapman5567]

Superb engineering and craftsmanship.

[@ChrisB257]

As an engineer - I just love that engine - can but imagine the time put in. Thing of beauty.

[@garysmith2450]

I’d love that for my paramotor😊

[@yiy3429]

Sounds like there's honey to harvest.

[@er1073]

Mr Cat Doc...I admire your skill and craftsmanship...!!! Taking pride in one's self and skills. You are an arist in my eyes you hjave done a great job..!!!

[@kaoskode]

Totaly cool I have been thinking about building an engine from scratch My old man use to buildguns so I have a clausing lathe and a bridgeport mill at my home shop. You do excellent work man kudos to you. 80 lbs-ft of torque is awesome for 7.95 ci. Im on the Texas coast and want a radial engine for an airboat.

[@coffcraft]

I know it's an old post but I have to agree. About 8 years ago, a friend of mine had problems with the lift engine on his hovercraft while cruising the river. He stopped on a gravel bar to work on it and while running and messing with the plug wire, it shocked him and he jerked his hand into the spinning 6 blade fan on the intake side. They saved his fingers but it looked like he stuck his hand in a wood chipper.

[@pskittle488]

Wow, what a machine. That thing makes a hell of a fan. Awesome vid.

[@mrcatdoc]

thank you for the comments , sounds like you have some nice tooling .I love machining ,soon I'm going to get a monarch 10ee lathe .im thinking of making a V-8 using the heads and cylinders from this engine

[@stevecraignet]

Yeah, I have to agree... my neighbors would call the police first, followed immediately by the zoning people. But gawd, how I love that sweet sound! GREAT JOB!

[@anmichall]

Very nice, love the idle Good craftsmanship thanks al

[@mistermellow001]

Truly a work of rare skill and craftsmanship! One thing that made me cringe: Obviously, you're fully aware of and avoid the propeller. But say there was a fluke mechanical failure - say a valve spring breaks, a valve drops, and parts go flying. Your involuntary autonomic response would be to pull away. Your conscious awareness of that propeller, no matter how acute, would evaporate for a split second, long enough to lose a hand. You really need to shroud it. Ugly, I know, but shit happens...

[@Tecnogas69]

this radial engine sounds REALLY good !

[@ErnestoTani]

amazing sound!

[@robinhooodvsyou]

AMAZING VIDEO !!!!!

[@strawboss59]

Superb,a work of art! Did you carve the propeller as well? I think the engine could power a ultralite hangglider type aircraft, I flew RC planes years ago but wouldn't want to prang a model plane with one of these in it's nose....

[@mrcatdoc]

I would say there is some god given talent thank you for the comment i do enjoy maching it keeps the brain in shape

[@mrcatdoc]

I've used 7075 for the cylinder heads,master rod and slave rods its plenty hard holds threads real well and machines nice,and easy to find scrap at metal yards.most every thing else is 2024.thank you for the comment

[@2CabrasLocas]

Potential engine for the coolest lawn mower EVERRRRR!!!!

[@mrcatdoc]

thank you for the comments,at the time this video was made this was the first run-in, at the time you mentioned I was tweeking the main jet,the engine was running on colmuns lantern fuel.I found out ,the lower the octane,the easyer it is to burn.

[@akalsehatid3977]

Ilike this sound

[@vtwinbreed]

This would make an expensive, but awesome, ceiling fan.

[@mrcatdoc]

thank you it took me about a 1000 hrs of labor to machine and build this engine. its for sale

[@mrcatdoc]

thank you for the kind words ,do try to make the best possible engines

[@mrcatdoc]

thanks

[@pontiacgirl73]

nice.

[@avsiii]

That's a one amazing, awesome engine...!!! "I love it, I really, really, love it...." How much is the plan(s) go for?

[@fuji2failo]

dawm, and my neighbors think that my weed-eater is loud i have to move in in your block,,nice VId

[@Kanoee64]

My dog would want to bite at the prop, probable a bad idea eh?

[@Coyotehello]

So I just saw the video today, very nice I have to ask, what happened to that beauty? I agree with another guy who posted that your neighbourg must hate hearing this thing! did you change the mixture at or around 3:30min? the engine sounded much better. I love that it runs on straight avionic fuel. too big for my application but wow, congratulations! A year later!! LOL

[@biglift4365]

dear unca Dave , did you finish my engine yet ? Mom told me you would have it ready before christmas. i dont mind much if its a little later . let me know when i can and come pick it up :) *grin*

[@mrcatdoc]

the cubic inches is about 7.95.I suppose you could upscale it,it would be a major job though.

[@TonyHerstal]

lol, do you made this model? be yes: you are very very smart man! omg very cool!

[@Stahlflug]

The Neighbours are happy with you? ( a joke ) Thank you for this nice Video and have still a good time.

[@ReggieRailSystems]

Have you ever seriously considered (I mean "seriously considered") the MFG/production of this engine or slightly smaller radial engine for the world wide RC groups? I am sure you know, the only MFG'ers of small RC radial power plants are outside the USA. Certainly, it takes funding plus marketing/sales understanding that the establishment of a notable lower purchase price per unit would give a quality USA made produced a stable controlling niche in this growing RC radial engine market.

[@vjd2606]

try 7450 t7 alum some goes to t9

[@richardholroyd1989]

Would make a huge model aeroplane...maybe power output too great for true scale .....eg "Steerman " where the engine would not be to scale.

[@pyromohanzed]

Is it possible for this to power a small car like a pontiac sunbird or a geo metro?

[@Law19157]

what's a 250 cid? ..is the radial engine going to be the same size as the one in this video?

[@mrcatdoc]

the engine is still breaking in so im running a straight 50wt. mineral oil after broke in a 15w/50wt.oil

[@GaryFlymore]

wow.............. man........... ;-D

[@ryanjames170]

what is the cubic displacement of this engine? and could it be upscaied some?

[@bdrman2004]

I dont know how many people have the same name as you do buddy but a few years ago I found a few personal Items belonging to a man with your name in Torrance California. Could that be you? Love the motor also.

[@gizmoguyar]

What kind of power are you getting from that thing? rpm? torque? displacement?

[@Law19157]

How much hp does it produce?

[@mrcatdoc]

I dont know the horse power but the torque I estimate at about 80 lbs-ft

[@melcopc]

Hello, can I have an engine like that? I really enjoyed! I'm from Brazil and build giant models, Radial'm wanting a long time. Abraço.

[@slayboomer]

Paint prop tips RED...

[@melcopc]

Hello Mr and asks for two engines?

[@openedeyedbeast123]

how much do you want for it

[@mrcatdoc]

I would avoid 6061 if at all posible the harder air craft aluminuns machine alot better,such as 2024,7075(super hard I recomend for cylinder heads )go to scrap yards look for rem

[@yonglee1026]

good, engine! do you have agent in china? hoping we can being your agent in china.

[@mrcatdoc]

this engine is not going on a rc plane an engine of this type should have two ignitions for flite.this engine is for sale most likly a collector will by it

[@SuperNick134]

i thing that your engine its a bit lean

[@Tremolux59]

Is there a supercharger in there?

[@ryanjames170]

no not make that kinda HP ud need one of atlest 250 cid

[@biglift1]

one word >> DREWLLL

[@bbycrash]

he cant talk about it, made in a shop that is supposed to be making somthing else,, it takes millions of dollars in tools to make this,probably ,,a union machinist, likr i used to be only worked 2 hours out of eight then we played cards

[@Law19157]

know this thing is really small, but you suppose one could get 400+ hp & torque out of a radial motor that size?

[@mrcatdoc]

im asking 10,000.00 but ill take less make me a good offer

[@bufferbrown]

I would shut my dog away first

[@ryanjames170]

the engine in the video could never make anything close to 100 HP let alone 400+HP to make 400HP or more u would need an engine of 250cid atlest but relisticly in a slow turning radial you would need someting like 700+ cid
