Dave's radial engine

[usaeagle1776]

freaking awesome!

[Samjapa]

amazing sound!

[biglift1]

one word >> DREWLLL

[n7275]

What's the AKI of white-fuel?

[LakeErieFising]

Flip it around and put your truck in neutral.

[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!

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

[4E047RHH]

@mrcatdoc Real nice engine you got there, Love the old radials, Any idea how many HP it produces?

[vjd2606]

try 7450 t7 alum some goes to t9

[f2cflier]

This is so wrong. Any serious modeller would hand start this beauty rather than wiss out and use a starter. Shame on you.

[PDowling76]

@f2cflier I respect the guy who respects his fingers and hands. No shame in using a starter.

[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.

[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

[Kanoee64]

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

[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

[JustWonderingHowToDo]

I believe the crankcase calls for 6061-T6 aluminum. Would it be okay if I used 6093-T6 for it? Don't know what the difference is between the to.

[pskittle488]

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

[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

[gizmoguyar]

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

[arcanacelestia]

Nice engine BUT you are making a LOT on noise in a residential area ???

[tehklutzking]

Do you make this in a ceiling fan configuration? this would be way better than that dyson multiplier! :P

[bobgriffith3rd]

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.

[SuperNick134]

i thing that your engine its a bit lean

[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

[jdoubleur]

Superb piece of work and sounds wonderful too - I would just love love to start one of those up whenever my neighbours are playing their silly music too loud - it should drown them out nicely !!! I would guess that the cam rings and crankshaft were pretty hard to make, not to mention all the fin cutting - you must have great skill and patience. Well done.

[Tecnogas69]

this radial engine sounds REALLY good !

[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.

[fuji2failo]

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

[mrcatdoc]

thanks

[avsiii]

That's a one amazing, awesome engine...!!!

"I love it, I really, really, love it...."

How much is the plan(s) go for?

[magepwnzer]

very nice work!

[openedeyedbeast123]

how much do you want for it

[mrcatdoc]

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

[vtwinbreed]

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

[robinhooodvsyou]

AMAZING VIDEO !!!!!

[mrcatdoc]

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

its for sale

[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

[screamero23]

Are you building or puting this on a large scale r/c aircraft?

[screamero23]

I just love that engine!!! What kind of oil do you use? Also what diameter/pitch prop did you use?

[mrcatdoc]

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