Evolution 77cc Radial Engine
Вставка
- Опубліковано 18 бер 2012
- Originally designed in Germany specifically for use in scale R/C models, these engines are particularly suited to models with radial cowls such as the F4U Corsair -- Sea Fury or firewall mounted on vintage aircraft with no cowling such as the Stearman PT17.

What a lovely sound from a sweet engine. Wish they had been around 40 years ago when I was into RC
Great engines and im sure that they will be even better in the future. Thank you for your time and for posting this. I love it.
Glad to hear you liked the engine, they are proving to be very popular and of course the perfect choice for scale models.
The prices are listed here umstech.in/radial-engine.html
very nice video and of course the engine is great - good sound!
so silent and smooth!
I love my evo! Going on 10+ years!
If this don't get your heart pumping, you got no pulse.
Nice engines
Adoro los motores radiales Me encantan De joven trabaje con Continental de los tanques M3a1! Sufrian mucho metidos dentro de la carcaza del tanque ,pero al aire libre de un Stearman eran felices Esto que veo es una joya tan fina como un buen reloj suizo Felictaciones Lastima que yo no lo pueda comprar...
Righteo. Lets see you do better. I think its awesome!
A rotary engine and a radial differ massively, a rotary engine is like an oil pump and rotates at high speed using a primary ignition and then a secondary on the same stroke(lead and trail) Radial engines combust in the conventional sense and are more temperamental. Everything mechanical can and will break. Hope this helps.
Let me turn one into a system for paragliding =D
Great advertising =p
if only i had the money for that
awesome
I wish there were a way to engineer a car with a radial engine in such a way that the gyroscopic forces did something useful. I love engines with an odd number of cylinders.
Rotary engines are much more susceptible to gyroscopic forces than radials: In a rotary, the crankshaft is fixed to the chassis of the plane and the rest of the engine rotates around it, with the propeller fixed to the engine block. This turns the entire engine into a big flywheel, imposing limit on size of the engine, beyond which the plane becomes dangerously unstable and impossible to control.
For radial or inline engines, only the propeller and the crankshaft are spinning, so gyroscopic forces are less of an issue. The bigger problem is the torque reaction between the engine and the plane, which exerts a rolling force, even when the plane is stationary. This problem is enhanced by the spiral slipstream (created by the propeller) flowing over the tail. This creates an additional rolling force on the plane, in the same direction as the torque reaction from the engine.
This is however only a real problem for single engine aircraft. For twin-engine aircraft (such as the P-38 Lightning or the DeHavilland Mosquito), the problem is easily solved by arranging the engines to rotate in opposite directions to each other. That way, both the torque and gyroscopic effects are cancelled out. A similar approach could be taken with a car: Use two small engines spinning in opposite directions instead of one large engine. The crankshafts could then be geared together into a common output shaft, similar to opposed piston engines, such as the Napier Deltic or the Junkers Jumo 205.
Alternatively, one engine could drive the rear wheels of the car, with the other engine driving the front wheels. This would add reliability: If one engine failed, the car could still be driven on the other engine. There would also be an efficiency bonus - the car could be driven on just one engine most of the time, only using both engines when maximum power is required.
EDIT: Putting a rotary engine into a car is possible, though usually on fairly unique customised retrofits. One rather insane-looking example can be found on the "Jay Leno's Garage" channel:

Thanks ! Ive seen where the rotory engine was put in motorcycles- Ive waited several long years to see someone incororate the rotory gas engine into a motorcycle frame..cant get much better than that (other than adding flame thrower special effects to the motorcycle dual exhaust) Why do people hate on the flame thrower kits? I'd rather use the oringinal method of rigging sparkplug into the ehauast pipes (bit more work detail involved than that) but if going to do the classicl dragster look....
Beautiful engine -- now that is precision engineering. :)
Will this fit in my honda?
Super :-)
Does the glow igniter set-up come with the engine? If not, where do you get it?
I believe it uses a traditional ignition system. I'm not sure if that particular engine comes witth it, but some do.
I would love to see it in a Red Baron.
How much will one of those Evolution 77cc Radial Engine cost in USDollas?
Can these fit in a Nick ziroli b25 101 inch ? Looking high and low for radial . 3 cylinder minimum to fit my b25
You're aware of the Saito 3-cyls? Glow and gas, also a 5-cyl glow.
How do they prevent wear in the rocker arms with no oil?
A small drop of oil on each rocker before flying .
Hmmmm..I feel a powered footlaunch HangGlider project coming? HaHaHa ;-)
Modelers have wanted them for years, this one is even 7 cylinders, maybe I can mortgage the house I need one.!!!
Ok...how does the valve train get lubricated?
Is it true cars having a rotorary engine cant be blown up ?-how is that possible as like what prevents the rotorary engines not blowing up when going past the redline RPMs?, lot of products say theyre unbreakable...and I still manage to find breaking point-no matter how well made the design is, all machines has a breaking point
well ofc they can blow up but rotary's can happily rev past that line bc the manufacturer put it too low
Rotary engines do not like being revved over the redline.It causes mega tip seal wear on the rotor leading to premature engine failure.The Mazda RX7 is a case in point.Suzuki thought they had cracked the problem with their RE5 motorcycle by introducing a 3 piece seal,but the problem remained.Over rev a rotary and eventually it will go Bang.
Over rev anything enough and it will go Bang.
NOTICE the MASTER AIRSCREW Propeller. This is the one to use on most ALL engines. Far better than ANY composite props. Wood = Stiffer than Fiber-anything + traditional prop edge = least amount of tip drag = best efficiancy period.
Hiya Jamie, yes indeed we think they are very good propellers as well, they have proven to be great performing propellers on a wide range on engines.
+Jamie Lee Call me when they make a four blade prop for P-47, P-51, B-29. Until then I'll stick with the proper prop for the aircraft they're fitted to.
+TestECull I don't understand why some models do have the right 3 or 4 blade prop and others do not. For example I've yet to see a really large scale Spitfire with a three blade prop. Conversely, I've seen the likes of FW190's with both 2 blade and the correct 3 blades. I am not a model maker but I love warbirds and the detail these people go to is fantastic. So why spoil the effect with the wrong propeller?
Adrian Larkins
Some people favor efficiency more than they do it looking and sounding right. These are the same people that take a giant scale P-47 or FW-190 or Corsair and put a brushless setup in the nose. Yes, yes, yes, it's more efficient and faster, but it's also more boring =.=
+TestECull Thanks for the reply. That's really odd from a logical point of view. If one goes to great lengths to make the aircraft look as authentic as humanly possible, I find it incomprehensible that the whole thing should ruined by going the practical efficient route. To me, it's almost a crime. Those scale models with three blade props turning on a Moki 400 are utterly fabulous. I wish I had the time, knowledge and money.
PS I think your nom de plume is a balls up.
Yes mostly RC Scale planes.
Dear Santa!
Correct but OS do make some very sweet Wankel engines that spin up to 17.000rpm and the are reasonably cheap to buy. The first gnome rotary was so called because the whole engine spun round with the prop.
Where can you get parts for Evolution engines?
Does this run premix lube?
Bruce Miller yes
A wellmade radial engine can last for ever if well serviced and its material's
are high performance, which have been carefully chosen by good professional metallurgist and miniature engineers.
Anyone see the oil running down the exhaust manifold?
All glow engines do that. There's no sump, total loss lube system. All the oil runs out the exhaust, it's not a fault with the engine. (I'm sure the OP isn't reading 6 yrs later, just in case anyone else is wondering)
how to make engine?
Good luck with spares after a few years.
It says "UMS INDIA". Does that mean ...?
Build your own 9 cylinder radial engine from plans by Ageless Engines
Sure everyone has a CNBC mill and lathe at home.
If I get one save me a lot of money and time on dummy engine !
I don't have to be a cook to know the soup sucks.
Bet they don't come cheap!
Can you selll in it
you should have gotten an aplus for that
Munny ≡> Noise.
Yes people often call Wankel engines rotary engines. True rotary engines died out many years ago so people think it is now ok to use this word to describe the Wankel. I recently found a suzuki RE5 wankel engine in the packaging that it was supplied in as a new replacement. I posted a short vid.
They have them at tower hobbies for $3,499.99 US dollars.
LOL!
Made in China??
Looks like India to me.
daniel shoop . yes sir, it is manufactured from my city, ums. very old company.
nope it's Hongkong
A lot of effort and expense there. One 50cc weedwacker engine would be hugely cheaper and just as effective..
As nice as this engine is, it's very badly engineered, what with the bad angles on the pushrods, and thick cooling fins.
