I'm sure there are varying opinions, but back when I was flying regular 10 years ago Webra was one of the powerhouse engines to buy, I found out they are no longer in business, so who's are the engines to buy that may be comparable or better than webra now days?

Rossi might be 'hot' too, or maybe people assume that just becasue they're Italian!

I always thought it was the Rossi engines that were the super engine to have. Then Jett came along and took over the top end of the engine market.
You can still get Rossi engines too.

At the very top of the list of 4-strokes, the YS70 is leaps ahead of everyone else in that size category.
I'd second that Jett has the top spot in two-stroke land.

Sport_Pilot

If too pricey Fox is a good second to Jett. Others still avialable in the same class as Jett is Rossi, and Novi Rossi. Not sure but there may be a few high powered MVVS engines as well.

If a .60 is the right size for you there is the HP line available from Mecoa. They are almost the same as Webra but with a singlequality control issue, namely the rings of some seem to have poor compression, though I understand a new ring from Mr. Bowman can fix that.

Sport_Pilot

I think the Nelson's were the best, but they recently stopped producing those as well.

Sport_Pilot

We mentioned two stroke engines for a reason. YS does not come close to a Jett for top power and speed. But for pulling a slower plane straight up it would be a very good choice.

Sport i think you havent flow a warbird with any YS engine to see how good they are. They will out perform any = size two stroke.

Of the two strokes Jett makes a bunch of different engines but only a few of his sport engines are on top. i will run down my list of engines and brands per size.

.15 size is the magnum

25-35 size:
1. Jett 35
2. OS 37H converted to plane use
3. 35 AX

40-60 small case size
1. Jett 56LX nothing yet has beat it and never will with a production engine!!!!!
2. Evo 60NX
3. webra 55
4. Novarossi 57
5. OS 55AX
6. Magnum 52

61-95 size engine small case

1. OS 95 AX
2. jett 90
3. magnum 91
4. ST 90
5. tower/gms 76
6. OS 65 AX
7. Fox eagle 60

105-135 engines

1. 120AX hasnt been beat yet!!
2. Jett 120
3. moki 135
4. webra 120
5. TT 120
6. OS 108
7. MDS forgot size lol
8. ASP 120 has same power as a magnum 91

Four strokes

1. YS 170
2. Saito 220
3. Saito 180
4. YS 115
5. Saito 125
6. Saito 91S on 35% is same as YS 70 on 20% If both on 15% then saito has more power
6. YS 70 has more power on high nitro than the Saito 91S

aspeed

Profi, Fora, Novarossi, Jett, Nelson, maybe Picco, Rossi OPS would be an ok choice too to a lesser extent, up to a .40 size. IMHO

I did put two-strokes and 4-strokes in a different class if you actually read my post.

Jett is a great engine..just can't get Dub to them for us Free Flighters who play in the 21-24K AMA gas classes.

Where can you buy Profi in the states?
Where can you buy Fora in the states?
nova rossi in some apps are good.
A few jett engines as i mentioned the others are not that strong hence not many sold or discontinued.
nelson make any sport engines?
Picco, Rossi and OPS = heavy lol

not knocking good engines but not readly available or am i wrong?

aspeed

I think Hobby Club carries Fora and Profi. 

Sport_Pilot

Then they may be selling NOS from somewhere, but Icannot find it on the manufactures website.

Not on a sleek plane when top speed is compared. Speed = Power. Climb and low to mid speed aerobatics = torque. He asked about the most powerful not the best performing engine for a warbird.

djlyon

Here is where you get the Nelsons. Mike Langlois now makes them. Mike worked with and made parts for Henry Nelson in the past.

Dave Schadel of pspec is retired and no longer sells the engines

Did you see that Dubby got an award for attending the NATS for 50 years in a row? Great man and I am a supporter of his products.

Are you referring to CL/stunt engines comparisons? The Fox ceramic CL would intrigue me if it were RC.

I learned something wonderful today! Good to see these are back!

The YS 70 is lighter than an OS 46AX but it sure seems to put out more power of all kinds.

that YS 70 is a great engine. it would be nice ith YS made a 20 or 30 four cycle lol. just think House of balsa 1/12 scale warbird with a YS 30 FS turning a 8x10 prop at 16,000. fly these small planes on a 400 foot course at 150mph lol can you say intense.....
