Got my webra on song today and it was rocking. Climbouts were on par with my hyper 50 with hatori 544. This is currently running on 5% nitro with 20% kl198 oil.

will hope to get video next week. Going to push the nitro up to 10%.

cheers

I started this thread when I saw a magazine announcement about the WEBRA P5 .55. Ok, now that OS Max has dumped the original OS.Max .50SX-H ring but still offers the .46,(what were they thinking)
My point, the 50-size helis take off and the fricking engines disappear. Horizon drops the WEBRA .50, MRC/Altech which imports the Hirobo line of helis, drops the ENYA .50 HELI, OS Max drops their standard .50, and YS doesn't even offer one. So your choice is the Thunder Tiger .50 or the OS Max.50 HYPER. What use would the ordinary novice or intermediate have for a screaming HYPER?
Now the question, who is selling the WEBRA P5 .55 in the USA.

Why do you want the Webra 55?
A novice turning up to any given club in USA
is not likely to find people with Webra experience
to assist the novice. (Europe would be different)
AMoss007 gave up on the Webra - it did not perform

The TT50 is a nice engine, works fine and is cheap.
The OS50 Hyper is a great engine,
many people learn to fly on it,
it only screams in idle up (as all 50's do)
and you get used to it.
These two engines are very common,
people in every club will be able to assist the novice.

Why do I want a WEBRA .55? I like the pro-mix carb, easy to set and forget. I have three Thunder Tigers, yes, nice engines that run well and are powerful. My point is, OS had two nice engines, the .50SX for everyday flyer and the HYPER for those that like to fly with their hair on fire. Why WEBRA, because it has been a heli standard for over 20 years, .32 red head, .35, .50 and so on. But between Hobby Dynamics, Horizon, Advantage Hobby, Great Planes, and so on, all that fricking confusion in central Illinois keeps picking up and dropping engine manufactures and has influenced what is available for so long.
Super Tiger got dragged into COMO engines by INDY RC, then shuffled off good manufacturing to China to make Tower clones and messed up a good engine line. Now we have all the other crap, EVOLUTION .52 and IMZ, not to mention the English junk, IRVINE, MDS and Korea junk GMS and so on. I have found that the ENYA SS .50 is still available and has an option for 3-needle carb but just isn't pushed by anyone. Even at IRCHA, Jeff Green used OS.37 engines for the build off instead of his companies ENYA .35. I loved the build off and I love OS engines, just don't like marketing pukes pulling the plug on good engines like the OS Max .50SX-H. I want serious choice and as you point out, I have only the HYPER at .60 prices or Thunder Tiger and ENYA. Where is Rossi's 50, or Super Tiger, or YS, Jett. That won't happen anytime soon. As you can see from the earlier post, the South Africans, New Zealanders, Aussies are all flying the new .55 P5 Webra. Guess I will have to order one from overseas.

Irvine are far from junk and MDS (which are true junk) are Russian .

I'll second that. Irvine are excellent and very powerful.

Anyway, the Hyper 50 is not only for Nitro heads. It runs very well on a standard muffler and gives great torque across the rev range on a muffler or pipe. Its an improvement on the SX-H so the SX-H is now redundant. I flew my Hyper on 15% Nitro at moderate head speeds and it never missed a beat. It also performs very well at 20% Nitro and 2100 head speed (R50SE) so it will deliver top end performance if you need it.

For very little power increase the Hyper is 33 percent more expensive and with the original you don't have to grind on your Raptor side-frames.
OS.50 isn't redundant, the OS .46 being in the line is redundant. And in the US market Irvines are junk, a miserable market flop here.
Seem to be alot more Hypers shedding liner material and galling he piston and messing up than the standard .50 ever did.

Isn't the Hyper and the standard 50SX both share the same liner. With a bigger cooling head, should last longer if they run at the same RPM.

if OS made a heli engine as good as the irvine 53 then we would would be in for a really nice engine. irvines are THE best engines i've ever had in a 2 stroke application. if they only got the finger out for a 50 heli application, the irvine 53 heli never appeared though altough rumoured.

MDS made in uk? did you get that from the same source who said irvines are junk?

cheers

We all seem to agree on the quality of MDS. At our club they have earned the name:

Well after all my venting and spewing about .50 size engines disappearing, I have found the WEBRA .55 available from ADVANTAGEHOBBY.COM in the US for $188 with free shipping, and yes
MRC has the ENYA SS50TN avaiable for $129. And ADVANTAGE has the lowly OS Max .46 for $109 with free shipping, and there is always the Thunder Tiger. So take that $209 HYPER($199 at ADVANTAGEHOBBY)!!!! bitch, bitch, bitch, if I wasn't bitchin' I wouldn't be breathin.
shut-up and buy an engine. BTW it wont' be an IRVINE or MDS.

Dial,

Have you run OS46FX-H?

$109?

That looks like a pretty good deal to me. I flew that motor for a year and a half all on the same rear bearing!

The 50 hyper makes more power no question, however you're saying you don't need all that power. Why not give it a go?

andy-

Proofread carefully to see if you any words out.

Drop a tooth on the pinion, it'll wake up.

The motor has a shorter stroke comapared to the OS50.

.807" vs .847"

The Webra 55 has a mechanical disadvantage right off the bat. To make up the torque you have to push down harder on the piston.

Or,

spin the motor at a higher RPM.

I may have a slightly used Webra 55 for sale if anyone is interested. Send me a PM please. I no longer fly the 50 size helis so I have no need for it anymore.

$115 shipped ConUS. Paypal OK.

Did not see any post of Amoss007 giving-up on Webra. His early post looks promising for the Webra engine. Whatever happen to his engine that make him give it up?

Jafa posted that.

His location is Sydney same as amoss007, I suspect they fly together.

Yeah guys, Andrew did give up on the Webra.
We are both going through that hungry stage
where we can basically fly and want to learn lots of stuff.
Messing around with this engine was a distraction to flying.

We had a day at the field where the Webra played up on us,
we were hovering in hold mode!
And it would not come on song that day.
I fully accept that we need to strip it down,
there must be a fault with the carb.

Andrew just threw his OS50 back into the Sceadu.

In hindsight Andrew reckons the Webra did not come close
to the OS50 performance,
but we accept that we never got it sorted.

It ran in easy and showed promise early on...
I will have another look at the Webra one day...
From Andrew's point of view,
the Webra is destined for a plank
but it is good for long flight times and low running costs.

A different Andrew here!

My 55P5 is still going like a train. Really happy with it. I have 2 (used) hypers sitting on the shelf and am running the 55P5 and YS50 in my two R50's. The Webra has had close to 300 flights since May. Have just changed the rear bearing for the first time (similar life span to the OS).

As far as I am concerned mt next 50 will be another Webra.

They are arguably not as straight forward to set up as the OS, but the engine gets better and better.

I had blown maybe 4 plugs in the 300 flights, so when I changed bearings I added a 4 thou head shim. No change in power, and perhaps glow plug life will improve. I think the engine sounds nicer with the shim. 15% nitro - and matches or betters the power of the OS on 30%.

Pitty I cant make the 91Hi work ......
