HelicopterEngines Plugs Mufflers Fuel › O.S 50 Hyper VS TT Redline 53

I have owned many engines including a O.S 50 SXH and a O.S 50 Hyper aswell as a 60 and a couple of 90's heli engines .

Having had enough of replacing bearings and putting up with the imbalance of the O.S I thought I would try a Redline 53 with the new carb.

I am running this on Rapicon 20% and fly hard at 18,000 rpm through a zimmermann muffler.

Its had a couple of gallons now and I have to say I am very impressed so far. The engine is supplied with glow plug and two shims to adjust the compression if need be. I am running without the shims with good results.

The big difference between the O.S and the redline is how much smoother the redline is. Even when running at peak revs this thing seems much happier which I hope will transfer into longer lasting bearings. The carburation is also much better than the O.S with good idle and no transitional rich spot just above tick over.

Now to the power side. This engine does seem to have more torque and is quicker to recover if you do drag it down out of the power band.

I know that people had issues with the earlier redline carb but it looks to me that TT have been big enough to resolve those issue and now have a very nice engine.

If you are in the market for a 50 engine then I would reccommend this engine for ease of use and performance.

I have the Redline 53 no head shims old style carb and it runs top notch. I did pull the carb apart before this flying season and the carb shows no signs of ware. I run Cool Power 30% and a head temp. is running around 200 deg's. I instaled my OS 50 to compare it to the Redline 53. I think the the Redline 53 has more torque, power and runs smoother at a idle. I like it over the OS 50. The Redline 53 is now back in my heli to stay.

I have two Hyper 50's, one YS 50 and a new Redline 53. The Redline is by far the best of the three in everything that an engine should do well: start easily, idle smoothly, transition seamlessly, have minimal vibration and make good power. There could be a reason OS and YS are coming out with new 50 class engines.

So many good votes for the Redline from people who have owned Y.S and O.S

How are those bearings holding up in the Redline?

I own and fly both motors. Both seem to have equal power but I like the OS better for the meer simplicity of the tuning. My TT53s have very good power too.

I've switched to TT.53's for their simplicity of tuning, and good smooth power. Just have one OS Hyper left....what to buy it?

fpenfold, did you change your fuel brand from what you used last year? My TT53 runs great on fuels with 18% thin lubricants like Cool Power 30. The factory carb settings are spot on. However, It has to be richened up about 3/4 turn on the main (3.75 out) and 1 turn on the low speed needle when I run a fuel with 23% Klotz oil like Youngblood Wildcat. Apparently, the added viscosity of the fuel with higher percentage and thicker oil affects the TT53 engine more than with an OS Hyper. At least that's what I found.

F penfold,

Which carb do you have? if you have the early one then that might be your trouble. I think Amerang are doing a straight swap for the new carb.

The new carb is denoted by the base of the main needle housing having 2 nuts instead of 1.

What exploded? The redline comes with a 3 year warranty. Can't be fairer then that?

Sounds familiar! My baffel went last week on my Outrage, they also send me a new pipe. My O.S overheated to badly that it has a dent in the piston, all that after 350 flights its sad. There is no way I will mount that new Outrage pipe.But I am also thinking of getting a Redline I mostly hear good thigs about it.

I heard through the grapevine that they where so contact them and see if they will swap your old carb for a new one.

I have had a muscle pipe header go which caused a lean out on my HZ. Luckly I got away with rehoning the liner.Suppose you cannot expect them to replace a engine because a muffler failed causing a lean run.

I prefer the YS over both the OS and TT,better fuel system and just as much power when you set it up right.
