Which is best muffler for OS-50 Hyper?

[999R]

Which is best? Any recommendation?

[mplourde]

Muscle Pipe 2 or Hatori... But I prefer MP2... :smokin:

[DebianDog]

The Hatori JK-50 if you have the money.

Which is best? Any recommendation?

To honestly answer that question, someone would have to do a complicated comparative test, and illustrate power output across the throttle range, sound level, fuel consumption, etc. Even then, there would still be other factors to consider such as appearance, weight, whether the canopy has to be cut or not, crash durability, and how each reacts to different fuels, plugs, etc.

Which is best would ultimately be decided by individual preferences. For instance, I really don't care how great a muffler is powerwise, if it's damaging my hearing or has a o-rings and a clamp, I'm not interested. Others don't care about noise or BS mounting, so long as they get maximum power.

It's hard to know who to believe and what leads them to prefer one muffler over another. A couple of weeks back, I talked with a guy who had 2 Hyper-powered Raptors, one with a TT Muffler and the other with an MP2 and he told me that he honestly couldn't tell which one was making more power. He even swapped the two around with the same result. To him, the sound was the biggest difference between the two. That goes against what many others have said, yet there he was with both, so how could anybody argue? Well, maybe he likes his headspeed at 1900, whereas there would be a noticeable difference in power between the two if he had tried a headspeed of 2000. Or maybe he is better at setting the needle when using one muffler vs. the other. Or maybe he is just plain nuts. Or maybe he's right on the money. All things considered, his opinion about the two means nothing without finding out a lot more information about how he came to his conclusion.

I think, like many of us, that you're going to have to try a few mufflers before you can decide which one you'll prefer.

Good answer Mike. :noteworthy You are 100% right. One mans favorite is anothers least favorite. The many choices make it hard to figure out without trying them or at least hearing and seeing them fly. I run 2K on the R50 head and prefer the MP2Q which is still kinda loud or the Funtech which is a lot quieter but stil produces good power. I have had the JK Hatori, but I like a more simple less fussy design that does not need a TMoore mount to be really nice.

In defense of the MP2 it really likes to rev and to get the hyper up into the zone at 17000 where the mp2 really performs he'd have to be running 2000 rpm. At 1900 the engine was turning at 16150, not sure how much of a difference that would make.

I could tell a difference with the MP2 over the stock TT muffler though not a large one.

Well Andy, I may just be sticking to the TT muffler for a while. If a pipe made a really drastic difference, I might shell out the money, but my hyper runs really well and has plenty of power. Not saying other mufflers don't make a difference but it seems to be a mental thing.

I can't keep up with the Jones' and it makes the hobby not as fun when I try.

I have been thinking of upgrading from my TT Muffler on my Hyper 50,,but I run 15% nitro on it with nice results at least for me.
I think I'll go for a GOV and then later a Hatori and 30% when I can really use it.
These things can be money pits ,,so I will say no for awhile and buy lots of fuel and new bearings!!!!!:smokin:

[Motions]

Actually, if you just jump to 30% you should notice a nice difference in power. You may not even want another pipe.

[turboomni]

I get around 10 to 12 minutes run time on 15% now with the TT muffler.
I don't want to go to 30% now because the run times will be alot lower from what I hear,,more power for sure but lss run time.
I still run a Raptor 30 and get 15 - 18 minute runs.
I wished TT made a bigger fuel tank for the 30-50 class heli's. It's not a weight problem for a 50.

[Mr-C]

It's not a weight problem for a 50.
My guess is it would be a mixture consistency problem.

[SteveL]

It is all input and output math. Input = Fuel output = Power The more power you get the more fuel you will burn. That goes for a high performance muffler or higher nitro.

I find about 10 mins is as long of a flight as I need.

Here are my thoughts.
I have two 50's set up similar.
They both had the stock TT mufflers.
After a crash that damaged the muffler I replaced it with the Hatori JK-50.
The first thing that I noticed is that the needle had to be opened a few clicks more than a half turn, most likely due to less back-pressure.
The JK is huge compared to the TT yet about the same weight (I did not weigh them so it is just by feel).
I have noticed an extra 45 seconds run time from a tank of fuel. with the JK.
I have noticed less mess on the heli after a flight with the JK.
There is a lot more power available with the JK. Both of my helies would bog the head bad while I am learning funnels. now the heli with the JK does not bog the head but the other one still does. As I am learning they are both bogging less than before.
The same is noticed for Tic-Toc's.

Looks and ease of install take a distant back seat to performance for me.

I have never flown a MP so can make no comparison other than observations of others ships.
The MP seems louder than the JK.
I have seen 2 crashes now where the MP survived with just a slight dent and the engine block was riped in half. I have flattened other mufflers with no engine damage. This is not to say that any crash with a MP will destroy the engine or to say that a crash with a different pipe will not hurt the engine, I'm just mentioning that the only engines I have personaly seen damaged in a crash landed on a MPII.
