Or have you went big bore with your 50 size? My 50 hyper makes plenty of power for my flying and see no need to go for the latest and greatest. Since this engine is on its 4th rear bearing and 2nd ring change I will probably buy another new one before they're all gone!

I've been flying the Hyper forever and still am. I have a few and they all perform awesome.
There is definitely no power shortage with the hyper50. Anybody who says they're not powerful enough just doesn't know how to tune or fly that well.
Sure more power is always better, but the hyper is no slouch when it comes to making good power. Just need to know how to tune a nitro engine and apply good collective management.
It'll pull through anything.

The hyper 50 is a wonderful engine easy to tune and plenty of power. I have two of them. I have a love hate relationship with this engine though. I love this engine but I hate the fact that I cannot keep a rear bearing in one to save my life.

I will even admit I was blown away by the OS 55 and how much more power it has over the hyper 50. The hyper 50 suits my needs much better though. I can do any maneuver I need or want to do with the 50 and fly a minute and a half longer per tank (guesstimate). Kinda like big block vs small block they both have a set of nuts but one gets a little better MPG. Besides if they think im going to give 300 for a 50 size engine they can kiss me where it smells funny.

ENGAGE!!

It all just depends on the altitude you fly at and the type of flying that you do, I have 3 hyper 50's and 1 55, I would gladly trade my 50's for a 55. As far as bearings, go with the Magnum glide bearing and be done with it.

It is beyond my comprehension why so many people will replace bearings 3 Times a season and bitch the whole time about it when there is an easy fix for it.

I have two and love them. Yes mine did go through bearings but I solved that. Send them to Magnum fules and have their center glide bearing installed. it is a sleeve instead of a bearing. I swear the motor was quieter and smoother after I had the first one done. I now have all my motors running them. It costs $75 if I remember correctly. they turn them around in 24 hours and come with a life time warranty. Just can't go wrong with them.

when you guys get tired of changing rear and front bearing Try using the bearings for the RL53, it'll be the last time you do it!

I thought it was only $50 for the Magnum glide bearing.

I still fly the 50. I never got the 55 because I guess I am too cheap.
The price of a 55 and pipe is ridiculous IMOHP.

If I want more power, I fly the 90 size instead. No there is no 105 or 120 in my near future for the reason stated above.

Have 2 of them and really like them. They are easy to tune and have plenty of power for the way I fly. If I got something new I might try the 55.

Good information there.

I have a differnet view than some of you on the OS 50. punkin71, I had an OS 50 in my Vibe (a fairly heavy heli) and it was a dog compared to how it flies with a YS 56. I'm at low altitude, <100 feet. I fly high load maneuvers and the 50 would just keep bogging under the load you get with funnels, hurricanes, piro tic tocs, etc.

The Magnum glide bushing looks like a good solution to short bearing life on the OS50 and 55. The only problem is that a bushing has more power loss (viscocity shear) than a bearing. It would be better in a big bore. The YS 50 and 56 engines seem to have a bit better bearing life than the OS engines. Not sure why the same size and grade bearings last longer in one versus the other, possibly less detonation.

I only have the OS 50 in a T-Rex 600 right now. The T-rex is light enough that it gets by OK on the 50. My SDX has a NR 57, the YS 56 is in a Vibe and another YS 56 is in a ElyQ Vision 50C. With a heavy machine, even at low altitude, a big bore is needed for hard 3D in a 50 class heli IMO. The Vision is a very light weight heli and, with the YS 56, it is more fun than a 90 class heli to me.

I've been running a 50 hyper in my Rappy for years. It was enough but as I was getting better I was noticing the power didn't seem like it was. Fast forward to recently I built a Velocity 50 and put all my gear from the Rappy into it. It was real doggy until some fellow RR members helped me realize the included Outrage Hyper rage 55 pipe was for the big bore engines so I put my mp5 back on the 50 Hyper and it feels much better and even better now that it is on the lighter airframe. Now I am considering getting a big bore, probably an OS 55 since it is pretty cheap compared to the others. Do I need a 55, I don't think so but it would be nice. A part of me feels like I have a new Dodge Charger but with the 3.5 V6 instead of the Hemi.

The OS 50 hyper can do anything a newer OS 55 can do but the difference is---> The OS 55 can do things ALOT easyer because it makes alot more power.The OS 55 will also hold power much better when you keep it loaded..

I'm not sure I buy the loss of power with the Magnum sleeve. I had one with and one w/o and I swear the one with ran smoother, quieter and has just a hint of more power. I have two .50's and one .90 with the sleeve in and I will never run a motor again w/o one. Actually I sent my .90 off in the box never run to have one put in. I got tired of bearings throwing particles and scratching the piston and everything up. Why risk messing up a motor with metal particles from a bad bearing.

I haven't noticed any power loss from the bushing, if there is any its not enough to notice that's for sure.

I don't thinks it's wise to change bearings out multiple times a season either. Knowing how a ring will take a seat to its sleeve as well as it's piston is not something you want to disturb after it has taken it's set. Just because it has a locator pin doesn't not mean it will take the same exact "set" it did during original break-in.
