Default Rate the YS 56 Engine!

Hi guys, I have been flying 2 OS 55's for the last year or so and I am getting tired of the rear bearing maintenance required. I use top quality bearings and fly at least 2 days a week and still can't seem to get more than 100 flights out of a set of bearings comfortably. I am seriously considering switching over to the YS engines and would like your input on the pros and cons for this change.

Thanks!

Trying to not start an engine war, both engines are very good.
I really like the consistency of the YS due to the pressurization, something that bothered me with the OS55. The YS also makes a bit more power.

Grab a YS, sell one OS and you can do your own back to back comparison!

good suggestion, I actually have 2 buddies that have the 56, but they haven't had them long enough to really test them over the long haul yet. I am very impressed with them so far, enough so that I am really considering leaving OS, a manufacturer that I have stuck with for years. I love there engines, but they need to put a larger rear bearing in and fix their design flaw.

I'm pro YS, but have an OS55 as well, and have no excessive bearing wear to speak of. What fuel are you using?

use Rotor rage, Rapicon, or Wildcat and your bearing issues will decrease

I've had 1.5-2 seasons on my OS motors and no bearing issues and I run them at HIGH rpms due to the porting.

It's not an oil related issue or I wouldn't be getting 300+ flights on my redlines at 2250HS

John, do you tune on the rich side or right in the sweet spot?

I had my doubts about the YS56 after watching people struggle with the tuning including a guy who has only ever run YS and couldn't get the power he was expecting. Recently though, as the YS increases in popularity in Australia and I see more going hard I have come around to the dark side and would recomend one any day!

I am still holding out for the RL56 though, only because I can tune them reasonably well and I am crap at tuning!

We have a mix of OS55's and YS56's in our club. The YS consistently produces slightly more power than the 55.

I have the ys56sr in my sdx. Runs very nice, love the consistency due to the pressurization. In my opinion the running in process is critical on these motors, they take longer to run in and settle down. Mine really starting to settle down after 30 liters of fuel. Tuning, sensitive as hell but one you master it . Really pay attention to you external fuel tubing and ensure no pressure leaks what so ever.

Bringing up the old topic, I hope you don't mind
What do you guys think, will YS56SR work well with CoolPower 15% fuel?
I'm finishing my .50 build, and only fuel that I can get in a short time is CP 15%
Thanks for your input

Might have to remove or add some shims to change the timing.

OK thanks Dominic, I see that the manual says it should work with 15-30% nitro, but with 18-23% low viscosity oil. I think I'll try with stock shims, but I'd like to add some oil to Cool Power, because it has only 17% of oil. Can you suggest me which oil to use?

I guess I'll add about ounce and a half of castor oil to a gallon of CP 15%, we'll see

I'm just curious, how are you installing the bearings? are you installing it cold or heating up the block expand the hole? and also are you pushing on the outer bearing race when you put them in? just food for thought. quality bearings will get pre-mature wear when not installed properly.
