Either are good.

YS uses no muffler pressure, the needles are pretty much set and forget, but they are more expensive. IMO power is about the same.

parts are cheaper for the YS, the initial cost is alittle more..power I felt was stronger on the YS but not enough to really make a huge difference. the ys is smooth, consitant, powerful, and it has a closed fuel system..you cant beat it.

But haveing said that the hyper is a good motor as well, but IMO, isnt nothing overall compared to the YS.

Either motor will be fine, only the Align muffler has lots of reported baffles issues.

the align makes tons of power for the YS, arguably the most powerful pipe for .50 helis... Dont let the baffle issue scare you, Ive had plenty with no problems, and alot of people I know have them with no problems..

I would say go for the OS 50 or Align they look the same. I have the YS 50ST and its been a big pain in the but if you ask me. Bad bearings after only 6 gallons of fuel not good, there are allot of others that have reported the same with YS engines as well. GO FOR THE OS/ALIGN save your self the hassle.

Ugly can be fixed stupid is forever!

The 521 is better than both of those and makes more power than the align muffler.If you cant get a 521 get the 522.The OS runs good and has good power but the power fades away quicker than the YS.The YS has a far better fuel system and will run consistant for the whole tank of fuel.With the OS you either have to start it out rich at the beginnig of the flight or run a header tank to get a consistant run.

YOU ONLY LIVE ONCE..IF YOU LIVE IT RIGHT THATS ALL YOU NEED
