| I have had one problem with OS 50's,, I had one grenade. It was probably my fault but as per instructions I sent it in to OS they looked it over and said.. We'll replace that! Sent me a new one, and a mere week transpired between not flying and flying that airframe. I have gobbs of power in all of my Hypers, extra to spare even. Almost everyone I know is running hypers due to the power they produce. Now if we want to talk failures and lack of power. I have personally owned 7 OS 50 motors. I have friends that have owned quite a few. To date, two failures known, my grenade and one friend blew out a conrod. Now I know of three YS 50's all of which idle great, run smooth, but with so so power, they never produced it. They have the power of the stock OS50 pretty much. I am talking Hyper power requirements, that's what the world needs to be happy 
Now you want to talk about 90's well then why didn't you say so.. YS all the way. But nothing in their class can touch the hyper 50's
