Hi, i have a raptor 50 with OS50 hyper engine. Is it normal to have excess oil coming out from the ehaust?

Yes. Glow fuel for helicopters is between 18 and 23% oil and very little of that is burned and what doesn't burn has only one place to go and that's out the exhaust. The good news is that it carries a lot of heat out with it.

Yep thats why we call them slimers.
Stick your finger on the back plate of the engine right after you land, if its cold you are running too rich and getting raw fuel and oil, if its warm you are good to go and if its too hot to hold your finger there for several seconds its too lean.
