Thanks for your reply.
I know all that

As i said ... I would take hit for 52 engine if I could be shure that chinese ASP 52 is comparable with for eg. OS max 52.
I dont want a rocket.. but I'm afraid that this ASP is not so strong. So wondering if ASP 61 will be more close to OS max 52

Thats all I want to know

.. Still searching this info

If I could buy Os max .. I would take 52 for shure!
Didn't see those ASP engines working before
