I have just got my new DA100; this is my first gas engine other than Zenoah. I have no idea how to brake-in this engine. The owner manual specifies the oil type (no problem with that…) but says nothing on how to do it. Should the rpm be constant? Should I play with the needle? Should it be rich “four stroke like”? And more and more…
Please advice how to do it.

Thanks
Vanom
