RE: Help in ID'ing plane
Depends on the region. Over here where I fly we love YS engines. True they are not as easy to set up as others and take special care but once you learn the care and feeding there is not a more powerful and reliable 4 stroke out there. Things I have learned about them, always use 100% synthetic fuel, OS F plug, set the regulator to flush with housing and for the most part leave it there and always let it run a little bit to build pressure in the tank before advancing the throttle.
