Thx for the info TambokGT.
I met this guy at KZ who's running his own engine on his reflex. I don't know the spec on it, but west coast hobby will distribute this engine soon according to him. This guy only mentioned it's 39,000rpm and it's made in italy, so he claimed the quality will be great. We'll see about that
