I have a CAP X airframe, pondering around what engine I should put in it. Here in Hong Kong we have no shop that sells the DA, and even that now gasoline engines still is not permitted to fly at our field yet. As a result, my choices were limited to only nitro engines. In my minds there are the OS BGX1 or the YS 160DZ Dingo. Which one should I use? Moki is not a choice also as its not available here... All advise appreciated!

I would use the YS engine as I had a BGX and they are junk. I have not seen one run as well as a Marks 2.1 (which was Moki 2.1) or an MDS 2.18. The BGX sucks the fuel likes going out of style. Good Luck

I've had great luck with the OS 1.60 FX with a Perry Pump. But yeah, the best choice is the YS in my book.
