RE: Topflite 310 4-stroke powered?
Not OS FS52, but YS FZ63S I plan to use for TF310.
This is the nacelle view of the left wing. The extrusion of the tappet cover on right
nacelle is a bit different due to different thrust angle.
I will use a scale muffler from Hattori(not yet installed). Just for reffernce.
The reason I chose YS was it's size( smaller than OS FS70), yet has enough power
and reliability.
