I'm currently assembling the TF 310 and would really perfer using 4-stroke engines. I'm wondering if 52"s would be adequate. People from Hobby Services are recommending 70's.
Has anyone fitted their 310 with 52's and if so, did they do the job?
Thanks Carl.

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.

Here's mine with OS70 ultimates. Good power.

Thanks for the Photographs. I'm also considering RCV-CD-58"s. I had not thought about YS but will surely consider. I have a YS110 on my TFP40 and am extremely satified with the power. I was concerned with cutting the nacells but yours look pretty neat. Thanks again.

Nice Job!!!
