U-CAN-DO 3D Performance
 

I am looking for recommendations on the right prop to install on a OS 70II to be used in a U-CAN-DO 46. I'm not looking to do 3D stunts at this time but given the right day! who knows

With that engine I would be using the APC 13 x 6 for general sport flying and possibly some 3D, some guys like it for 3D on this size plane but I thought it had too much "bite" for my likes....

For all out 3D the APC 14 x 4W fun fly prop is king. I have a flying buddy that has one on a Saito .72 equipped UCD 46 and it muscles it around with authority.

My personal preference is for low pitch high diameter props, as the thrust and the propwash make aerobatics (3D or not) so much better. The APC 13x4W, 14x4W are among my favourites. If you cant get hold of those, you could try the 12.25x3.75 C/L stunt prop also, but it may be on the small side for your engine
