U Can Do 3d With Ys 140
I would like to know from people that fly the U CAN DO 3D with the YS 120 or 140 four stroke engine what mods are needed. How are the flight charactaristics with the heavier engine. Is this engine too heavy?
I am not concerned with Saito information as I am not installing one, so please keep thread about the YS engine and U CAN DO 3D.
