Default RE: 69" QQ Yak-54

Hi Jose,

Yes a two or four stroke either one would do the job. If you are only flying the plane for 3D, I would recommend a 4 stroke otherwise, an OS1.20AX is also very 3D capable engine and once it's broken in, it will give you a great torque and punch.

At your altitude, you should be fine with either OS 1.20 (rwo stroke) or Saito 1.25 or YS 1.10.

Thank you,
Reza
