I have a GSP Katana with an OS 160 and i am looking for a motor that is a little bit cheaper to run, I would like to install a MVVS 35 or similar. Has anybody done this and is it a suitable plane for this type of motor. I have had a ZDZ 40 (not in this plane) and didn't like the amount of vibration it produced. Is this what i should expect from gas motors, or are there smoother running motors?

Also i cna't fine any accurate dimensions for the MVVS 35
