The 9-8 will also notably increase the landing speed of the model, increase the take-off run, reduce vertical capability & reduce its closed-throttle aero-braking capability.
Lots of negative trade-offs for a modest increase in level-flight speed.
I doubt it will increase the landing speed since, at idle, this prop will produce very little practical thrust for this heavy, draggy plane.
Correct - It will increase the takeoff run since it will take a while for that little prop to pull that plane up to speed.
Correct - It will reduce vertical and braking capabilities.
Good bottom line - lots of negative trade-offs.
