RE: UMS Evolution Radial Care and Operation
I started assembling a plane for my EVO 7-77 today - I can't hardly wait to hear that engine run for the first time. I received my prop hub from Tru Turn the other day and I may have ordered it a bit small. I ordered an 1-1/4 hub and it appears that the 1-1/2" hub may have been a better choice. What size prop hubs are some of you folks running on the 7-77 engines?
Best wishes and good safe flying.
