RE: u-can-do 60
I ran mine with 2 1/4 spinner with 14x6 prop originally, then updated it to 2 1/2 with 15x6 prop. the spinner is slighty bigger than the cowl and no one has noticed it. Its been awhile since i did this its either a tru turn or a dave brown spinner and i think i got the adapter from tower hobbies.
