the guy is selling all these used, so no break in issues.
but what about the power difference. you think the OS60 would still be better that the SK80?
I have no clue about this :-)
If the SK80 runs good ,it well be stronger running than the OS 60. However , if you have a very light mechanical background , go with an O.S.75 . an not the .60 . You`ll find the .75 very useful in about any .60 size plane and if you did decide to sell it down the road , it well be more sought after . I highly recommend going with an O.S engine if this is your first one .
If your new to flying ,your odds of having trouble with a used engine are very likely , but there is an upside , you`ll learn deadsticks really fast .
