Too much motor for that plane, IMHO. From your listed weight, that's a .40 sized airframe, so you need to look for a .40 equivalent instead of a .60.

This (https://www.unitedhobbies.com/UNITEDHOBBIES/store/comersus_viewItem.asp?idProduct=666) one would probably be more suitable.

I agree w/ Rick---I have a 72" 6.5 lb AUW 1912 Eastborne monoplane w/ one of these motors & it flys well w/ half throttle on 4s.
Inside the replicated 3 cyl Anzani is the 3520-7
